Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

1. Check fuse F9 20A in the mounting block. 2. At the same time, we check the relay for switching on the windshield wipers and windshield washers (install a known good one for testing, check that the relay is not installed on the other side). A faulty relay occurs when the intermittent wiper mode does not work. 3. Poor electrical contact. There can be many options, for example, the wiring has melted, poor ground contact, poor contact in the block with the wires in the engine compartment due to exposure to moisture, faulty mounting block, etc. We check the presence of voltage on the electric motor pads. 4. The steering column switch is faulty. 5. The nuts on the trapezoid have become unscrewed or loosened. For example, a nut securing the crank to the gearbox axle. Check the windshield wiper trapezoid, tighten the nuts. 6. The windshield wiper trapezoid is jammed. Repair, lubricate or replace. 7. The electric motor is faulty or its fuse (separate) has blown. We check the voltage supply. If necessary, we repair or replace with a new one.

If the windshield washer does not work, check:

presence of water in the tank;
condition of the windshield washer pipes;
relay and fuse F9 20A;
washer motor.

Let us remind you that if you are not satisfied with the operation of the windshield wiper, then by modifying the washer system as a whole, or separately, for example, increase the cleaning area of the wipers or modify the relay.

Have you encountered a malfunction in the operation of your car wipers?

Cleaning the windshield washer nozzles

Windshield washer nozzles also do not often attract the attention of car owners. As a result, many car enthusiasts often ignore these sprayers, which play an important role in car safety. You must remember that windshield washer nozzles are necessary to properly clean your windshield while your vehicle is moving. Yes, windshield wiper blades are also very important. But how the windshield washer nozzles work will determine how the blades clean the glass.

Did you know that those washer fluid nozzles can get clogged? In this case, the quality of windshield cleaning drops significantly. For example, if the nozzle is partially clogged, the windshield will not be washed sufficiently with the windshield washer.

As a result, the wiper blades will not be wet enough, which will lead to poor cleaning of the glass surface. This not only shortens the life of your blades and windshield, but also directly affects your safety while driving. After all, the worse the visibility of the road, the greater the risk of getting into an accident. Also, a dirty windshield puts a lot of strain on the driver’s eyes, which can affect his health.

How to clean?

Car owners should regularly clean windshield washer nozzles to remove dirt. If a blockage occurs, you can use a thin sewing needle to clear the clogged sprayer. However, be careful not to damage the nozzle nozzle. In addition, avoid contact with pressurized water on the nozzle while washing. The fact is that the force of spraying water from a gun in a car wash can lead to a change in the angle of spraying water on the glass adjusted at the factory. In this case, you will have to manually adjust the spray angle to the original position, which is not very easy.

Please give me some advice, I don’t know where to look, all wiper modes work except the fastest. Intermittent and 2nd modes work, they stop in the right place. Only the fastest one doesn’t work.

Still, I had to remove the trapeze with the motor. As a result, the motor jammed (

After prolonged hemorrhoids, flaring, lubrication, etc. he earned it! It took 3 hours.

I checked the relays, fuses and the lever on the steering wheel. Everything is working. It’s a big regret that I’ll have to take off the frill today and see what’s wrong with the motor and trapeze (((I hope I’ll get by with a small amount

trapeze look 100%

check in extreme-fast mode.

if they plow, then the relay may be at fault

and it doesn’t matter what clicks. Thank you

I'll try today

Thank you. I'll try today

This happened to me on 10. The reason was that the wiper motor chip had oxidized. I cleaned it and everything worked

On my first car, the mass disappeared right next to the engine. There are many options for what it could be. And if the relay clicks, it means it’s working.

It’s not a fact that the relay works... there is a microcircuit there that is responsible for the operation of the wipers and one hundred percent of the RELAY)))

Hmm, exactly. I forgot that we were talking about wipers, I was thinking about the standard relay>

the time has come))) so they stopped

Why did it come? I still believe in them

I haven’t taken off the frill yet, I haven’t measured the voltage. The steering switch most likely works because... The washer works and the light switches. The relay may click, but in fact fail?

Firstly, the washer works from a small button in the steering switch and it does not fail, and secondly, what does the light have to do with it? if the light switches on the left switch and the wipers on the right. As for the relay, I think you need to remove it from the donor (working machine) and try it yourself. or buy a new one costs 70 UAH. Does the motor hum when you turn on the wipers?

Checking the motor

If there is liquid in the windshield washer, but it does not come from the nozzles, you need to check whether the pump electric motor is working. If it is in good condition, check the fuse, as well as the wiring. To do this, after de-energizing the battery and disconnecting the pads from the pump motor (as described above), you need to connect the pump motor terminals directly to the battery terminals, observing the polarity. If the pump still does not work, it needs to be replaced, which is usually done together with the motor.

To make the replacement, you also need to first remove the windshield washer reservoir, and carefully pry off the pump with a screwdriver, and then remove it. It is easy to install a new pump, but before doing so it is highly advisable to replace its rubber seal.

How to repair

Remove the dashboard.
Find the relay that is bolted to the body.
Now you need to check whether the fuse responsible for the wiper drive is working.
Then the steering column is disassembled, which makes it possible to see the condition of the switch. Replacement will be required if the insulation is damaged or there are any other flaws.
Now unscrew the motor from the body and check if it is in working condition. If the damage is minor, repair will help, otherwise replacement along with the relay is necessary.
You also need to inspect the drive, since it may be the cause of the malfunction, namely the breakdown of its pulley.

All VAZ-2110 cars have the same windshield wipers. If they are selected incorrectly (more or less), the mechanism will wear out faster and, accordingly, it needs to be replaced or repaired.

You can replace them as follows:

the negative terminal of the battery is disconnected;
the wipers are pulled towards themselves and the brushes are disconnected;
the decorative panel also needs to be removed;
the bolt is unscrewed and the old windshield wiper is removed;
now you need to compare the size of the new wiper and its predecessor;
the new wiper must be identical or at most two more (otherwise there is no point in replacing);
install in reverse order.

Finally, you need to check whether the new windshield wipers function correctly. If they, for example, squeak, something was done incorrectly during the replacement process.

Note: The wipers should operate quickly at high speeds, slowly in intermittent mode.

Do-it-yourself troubleshooting

The main reasons for the lack of washer fluid can be eliminated with your own hands.

Cleaning the injectors

Their replacement and cleaning occurs in the same way and it begins with the removal of these parts, the process is as follows:

open the hood;
make sure that they have plastic plugs; if they are present, they must be carefully removed;
take a flat-head screwdriver and open their spring fasteners to remove the injectors.

Installation of new parts occurs in the reverse order.

To wash the injectors and free them from dirt, you should prepare a special cleaning solution of non-chlorinated water and vinegar, taken in equal proportions. The mixture is mixed well and then poured into the tank. After which you need to press the washer lever, even if the water does not reach the glass, it’s okay. So that the components of the solution have time to break down all the contaminants, you need to leave it in the cleaning system for 2 hours, and then press the lever again. After the dirty solution flows out of the nozzles, rinse the hoses with distilled water.

Replacing the motor

It is quite difficult to repair the motor yourself, so most often it is simply replaced.

Installation of a new device is carried out as follows:

remove all liquid remaining in the tank from the tank;
disconnect the contact between the battery and the pump;
if necessary, you can dismantle the tank, but if manipulations can be carried out with a fixed device, then you don’t have to do this;
remove the electric pump from the tank and unscrew all the hoses going to it, but just remember their location so that after repair they can all be returned to the correct places;
connect a new pump to the system;
screw all the tubes;
connect the battery to the motor;
pour liquid into the reservoir.

Check the operation of the motor by pressing the washer lever; if you hear a whirring sound from the pump, then everything went well.

Mechanical part

It includes:

The brushes themselves - their working part is made of rubber and is subject to fairly rapid wear;
A trapezoid is a structure made of metal guides; they ensure the conversion of the rotation of the electric motor into the actual operation of the wipers. The trapezoid is subject to deformation and clogging of the joints.

Accordingly, from the structure of the windshield wiper assembly, it follows that all breakdowns belong to two groups:

Mechanical;
Electrical.

Consider mechanical breakdowns

If, after turning on the wipers, their electric motor is clearly working, but the wipers themselves do not move or twitch convulsively, then the reason for this is the loosening of the nut securing the trapezoid crank of the wipers to the axis of the electric motor gearbox. Sometimes this nut does not just loosen, but is completely twisted.

The wipers work, but the synchronization and smoothness of their movements are disrupted. In this case, the cause of the breakdown is the so-called “leash”. The nut holding it in place loosens.

Both of the considered breakdowns can be corrected by simply tightening the nut securing the wiper units. Of course, before this you need to put the wipers themselves (their mechanical part) in the correct starting position.

Electrical breakdowns are as follows:

The electric motor does not work completely. After turning on the wipers, you can’t hear them working and the wipers themselves remain motionless. The cause of this breakdown will most likely be stuck motor brushes - then they need to be returned to the correct position. Less often, the armature burns out - in this case, you will have to completely replace both the electric motor and the gearbox (they are sold only as a set).

You can't hear the electric motor running. The wipers also don't move. After they are turned on, only the click of the bimetallic fuse is heard. The reason for this in winter is almost always freezing of the electric motor brushes. Often after this, when persistently trying to turn on the wipers, the bimetallic fuse or, less often, the electric motor armature itself blows. This problem can be easily solved by simply thawing the brushes and removing moisture from them. In more serious cases, you need to replace it with a new fuse or the electric motor itself.

The wipers work, but in intermittent mode they continue to run continuously. At the same time, there are no sounds of alternating rotation of the electric motor armature. This problem is usually solved by simply replacing the control relay. But before doing this, you just need to check and re-clean the contacts of the limit switch - they sometimes oxidize or burn.

The work of the wipers is carried out slowly and with stops in unpredictable places of the working stroke. The windshield wipers do not occupy the lower position at all. In this case, the cause is most often the limit switch - you need to adjust it by bending the contacts. If incorrect operation continues, the electric motor will have to be completely replaced.

All work on servicing VAZ 2110 windshield wipers begins with disconnecting the negative terminal of the battery. After this, the frill is disconnected. It is advisable to do this, since all subsequent operations are significantly speeded up.

Next, unscrew the mounting bolts and remove the entire structure of the wipers by moving them towards you. Their installation is carried out in reverse order.

Replacing wipers

When repairing an electrical component, you must first remove the dashboard to gain access and possibly replace the relay or fuse. After this, you can disassemble the steering column - the switch is located here. It also often needs to be replaced (for example, due to damaged insulation).

Assembly and testing

After the new relay is installed and the winding and armature are cleaned of dirt, you can begin assembly. Here you need to do everything carefully. It is advisable to adjust the rotor immediately so that the blade groove fits into the impeller. If the housing was dismountable, then it is advisable to use new gaskets. The sealant is ideal for both cast and disassembled motors. It is necessary to carefully cover all cracks and holes so that liquid does not get inside.

Next, we connect the pump and check its functionality. It should buzz a little, which indicates its functioning. If this does not help, then the anchor may have burned out. In this case, it is easier to buy a new spare part. First of all, always check the windshield washer pump fuse and only then proceed to more drastic measures.

Do-it-yourself modification and replacement of wipers

Which wipers are better is up to the car owner to decide. Those installed on the VAZ 2110, as well as on the UAZ, do their job well from the factory, but it can be modified with washers from other companies that are of higher quality. Many people are attracted to frameless brushes - this is a good option. They are compact in size and equipped with a special leash mechanism. True, they do not look very attractive on the VAZ 2110, since the fastener to the standard washer arm turns out to be massive. Therefore they need improvement.

Frameless car washers

To perform a replacement or modification, you must perform the following steps:

First you need to disconnect the negative terminal on the battery.
Then you need to tilt the mount towards you and remove the brush.
If there is a decorative trim, it must be removed.
By unscrewing the bolt, you can remove the old brush.
Before replacing parts, be sure to check the dimensions of the new washer with the old one. It is advisable that the new one does not exceed the size of the old one by more than 2 cm.
Installation of the new kit is carried out in the reverse order.

Removing the nozzle

In order to carry out high-quality maintenance, restore the functionality of the nozzle or replace it, first of all, it is necessary to disconnect the wind pad or, as it is popularly called, “jabot”. Or rather, its upper part. To do this, you will need a 10-mm head, a flathead and a Phillips screwdriver.

How to remove the upper part of the windshield

Using a 10mm socket, unscrew the two nuts located along the edges of the cladding.
Next, unscrew the four self-tapping screws that secure the cladding. The screws are located under the plugs.
Then you need to disconnect the sound insulation, which is attached to the wind window trim with six self-tapping screws.
Carefully remove the top part of the windshield.

Having thus gained access to the washer nozzles, we proceed directly to dismantling them.

Attaching the washer nozzles

To dismantle the injectors you must:

Disconnect the washer tube from the tee.
Unscrew the screws securing the injectors, as shown in the photo above.
Remove the injectors.

Now you can perform all further operations with the injectors. Assembly is carried out in reverse order.

The rear window wiper consists of a gear motor, a lever and a brush. Laying the lever with a brush on the left in the direction of travel of the car. The gearmotor contains an electronic breaker relay to ensure intermittent operation of the purifier and a thermobimetallic fuse to protect against overloads. The design of the gearmotor cannot be repaired, therefore, in case of malfunction, it must be replaced with a new one.

The rear window wiper only works when the ignition is on, since the power supply to the wiper circuit is supplied through an additional relay K6

, which is activated when the ignition is turned on.

The rear window wiper is turned on by the switch. 4

(right lever of the steering column switch) in positions VIII and IX (see here). Position VIII of the lever is fixed and in this position the purifier switches on intermittent operation. In the non-fixed position of the IX lever, the purifier operates in continuous mode. In position IX of the lever, the rear window washer electric motor, located together with the reservoir in the right rear part of the engine compartment, is additionally turned on.

For a rear window wiper in continuous mode with a gearmotor load of 1 Nm, a supply voltage of 13.5 V and an ambient temperature of (25±10) °C, the number of double strokes of the gearmotor output shaft should be from 20–30 min –1, and the consumed current strength is not more than 3 A.

In intermittent mode, under the same conditions, the number of double strokes of the gearmotor output shaft should be from 15 to 18 min –1 and the current consumption should also not exceed 3 A. In this case, the first 3–4 swings after switching on should be performed in continuous mode.

Defective injectors

First of all, the car must be installed on a site convenient for work. Defects of the nozzle are carried out by simply turning it on. Using the steering column switch lever, you need to turn on the VAZ windshield wiper and observe the operation of the nozzle.

List of problems with washer nozzles

Washer fluid does not flow through the nozzle nozzle at all.
The washer fluid pressure is very weak.
The jet of liquid supplied is directed to the side and does not provide complete cleaning of the windshield.
The pump supplying washer fluid or its motor has failed.
The washer fluid supply tube is damaged.
The injector has mechanical damage.
The injector nozzle is clogged with foreign material.
The nozzle adjustment is incorrect.

Causes of problems

Attention: In order to quickly determine the area where the defect is located, it is recommended to disconnect the washer fluid supply tube from the nozzle and turn on the washer. If the fluid supply pressure is normal, then the problem is in the injector.

We turn on the brake lights forcibly

Relay K1 is successfully replaced with a pad with jumpers. Its diagram is shown here. If there is no similar platform, you can temporarily close contacts 4-5. First, check everything mentioned above.

A few words about the serviceability relay

The lamp health relay is called K1, and it is the largest in the mounting block. If you pull out this relay, then when you press the pedal you can dial the voltage at terminal five (but not 4). Take another look at the diagram and it will become clear what we are talking about.

The largest relay in the block

All relay contacts are numbered. The voltages at the block terminals are inspected:

6 mass potential;
2 voltage 12, but only after turning on the ignition;
5 twelve by pressing the pedal;
Terminal 4 rings as a ground tap.

If potential 0 is not generated at terminal four, it means that the lamp filaments have burned out or there is a break in the wiring. Now let's look at something else: the mass potential has been found, but the lamps do not glow. Here suspicions arise about a small short circuit.

Installing the rear window wiper VAZ 2112 vertically

Why install the rear wiper in a vertical position? There may be many circumstances. Some of them are simply non-standard. Rear wiper motor (windshield wiper) VAZ 2112. Clutch, tray 2110, repair Repair of windshield wiper blades VAZ 2110, 2111, 2112 this is a forum. On the other hand, the rear window wiper will not freeze in the fall and winter (you can hang the wiper next to the heating grill to prevent it from freezing) Since snow will no longer accumulate on the wiper, visibility will improve, but clearing snow is easier and better downhill than uphill .

Additionally, when the rear wiper is mounted horizontally, it restricts air flow at speed, while in a vertical position, the flow around the rear window improves.

So, installing the rear blade vertically requires: Remove the rear wiper key to “10” (wiper blade bolt) Remove the fifth door trim (the left corner of the dark screw is covered with a pile) Remove the gearbox cover (unscrew the 6 screws, the drive does not need to be removed) Remove the two levers and the washer from the washer, the washer connecting the blood worm to the gears using the wiper shaft. Remove the gear and wash it with lubricant. Remove the current ring by inserting a narrow rod into the holes on the back of the gears. Rotate the ring 180 degrees and mark the cutout under the antenna (attach a ruler to the sides of the antenna and sharpen the hazard on the back with a knife, then untangle the old one). Cut out the old protrusion under the sector with a small chisel and make a new recess in the antenna, as well as in the old antenna hole r and in the disc cutout. Lubricate the inside of the gearbox with lubricant. (for example, Litol 24). Reassemble everything in reverse order. The gear can be set arbitrarily, as it later takes its place after the first use. Alternatively, set the rear wiper position to vertical:

Adjusting the nozzles

If you managed to flush the injectors on your VAZ 2112 car yourself, then you can confidently handle the task of adjusting them. To do this, you need to understand a little about the design features of this device. On a VAZ 2112 car, two types of washer nozzles are used - jet and fan. In turn, jet nozzles can be: single-jet, two-jet and four-jet. This terminology is defined by the method of spraying washer fluid onto the windshield. In the jet nozzles, at the outlet of the washer fluid, a hinged bell is installed. This is a small ball with a through hole. Fan nozzles are equipped with a narrow slot-shaped bell. Now let’s start adjusting the injectors with our own hands:

The direction of the jet in the jet nozzles is adjusted by turning the hinged bell.
We insert a thin wire into the hole of the ball and turn the bell in the desired direction.
Adjustment of fan nozzles according to their design is carried out only in a vertical position; the bell rises or falls to the desired direction. But this is not important; turning them left or right is also possible.

Windshield wiper 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.

Remove the dashboard.
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.
Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
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.
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.
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.
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.

Replacing the VAZ-2112 heater radiator (new model)

The procedure begins with dismantling the stove, which is attached to the car body with two nuts on the side of the intake manifold, a screw in the windshield area and a nut near the cabin filter. It is also necessary to remove the rear window washer barrel.

The sequence of actions is as follows:

Remove the air filter.
Unscrew the screws from the outside of the stove.
The heater body, consisting of two halves (left and right), must be separated and the steam exhaust hose released.
Remove the old radiator, clean its seat, and then install the new element.
The right half of the heater should be disassembled, which also consists of two elements fastened with metal brackets. Now the stove damper is freely accessible, and if necessary, it can be cleaned or replaced.
The new heater damper must be in a position where the heater radiator is closed.
The temperature sensor is set to the minimum mode, after which the ignition is turned on. This is necessary in order to correctly install this sensor, since after this it must take its initial position.
You can reassemble the heater in reverse order.

After replacing the heater radiator, you will need to replenish the coolant level in the system and test the performance of the heater. If everything is done correctly, all heater elements are in working order, and cold air begins to blow from the deflectors in the cabin, which means that the system has become airy. After eliminating it, the stove will work as before, and maybe even better.

Drain the coolant.

We loosen the fastening of the inlet pipeline: we unscrew the cap nuts of the upper fastening completely, and we do not unscrew the two bolts and three nuts of the lower fastening completely.

We loosen the tightening of the self-tapping screw securing the guide tube of the oil level indicator and lift the tube so that its fastening bracket disengages from the self-tapping screw.

Remove the ignition coil of the first cylinder.

1. Disconnect (can be cut) the clamp securing the heater motor power supply wire block and the additional resistor wires.

2. Disconnect the heater motor power supply wire block.

Mechanical faults

mechanics Often the wipers on a VAZ 2110 car do not work due to a banal loosening of the nut that presses the brush holder to the trapezoid shaft.
You can restore the system's functionality instantly by adjusting the angle of the brush and tightening the lever with a nut. An unscrewed nut that facilitates the transmission of torque from the gearbox to the trapezoid can be reported by one of two events:

the electric motor remains operational in all modes, but both brushes do not move;
the brushes spontaneously stop working in an intermediate position.

However, stopping of the brush holders in an arbitrary position can occur due to poor pressing of the “limit switch” contacts to the gear motor gear or oxidation/burning of the same contacts. And the brushes are not able to move even after chipping the teeth of the gears, which do not have a long service life - after all, they are made of plastic.

Windshield wiper failure can occur for quite trivial reasons:

fuse F5 burned out;
the terminals of the connecting blocks are oxidized or burnt;
wires are faulty;
relay K5 524.3747 broke;
ordered the steering column switch to “live for a long time”;
the nut that attracts the trapezoid crank to the gearbox has become loose;
the nuts securing the levers to the trapezoid shafts were unscrewed;
The brushes are frozen to the glass.

Often, wipers on models of the VAZ 2110 family do not work due to complex faults:

oxidation/burning, insufficient pressing force of the contacts of the limit switch located on the gearbox cover;
brushes hanging in the gearmotor;
burnout/contamination of the collector;
break in the armature winding;
chipping of gear teeth in the gearbox.

VAZ 2109 wipers: examination and rehabilitation techniques

The “nine” has a classic windshield wiper circuit: the steering column switch via a relay (intermittent modes) or directly supplies power to the electric motor, which causes the gearbox - crank - trapezoid - brush holders to rotate. Long-term practice demonstrates that

Starter bulkhead on VAZ cars of the tenth model

Problems with starter failure can occur at the most unexpected moment. Since the engine cannot be started, the problem turns out to be quite serious. But you can try to solve this problem yourself. First you need to establish the cause of the malfunction. The main factors for

Causes of motor breakdowns and methods for eliminating them

Every driver faces such a problem when his car breaks down and won’t start. The reason for this is often a malfunction of the starter. It is a specific electric motor that uses a battery to receive power. Main faults and their

Mechanical reasons for device failure

Conventionally, the reasons why the windshield washer fails can be divided into mechanical and electrical. But most often they are quite simple, sometimes you can even recognize them by sound, or carry out a simple check.

Let's look at the mechanical reasons first:

It is likely that the mesh of the cup, which is equipped with the washer reservoir of the VAZ 2110, is clogged with dirt or other deposits, which is why the pump cannot pump the liquid. Here, most likely, you will have to remove the tank, and then see whether the glass with the mesh needs a replacement, or a simple rinsing;
Instead of a special anti-freeze fluid, in the summer they poured ordinary water, and before the onset of cold weather, even after pouring a normal windshield washer, they forgot to remove the water from the hoses. She froze, and accordingly, washing the windshield became impossible. The solution is to warm up the car, leave it in a warm garage with the hood closed and wait until the water melts, then the pump can drive it out;
In the above situation or under other heavy loads, the windshield washer motor shaft may turn. At the same time, a hum is heard from the motor, but the pump does not supply anything to the windows. If this happens, then only replacing the mechanism will help;
The hose has just slipped off, and the liquid does not flow through the nozzles, but somewhere past them;
The hose going to the injectors is pinched;
The injectors (fittings) are clogged with deposits or dirt. To check this, simply remove the hose from the nozzle and see if liquid flows. Replacing the injectors will help.

Instructions for diagnosing, washing and replacing injectors in VAZ 2110-2112 cars are presented here: https://vazweb.ru/desyatka/pitanie/zamena-forsunok-vaz-2110-8-klapanov.html

Why wipers do not work on a VAZ 2110 - reasons and repair methods

You can’t go far without wipers in rain or snow, so today we will discuss the topic of why wipers do not work on a VAZ 2110, and what to do in such a situation.

Device

General structure of the windshield wiper system:

As everyone knows, the wipers are driven into a state of “swinging” of varying speeds by an electric motor, which has a built-in gearbox, and the motor runs on direct current. Three brushes are “built-in” in the motor armature, with the help of which the VAZ 2110 wipers operate in three modes. There are only two speed frequencies: one for fast movement (for example, during a rainstorm), the second for slow or intermittent movement;
The electrical component is the switch (under the steering wheel); relay switching on intermittent mode; additional relay; switch. The entire electrical system is connected by wires (in blocks) through a thermal bimetallic fuse. Moreover, both one and the other relay, as well as fuse F5, are located in the mounting part, and a bimetallic fuse with a limit switch is located in the electric motor gearbox;
Directly windshield wipers. Their size is important, as well as the material, shape, and device. Check whether the already installed ones squeak, whether the mechanism and the leash are working, perhaps they need improvement;
Mechanics. First of all, this is a drive that can break.

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:

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;
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:

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;
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;
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;
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.

Repair

Having skillful hands and basic knowledge of how the wiper mechanism works, there is no need to contact a paid service to make repairs or change windshield wipers. Replacing the windshield wiper motor on a VAZ 2110 is also quite simple.

Reasons why car wipers do not work

Remember how annoying it is when your windshield washer fluid runs out in dirty weather? The only thing worse could be a complete failure of the wipers. Let's figure out why the windshield wiper may not work on the VAZ 2110..

The instructions are suitable not only for owners of VAZ 2110, 2111,2112 cars. Similar causes of malfunctions are found on other machines of domestic or foreign production. The only difference is in some details, such as the name of the fuse or the diagram.

1 – windshield wiper electric motor; 2 – washer motor; 3 – steering column switch; 4 – fuse block; 5 – ignition switch; K2 – relay; A – the numbering order of the plugs in the block of the wiper motor; B – to power supplies. So, we noticed that the wipers stopped working, the procedure is approximately as follows:

Injector maintenance

To ensure uninterrupted operation of the injectors, attention must be paid to them periodically. An extra inspection of the injectors won't hurt. If the injectors have not been turned on for a long time, they must be checked for functionality. Clean and adjust if necessary. In the winter season, it is imperative to use antifreeze washer fluid. Freezing of injectors leads to their wear and premature failure. If you follow the recommendations proposed in this article, then you will not need to replace the washer nozzle on the VAZ 2112 for a long time. And the windshield will be washed as the video shows.

Device design

Wiper circuit

First, let's try to understand how the windshield wiper circuit on the VAZ 2110 works and what components form a solid unit called a windshield wiper.

Device Characteristics Electric motor 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. Electrical components This is a steering column switch, a wiper relay, which allows you to activate the intermittent brush movement mode. Plus, don't forget about the switch. The entire electrical system is integrated into wires running through a bimetallic heat-resistant fuse

It is important to note that both relays and fuse F5 are located in the mounting block, and the bimetallic fuse and switch are in the gearbox of the electric motor. Windshield wipers. At the same time, the size of the wipers on the VAZ 2110 may be different, which we will talk about later. They differ in shape, material of manufacture, design Mechanical drive An important component, which, alas, often breaks on the “ten”

What to do if the wipers stop working due to electromechanics

If the wipers on a VAZ 2110 do not work, the problem may lie in failed gearmotor elements.

The following elements of the electric motor can fail:

Limit switch;
Motor anchor (it could burn out);
Contacts (oxidized);
Springs on motor brushes;
Gears in the gearbox (worn out);
Collector (burnt or dirty).

Repairing wipers on a VAZ 2110, if the cause is correctly identified, will not be difficult.

To do this you need to do the following:

Remove the dashboard;
The relay is screwed to the left of the car body; if it is faulty, replace it;
Check the fuse;
We disassemble the steering column and study the switch. If the insulation is damaged or other problems are present, change the steering column switch;
We take out the electric motor and, if the damage is minor, we carry out repairs. If it requires replacement, feel free to replace it along with the relay.

The wipers on the VAZ 2110 may not work due to mechanical faults.

Quite simple things can prevent the wipers from working properly. For example, such as loosening the nut that secures the electric motor and brush holder. Or weakening the springs of the leashes. The cause may also be the destruction of gears, which is associated with the fragility of the material. As a rule, they are made of plastic.

As a result, we can say that the reasons for the breakdown of wipers are quite simple.

Among the “frivolous” breakdowns, the following can be distinguished:

The fuse in the mounting block died;
The wires are worn out;
The gears are worn out;
The connecting terminals have loosened;
Contacts have oxidized;
The mechanism is dirty.

Such breakdowns are not difficult to repair, and they will not cause significant costs when replacing parts.

Approximate prices for parts:

Relays - from 285 rubles;
Geared motor - from 1650 to 2200 rubles;
Windshield wiper trapezoid - from 1,700 rubles;
Assembled windshield wiper - from 3050 rubles;
Windshield wiper lever (left) - from 435 rubles;
Windshield wiper lever (right) - from 330 rubles;
Brushes from 165 rubles per piece.

All these reasons why the wipers on the VAZ 2110 do not work can be eliminated quickly enough, without extra effort and expense. Of course, the car will let you down if something serious breaks down. For example, combustion of an electric motor, oxidation of contacts that now need to be replaced

It is very important to take care of your car. You need to check the condition of elements such as wipers at least once every couple of days or before getting into the car.

It will be very sad if you notice that your wipers break down during a rainstorm on the highway. Remember: if the brushes freeze to the glass, the electric motor will burn out, then you will have to replace it. Therefore, in winter, be sure to move the blades away from the windshield if you leave your car.

In good weather, no one remembers the car wipers. If there is precipitation, you won’t get far without windshield wipers.

Let's look at the structure of the windshield wiper mechanism of the VAZ-2110 car and dwell on the main reasons for their failure. We will also consider the nuances of repairs and alternative solutions to increase the efficiency of wipers.

Causes of washer malfunction

If the windshield washer does not work, it will not be difficult for an experienced driver to identify the cause of such a malfunction, and even a beginner, after familiarizing himself with the main failures in the cleaning system, will be able to eliminate them on his own.

Mechanical problems

The most important reason, as mentioned above, may be the lack of washer fluid; in this case, you just need to top it up. If it is present, but does not splash in the winter, then perhaps it is simply frozen. In this case, the problem can be solved in one of two ways:

warming up the engine;
bringing the car into a warm garage.

After the liquid has thawed, the system will begin to operate as usual, but it is better to drain the water from the tank after this and replace it with an “anti-freeze” one.

It's not a trapezoid, but a thermal fuse that is located in the motor itself; usually it burns out and problems such as low speeds in all modes, sticking or stopping of the wipers! This can be treated in two ways: 1 - replacing the motor (an expensive method) 2 - disassemble the motor and remove the fuse from there, winding the incoming and outgoing wires from the fuse together! (The fuse is a small black box that looks like a microcircuit) good luck!

Quote(Kadastro @ 1.9.2008, 21:11)

And if in the latter mode they only work intermittently? Also a trapezoid? And when I put a relay in the fuse block, the wipers start to drive.

in your case, you need to clean the contacts on the motor, they usually oxidize!

Pump repair or replacement?

The feasibility of repair is determined by the cost of a new pump. A large number of pumps are non-separable, so for repairs you will have to cut them and then glue the plastic case together. To repair it yourself, it is enough to completely disassemble the motor, clean its insides from dirt, corrosion and growths.

Of course, you won’t find spare parts for the washer pump, so the sealing lip will remain old. If it was this that caused the jamming, then within a year the windshield washer will most likely not work again.

Total

Windshield wiper failure can occur for quite trivial reasons:

fuse F5 burned out;
the terminals of the connecting blocks are oxidized or burnt;
wires are faulty;
relay K5 524.3747 broke;
ordered the steering column switch to “live for a long time”;
the nut that attracts the trapezoid crank to the gearbox has become loose;
the nuts securing the levers to the trapezoid shafts were unscrewed;
The brushes are frozen to the glass.

Often, wipers on models of the VAZ 2110 family do not work due to complex faults:

oxidation/burning, insufficient pressing force of the contacts of the limit switch located on the gearbox cover;
brushes hanging in the gearmotor;
burnout/contamination of the collector;
break in the armature winding;
chipping of gear teeth in the gearbox.

The “nine” has a classic windshield wiper circuit: the steering column switch via a relay (intermittent modes) or directly supplies power to the electric motor, which causes the gearbox – crank – trapezoid – brush holders to rotate. Long-term practice demonstrates that
