Electric motor for windshield wiper VAZ 2107, diagram

Cars have special equipment for travel during bad weather associated with precipitation. The windshield of the VAZ 2107 is cleaned of water using movable brushes, and in case of contamination, the washer is activated. This device sprays a special liquid, it works simultaneously with the windshield wipers and removes dirt.

The equipment thus provides the necessary visibility for the driver and passengers. This device includes the following elements:

1. Liquid reservoir.
2. A pump that runs from the on-board network.
3. Nozzles that blow a water jet onto the windshield of a car.
4. Tubes connecting the tank to the actuators.

At the end of the summer season, the water in the system is replaced with non-freezing liquid, which will allow the system to be used in winter.

Main causes of failures of additional equipment

If the washer on the car does not work, it is necessary to diagnose it using simple techniques. This system may fail for a number of reasons, which are listed below:

1. breakdown of the injection pump;
2. fuse blown;
3. kinking or squeezing of the supply hose;
4. breakdown of the steering column switch;
5. freezing of water in pipelines or other devices;
6. loss of contact in the electrical network.

It is possible to determine the cause of the malfunction and the amount of costs to restore the system's functionality based on the results of a careful inspection. If you need to replace individual parts or elements, you can do it yourself. The device that blows the windshield to clean it from fresh or dried dirt does not work.

Most likely, you will need to replace failed equipment.

Cause of failure due to electrical

Electrical causes may be:

• The fuse may have blown. It is located in the fuse box;
• Check the leads that are equipped with the VAZ 2110 washer motor; it is quite possible that they have oxidized. It happens that the terminals completely fall off;
• The windshield washer switch located on the steering wheel does not work. Its performance can be easily checked with a multimeter;
• Wiring faulty. The wires may need to be replaced;
• The windshield washer relay does not work. The best treatment is also replacement.

Operating principle

On a VAZ 2107 car, the wipers are driven by a 12 V electric motor. A relay is installed in the windshield wiper activation circuit. It is responsible for the intermittent operation of the wipers, which work without interruption or at intervals of four seconds.

The windshield wiper is connected in parallel through the contacts of the closer. They are located in the gearbox housing and are “responsible” for returning the brushes to their original position and abruptly stopping the motor. The driver controls the operating mode of the windshield wiper using the switch. The whole mechanism works thanks to a motor. It is prohibited to operate a car with faulty wipers, so car owners must ensure that they are in good working order. And in bad weather, driving with non-working wipers is very dangerous!

How to install washing machine attachments

Nozzles for washing machines of any type can be adjusted. They are a plastic housing in which several nozzles are installed (usually 2 or 3). These attachments are spherical in shape and can be adjusted by the driver as desired. To adjust the nozzle nozzle for the washer

, it is enough to have a simple needle with which you can gently turn them in the desired direction.

If the car is equipped with three-jet injectors, there is no need to install them at the same height. It is advisable that the outermost windshield washer nozzles be directed to the lowest points. This will protect the glass from micro-scratches (which can happen if the windshield wipers are “dried out”), and the sprayed liquid will not interfere with the driver’s vision. The central washer jet should be adjusted so that it touches the top of the glass.

On each specific car, the driver must decide for himself how convenient it is to control the windshield nozzles. Don't neglect their settings, you just need to spend a couple of minutes to avoid visibility problems while driving when cleaning your windshield.

The cars have special equipment for driving in bad weather. The windshield of the VAZ 2107 is cleaned of water by movable brushes, and if dirty, the washer

. This device sprays a special liquid, it works simultaneously with the wipers and removes dirt.

Thus, the equipment provides the necessary visibility for the driver and passengers. This device includes the following elements:

1. Liquid tank.
2. The pump is running on board.
3. Injectors that perform the windshield of a car.
4. Pipes connecting the tank to the drives.

At the end of the summer season, the system replaces the water with an antifreeze liquid, allowing you to use the system in winter.

Possible windshield wiper malfunctions

The main types of malfunctions include the following reasons:

• the switch has failed, which happens in frequent cases;
• the fuse has blown, which could have happened as a result of an overload of the electric motor, water getting on it or overheating of the wiring;
• poor circuit contact or lack thereof;
• windshield wiper motor malfunction;
• breakdown of the VAZ 2107 windshield wiper relay.

If the breakdown consists of a blown fuse, then replacing it will not be enough; it is also necessary to find the true cause of such consequences. Next, we will consider the main types of wiper malfunctions on the VAZ-2107 with a detailed description of their solutions.

The electric motor of the cleaner does not function

If the electric motor does not work, but there is voltage at its contacts, then the problem is in the device itself. This could be wear on the brushes or failure of the windings. The brushes wear out over time, and the winding fails when the motor is overloaded. These products can be repaired, but for this you need to contact a workshop.

Elimination of equipment defects

A failed washer that does not blow the windshield with a special liquid is restored. Most often, it is necessary to replace the injection pump, which occurs in the following sequence:

1. The contact group is removed from the device.
2. Using a short screwdriver, remove the compressor from the hole.
3. In its space we insert a new unit into the tank.
4. We put connectors on the contact group, after which you can check.

The engine operates with an appropriate sound when functioning correctly. The glass is blown with a water jet from the nozzles. If the tubes are replaced, you will have to wait a short time to fill them with liquid. Using this system as intended will allow you to drive in any weather.

The most common windshield wiper failures

If the wipers on your car suddenly stop working, the cause of the problem can be identified by focusing on the following symptoms:

1. The gearbox operates normally, but the wiper blades do not move. Most likely, the problem lies in worn or broken gear teeth that need to be replaced. Also, sometimes it is enough to tighten the nut holding the special crank mechanism located on the gear to solve the problem.
2. The wipers don't work at all. In this situation, it is necessary to check the serviceability of the fuse, and if a breakdown is detected, replace the part. In addition, we recommend making sure that the fuse contacts have not oxidized due to exposure to moisture.
3. The wiper blades do not work intermittently. The most common problem is with the relay, so diagnosing this device first is required.
4. After turning off, the wipers do not return to the first position, but freeze in an arbitrary position, sometimes blocking the driver’s view. This problem is associated with a gearbox failure. It is quite repairable, but sometimes replacement may still be required.
5. When the windshield wiper is turned on, the motor does not click and shows no signs of life. This problem occurs due to burnout of the winding or contamination of the contacts. In any case, you need to check the electric motor.

In addition, the windshield wiper may fail due to a malfunctioning switch located, as mentioned earlier, on the steering column.

It can be easily replaced, since this part is inexpensive and easy to install.

System diagnostics

A running washing machine sprays a stream of water onto the windshield and the brush moves at the same time. You can determine which element needs to be replaced as follows:

1. Start the engine and open the hood.
2. We ask an assistant to pull the steering column control lever towards himself.
3. If the pump is running, it will be clearly audible.
4. There is no flow of water around. this means the injectors are clogged.

If the fluid in the tank is frozen and requires replacement, it is difficult not to notice such a malfunction.

System diagnostics

To understand the reasons for the inoperability of the windshield washer on the VAZ 2107, you should first of all consider the design of the system. It consists of the following elements:

1. Washer fluid reservoir.
2. A pump with an electric motor, which operates from a 12V network.
3. Nozzles or sprayers of a water jet that hits the windshield.
4. PVC pipes connecting the above elements.

A special liquid is poured into the washer reservoir, one type in summer and another in winter. Winter liquid is called “anti-freeze”, with its help you can effectively wash windows at sub-zero air temperatures, and not worry about the fact that it may freeze in the system.

When the washer is turned on, liquid is sprayed onto the windshield with the simultaneous automatic activation of the wipers. If, when you turn on the device, there are no signs of its performance, then you can determine the cause of the breakdown yourself. The electrical diagram for connecting the washer on a VAZ 2107 is presented below, based on which you can sort out the malfunctions.

How and what to fill in the washer reservoir?

Above we looked at how to remove the washer reservoir, check the system sensor and change the container (if it is damaged). But there are situations when the container body is intact, and the only thing that needs to be done is to add liquid.

In such a situation, proceed as follows:

• Pull the hood handle located in the cabin.
• Open and secure the hood.
• Unscrew the cap that is installed on the tank. In this case, unscrew only the cover that does not have wires.
• Add liquid (water or anti-freeze). If the container is empty, it holds about five liters.

Why doesn't the windshield washer work?

The system for cleaning glass and car headlights includes: a liquid reservoir, a pump, nozzles, tubes, electrical wiring and a power button. Most often, the reason why the windshield washer does not work is a faulty motor or a blown fuse. The operating principle of a windshield washer is quite archaic, so simple diagnostics and simple repairs can be performed almost at the doorstep of the nearest auto parts store.

Malfunctions and operating principles of hand and foot-operated windshield washers, which were installed on some VAZ and AZLK models, deserve a separate topic and will not be discussed in this article.

Causes of failure

• The windshield washer pump fuse has blown. Manufacturers mark consumers who are protected by fuse links with graphic symbols on the inside of the relay and fuse box cover. If the markings are unclear or the required insert is not marked, a detailed fuse location diagram can be found in the repair and operating manual for your car. Attention! Installing a larger fuse may cause the vehicle to catch fire. If the new fuse-link burns out immediately after installation, there is a short circuit in the circuit.
• The windshield washer motor is burnt out or soured. The low cost of the pump makes its disassembly and repair impractical, so simply replace it with a new one.
• The contacts on the connectors have oxidized, the power wires have become frayed or broken. In field conditions, oxides can be removed from the terminals with a sharp object. At the same time, do not damage or bend the terminals so as not to disrupt the quality of contact in the connector.
• The coarse filter in front of the windshield washer pump is clogged (not installed on all cars). The filter is attached to an O-ring that seals the pump installation location. If trouble catches you on the road and you cannot clean the filter element, temporarily remove it from the line.
• The hose from the pump to the injectors has fallen off or broken.
• The injectors are clogged. In winter, injectors can become clogged not only with debris and plaque, but also with ice. After using the windshield wiper, a washer fluid remains on the nozzles, from which the alcohol evaporates over time. The water remaining near the nozzle freezes, which is why the windshield washer does not work. You can pierce the injectors with a thin needle.
• The fluid in the washer reservoir has frozen.
