Lada 2112 Logbook Repair of windshield wiper trapezoid

If it's snowing or raining outside, wipers become indispensable elements of the car.

Wiper elements for VAZ 2110

In our material we will talk about the mechanism of the VAZ 2110 wipers, discuss the main reasons for their malfunction, the issue of repair and the search for alternative options to standard windshield wipers.

How to detect and determine a malfunction

First of all, the car owner notes the impossibility of changing the temperature of the air supplied through the heating system.
To check the condition of the micro-gearbox, it is necessary to supply electricity from the battery to its motor in the middle position. The functionality of the controller is checked in the same way, which also affects the ability to regulate the air temperature. The most obvious sign of a non-working gearmotor is a significant decrease in the rate of heating of the interior. If there is no ventilation regulation at all, then we can talk about problems with the heater wiring.

Problems with the operation of the stove are not always caused by the heater damper motor of the VAZ-2110. You need to know about other reasons so as not to attribute them to a non-working gearbox:

• inability of the electrical circuit to transmit voltage to the engine;
• malfunction in the autonomous control unit of the heating system.

Security elements

Since the wiper drive is electric, its circuit is protected by a fuse. It is located in the main mounting block and is designated F-5. If the wipers of the VAZ-2110 do not work, it is better to always start troubleshooting with it.

The frequency of brush strokes in intermittent mode is controlled by a separate relay. It is also located in the main mounting block and is designated K-2. If the frequency of operation of the “tens” wipers is disrupted, it must be replaced. Trying to diagnose or repair the relay is impractical, since it costs a little more than 200 rubles.

Self-replacement of the windshield wiper trapezoid on a VAZ 2110

Device of a windshield wiper trapezoid
A hot topic for owners of the corresponding model is replacing the windshield wiper trapezoid on a VAZ 2110. Experienced motorists know: this part is subject to rapid wear. more precisely, not the part itself, but some of its components. In particular, the bushings are made of plastic. Whether the design is to blame for this, or some other defects, they wear out much faster than other mechanisms.

Meanwhile, the performance of windshield wipers is a guarantee of safety in bad weather.

Replacing the windshield wiper trapezoid on a VAZ 2110 is a necessary measure that has to be taken to maintain the wipers in working condition. At the initial stage, this problem manifests itself in a weakening of pressure - in other words, the windshield wipers cannot cope with flows of water or heavy snowfall. Returning to the original position is difficult; you can actually feel the strain with which the wipers move across the glass.

The presence of such symptoms indicates wear of the windshield wiper trapezoid mechanisms.

Attempts to repair the part, especially in a makeshift setting, are impractical: the mechanism is too thin, and the plastic bushings cannot be replaced. The only way out is to replace the trapezoid.

The replacement process is simple, but it involves manipulations that require increased attention and accuracy - there is a danger of damage to neighboring components and mechanisms.

We de-energize the car by removing the “negative” terminal. We remove the special wind cover (the so-called “jabot”) and the expansion tank. The latter must be removed at an angle - there is a possibility that some of the coolant will spill out, so it is useful to first drain some of it into a previously prepared container.

Then you need to turn off the gearmotor. To do this, remove the corresponding connector

Carefully pull out the trapezoid (depending on the year of manufacture, it can be attached to two or four studs) and carefully remove it from the air supply box. That's it, job done

Installation of a new trapezoid is carried out in the reverse order.

Before purchasing a part, you need to find out which trapezoid is needed: there are “old” and “new” samples, indistinguishable in appearance. However, there are quite serious internal differences, which makes it impossible to install the “wrong” trapezoid.

However, our mechanics found an interesting way: a small modification (removing “extra” fastening studs on both sides of the body) solves the problem.

Moreover, experts advise installing a trapeze from Priora on a VAZ 2110 - in this case, a rework is also needed, but some cost savings are achieved (spare parts from Priora are cheaper). The modification consists of replacing the wiper arms (on the VAZ 2110 they are slightly smaller).

In addition, the connectors for connecting the electric motor are different. Here you need at least minimal knowledge in electronics, because you will have to install new wiring, reliably insulating it.

Note. that such experiments require a fair amount of technical skill, which most car enthusiasts do not possess. In addition, in this case, the correct operation of the windshield wipers is not guaranteed (there is a danger that the blades will not ensure complete cleaning of the windshield, in addition, there may be problems with returning to their original position).

Conclusion: in order not to acquire a bunch of problems along with a dubious item, we install the original part, without chasing penny savings.

As you can see, replacing the windshield wiper trapezoid on a VAZ 2110 is a very simple task, accessible even to an amateur

Once again, we draw the attention of novice car enthusiasts that all actions must be carried out with the utmost care - especially those related to extraction

It’s unpleasant when problems with the windshield wiper appear at the most opportune moment, for example, the wipers refuse to work, their movements are difficult, or the blades scratch the car’s windshield. You may have to change the purifier trapezoid assembly, but which one should you install to replace the old one?

Main malfunctions of the mechanism and ways to eliminate them

When is windshield wiper motor repair required?

Before removing, checking the motor and replacing it, familiarize yourself with the main faults of the unit:

1. The device does not function, the safety element does not work either, but its integrity does not work. In this case, you must first diagnose the integrity of the wiring and contact connections, and if damage is detected during the diagnosis, they must be eliminated. If everything is fine with the wiring, then you need to check the steering column brush switch; it is quite possible that it has failed. Naturally, the problem may also lie in the electric motor, for example, its contacts are burnt or the brushes are acidified; if this is the case, then it will need to be repaired or replaced. It would not be superfluous to diagnose the wiring that goes to it and the block. It is recommended to clean the safety element or replace it if cleaning does not produce results. If after performing all these steps the system still does not work, then you will need to diagnose the integrity of the winding of the so-called motor armature. If the diagnostics show that the circuit is missing, then either the armature or the entire electric motor assembly is replaced.
2. The brushes do not work, while the safety element is working, and the fuse in the power circuit regularly fails. In this case, the levers are diagnosed - perhaps they cannot work as a result of deformation or freezing of the brushes to the windshield. It is much worse if the failure of the unit is caused by a short circuit in the armature circuit, then you will have to decide what to change specifically - the armature or the gear unit.
3. The device does not operate in intermittent mode. As a rule, such a malfunction is caused by a failure of a relay or switch. In both cases, it is better to replace the failed mechanism.
4. The wipers operate intermittently but do not stop. In this case, the problem, as a rule, lies in the inoperability of the relay or limit switch. If the reason is the switch, then most likely the spring plastic is not pressed to the end by the gear, and in this case it will just need to be bent (the author of the video is Igor Ivanov).

If the wipers stop turning on

When the VAZ 2107 windshield wiper stops working in both positions of the mode switch, you should start looking for the fault with the wiper fuse. It is installed in the electrical network to protect it from overloads that occur during malfunctions, short circuits or increased load on the wiper motor. If the fuse is working, you should check its contacts. Often they are highly oxidized and prevent the passage of current. Cleaning the contacts is simple - you need to remove the fuse and clean the contacts with a knife, screwdriver or sandpaper. Usually these actions are enough, but sometimes the reason lies in a malfunction of the relay, switch or motor. But more on that below.

If the wipers do not work intermittently

This problem is associated exclusively with a malfunction of the VAZ 2107 wiper relay. The cyclic operation of the wipers is ensured by closing/opening the relay contacts and, accordingly, the power supply circuit of the wiper motor.

The test should begin by monitoring the power supply to the relay block. This is done like this:

• remove the relay;
• turn the wiper switch to the intermittent position;
• Use a control indicator to check the presence of voltage at the terminal.

Replacing the trapezium wipers of a VAZ 2110

Champion Winter Wiper Blades

I don’t think anyone will argue with the fact that good visibility is necessary to drive safely. To do this, it is necessary that the mechanism driving the brushes works, the trapezoid of the wipers is in good working order, but the brushes themselves must be in good condition and appropriate for the time of year.

Bad weather reminds us to regularly replace our windshield wiper blades. Some manufacturers of these extremely important parts recommend changing brushes once a year. The fact is that under the influence of the environment, rubber inserts gradually dry out and lose their elasticity. Hard rubber works like a scraper, leaving streaks and streaks on the glass. Run your finger along the blade of the eraser; if it is worn out and dull, you need to replace the brushes. Don’t skimp on small things and replace dry or worn wipers before the slushy season sets in.

Types of wipers

Classic.

The design consists of seven metal “rocker arms” arranged pyramidally. The largest arc holds two smaller ones, which, in turn, hold even smaller ones and are attached to a rubber blade. This design allows the downforce of the wiper to be evenly distributed. Slowly going out of fashion, these wipers are falling in price every day, while performing their functionality very well in the warm season. The main enemy of such a wiper is snow. But it is impossible to say that these brushes are worse in functionality than frameless ones. The pressing effect of such a design loses its properties over time. Therefore, it is better to change the brush frame itself after a few years.

Frameless.

The “rocker arm” system for this type of wiper is replaced by a thin metal plate that passes through the entire length of the brush. It is a frame, despite the so-called frameless classification. They tolerate snow better, but this design has a disadvantage - the distribution of downforce here is worse than that of “rocker arms”. In the cold there is a shrinking effect. The advantages of these brushes over the previous ones can be called design. Although the taste and color as they say... .

They repeat the classic summer design, but all its moving parts are hidden under a rubber cover. But these brushes are not very suitable for summer, since the casing causes too much windage. If the speed is above 90 km. at an hour, the brushes begin to move away from the glass. As good as such brushes are in winter precipitation, they are just as bad in summer precipitation.

These brushes are the latest development for today. Metal “rocker arms” here replace three plastic arcs, they also act as a winter cover, thereby allowing these wipers to be called hybrid. Another distinctive feature of these wipers is improved aerodynamics. Headwind increases downforce. Although in such a design there is something to freeze on.

In conclusion, we can say that in winter it is better to use winter wipers, and for summer any wipers except winter ones are suitable. It's up to you to choose

In any case, new wipers, no matter what design, are better than those that do not perform their functions at all

Replacing the windshield wiper trapezoid on a VAZ 2110

1. Disconnect the “-” battery cable.2. Remove the windshield trim and trim3. Remove the expansion tank

4. Disconnect the wiper motor connector.5. Then, using a 10mm wrench, unscrew the nut of the left......then the right one securing the cleaner to the car,...

6. Unscrew the bolt securing the wiper motor bracket.

7. After this, remove the trapezoid from the studs and remove it from the air duct housing.

8. Using a 13mm wrench, unscrew the nut holding the crank.9. Using a 10mm wrench, unscrew the 3 bolts holding the engine to the bracket...... remove it.

Which brushes to choose

Standard VAZ-2110 brushes consist of three elements:

The frame of the device is made of metal and has a composite structure, which includes one main rail and two additional ones located on it. The brush is made of soft rubber. In the middle of its working surface there is a longitudinal protrusion (keel), which, in fact, cleans the glass. The brush is attached to two additional frame slats, fitting into their grooves. To ensure that the wiper slides easily across the glass, some manufacturers coat its working part with graphite.

In the center of the main rail there is a fastening mechanism with which it is attached to the leash. It is a guide into which the hook of the leash hooks and a plastic latch that secures the connection.

Having decided on the size of your wipers, do not rush to buy the first model you come across. The fact is that the auto parts market today is filled with fakes. By skimping on some 100 rubles, you can buy wipers that will work effectively for several days, and after that they will begin to creak and let water through.

Windshield wiper repair

Lada Priora hatchback Logbook Steering rack repair

In practice, repairing wipers on a VAZ 2110 is not at all difficult if you have at least basic experience in working with a car and its electrical components.

First, let's figure out how to remove the wipers on a VAZ 2110. The design provides several fasteners, by unscrewing which you can easily remove the wipers themselves.

But with disassembling the windshield wiper assembly, everything is a little more complicated. It is analyzed as follows.

1. Remove the dashboard.
2. On the left side, find the relay that is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
3. Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
4. Disassemble the steering column to allow you to examine the state of the switch. If the insulation is damaged or there is other damage, replace the unit.
5. Unscrew the electric motor from the body and check it in action. If the damage is not serious, it can be repaired. It's better to immediately replace it along with the relay.
6. Check the drive. It is not uncommon for a pulley to break on it, which is why the device has to be replaced with a new one.
7. Make sure the trapezoid is in good condition. It may be necessary to replace the windshield wiper trapezium on a VAZ 2110 if, during operation of the car, the lubrication of the device has deteriorated and all kinds of debris and water have gotten in there. If the lubrication does not work properly, the plastic bushings of the hinges wear out, causing play and increasing resistance during operation of the device. The trapezoid itself serves to transmit force from the electric motor to the windshield wiper arms.

Causes of malfunction

Therefore, if the brushes are completely frozen, or only squeak, the root cause should be sought in the electric motor. Not forgetting that in addition to electrical problems, there may be mechanical problems.

The most common ones are:

1. When you turn on the windshield wiper, you can hear the motor running, but it only jerks or remains motionless. First of all, you need to suspect that the nut securing the crank to the gearbox axle has become unscrewed or loosened;
2. If the windshield wipers operate but are not synchronized, the leash may be the culprit. Most likely, the nut securing it has become loose. Before tightening it, you need to put the wipers in the correct position.

If the electrical part is faulty, the symptoms will be:

1. The wipers work slowly, stop wherever they want, and do not want to take the lower position. The limit switch may be to blame for this. Its adjustment consists of bending the contacts. If such repairs do not help, then the entire electric motor assembly needs to be replaced, since it is sold only together with the gearbox;
2. Intermittent mode is turned on, but the brushes work without stopping. Most likely the relay has failed and needs to be replaced. This is definitely a relay if on a VAZ, when the intermittent mode is on, the noise of the rotating armature of the wiper motor is inaudible. But if the replacement did not help, the contacts of the limit switch may have oxidized or burnt;
3. You turn on any of the modes, and you only hear the thermometallic fuse click. The brushes “stand still” and the anchor is also inaudible. First of all, check to see if the brushes are frozen and therefore do not move. By the way, fuse F5 often blows in this case. Another possible reason is that the anchor burned out;
4. The electric motor does not work, although both fuses are intact. It is necessary to check all the contacts that the drive has, as well as the motor. Perhaps the brushes are stuck or the armature is burnt out.

Purpose and design of the gearmotor

The VAZ 2110 heater gear motor (or servo drive) is used for automated control of the interior heater damper. The heater damper regulates the temperature of the air supplied to the vehicle interior. This innovation from AvtoVAZ replaced the outdated cable system used to control the heater damper in classic models.

The VAZ-2110 gear motor is available in two versions: new and old. The old-style motor is metal, with a rod for connecting to the damper drive. The new type of gearmotor is plastic, with a shaft shank that connects directly to the damper mechanism.

The design of the gearmotor is simple. A motor, housed in a plastic or metal case, with a rated voltage of 12 volts, rotates a system of toothed plastic gears. The purpose of this system is to reduce the speed of the output shaft and increase the torque on it. The output shaft acts on the thrust or damper drive.

The heater drive is controlled by an electronic control unit, which is located on the dashboard under the heater control knobs. The motor is reversed by changing the polarity of the supplied voltage. Feedback to the control unit is provided by a position sensor.

The gear motor of the VAZ-2110 stove is located on the left side of the engine compartment under the upper plastic protection. Attached to the stove body with three screws.

How to remove the windshield wiper trapezoid

To remove the trapezoid you will need:

• key to 10;
• thin flat screwdriver;
• crosshead screwdriver.

First of all, you need to remove the wipers. To do this, you need to remove the plastic pads and unscrew the nuts with which they are attached to the trapezoid studs. Then unscrew the screws and side fastenings of the protective casing (jabot) and remove it. If the fasteners do not come out, treat with WD-40.

Remove the belt that supports the radiator tank and move the tank to the side. Then pull out the partition (sound insulation), which is located behind the tank. Don't forget to remove the washer fluid supply tube from it. Disconnect the electric motor power connectors. After this, unscrew the bolts securing the trapezoid and electric motor.

To remove the trapezoid, you must either struggle for a long time, coming up with various options, or place a thin flat-head screwdriver under the far end (relative to the motor) of the lower rod of the trapezoid and pull out the entire structure as if on a slide. You can also turn the left edge of the trapezoid clockwise and pull it out, then remove the engine.

Photo report on the removal and installation of the windshield wiper trapezoid on a VAZ 2110-2112

When all the preparatory steps are done, everything will look something like this. The arrows at the top show the attachment points of the two nuts:

You need to unscrew them, of course.

After this, we disconnect the clamp securing the expansion tank and, lifting it up a little, move it to the side to gain access to the third trapezoid mounting nut.

After this, the nut can be unscrewed; it is located at the very bottom:

After you have dealt with this, you can carefully turn the trapezoid and remove it from the left side, slightly bending the metal frame below the windshield to the side (the force required is very small - there is no point in talking about any real bending!)

And lift it almost all the way to take it out:

All that remains is to disconnect the power plug:

And now you can finally remove the entire structure of the trapezoid and the wiper motor from the bore. If you need to disconnect and replace one motor, then in principle there will be no difficulties with this - just unscrew it and replace it.

Installation of all removed parts occurs in the reverse order. It is worth mentioning the prices of these spare parts. The cost of a trapezoid assembly with an engine for a VAZ 2110 is about 2000-3000 rubles from the manufacturer AvtoVAZ. Publication 'Repair kit for windshield wiper trapezoid VAZ 2110': Repair of trapezoid. Chinese analogues cost about 2000 rubles.

What are the causes of breakdowns?

The most likely factor causing the wipers to stop is the blown working element in the fuse. Eliminating this malfunction involves performing the simplest action - replacing the fuse link. It is located in the corresponding mounting block, located on the left side of the steering column. It will be useful to stock up on a fuse diagram, which will help you easily find the insert we need.

When the purifiers stopped functioning intermittently, the control relay most likely became unusable. This component is also located in the previously designated block. When a relay fails, it is replaced with a new analogue. However, we note that according to numerous reviews from owners of domestic small cars, certain statistics have been formed indicating the small number of cases of breakdowns of this kind.

The most common cause is the destruction of bushings. They are made of plastic, so they do not boast a long service life, which reaches a maximum of three years. The process of destruction of elements is primarily influenced by the quality indicator of the material. Here, the only effective measure is replacement, and to carry it out you should acquire a repair kit, which is available at a specialized retailer. In this case, the trapezoid is replaced.

If the owner of a Lada Kalina discovers that the wiper drive is not working, this indicates that the unit’s motor has failed. In order to verify this fact, you will need to make sure that voltage is supplied to the motor contacts from the on-board network. This procedure is easily performed using a regular tester. If there is power, then we definitely change the motor.

Interchangeability of VAZ windshield wiper trapezoids of the tenth family

For the “ten” there are old and new type windshield wiper trapezoids, catalog numbers:

1. 2110-5205015
2. 2110-5205015-01
3. 2110-5205015-11
4. 2110-5205015-20
5. 2110-5205015-21

In appearance, the sizes of the windshield wipers are the same, but the sellers claim that they are incompatible, and what should you do if it is no longer possible to find an old-style trapezoid? In fact, there are differences in these windshield wiper trapezoids, but with minor modifications they become interchangeable. To install a new type of windshield wiper trapezoid instead of the old one, you only need to cut off one mounting stud on each side of the body.

In addition, on the “ten” you can install a Priora windshield wiper trapezoid; by the way, it is cheaper than the original one. The differences will be: 1. In the studs for the windshield wiper arms, on the VAZ 2170 trapezoid they are “13”, and on the VAZ 2110 they are “10”, accordingly you will have to replace the wiper arms.2. In the wiper motor connectors. Connect according to the color of the wires (the photo shows a temporary connection method; ideally, all wire connections should be well insulated).

Part of the old and new sample

Therefore, it is better to remove the old part and take it to an auto parts store. They are not only attached differently, but also differ in the connectors through which they are connected to the motor. If you can’t find an old-style trapezoid, and this is exactly what you have, you’ll have to redo the system or look for a used part.

As a rule, trapezoids of a new type are available for sale from various manufacturers. One of the popular models has the article number VLT2110–5205010-Р.

If the windshield wiper motor is working properly, you can only change the trapezoid itself.

We increase the cleaning area of ​​the VAZ 2110 windshield

If, in addition to the left pillar, you add a dirty strip that dozens of wipers cannot clean, then the driver’s visibility is significantly reduced, especially when turning left.

On cars produced recently, this sector is cleaned better by wipers. You can increase the windshield cleaning area in various ways, it all depends on what the strip of dirt looks like that the wiper cannot reach.

I'll start with the simplest method:

Increasing the cleaning area of ​​the windshield (simple method)

Additionally, a raised wiper will only clean the top area near the pillar. As a result, the uncleaned area will resemble a wedge.

Refinement of the windshield wiper mechanism

The connecting rod has a curved shape. It looks like this bend is made at the factory as it turns out (otherwise how to explain that for some the wiper reaches the edge of the glass, while for others it leaves 10 cm). To increase the stroke (amplitude) of the wiper you need to slightly straighten the corners of the connecting rod using a hammer, which the connecting rod will do longer. The longer the elbow (connecting rod), the greater the amplitude (stroke) of movement of the rods. Here is an example when a wiper reaches the edge of the glass with a connecting rod length of 69.8 mm (in your case, the correct length may differ). Therefore, straightening the connecting rod must be done experimentally and it is better not to overdo it with straightening (otherwise the connecting rod will begin to touch the heads of the bolts on the electric motor housing).

We place the connecting rod on the axle, aligning the marks and perform the assembly in reverse order. Be careful not to break the thread when tightening the wiper arm nut. You may have to move the wiper arm on the drive shaft several times until you find a position where the top of the wiper will not touch the windshield rubber in the extreme position.

Thus, by combining two methods (lengthening the rod and bending the leash), you can achieve a result where a large area of ​​​​dirt near the rack turns into a thin strip.

It is important to correctly adjust the extreme position of the blade near the pillar; if the brush is very close to the edge of the pillar, then there is a possibility that at high speed the wiper will simply fly off the windshield (if drains from Priora are installed, then the wiper will physically not be able to fly out) Also for correct For the operation of the windshield wiper, it is important that there is no play in the shaft. Here is the result of correctly setting up and refining the windshield wiper system: By the way, sometimes increasing the stroke of the brushes can be achieved by simply replacing the trapezoid with a new one, and some say that you can increase the cleaning area of ​​the windshield by replacing the trapezoid or leashes from the Chevy Niva.

Here is the result of correctly setting up and refining the windshield wiper system: By the way, sometimes increasing the stroke of the brushes can be achieved by simply replacing the trapezoid with a new one, and some say that you can increase the cleaning area of ​​the windshield by replacing the trapezoid or leashes from the Chevy Niva.

Refinement stages

Wiring

It is easy to modify or replace wipers. To do this you need to take several sequential steps:

• Disconnect the negative cable from the battery;
• Pull the wiper towards you;
• Remove the existing brushes;
• If there is a decorative trim, remove it;
• Unscrew the mounting bolt, thereby removing the old wiper;
• Compare the dimensions of the old and new cleaner;
• Ideally, the new device should not exceed the old one by more than 20 millimeters;
• Reverse the assembly procedure.

As you can see, changing windshield wipers is not difficult. But with the repair procedure, everything is somewhat different. But following the instructions, even an inexperienced VAZ 2110 owner will be able to do everything with his own hands.

Today, no one can be surprised by the presence of a family’s own car. Manufacturers are trying to make their “product” as safe as possible, and this applies not only to the engine and the components that provide movement. The issue of safety sometimes directly depends on the cleanliness of the glass. If the windshield and rear windows are not clean enough, or are covered with drops of water or snow, then you will strain your eyes more and more to fully see the situation on the road. After an hour of driving like this, your concentration will decrease, and this threatens an accident. How can you make sure nothing bad happens? The correct answer is to monitor the condition of the windshield wipers, in particular the trapezoid. This is what we will talk about.

Useful information about the windshield wiper trapezoid

The most important element of the windshield wiper system is the trapezoid. It is this element that is responsible for converting the rotational movement from the electric drive shaft into the translational movement of the wipers. If the trapeze works correctly, then the safety of your movement in bad weather conditions will be ensured. The design of the windshield wiper is quite simple, but reliable and wear-resistant. The main elements of the system are:

- brush and leash;

The design of the trapezoidal wipers on cars from different manufacturers is almost the same. The difference can only be in the dimensions and shape of its various parts. The main elements that create this node are:

Using calculations, designers determine what the profile of the trapezoid links should be. Thanks to this, the structure forms the necessary safety margin, that is, the integrity of the system is maintained when the brushes move. In order to minimize losses due to friction, and to optimize the energy consumption of the electric drive, the trapezoid connecting elements are made of a material based on polyformaldehyde. It produces an extremely low coefficient of friction and is characterized by a high level of wear resistance. To protect metal elements from corrosion, they are coated with a galvanic layer.

When is it necessary to replace the windshield wiper trapezoid?

The incorrect operation of the windshield wiper trapezium, as well as the presence of damage on it, is indicated by malfunctions in the operation of the wipers themselves. For example, they may move too slowly regardless of the operating mode, or stop spontaneously while cleaning the windshield and rear windows. Another clear indication that the wipers are faulty is intermittent movements of the brushes, jumps, and a characteristic sound from the wiper during operation. The main reason for such malfunctions is the presence of oxide on the driver drives in the trapezoid bushings.

It is the oxide that prevents the wipers from rotating normally. If this problem is ignored, then the electric motor, which is subject to a significant load, may also break down, and this entails the possibility of the electric motor’s armature burning out. If there is play in the windshield wiper arms, that is, the arm hits the hood, then rest assured that the trapezoid bushings have worn out.

If you notice even a hint that the windshield wipers are not working correctly, then diagnose the system as soon as possible, and, if necessary, repair or replace the broken unit.

Otherwise, the risk of getting into an accident on the road increases greatly. The need to pay attention to the windshield wiper trapezoid may be indicated by low pressure in the system. If the wipers do not completely remove snow or water, then there is a problem with the pressure.

In order to understand what exactly needs to be done with the trapezoid - change or repair - it is necessary to carry out diagnostics. If you decide to replace the trapezoid, then the new mechanism must be selected correctly. Two trapezoids from different manufacturers can be very similar in appearance, but attached in different ways. The sizes of the leads and the types of connectors for connecting to the electric motor can be different. The conclusion from all this is simple - buy a trapeze from the original manufacturer specifically for your car model.

How to care for your wipers to extend their lifespan

To ensure that your wipers last as long as possible, follow these tips:

• Wipe dirt-stained brushes with a clean, damp cloth or sponge. This way you will not only get rid of dirt, but also protect the glass from scratches.
• If the front glass is covered with a layer of dust and the car washer fluid has run out, do not turn on the cleaner. This will also cause scratches on the glass.

• In winter, especially during snowfalls, do not leave the wipers leaning against the windshield - they will freeze. It is better to raise the leashes so that the brushes are suspended.
• If the windshield wipers are still frozen, do not under any circumstances try to tear them off by force. This will only damage the rubber band. Start the engine, turn the heater on to blow the windshield and wait until it defrosts.
• You should also not knock ice off the frame or brush. Gently bend the elastic until it peels off in small pieces.
• When replacing wipers, place some thick cloth on the windshield. This will protect it in case the spring-loaded leash slips out of your hands.

Wipers do not work on VAZ 2110

It is responsible for rotating the wipers at different intensities. The electric motor contains a gearbox, and the motor itself operates due to the DC current supply. There are three built-in blades in the armature of the engine, providing three operating modes of the windshield wiper - fast, slow and with pauses. Although it is believed that the VAZ 2110 has only two brush rotation speeds

This is a steering column switch, a wiper relay, which allows you to activate the intermittent movement of the brushes. Plus, don't forget about the switch. The entire electrical system is integrated into wires running through a bimetallic heat-resistant fuse.

How to maintain and replace brushes?

To replace the windshield wiper blade 2110, just bend the rocker arm and then unfasten the rubber band. The frame structure itself must be lubricated with silicone oil.

For servicing the rear, the same rules are used. But frameless wipers have an initially curved shape.

The fastening there is done directly along the rocker arm.

Maintenance of brushes consists solely of timely cleaning of salts and derivatives of the washer fluid (dyes may remain after it - in cheap variations). This should be done either with a special solvent or with a solution of citric acid (immerse for 10 - 15 minutes, then wipe thoroughly with a rag). If even after this the brush does not clean the glass properly, it is time to replace it, since it has literally worn down to the ground. At the same time, the pressing force decreases, and the shape of the brush may differ from the initial one.

In general, which wipers are better is up to each individual to decide. With length everything is very clear. It should be remembered that if there are cracks in the glass, the wipers will wear out very quickly, and in order to increase their wear life, the rocker arm should be lubricated with silicone oil in a timely manner.

Alternative solutions

Most car owners of the domestic “ten” are accustomed to replacing worn out and faulty windshield wipers with similar ones.

Often this happens because they do not see alternatives and are not familiar with them.

For all VAZ 2110 models, regardless of the year of manufacture, it is possible to install windshield wipers for the driver and passenger sides of the same size - 20 inches. The length of the brush is 508 millimeters.

But this size can be increased to 530 millimeters. It is not recommended to install more, since this way the windshield wiper will not be able to work effectively, and the drive simply will not cope with the load. As a result, too long brushes cause squeaking and jerky work. Plus, don’t count on a long service life of the wiper mechanisms.

The original windshield wipers for the 10 are quite good. But there are more expensive, but also more highly efficient, high-quality devices.

Today it is fashionable to use frameless wipers, especially from Bosch. Their advantages lie in their compactness and a special, reliable leash mechanism.

But as practice shows, on the windshield of the VAZ 2110, as well as other VAZ models, they do not look very nice, because the fasteners on the leash turn out to be massive. Although if you modify them a little, you will get a very good result.

Brush sizes for VAZ 2114, 2113 and 2115:

On these models, both brushes have the same dimensions and their length is 510 mm. But, it is allowed to install brushes on the passenger side with a size of 510 mm, and opposite the driver with a size of 530 mm. Why different sizes? It’s just that if you put large ones of the same size, this will lead to the fact that a watery strip may appear on the glass when they work together. The rear viewing window is also equipped with wipers that use 300 mm blades. Here the dimensions are not so critical and can be easily replaced with 330 mm.

How to check the gear motor of a VAZ-2110 stove

The easiest way to diagnose is to listen to the operation of the drive. To do this, turn on the ignition and turn the temperature control knob to one of the extreme positions. Then, sharply, in one motion, turn on the other extreme position of the switch. Listen to the central deflector on the dashboard. The motor makes a characteristic buzzing noise.

You can also visually check the operation of the damper. It is visible in the central air duct if illuminated with a flashlight. Turn the switch and watch the flap.

However, these diagnostic methods answer only one question: whether the damper control mechanism works as a whole. The reason may lie not only in the micromotor gearbox. For more detailed diagnostics, you will need to dismantle the motor.

When to change wipers

The service life of the “tenth” brushes is 500 thousand work cycles. If you translate those numbers into the area they could clear, that's 50 football fields. But, be that as it may, it is recommended to change wipers once a year. And it is advisable to do this before the onset of cold weather. Naturally, the wipers of the VAZ-2110 may lose their functionality even earlier. The reason for this could be, for example, damage due to freezing to the windshield or deformation caused by constant exposure to the sun. In such cases, the brushes also need to be changed.

Gearmotor repair

If, however, you still have a desire to repair the gearmotor, and not just replace it with a new one, then the next part of our article will be of interest to you. It’s worth mentioning right away that the details of the new model are significantly different from their predecessors.

Old style part

First of all, let's look at the principle of repairing gear motors on an old-style VAZ-2110. Such a part may have a plastic or metal body. The first option is much easier to work with, but a gear motor in a metal case will be difficult to remove without denting it.

We already know how to dismantle such an element, so let’s proceed directly to disassembling it and identifying faults. We remove the adapter from the shaft, which is inserted into the damper and serves to transmit rotational energy. You can safely pull it towards yourself, since there is no glue or stoppers here.

There are latches along the entire perimeter of the case. To deal with them, you need to use flat screwdrivers, which need to be driven between the latch tongue and the body. Raise the eyelet quite a bit and insert a second screwdriver next to the latch. The halves will open due to the turning movement. Similar actions will need to be performed several times throughout the entire body.

You need to make sure that small parts that may get lost do not fall out. We completely remove the second half of the housing, pull it up from the axle and remove the three gears. On the second half of the housing there should be an electric motor with a gear and shaft.

When removing the electric motor, you need to pay attention to the worm gear, at the end of which there is a segment responsible for centering the shaft and holding the pair of gears in mesh. The item is small and can easily get lost

The motor housing has a locking screw that prevents the motor from turning inside the housing.

We remove the motor, remove the gears and segment from the shaft. We carefully inspect all parts for breakage and defects. If nothing like this is found, then we will examine the gearmotor further. In the place where the wires are connected, the motor parts are secured. We unbend it with available tools and release the bottom part.

Again, we act carefully and carefully so as not to break or lose anything. Inside there is a permanent magnet, which, due to the magnetic field, holds the motor armature in place

In order not to cause trouble, you need to take the unit in your hand and press it with your finger on the shaft. Using the fingers of the other hand, we grab the anchor and separate the motor into parts. Do not grab the windings as they are easily damaged. We see two brushes that are attached to the bottom part. Using a screwdriver, pull the brushes by their holders. At the end of the armature there is a washer that prevents the brushes from being easily removed. There is no reason to remove the washer.

The armature has three windings, which are subject to careful inspection and ringing with a tester. We also inspect all dismantled elements for critical abrasions, melting, and soot deposits.

Reassembling the gearmotor is carried out in the reverse order, carefully and with extreme caution.

New sample part

Dismantling of the new type gearmotor is carried out according to a similar scheme as described above. When the part is in your hands, you need to disassemble the body, which is held in place by clamps. They need to be carefully pryed off with a flat screwdriver. First of all, you need to examine the motor for any malfunctions. To do this, you need to connect it to the connector located in the engine compartment. The micromotor must be disassembled, for which it will be necessary to bend the pressed side

It is important to note the position in which the cover is located relative to the body. This will help maintain the correct polarity of the electric motor during assembly.

If you find a fault in the motor, you will need to look for a break. When the part is running, it is necessary to lubricate it and the gears on the gearbox. Silicone-based lubricant is ideal and can be used over a wide temperature range

It may be necessary to replace the damper position sensor; it is worth paying attention to. Assembly of the part is carried out in strictly reverse order.

Repairing and replacing a heater gear motor is not the easiest job a car owner may encounter. But there is nothing super complicated about this either. If you have the desire, minimal experience and imagination, you can successfully fix the problem with the car heating system and create a comfortable climate in the cabin of your car.

Replacement process

The easiest way to get rid of problems with VAZ-2110 windshield wipers is to contact a service station. There the trapeze will be replaced in an hour or an hour and a half. But if unscrupulous repairmen notice that the owner does not understand the cause of the breakdown at all, they can repair the car for half a day, saying that the problem is very serious.

Therefore, the best option to save money is to replace the part yourself. This process works as follows:

First of all, you will need to dismantle the old trapezoid. To do this, you will have to disassemble and remove the windshield wiper arms. To do this, you will have to unscrew two nuts with a 12mm wrench. When removing the levers, you need to be careful, since powerful springs create a problem when removing them. It is better to bend the leashes first.

Disconnect the wiper motor gear pads.

Unscrew the nut of the left trapezoid fastening.

Unscrew the nut on the other side.

Unscrew the fastening of the gearmotor bracket.

Remove the trapezoid from the studs and remove it.

A new spare part must be assembled before installation, since it is in a disassembled state. When connecting parts, you need to make sure that all parts are aligned and adjusted. Only after this are the nuts tightened.

Before installing a new trapezoid, it is advisable to lubricate all its rubbing parts with graphite lubricant. Some advise using lithol, but it loses its properties at sub-zero temperatures.

If the bushing in an old part is simply worn out, it is not necessary to change the entire trapezoid. It is enough to simply repair it using a repair kit. As a rule, it has everything you need. To repair the trapezoid, you will also have to remove it. When removing the wiper arms, you must try to act extremely carefully, otherwise you may damage the glass or paint on the edge of the hood.

The windshield wipers don't work well Thread starter Avinaim

They work very slowly in any mode! Sometimes they even get up! all bolts are in place! the whole trapeze is lubricated! Tell me what could be the matter? !

Sergey (Miroslawa) Sergey, the driver's windshield wiper was acting up - they replaced the wiper drive under warranty without any questions asked.

Sergey (Miroslawa) In what sense was Sergey bullying???

Sergey (Miroslawa) Didn’t go all the way down and reversed

Stepan (Reece) Sergey, how does the motor work without a trapezoid?

Sergey (Miroslawa) Thank you guys! not relevant! Our warranty service works very well in Nizhny Novgorod! completely changed the motor + trapeze!

Almaz (Ullric) The factory wipers squeak, they say they bend, can you tell me how?

Dmitry (Graciana) Mine also started to work slowly at first, then they completely shorted out and burned out. The motor braid burns out. They will replace it under warranty.

Koblan (Hariwatsa) When the kick-ass left the passenger compartment, the wipers were working slowly, it was still snowing in the month of December, after which they replaced them with frameless ones, now pah pah they run normally.

Timur (Vatsyayana) The windshield wiper on the driver's side suddenly stopped working. As it turned out, the trapezoid had oxidized in one place and had to be replaced. There was no Grant trapeze in the stores, so I had to buy a Kalinovskaya one and play around a little.

Possible causes of problems

Some experts say that if the windshield wiper blades do not work when turned on, the most common reason for this is a failed fuse. In this case, no special efforts will be needed to fix the problem. You just need to open the cover of the fuse box (on the left under the control column) and find the corresponding fuse. This will help create a diagram printed on the inside of the lid.

If the wipers do not work in intermittent mode, then the relay may have failed. It is located in the same place as the fuses. It needs to be replaced with a new one. But, as statistics provided by owners of Lada cars show, fuses or relays blow out quite rarely.

A very common reason for the Lada Kalina windshield wiper blades not working is the destruction of the bushings. As experienced drivers say, plastic bushings fall apart very quickly - their service life is at most 3 years.

Perhaps the prerequisite for their destruction is the property of plastic. But, as annoying as it may sound, there are no other bushings. Repair kits can be found in specialized auto stores.

When the wiper drive does not work, the reason may be the failure of the motor that drives them. To find out whether the electric drive of the brushes has really burned out, you need to check whether electricity is supplied to it. This can be created using a tester. If power is supplied, then it is necessary to change the warmed motor.

Checking a new device

To check the functionality of the new damper motor, set the heater position to the blue dot on the left handle. After waiting about 20 seconds, you need to start the engine. The test cannot be carried out without a multimeter. It is necessary to measure the resistance between X1.1 and X1.4. If the new damper motor is functioning correctly, the voltage will be 800-1200 Ohms (controllers 1333.3854, 1303.3854, 1313.3854), 3600-5000 Ohms (models 1323.3854).

Now you need to check the operation of the damper at the red mark. In the first case, the resistance should be at the level of 3200-5000 Ohms, and in the second - at the level of 1200-1600. In some cases, the absence of the required indicator indicates a malfunction of the sensor. Due to the design features, this element cannot be changed individually; as a result, the entire gearmotor must be replaced.

What affects the condition of the trapezius

The wiper motor and trapezoid are located directly under the glass, so some of the water or washer fluid falls on them. In addition to water, dust, dirt and various small debris get there. All this leads to a change in the properties of the lubricant and deterioration in the performance of the trapezoid. When the lubricant loses its properties, the plastic bushings of the hinges begin to wear out, resulting in backlash and increasing resistance during operation.
