Wipers on the VAZ-2112 do not work: reasons, repairs, photos

An indispensable attribute of the VAZ 2110, like any other car, is windshield wipers. Their colloquial name is “windshield wipers”. Their purpose is to clean the glass from water stains and dirt in case of bad weather.

Of course, the work of wipers is most often necessary in the off-season, when there is the most rainfall. During these periods, without properly functioning windshield wipers, driving a car is not only difficult, but dangerous.

Like any other important component of the VAZ 2110, the wipers need regular inspection and, if necessary, repair. This usually happens once every five years. But you may have to start repairing your windshield wipers earlier - if they start working slowly or don’t work at all.

Repairing windshield wipers is not difficult; any self-respecting car enthusiast is quite capable of doing it himself. Below we will look at algorithms for repairing wipers on a VAZ 2110, and even how to completely replace them correctly. But let's start by considering all the elements that ensure the operation of the windshield wiper:

First stage: diagnostics and elimination of electrical faults

Every owner of the tenth model probably noticed clicks and noise coming from the gearmotor located on the left when activating the windshield wiper system. Therefore, at the initial stage of solving the question of why the wipers do not work on the VAZ 2110, you should pay attention specifically to the nature of the operation of this unit.

The electric motor does not show any signs of operability - it is necessary to inspect fuse F5 in the mounting block located on the left under the headlight beam hydraulic corrector. A serviceable fuse primarily serves as an indicator of problems in the electric drive feeding system.

A multimeter will help you identify the faulty area: you need to “ring” the circuit in resistance mode from the fuse to the gearmotor and steering column lever, and even the switch itself. The multimeter induces zero: the section is serviceable, an infinitely large value is a reason to inspect the terminals and wires.

The malfunction is resolved by the following steps:

• clean/crimp the terminals in the fuse block, contact connectors of the steering column switch and gearmotor;
• replace wires;
• replace the lever on the steering column that activates the windshield wipers.

Relay K2 type 524.3747, located in the mounting block, is responsible for the operation of the windshield wipers in cycles with pauses (I and II positions). The system does not operate in intermittent mode - a reason for a detailed inspection and replacement of the relay. Under such circumstances, the steering column switch should also be “sinned”.

Something to keep in mind! If the relay is defective, the windshield wipers operate completely unprecedentedly in the third extreme position of the right steering column switch.

However, a faulty relay does not always stop the operation of the unit in intermittent mode. Windshield wipers can effectively perform their function in positions I and II, however, the presence of a defect in the relay will be indicated by the absence of pauses between sweeps of the brushes, characteristic of these modes.

Along the way, finding out other reasons why the wipers on the VAZ 2110 do not work intermittently with pauses, you should inspect the limit switch located on the gear motor cover:

• the oxidized layer should be removed;
• burnt contacts must be cleaned;
• Contact petals should be bent if necessary.

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.

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.

Minor tuning: wiper relay with adjustable pause and optical rain sensor

Setup of purchased kits is carried out according to the instructions.
The usual system provides several modes, for example, rain, snow and a standard pause of a few seconds. On-demand operation is not disrupted - if you need a second speed, turn it on. Same with the third one. An alternative to a rain sensor is a relay with an adjustable pause. It costs a penny, it only takes a few seconds to install, and the effect is very good. Electrical equipment allows you to change the pause depending on the conditions while on the road while driving. Another nice bonus is that you can choose a part with a different cycle of operation of the windshield wipers in washer mode.

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.

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

Device

General structure of the windshield wiper system:

1. 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;
2. 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;
3. 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;
4. Mechanics. First of all, this is a drive that can break.

Wiper diagram for VAZ 2110

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.

The reasons for washer failure in a VAZ 2110 car are studied in detail in this material: https://vazweb.ru/desyatka/kuzov/bachok-omyvatelya.html

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).

Often it is necessary to completely replace the wipers. Here you need to remember the following - wipers for all years of production of the VAZ 2110 are identical and interchangeable. If any other wipers are used (for example, foreign-made), then you need to make sure that their sizes match.

The length of the VAZ 2110 wipers is exactly 20 inches (50.8 cm). Their increase by 1 - 2 centimeters will not be critical. But if the size of the wipers is much larger, then squeaking during operation, jerking and early failure are inevitable.

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:

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, then check:

1. presence of water in the tank;
2. condition of the windshield washer pipes;
3. relay and fuse F9 20A;
4. 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? Keywords:

• DIY car diagnostics
• wiper blades

The windshield wiper system on a VAZ 2110 car is the most vulnerable point. Absolutely any component can be a weak point in the system: switch, relay, fuses, windshield wiper motor.

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.

Parsing is carried out in this way:

• Remove the dashboard;
• On the left we find a relay screwed to the body. If the relay turns out to be faulty, then repair is unlikely to help it; a replacement is needed;
• We check the fuse responsible for the wiper drive;
• We disassemble the steering column to inspect the switch. If it turns out that the switch has insulation damage or other problems, it means it needs to be replaced;

• We unscrew the motor from the body and check for functionality. If there is a minor problem, it can be repaired, or perhaps it will need to be replaced, along with the relay. There is no point in repairing the relay separately - its cost is cheap;
• Inspect the drive; one of the possible faults is that its pulley has broken.

Alternative

When choosing wipers, not only their size matters, but also the device, as well as the manufacturer. For VAZ 2110 of all years of manufacture there is one size for the wiper on the driver or passenger side - 20″ (wiper length 508 mm).

However, you should know that you can usually increase the size to 53 cm, but no more, otherwise the windshield wipers will not cope with the task assigned to them, and the drive may fail, because the leash is not designed for such a load. In addition, such wipers creak during operation and can operate jerkily.

If the size is chosen incorrectly, the mechanism will fail faster. In principle, many people use the “original” VAZ wipers and are satisfied with them. But it is possible to modify windshield wipers from other companies, often of higher quality.

For example, for many, frameless brushes (especially Boshevsky ones) are very attractive. They are compact and have a special leash mechanism. However, they do not look particularly nice on a VAZ, since their fastening to the arm of a regular frame wiper turns out to be massive. These brushes need some work.

The VAZ 2112/2111 model has a rear wiper, its size is 11″ (27.9 cm).

Both regular replacement and modification of wipers begin with disconnecting the negative terminal of the battery. Then you need to pull the wiper towards you and remove the brushes.

If there is a decorative trim, it should be removed. Unscrew the bolt and remove the old wiper. Be sure to compare the size of the new windshield wiper with the old one. It will be better if the size of the windshield wiper on the VAZ 2110 does not exceed its predecessor by more than 2 cm. Install everything in the reverse order.

Check to see if the new brushes are squeaking and how they obey the “commands” of the switch. They should work quickly at high engine speeds, and slowly at low and intermittent modes. That, in fact, is the entire repair of VAZ wipers.

Trapezoid

The lever system, which is responsible for transmitting movement from the motor to the brushes, can also fail. The problem may be rusty hinges or simply frozen joints. To diagnose it, you will have to remove the decorative trims under the windshield, called frills. At the same time, check all the wiring and connectors that go to the windshield wiper motor already mentioned above. Be prepared right away for the fact that there will be very little space inside, and all the components are located very compactly and difficult to access - this is the price to pay for comfort and space saving in modern foreign cars. If, upon reaching the trapeze, you find a large amount of ice and snow, then feel free to drive the car to a warm parking lot. Or just prepare two kettles of boiling water to soak the frozen mechanisms.

Windshield wiper device

The function of the electric motor is to move the wipers at the required speed. It has a built-in gearbox, and the engine runs on current, which is supplied uninterruptedly. There are three brushes in the motor armature; they are responsible for the three-mode operation of the VAZ-2110 wipers.

Speed ​​can be selected in two modes:

• fast (designed to work in heavy rain);
• intermittent.

As for windshield wipers, both their size and shape, the material from which they are made, as well as their design play a role. After installing them, you need to check whether they creak, as well as the condition of their mechanism and leash. If the failure is mechanical, it is most likely the drive.

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.

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.

Problems with windshield wipers and their elimination

If the wipers do not work at all, the reason is the electric motor. Although sometimes the breakdown can be purely mechanical.

1. When the wipers turn on, you can hear the motor running, but the motor itself remains motionless. In this case, it is quite possible that the nut that secures the crank to the gearbox is loose or completely unscrewed.
2. When the windshield wipers operate asynchronously, the fault may lie in the linkage. It is necessary to check its fastening. If the nut is loose, you need to tighten it, but first, set the wipers to the correct position.

Electrical faults can be traced as follows:

1. If the windshield wipers work as if by themselves, namely:

• move slowly;
• stop when they want and in the position in which they consider it necessary;
• do not occupy the original place at all.

The reason for this may be the limit switch. The problem is easily solved, you just need to bend the contacts. If this does not help, the entire electric motor must be replaced.

1. If the windshield wipers do not stop while cleaning the glass in any of the modes, then most likely the relay is broken and needs to be replaced. Another confirmation of this may be the operation of the windshield wipers in intermittent mode, so the noise from the armature of the wiper motor is not heard when it rotates. If replacing the relay did not help, it is possible that the contacts of the limit switch have oxidized/burnt out.
2. In a situation where any mode is turned on, but only the clicking of the thermometallic fuse is heard. If the brushes are standing, but you can’t hear the anchor, you need to see if they are frozen, perhaps this is the reason. If so, then most likely fuse F5 has blown. Another possible reason is that the anchor has burned out.
3. If you are convinced that the fuses are not damaged, but the electric motor still does not work, check the drive and motor - either the brushes are stuck or the armature is burned out.

The usual horizontal rear window wiper of the VAZ 2112 can be changed to vertical. How difficult is it to make your own rear windshield wiper vertically? Why change the original position of the rear wiper on hatchbacks and what are the pros and cons of such an arrangement?

Why install the rear wiper in a vertical position? There may be many circumstances. Some of them are simply non-standard. 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 you need to install the rear brush vertically:

1. Remove the rear wiper using a "10" wrench (windshield wiper)
2. Remove the fifth door trim (there is a dark screw hidden by lint in the left corner)
3. Remove the gearbox cover (unscrew the 6 screws, the drive itself does not need to be removed)
4. Remove the two arms and friction washer that connects the bloodworm gears to the wiper shaft.
5. Remove the gearbox and wash it with oil.
6. Remove the current ring by inserting a narrow rod into the holes in the rear of the gearbox.
7. Rotate the ring 180 degrees and mark the cutout under the antennas (attach a ruler to the sides of the antennas and use a sharp knife to create a back hazard, then match the hazards with the old groove under the antennas)
8. Cut off the old protrusion under the sector using a small chisel and make a new recess under the antennas
9. Cut a sector into the old recess under the antennas, and a sector. into cut-out rings from the lid of a jar of mayonnaise.
10. Glue the ring in the new position to the gear and glue the sectors into the old recess under the antennas and the disc cutout
11. Lubricate the inside of the gearbox with lubricant (for example, Litol 24)
12. Reassemble everything in reverse order. The gear can be installed arbitrarily, as it later takes its place after the first inclusion

How to turn on the wipers in a car

The working mechanism is that three contacts are closed by a copper plate, and then the wiper moves to one side, and when the motor opens, the motor starts to rotate in the opposite direction.

Alternatively, set the rear wiper position to vertical: Pull the wiper wire to the parking area (yellow) away from the unit. The rear wiper can now be hung in any position and, if necessary, the wires can be rotated in 5 seconds, bringing the car to its standard state. But you have to catch the position of the rear wiper (it's not that difficult). From time to time, after a few hits, the cleaner may slow down, and after a few seconds it will continue moving.

To ensure that the rear wiper is parallel to the post, you can bend the brush arm. In this case, you can bend the rear window wiper in different ways.

And if you want, you can do it all by removing the rear wiper and replacing the cap.

Since any modification or adjustment has its fans and detractors, it is no exception to change the starting position of the wiper. By the way, you can install the fifth wiper vertically only for the winter, and in the summer turn the blade back to the horizontal position or completely clean the rear wiper.

How to repair

Don't be upset if you find that your windshield wipers refuse to work and run to a service center. In the VAZ-2110, with enough knowledge, you can fix everything yourself.

1. Remove the dashboard.
2. Find the relay that is bolted to the body.
3. Now you need to check whether the fuse responsible for the wiper drive is working.
4. 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.
5. 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.
6. You also need to inspect the drive, since it may be the cause of the malfunction, namely the breakdown of its pulley.

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

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?

Finding Electrical Problems

Each owner of a VAZ-2110 involuntarily paid attention to the clicks coming from the left side and the barely audible noise from the gearmotor when the windshield wiper was running. Therefore, at the initial stage of searching for the reasons why the VAZ-2110 wipers do not work, you need to check the performance of this particular product.

If the electric motor does not show any signs of life, you need to check the fuse located on the mounting block, which is located on the left side, under the headlight switch lever. If the fuse is in working order, this indicates a malfunction in the electric drive feeding system.

A multimeter will help determine the problem area in the circuit. You need to check the circuit from the fuse to the gearmotor, from it to the hydraulic corrector.

Naturally, it is necessary to check the fuse itself. If zero is constantly lit on the multimeter screen and a not very pleasant sound signal is heard, then the circuit is working properly. When several numbers appear on the screen, without sound, we move on - we move on to inspecting the terminals and wires.

You can troubleshoot the problem as follows:

1. Clean and tighten all terminals that were checked with a multimeter.
2. Replace wiring.
3. Install a new lever on the steering column that turns on the windshield wiper.

Relay K2 (5243747), located in the mounting block, is responsible for the operation of the windshield wiper. If an intermittent mode is not observed during system operation, then it is time to change the relay. Under these circumstances, the hydraulic corrector also needs to be checked. If the windshield wiper relay has a defect, it will work wonderfully in the third extreme position of the right steering column stalk. A faulty relay does not stop working in all cases. Windshield wipers can function perfectly if they are turned on in position 1, but the fact that there is a defect and the relay is not working correctly will be indicated by pauses between sweeps of the blades. Often the relay simply goes away, and the wipers and heater do not work at the same time. In this case, you usually need to tighten the contacts.

In searching for the reasons why the wipers on the VAZ 2110 stopped working, you also need to check the limit switch located on the cover of the gear motor. It is also advisable to clean the contacts from oxide and bend the contact petals.

What to do if the wipers don't work

It is performed in several approaches. Necessary:

1. Do the work of disassembling the unit.
2. Determine the breakdown.
3. Depending on the situation, the part is replaced or repaired.
4. At the end of the procedure, the knot is completely assembled.

Checking the wiper relay

When the VAZ 2109 wipers stop working, they also clean the contacts after removing the relay from the mounting block. Afterwards everything is put back in its place. The operation of the mechanism will be indicated by a signal, like a click. In case of failure, the unit should be replaced.

Bimetal wiper mechanism

When the bimetallic fuse was activated, a high temperature was allowed on the motor of the cleaning structure. Therefore, the bimetallic plates opened. And when the temperature drops, the wipers resume normal operation. However, the fact that the windshield wipers of the VAZ 2109 do not work requires that the work be completed. To ensure that excessive heating does not recur, check the entire structure

It is important to find the cause of the heating and eliminate it

To carry out this work, you should install:

• service life of the lever system;
• determine the degree of wear;
• wash and lubricate the levers.

Motor wiring

In the wiper motor, you can easily detect irregularities in the wire winding by connecting directly to the battery. The motor is working properly.

Electromechanical problems

An electric motor that shows no signs of life, no click and a blown fuse F5 - all these problems indicate faults in the gearmotor, which can be eliminated by replacing one of the components:

• dirty collector in the electric motor rotor;
• brushes that ensure continuous contact in the motor;
• burnt collector;
• broken armature winding.

There are other options: the electric motor does not want to work, but there is a click, or the fuse blows. In this case, you need to return the left lever to its base position as quickly as possible, since these problems indicate a short circuit in the electric motor. It needs to be completely changed. With the same problems, there may be minor faults: brushes frozen to the glass, or wipers touching body parts. Under such circumstances, you need to carefully separate the brushes or straighten their mounting arms.

Mechanical problems

Often the windshield wiper on a VAZ-2110 may not work due to a loose nut pressing the blade holder. This fault can be repaired in a few seconds. It is enough to tighten a poorly tightened nut to restore the functionality of the wipers. Some events may indicate an unscrewed nut:

1. When the electric motor is running, the brushes do not move.
2. The brushes stop working on their own in an intermediate position.

Also, brush holders may stop due to poor contact pressure in the gearmotor. If the teeth on the gearmotor gear are crumbled, the brushes will also not work.

Quick diagnosis by weight

The ground outlet is located on the lower bolt of the windshield wiper drive, in the sump. If you suspect that the problem is a bad ground, turn the windshield wipers on maximum and note the speed of their movement. Then turn on the stove. The heater and wipers are connected to the same ground output, so if this is the problem, the speed of movement of the wipers after turning on the heater will decrease significantly.

To fix the problem, find the ground outlet, clean the contacts, solder the terminals if necessary, coat the connection with protective grease, and tighten the fastening nut well.
