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.

VAZ 2107 washer does not work reasons, repair

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!

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.

Windshield washer pump VAZ 2107

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.

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.

Why does the windshield washer not work?

To determine why the windshield washer on the seven stopped working, it is necessary to carry out a thorough diagnosis. To help you carry out self-diagnosis, use the diagram shown in the photo above. Once a faulty element is detected, it will need to be repaired or replaced, depending on the nature of the failure. Malfunctions of the element in question can be divided into minor (you can fix it yourself) and serious, requiring replacement of the faulty part. Let's take a closer look at the main components of the system and their malfunctions.

Where does which wire go, or just a diagram

Connecting wipers and washer

“Plus” power is supplied from the ignition switch through fuse No. 2 at 10 Amp of the mounting block. The permanent “plus” goes along the black and yellow wires to contacts “4” of the connectors of the gear motor and the steering column switch. It should not disappear even when the switch is in the “off” position. The blue wire supplies “+” 12 V power to the motor when the switch is in “continuous mode” position. On the blue-white wire, in the “off” position there should be a “minus”, and in the “continuous mode on” position the “minus” is turned off. This is done to slow down the motor when the power to the closer is turned off.

The red wire supplies the relay with “+” 12 V from the switch when the intermittent mode is turned on. At the moment of operation, contacts “2” and “4” close, and “1” and “3” open, the motor starts working and the brushes make one or two movements. Then “+” 12 V is turned off, and contacts “1” and “3” are closed to each other and to “minus”. The motor stops for a few seconds and then the cycle repeats.

VAZ 2107 wiper malfunctions

Replacing a burnt out motor

During the winter season, at sub-zero temperatures, wipers often stick to the windshield. The wiper motor is under a lot of load, and it burns out if the bimetallic fuse does not work or the fuse burns out.

Location of the glass cleaner and washer fuse in the mounting block

In such cases, it is necessary to replace the motor. To do this, you need to remove all the parts in a certain order:

• Unscrew the fastening nuts;
• bend the lever and remove it from its seat;
• Using a 22mm wrench, unscrew the trapezoid fastenings on both sides;
• remove the plastic inserts;
• remove the hood seal;
• remove power from the windshield wiper motor;
• remove it with the drive from the hole in the body;
• bend the protective cover, unscrew the fastening nuts;
• press on the protrusions of the slots on the reverse side, on which the wiper arms sit, so that they fall inward, move in different directions, the trapezoid with the motor will come out.

Video instructions for replacing the windshield wiper trapezoid

After disconnecting the mechanism parts, you can repair the gear or install a new motor. But the electric motor must be inspected, even if it is in working condition. It is a conventional DC electric motor, the rotation of which, through a worm gearbox, is supplied to a trapezoid.

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.

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.

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!

Wipers VAZ 2107

The vehicle is operated in different climatic and road conditions. For safe and comfortable movement, the driver must have good visibility of the road situation, i.e. the windshield must always be clean. Windshield wipers provide mechanical cleaning of the windshield from dirt and sediment, improving visibility and increasing safety. We will consider possible problems with this mechanism and ways to eliminate them in more detail.

Principle of operation

The work of the wipers is quite simple and consists of the following sequence of actions:

1. The driver selects the desired operating mode of the windshield wipers using the steering column switch.
2. The entire windshield cleaning mechanism is driven by a motor.
3. The wipers move across the glass left and right at the selected speed, cleaning the surface.
4. When the mechanism is no longer needed, the steering column switch returns to its original position.

Components

The windshield wiper consists of the following main elements:

• lever mechanism (trapezoid);
• electric motor;
• relay;
• brushes

Trapezoid

One of the important elements in the windshield wiper mechanism is the trapezoid. On almost all cars this part is the same, and the difference lies only in the methods of fastening, the size and shape of the elements. The functioning of the trapezoid consists of transmitting rotational motion from the electric motor to the wipers, as well as ensuring the synchronous movement of the latter for high-quality glass cleaning. The trapezoid consists of rods, a body and a hinge.

Trapezoid design: 1 - crank; 2 - short thrust; 3 — joint of rods; 4 — rollers of the windshield wiper mechanism; 5 - long pull

Motor

The electric motor of the windshield wipers of the VAZ “Seven” is made as a single unit with a gearbox and is one of the main links of the mechanism in question. The motor consists of a stator with permanent magnets and an armature with an elongated shaft, at the end of which a screw is threaded. The purpose of this unit is to ensure the movement of the blades along the windshield. The device is considered reliable and fails very rarely.

Wiper relay

On classic Zhiguli cars, the windshield wiper has two operating modes - fast and intermittent with an interval of 4-6 seconds. It is to ensure intermittent operation that the RS 514 breaker relay is designed. Delayed activation of the wipers is used during light rain, when too frequent operation of the windshield wipers is not required, and when the mechanism is completely turned off, the glass is gradually covered with small drops of precipitation and needs to be cleaned. The product is connected to the general wiring using a four-pin connector. On the VAZ 2107, the breaker relay is located on the driver’s side on the left side panel under the plastic trim.

The wiper relay ensures intermittent operation of the mechanism

Brushes

Almost all passenger cars use two windshield wiper blades. On the “seven”, elements with a length of 33 cm are installed from the factory. Longer brushes can be installed, but a greater load will be placed on the electric motor, which will lead not only to slower operation of the mechanism, but also to possible failure of the motor.

The VAZ 2107 is equipped with brushes 33 cm long from the factory.

We disassemble the turn switch for a VAZ 2107

And although many manufacturers of turn switches claim that this is a completely non-separable design, it can still be disassembled with some effort. Disassembly of devices is necessary when repairing it. It takes place in several stages:

1. Using a 3 mm drill, drill out the 2 upper rivets and remove the upper part that is attached to the tube;
2. After removing this part we see 2 more rivets that hold the ring;
3. Carefully remove the ring from the grooves, then you need to remove additional rings and levers.

Mechanical breakdowns

The most common reasons why the VAZ 2114 windshield washer does not work are mechanical damage.

The most common of them are:

1. the washer fluid has run out in the tank;
2. the pipeline leading to the windshield wiper is clogged;
3. the windshield wiper nozzles are clogged;
4. the water used as washer fluid froze;
5. the hose fell off the pump;
6. the hose going to the windshield wiper is pinched;
7. The supply hose has ruptured.

We repair the device

In the VAZ-2107, the switches are located under the steering wheel of the car. If you suspect a malfunction, the first thing you need to do is find out the reason why this or that function does not work.

Repairing the switch

We remove the steering column switch on the seven. Having removed the first ring, then the headlight, stop and wiper levers, we get to the mechanism by which the turns are automatically turned off. We take it out and here lies the cause of all the troubles: between the reeds there is a spring that breaks off and does not move the reeds in different directions. It is necessary to replace the spring; you can use a regular spring from a ballpoint pen. Next, we begin collecting all the rings and levers in reverse order. After finishing the work, we check how the levers and the turning mechanism work. To do this, we connect the pads and place the terminals on the battery; if all functions work, then we have completed the repair.

Electric motor for windshield wiper VAZ 2107, diagram

The VAZ 2107 car is equipped with an electric windshield wiper motor (wipers), which can clean it in intermittent and continuous modes.

Here is a diagram of its connection with a description of its features and operating procedure, which can help if any malfunction occurs with it.

Connection diagram for the electric motor of the windshield wiper (windshield wipers) of the VAZ 2107 car

Description of the connection diagram for the electric motor of the windshield wiper VAZ 2107

— Voltage in the electrical circuit for switching on the windshield wiper motor is supplied from the positive terminal of the battery through terminal “30” of the generator and the ignition switch. That is, you can turn on the wipers only after turning the key in the lock.

— The electrical circuit is protected by fuse F2 (10A) in the mounting block.

— The electric motor of the wiper is turned on using the lever of the right steering column switch: the first position is intermittent mode of the wipers, the second position is the brushes work constantly.

— When the intermittent operation mode of the wipers is turned on, electric current flows through the breaker relay RS-514. There it goes from the steering column switch through the red wire to the relay electromagnet and its thermobimetallic breaker and then through the gray wire to the wiper motor.

When current passes, the relay breaker plate heats up, bends and opens the breaker contacts. In this case, the contact of the electric motor switch is closed to ground (yellow wire from the steering column switch to the relay and blue-white wire from the relay to the electric motor). The electric motor stops. After which the breaker plate cools down, straightens and again closes the contacts inside the relay, the voltage is again supplied to the electric motor. He starts working. Such on and off cycles are repeated with a frequency of 9-17 times per minute.

Notes and additions

— On a VAZ 2107 car and its modifications of different years of production, as well as on VAZ 2104, 2105 cars, the color of the wires in the windshield electric motor connection diagram may differ from the one shown above.

— In addition to the windshield cleaner, the VAZ 2107 has a washer, consisting of an electric motor for a pump in the washer fluid reservoir, pipes and spray nozzles. It is turned on by the same right steering column lever (move it towards you to an unfixed position). Here is its connection diagram “Windshield washer connection diagram for a VAZ 2107 car.”

Malfunctions of the VAZ 2107 windshield washer - causes and repairs

One of the important parts of each car is the glass cleaning mechanism, which is presented in the form of wipers and washer. Sometimes a situation arises when the VAZ 2107 windshield washer, which is designed to clean the glass from dirt, does not work. With its help, water or a special liquid is sprayed, through which dirt is removed along with the wipers. We will consider in detail how to diagnose a mechanism malfunction, as well as eliminate the breakdown.

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.

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.

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.

Windshield washer VAZ

The first VAZ models 2101 and 2102 were equipped with a windshield washer system, in which the electric pump was activated via a foot switch. On later models, for example, VAZ-21011 (21013), the pump was turned on using a lever on the steering wheel. This scheme is used today on almost all modern cars.

Structurally, the VAZ-2101 (2102) washer circuit includes the following elements:

• jet-type jets (nozzles);
• a tee that distributes liquid into two streams for the left and right nozzles;
• electric pump with switch;
• tank;
• pipelines (hoses).

Note : The electric windshield washer pump of the VAZ-2101 is made according to a non-disassembling design. If it fails, repairs are not performed. Therefore, the only way in this case to restore functionality is to replace the faulty pump with a new device.

Injectors VAZ-2101

The VAZ-2101 jet nozzle is made in the form of a cylinder with a calibrated channel inside. The liquid entering the housing is sprayed through a nozzle (spray) onto the glazing surface. At the bottom of the nozzle body there is a fitting for connecting the fluid supply hose. A sprayer with an adjusting screw is mounted in the upper part at an angle of 90 degrees to the axis of the nozzle. A plastic sleeve is placed on the middle part of the body for fixation in a special hole on the hood.

Windshield washer pump VAZ-21011 (21013)

The design of the washer system pump follows a very simple design. If necessary, you can easily cope with its disassembly and repair.

The pump is a hollow cylinder, inside of which a shaft with a rotor is mounted on a coupling. A shaft support is mounted at the bottom of the pump. A mesh filter is attached to it. An electric pump is bolted to the washer pump housing from above through the reservoir cap. A fluid supply hose is connected to the bottom of the housing. Its second end is connected to the fitting in the tank lid. Thus, the electric drive pump and the tank lid are combined into a single structure.

Why does the washer not work well?

There can be several reasons why the windshield washer fails:

• system clogging;
• clogged injectors;
• freezing of liquid;
• failure of the electric motor;
• pump failure.

System clogged

If debris gets into the tank, the system hoses may become clogged; in this case, liquid will not flow to the nozzles. To eliminate this problem, you need to rinse the tank and fill it with clean liquid.

Clogged injectors

The calibration hole of the washer jets has a very small cross-section. If debris gets in, the nozzle becomes clogged and does not allow liquid to pass through. In this case, it is necessary to remove the injectors, disassemble and clean them. The nozzles can be cleaned by blowing with compressed air without dismantling. However, you should first disconnect the fluid supply hose to prevent debris from entering the system.

Dismantling . To remove the nozzle, you must first disconnect the fluid supply hose. Then you should squeeze the plastic sleeve from below (from the side of the air intake system box). Then pry the bushing from above with a flat-head screwdriver and pull out the nozzle along with the bushing.

Note : The injector can also be pushed up by gently pressing the inlet fitting from below, after opening the hood.

disassembled in the following order:

• unscrew the adjusting screw installed in the sprayer;
• thoroughly clean and rinse all parts of the nozzle;
• we blow through the cavity of the body and the nozzle sprayer with compressed air;
• Assemble the nozzle in reverse order.

Note : When cleaning jets with metal objects (needle, pin, thin wire), do not be too zealous so as not to damage the calibration hole.

Installation . First, insert the plastic sleeve into the hole on the hood. We take the nozzle by the upper part and push it into the bushing hole until it stops. After this, connect the fluid supply hose to the fitting.

Troubleshooting equipment

A failed washer that does not blow the windshield with a special liquid is restored. Most often, the injection pump needs to be replaced, 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 place we insert a new unit into the tank.
4. We put connectors on the contact group, after which you can perform the test.

The engine operates with a characteristic 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 little time for them to fill with liquid. Using this system as intended will allow you to drive in any weather.

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.

Replacement

If the old motor has failed, there is no point in trying to repair it somehow. To buy a new part, you will have to spend very little money. And the replacement procedure on most cars is extremely simple.

I will describe the main stages of work associated with replacing this element of the windshield cleaning system of any car.

• Turning off the vehicle's power. A safety measure without which further work makes no sense. Be sure to remove the negative terminal from the car. It's simple but important. Otherwise, you not only risk burning the wiring, but also getting an unpleasant electric shock yourself.
• Search for a motor. It all starts with identifying where your windshield wiper motor is located. It depends on your car. On some cars, just lift the hood and you will immediately see the washer reservoir. The motor itself is located on the reservoir (partially inside) of the windshield wiper, into which the liquid is poured. Do you see the tank? If yes, then you are in luck. If not, then you will have to look for it by removing elements of the engine compartment. On some car models, the tank is hidden so that the fender protection has to be removed.

• Disconnect the connectors with wires from the motor. Then remove the tank itself.
• The hose and fitting are separated from each other. Don't forget to drain the liquid. Filling a new one will not be difficult. Yes, and for prevention it won’t hurt to do it.
• Using a screwdriver, push the intake seal out of the bushing. This will allow you to completely remove the windshield washer motor.
• Don't forget to install a new bushing when reassembling. This often leads to the washer pump itself breaking down. So the old bushing goes to the landfill.
