The wipers of the VAZ 2110 injector 8 valves do not work reasons

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.

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.

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.

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.

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.

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.

Wipers do not work on VAZ 2110: causes and solution to the problem

If one fine morning the wipers on a VAZ 2110 fail to work, the causes of this malfunction should be established. To do this, you need to get to the windshield wiper device.

The VAZ 2110 has three operating modes:

Owners of the VAZ Ten probably encounter noise and crackling noise when they turn on the wipers; this is often due to a malfunction of the electric motor.

Wipers are one of the most vulnerable systems in a car. The windshield wiper system has to work, for example, in severe frosts. In this case, you should check whether the blades freeze to the windshield, otherwise the electric motor may burn out.

If the electric motor of the engine does not show signs of life, the problem may lie not in it, but, for example, in the blown fuse F5 in the mounting block. It is located on the left side of the car, under the headlight control. If the fuse turns out to be fully operational, the problem lies in the power supply to the wiper motor. It is necessary to check the electrical circuit that connects the gear motor, fuse, steering column lever and the switch itself. A multimeter will help determine which part of this circuit there is a malfunction. If the monitor shows “zero”, the area is working properly. You see an infinitely large series of numbers on the screen - this is a reason to check all the terminals and wires.

The problem with poor current supply is solved as follows:

• Clean and crimp the terminals in each block;
• Completely change all wires;
• Change the wiper switch lever.

In the first two positions, the K2 relay type 524.3747 in the mounting block and the steering column switch itself are responsible for the intermittent operation of the wipers. If the wipers work properly in the third position, you should pay attention to the relay. If the relay is faulty, the wipers can operate in intermittent modes without complaints, but there will be no characteristic pauses when switching.

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.

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, 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 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.
