Priora wiper motor does not work

Why do wipers fail?

There can be many reasons why windshield wipers fail. Most often, wipers break due to electrical overloads, as well as when the mechanism jams.

In winter, wipers can fail due to a large accumulation of precipitation on the windshield or freezing to the glass. It is highly not recommended to turn on the wipers until the car's windshield has warmed up.

Windshield wiper failure can occur for quite trivial reasons:

fuse F5 burned out;
the terminals of the connecting blocks are oxidized or burnt;
wires are faulty;
relay K5 524.3747 broke;
ordered the steering column switch to “live for a long time”;
the nut that attracts the trapezoid crank to the gearbox has become loose;
the nuts securing the levers to the trapezoid shafts were unscrewed;
The brushes are frozen to the glass.

Often, wipers on models of the VAZ 2110 family do not work due to complex faults:

oxidation/burning, insufficient pressing force of the contacts of the limit switch located on the gearbox cover;
brushes hanging in the gearmotor;
burnout/contamination of the collector;
break in the armature winding;
chipping of gear teeth in the gearbox.

VAZ 2109 wipers: examination and rehabilitation techniques

The “nine” has a classic windshield wiper circuit: the steering column switch via a relay (intermittent modes) or directly supplies power to the electric motor, which causes the gearbox – crank – trapezoid – brush holders to rotate. Long-term practice demonstrates that

Determining the causes of a windshield wiper malfunction on a VAZ car

wipers If suddenly the wipers on your car stop working, this is not a reason to panic. This device is quite simple and, if desired, anyone can independently eliminate the cause of the malfunction by following the further instructions. And so, let's find out why the wipers on your VAZ-2105 do not work.

How to detect and fix problems in the windshield wiper system of a Lada Kalina car

The design of the windshield wiper system is a fairly simple diagram. If desired, any car owner is able to understand the cause of the malfunction and fix it independently.

Types of wiper breakdowns

Windshield wiper failures can be divided into two types: electrical and mechanical. Each type of breakdown is complex in its own way and makes it difficult to repair in the field. In some cases, it is necessary to remove many parts to get to the source of the problem.

The most common wiper failures:

Fuse blown;
Windshield wiper motor winding burnout;
Wiper switch malfunction;
Burnt out wiper relay;
Breakdown of wiper splines;
Mechanism failure or jamming;
Gearbox jamming;

Why don't the wipers work on the Priora?

If the windshield wipers fail on your Lada Priora, you must initially follow the instructions below.

If the wipers do not work in cold weather after starting the car, you need to check them to see if they are frozen to the windshield. This happens after the car has been idle overnight, and if there was precipitation at night, this may be the reason.

Blowing a fuse happens very often; if you drive a car in the rain and turn on the wipers at maximum speed, the current in the power circuit will increase, which can lead to a blown fuse. It is necessary to check the fuse in the mounting block numbered F11. If the fuse is faulty, it must be replaced with a new one with a rated current of 10A, and in hatchback and station wagon bodies 20A.

Then you need to check the relay, and this is done like this. We turn on the wipers and place our finger on the relay number K6, it should make a characteristic click. If this does not happen, change the relay.

Checking the steering column switches. This can be done by transferring them from another similar car.

Oxidation of contacts on the wiper motor. Since the engine is located under the frill, moisture can sometimes get there and cause oxidation of the contacts. To do this, you need to dismantle the wipers and frill, and then clean the contacts on the electric motor.

Checking the engine for integrity. This can be done by applying a voltage of 12V to the motor contacts. A working motor should start to rotate.

After disassembling the frill, it is necessary to inspect the mechanism for rust and corrosion. It is possible that the entire mechanism is jammed due to rust formation.

By following these instructions, you can easily repair the wipers yourself.

parking lights

For example, the electrical circuit of a Lada Priora station wagon has the function of both automatic and manual activation of side lights. The activation itself occurs after turning the handle for the side lights and headlights on the dashboard. The contact is triggered and the lights turn on.

The circuit contains fuses that serve to protect against overvoltages and short circuits. Power is supplied to a lamp located on the dashboard. To adjust the brightness of the lights, a special regulator located on the lighting control module is used.

The headlight design of the Priora differs from other cars. The electrical circuit of the VAZ Priora contains a light sensor, as well as a lighting control unit. After turning on the ignition and the lighting control button, the electronic unit responsible for lighting control is activated.

If there is not enough light outside, the unit receives a signal from a sensor located on the windshield. There is also a rain sensor there. After receiving such a signal, the electronic control unit supplies power to the electromagnetic relay coil. Power is supplied to the headlights.

Wipers on Lada Priora do not work: reasons and how to fix it?

Before going to the inspection, I discovered that the rear window wiper was not working. There is no noise and there is no movement of the wiper either, but the motor should work.

It is clear that since the rear window washer does not work, then three reasons may be to blame:

Fuse
Shift lever
wiper motor

Since a new motor is not cheap, I decided to tinker with its repair myself.

First I checked the fuse. It turned out to be without damage or soot. Then I decided to check the steering column switch. Since all its other functions worked, except for turning on the rear wiper itself, I decided that it was working. It's time for the motor itself.

Do-it-yourself troubleshooting

The main reasons for the lack of washer fluid can be eliminated with your own hands.

Cleaning the injectors

Their replacement and cleaning occurs in the same way and it begins with the removal of these parts, the process is as follows:

open the hood;
make sure that they have plastic plugs; if they are present, they must be carefully removed;
take a flat-head screwdriver and open their spring fasteners to remove the injectors.

Installation of new parts occurs in the reverse order.

To wash the injectors and free them from dirt, you should prepare a special cleaning solution of non-chlorinated water and vinegar, taken in equal proportions. The mixture is mixed well and then poured into the tank. After which you need to press the washer lever, even if the water does not reach the glass, it’s okay. So that the components of the solution have time to break down all the contaminants, you need to leave it in the cleaning system for 2 hours, and then press the lever again. After the dirty solution flows out of the nozzles, rinse the hoses with distilled water.

Replacing the motor

It is quite difficult to repair the motor yourself, so most often it is simply replaced.

Installation of a new device is carried out as follows:

remove all liquid remaining in the tank from the tank;
disconnect the contact between the battery and the pump;
if necessary, you can dismantle the tank, but if manipulations can be carried out with a fixed device, then you don’t have to do this;
remove the electric pump from the tank and unscrew all the hoses going to it, but just remember their location so that after repair they can all be returned to the correct places;
connect a new pump to the system;
screw all the tubes;
connect the battery to the motor;
pour liquid into the reservoir.

Check the operation of the motor by pressing the washer lever; if you hear a whirring sound from the pump, then everything went well.

Removing and disassembling the windshield wiper motor

All the important parts of the rear windshield wiper are located under the trim. To remove it, I had to tinker, since it was attached to special holders, which are not so easy to remove without special tools. Fortunately, I had a nail puller at hand and it was perfect for removing these fasteners.

After unscrewing the rear wiper mount, I unscrewed the mount of the motor itself. I disconnected it from the block and took it home for inspection.

There appears to be no damage. Then he unscrewed the mount of the motor housing and pulled the structure out of it. The mechanism itself is covered in lubricant; there was plenty of it.

I looked at the gears, they were intact. Next, I examined the wires attached to the microcircuit. They had a raid. I thought this was probably the reason and decided to move them a little (in a good way, it would be better to resolder them), the “dust” flew off.

That’s it, there’s nothing more to look at, I put the mechanism back together and went to connect the motor to the wiring block to see if it works or not.

I turn on the ignition and rear window wiper. That's it, the rear wiper is working. Hooray! I screwed everything into place and went for inspection.

Replacing the windshield washer reservoir

If suddenly for some reason there is a need to replace the tank, it is very easy to do it yourself. No special skills or tools are required here. All work can be done with almost bare hands.

Before removing the windshield washer reservoir, be sure to disconnect the hose and power cables from the motor and level sensor. Then use a 10mm socket to remove the bolts that secure the reservoir to the slots. Now this part will come off easily if you pull it up.

Don't forget to remove the electric pumps from the tank. The sealing sleeve can be easily pryed with a screwdriver and removed from its seat. If this part is no longer flexible or has any damage, it should be replaced.

After this, you need to remove the level sensor from the tank. To do this, you must unscrew the plug and remove the sensor. Now all work is completely finished.

What to do if the wipers on a Priora are slow

The performance of wipers depends on many factors. How to check the performance of windshield wipers? An aspect of proper operation is the ratio of timing to the number of strokes of the wiper blades.

If the principle of operation of the device is not violated, then the number of progressive double strokes must be at least 35, which, in turn, is prescribed in the rules of traffic malfunctions. If the wipers work slowly on a Priora, it is necessary to diagnose and eliminate the corresponding malfunction.

Improper use of windshield wipers in winter is one of the reasons for slow operation
A common cause of the windshield wipers working slowly on a Priora may be a malfunction of the motor, and in particular the brushes located in it.

There are quite a few reasons for this malfunction, but it is the incorrect use of windshield wipers in winter that can burn the blades. This happens as a result of strong resistance, namely when the windshield wipers are frozen to the windshield.

The situation with the intensity of wiper operation improves as the car engine warms up. If the cause of the breakdown is related precisely to this, then, regardless of the active operating position, the windshield wipers (1st or 2nd) will slowly creep up. In the opposite direction (backward) - a little faster. A problem of this kind can only be solved by replacing the device.

Freezing of devices

The problem of brush failure in winter is quite common. Often car enthusiasts start looking for a cat in a dark room, disassembling the system and trying to find a breakdown where there is none. In fact, the reason may lie in elementary things, namely freezing. This often happens in the following cases:

when the car is left in the open air after using water wipers;
when the car ends up in an unheated garage.

Therefore, before disassembling, first try to find out if everything is normal with your brushes. Are they frozen to the windshield or rear window? Folding up the wipers after parking the car will help prevent this.

Priora windshield wiper does not work

Failure of the windshield wiper Priora is expressed, as on other machines, in the absence of any operating mode, completely inoperable or constant operation of the windshield wiper at the zero position of the switch.

Priora's windshield wiper does not work in all positions

Consider the moment when the windshield wiper does not work in any position. First of all, you need to check the integrity of fuse F11. It is located in the relay and fuse box inside the car under the driver's side panel.

It is better to check the integrity with a test lamp, this will allow you to find out whether there is power on it or not. If the fuse is faulty, it must be replaced. If there is no power on it, then you need to check the activation of the ignition switch unloading relay K4. To check it, just replace it with any nearby one.

To check, you can use any universal relay located in the same block.

If the fuse is working properly, you need to check the power supply. If there is no power, then you need to remove the connector from the windshield wiper switch and check for the presence of a positive signal at terminal 53a with the ignition on. If there is power, connect connector pins 53a and 53 or 53a and 53b with a piece of copper wire.

In this case, the windshield wiper should start working at low or high frequency. If this does not happen, then, without removing the jumpers, check for the presence of a positive on terminals 1 or 2 of the windshield wiper connector. If there is no power, then you need to find an open circuit.

The most likely location is the connector connecting the instrument panel wiring harness and the front wiring harness.

If there is power, check pin 5 of the windshield wiper connector with a test lamp. A dim glow of the lamp indicates poor or absent contact in the negative wire and the car body. If the circuits are working properly, the electric motor of the windshield wiper gearmotor or the thermal fuse is faulty.

The fuse protects the motor from overheating due to freezing of brushes or other jamming of drives. It is located under the gearbox cover and requires replacement if it malfunctions. The circuit is also checked when the wiper does not operate at low or high speed.

Priora's windshield wiper does not work in intermittent mode

If the windshield wiper does not operate intermittently, then first of all you need to check the condition of fuses F20, F22 and F23. Defective fuses should be replaced. If the fuses blow again, do not install jumpers (bugs) in their place.

Installing a jumper may result in a fire. First of all, it is necessary to eliminate the short to ground in the wire protected by this fuse. When searching for a short circuit, pay attention to the places where the wires contact the body.

At places passing through walls where there is a possibility of damage to the insulation, as well as turning on relay K12. If the relay does not turn on, then swap it with relay K6 and repeat the test.

If the relay also does not turn on, check the integrity of the wire connecting terminal 88 of the relay and fuse block with terminal 8 of the automatic windshield wiper and lighting control unit.

If the wire is OK, check the power at terminals 3, 9 and 20 of the windshield wiper control unit with the ignition on. If not, eliminate the fault; if present, replace or repair the control unit.

If K12 closes when you turn on the intermittent mode, then remove the relay from the socket and bridge pins 87 and 30 in the socket with a copper wire. Remove relay K6 from the socket and check with a test lamp the presence of power at pin 30 of the socket. If not, repair the broken wire or poor contact in the connecting wire.

Mechanical reasons

Wipers can break at any time of the year. For example, it may not work well in the 3rd position of the switch or not respond at all to certain modes.

In this case, the reasons may lie in the electrics, so carefully study the electrical circuit of the car and the connection of the wipers in particular. Let's look at the main symptoms of problems and find out what leads to this.

When you turn on any mode, there is no click from the thermobimetallic fuse. If there is no response to your attempts to turn on the wipers, fuses F11 or F20 may have failed. You also need to make sure that the contacts have not been oxidized.
If a click is heard, but there is no reaction, it means that the electrics are working properly, but the problem is with the mechanics. Here we return to the previous problem with brushes freezing. Alternative options are skewed drive rods or a wedge of gears.
Intermittent movement of brushes. The problem lies in relay K6 or K12. Simply replacing it is enough. Using the control unit, you can set the necessary program for relay K6.
If the wipers do not go to the first position, there may be a program failure in the control unit or it has completely failed.
If the engine of the device is running, the wipers twitch, but do not move completely, you will need to make sure that everything is fine with the crank mount.

It is also possible that the device’s motor may fail. You can check its performance using a standard multimeter or a 12-volt light bulb. It is recommended to ensure that the wiper switches are working properly. Perhaps the problem lies precisely there. If nothing helps at all, then perhaps the reason lies in the mounting block itself. Repairing it yourself is impossible, so you will have to turn to professionals. Also, the car enthusiast can install a new mounting block and solve the problem this way.
