What to do if the wipers on a VAZ-2110 do not work: possible reasons

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.

The wipers do not work, the sound of the motor is not heard

Most likely, the problem should be looked for in the gearmotor itself. To check the electric motor that drives the windshield wipers, it must be removed. First you need to check the fuse on the motor itself (it can be either directly in the gear motor or somewhere near it). You should try to connect the removed wiper motor directly from the battery: if the motor does not come to life, then the problem lies with it. Moreover, most often the motor does not require replacement: it can be overhauled by replacing the brushes or lubricating the entire mechanism. If the motor is working properly, the reason may also be in the steering column switch or in the wiring. You can check the serviceability of the steering column switch using a tester: disconnect the wiper wiring block and connect a tester to check the presence of voltage when switching wiper operating modes.

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.

How to check the wiper relay on a VAZ 2110

Hello.
Yesterday the intermittent wipers stopped working. I wanted to brush the snow off the glass (I’ve done this a hundred times), but they twitched a little and that’s all. When you spray on the glass, the wipers are also silent. The relay clicks. Fast and slow work, but when turned off they stop where they turned off, without returning to their original position. Where should I look? There was a relay that clicked, but it didn’t work either, the contact group in it was burnt out. it worked once.

at the same time, what it is and what it is not. without it, the wipers only move in the third position. You can unhook it altogether and check how it goes

There was such a thing. I drove in heavy rain and the wipers failed. Only the fastest mode worked.

I also thought about the relay (the relay also clicked) and the motor. I bought this relay and installed it. but there's no point. I was already planning to buy a new windshield wiper, but I decided to check the contacts first. Is current supplied to the motor?

It turned out everything was banal. The terminals oxidized a little and the contact was lost. I took everything apart, cleaned it and lubricated it. work fine! Hemorrhoids are only full with analysis of Shumka and toad

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.

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.

• 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.

• 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.

• 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.

• 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, which 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.

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.

This material will help you figure out why your car windows sweat: https://vazweb.ru/desyatka/salon/poteyut-stekla.html

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.

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”.

Additional fuses and relays

Location

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.

If the wiper does not operate intermittently:

• disconnect the positive terminal from the battery;
• remove the decorative panel on the left side of the car, next to the hood release handle. There is a relay under the panel;
• unscrew the two screws securing the relay and disconnect the connector;
• install a new relay;
• putting everything back together;

In this guide, we did not touch on more complex troubleshooting diagrams for the windshield wiper system. Such as replacing the winding and armature of an electric drive or overhauling a windshield wiper gearbox, because this is a more complex task that requires certain special skills. With the modern availability of spare parts, it is easier to replace the entire unit than to repair it.

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

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:

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

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.

Circuit breakers

Now let's see which fuses are responsible for what in the same mounting block. I will also give the main reasons for troubleshooting.

F1 (5 A) - license plate lighting lamps, dashboard lighting, side lights on the panel, trunk lamp, left side lights . If any of the listed lamps do not work, check this fuse, as well as the lamps themselves and their contacts. If everything is in order, check the headlight switch button.

F2 (7.5 A) - low beam in the left headlight . If both low beam headlights do not work, also check relay K4 and the lamps themselves. It could also be the light switch and its contacts.

F3 (10 A) - high beam in the left headlight . If both high beam headlights do not work, check the K5 relay, the lamps themselves and the high beam switch knob.

F4 (10 A) - front fog lamp on the right side . If both fog lights do not work, check relay 9 and the headlight bulbs themselves, as well as the switch and its contacts.

F5 (30 A) - window lift motors . If the power windows do not work, check this fuse and relay 5. In winter, check if the windows are frozen, warm them up and clear them of ice if necessary. It could also be the window lift motor, its mechanism and gears; in order to get to it, you need to remove the trim of the desired door.

F6 (15 A) - portable lamp fuse.

There may also be problems with the cigarette lighter. To check, unplug the cigarette lighter from the connector. If this fuse stops burning, then the problem is in the cigarette lighter.

F7 (20 A) - engine cooling fan, sound signal . If the cooling fan does not turn on and the engine overheats, check this fuse. Also check the operation of the fan motor by connecting it directly to the battery. It could also be the coolant temperature sensor or thermostat.

F8 (20 A) - heated rear window (element) . If the heating does not work and the rear window fogs up, check this fuse, fuse F9 and relay K7. Also check the contacts on the terminals of the heating elements, check the wiring, sometimes the wire frays. It could also be the heating switch and its contacts.

F9 (20 A) - recirculation valve, windshield wipers and washer, headlight washer, rear window heating relay coil . If the heating does not work, similar to the previous one. If the windshield wipers or washer do not work, also check relay K2, the fluid level in the washer reservoir, the washer pump, and the wiper motor. Another issue may be their switching handle, its wiring and contacts. The wires may be squashed or frayed and shorted to the housing.

F10 (20 A) - backup fuse.

F11 (5 A) - right side dimensions . If the left side does not work, check fuse F1. If none of the side lights work, check the light switch and its contacts. Also check the dimensions of the lamps themselves.

F12 (7.5 A) - low beam in the right headlight . Similar to fuse F2 for the left headlight.

F13 (10 A) - high beam in the right headlight, high beam lamp on the dashboard . Similar to fuse F3 for the right headlight. If the blue lamp on the panel does not light up when you turn on the high beams, check this fuse, as well as the lamp itself and the wiring to it.

F14 (10 A) - front fog lamp on the left side.

Similar to fuse F4 for the right fog light.

F15 (20 A) - seat heating, trunk locking . If the heated seats do not work, check this fuse and the power button on the dashboard, its contacts and wiring.

F16 (10 A) - direction indicators and hazard warning lights, hazard warning lamp . If the turn signals or hazard lights do not work, also check relay K3 and the lamps in the turn signals themselves, as well as the hazard light switch button.

F17 (7.5 A) - interior lighting, lighting, ignition switch lighting, brake lights, clock, on-board computer . If the brake lights do not work, check this fuse, the lamps themselves, and also the switch installed in the pedal unit.

F18 (25 A) - glove box lighting, heater controller, cigarette lighter . If the cigarette lighter does not work, check this fuse, disassemble the cigarette lighter and check for a short circuit in it, especially on the washer and contacts. Bend them if necessary or replace the entire cigarette lighter. Do not insert non-standard size connectors into it.

F19 (10 A) - door locks, control relay for brake lights and parking lights, turn signals and lamps for turning them on on the panel, reverse lamp, generator winding, control indication of the on-board system, dashboard, clock, on-board computer.

F20 (7.5 A) - rear fog lights.

If the rear fog lights do not work, check this fuse and relay 9. Also check the lamps themselves, wiring, connectors and the switch on the panel.

Never replace blown fuses with fuses of a higher rating (current), this can cause burnout of tracks on the mounting block, failure of devices, etc. In this case, repairs will cost more, so it is better to deal with the problem immediately and fix the problem. If you cannot find what’s wrong on your own, contact a car service; usually such problems are dealt with by electricians, who will not have any difficulty identifying the problem and fixing it.

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.

Why does the windshield washer not work?

All washer malfunctions are divided into two groups: electrical and mechanical.

Mechanical:

• Lack of liquid. In winter, you cannot use ordinary water, as it may freeze. If the water still freezes, you need to warm up the car engine and leave it in a warm room.
• The fluid supply hose may fly off or become pinched.
• The nozzles can also stop the washer from working. Poor quality of water and washer fluid leads to the fact that the fittings become clogged with dirt, rust, and washer fluid does not flow. The injectors are cleaned or new ones are purchased.

Read, it may be useful: Hood deflector

Electrical:

• Fuse F2(10A) has blown.
• The electric motor does not pump, no fluid flows, which means the terminals are oxidized. You need to clean the terminals and contacts and connect everything.
• Faulty switch. If the motor does not turn when voltage is present, then this is the reason.
• Check the pump motor by connecting it directly to the battery; if it starts spinning, then the fault is in the steering column switch.

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.

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.

Wipers do not work on VAZ 2110 - reasons and repairs

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:

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.

Unscrew the fixing nut

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.

Electrical part

It includes:

• The electric motor of the windshield wiper itself;
• Windshield washer motor;
• The windshield wiper and washer switch is located under the steering wheel of the VAZ 2110;
• The main and additional relays are located in the mounting block and provide cyclic operation of the wipers;
• Bimetallic fuse is thermal in type; its limit switch is located in the gearbox of the windshield wiper motor.

Device design

ten The three-speed windshield wiper system is one of the most vulnerable in the domestic “ten”. Almost any component can play the role of a weak point: steering column switch, relays, fuses, gear motor.

The design of the windshield washer on the VAZ 2101 consists of a gearmotor powered by an incoming current that drives the washers, a switch, a switch, a relay for switching on the intermittent mode, an additional relay, etc.

Glass cleaner device

The node consists of:

1. Windshield wiper trapezoids: with its help, the motor transmits movement. It wears out quickly, so sometimes repairs to the trapezoid are necessary.
2. An electric motor drives the wipers of the VAZ 2110. If the motor burns out, the entire unit will fail.
3. The windshield wiper pump pumps cleaning fluid. If the electric pump breaks down, then, despite the operation of the wipers, the windshield will not be cleaned.
4. The purpose of the tank is obvious - window cleaning liquid is poured into it.

Thanks to the electric motor, the wipers on the VAZ 2110 can operate in three modes:

1. Intermittent. The switch lever is in positions II and III.
2. Constant - with a low speed of movement of the brushes. The switch lever is in position IV.
3. Constant - with fast movement of the wipers. In this case, the shift lever is in position V.

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.

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:

1. Mechanical;
2. Electrical.

Consider mechanical breakdowns

1. 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.

1. 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:

1. 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).

1. 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.

1. 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.

1. 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).

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 reason for this is that the permissible mass-dimensional load is exceeded.

Engine repair

Many people think that replacing the engine with a similar one in a foreign car can solve the problem of slow wiper operation, but in fact, cleaning and lubricating the “original” engine is quite simple.

READ The heater on Kalina doesn't heat well.

If the grip is causing speed, you need to check how easily the armature rotates: if movement is difficult, damage to the brushes or excessive wear on the brushes should be suspected. They are easy to exchange for new ones.

Cleaning the manifold will also help. You will need fine sandpaper. The need for this procedure is said:

• Visible contamination;
• Noticeable scratches;
• Grooves on the metal.

It is necessary to replace the valve or transmission with the engine running if the manifold is too worn or burnt out.

Adjusting the speed is necessary if the wipers are running too slowly. This contributes to:

• Incorrect (too “dense”) lubrication;
• Gear wear;
• Traction deformation.

Eliminating these problems basically makes the wipers work faster and, in addition, significantly.
