Repair of Priora windshield wiper gear motor

1. Replacing the regulator relay which is located under the steering wheel2. Replacing wiper motor lubrication

In general, I changed both relays, but this did not fix my problem:

It was decided to remove the motor and trapeze to change the lubricant. I used this video as a tutorial on how to unscrew it all:

On my own behalf I would like to add that the trapezoid with the motor cannot be removed easily and simply

To get them you can’t do without a spell and a huge amount of swearing. Even in the video, the wipers are in their standard position, but I read a lot where the wipers are turned on and left in the upper position (vertically) by turning off the ignition, which is what I actually did.

In general, after 5-6 times I still got it right and my joy knew no bounds.

And one more thing: before putting the wipers in place, turn on the ignition and let the engine idle, this way it will make a full swing and get into its working position and you can put the wipers not vertically, but horizontally. Regarding removal and installation, that seems to be all, now about the motor itself and the trapezoid:

In general, we disassemble the motor and see in front of us 3 gears and a lubricant in color and consistency similar to frozen boiled condensed milk.

These 3 gears basically do not hold anything and they can be easily pulled out, the main thing is to remember where each one was. Next, using a rag and WD-40 (whatever was on hand), we clean all this mess, especially from the contacts. We fill in new grease and screw everything back. And regarding the trapezoid there is even less to do, we just rivet these places and lubricate the hinges

Why do VAZ 2110 fuses burn?

By the way, somewhere during the drive I saw that someone had filled in transmission oil instead of lubricant and was trying to do the same thing. I filled it in, tightened it and put it aside to check whether the same oil would leak. As a result, while I was working on the trapezoid, the oil from the motor still ran in the contact area, so I had to drain it and fill the motor with CV joint lubricant.

In general, I spent about 4 hours in the garage, if not more. I am very pleased with the result.

Priora owners note two drawbacks of the windshield cleaning system: slow operation of the wipers and 4 working strokes of the wipers when the washer is turned on, when two would be enough. The article discusses the reasons for these shortcomings and provides ways to solve them by modifying the Priora windshield wiper.

what are the reasons and how to fix it?

Often those who have this car notice that the wipers on the Prior work too slowly, as a result of which visibility deteriorates. This problem is especially typical in winter, when the windows become heavily fogged and covered with snow. Because of this, visibility is greatly reduced, which can lead to dire consequences. To prevent this from happening, you need to repair your wipers on time. However, first it is advisable to understand the cause of the malfunction.

Why windshield wipers do not work well: reasons and solutions

If you notice that the washers on your car are not working well, you need to immediately find out the cause of this problem. Often this is:

Everything can be solved if you approach the procedure correctly. In the first case, it is necessary to choose a solution as a lubricant that does not thicken at high temperatures. If the lubricant does not help, you will have to use a modification. Lada Priora windshield wipers consist of many connections and contacts that create additional resistance, as a result of which the motor power decreases. You can minimize current loss using the following tools:

5-pin connector;
three 5-pin relays with socket;
wires 25 mm;
round terminals.

How to speed up the work of Priora wipers

The problem of slow windshield wipers appears over time. The speed may decrease several times; the windshield wipers begin to move slowly even on wet glass covered in rain. There are three reasons for the malfunction:

engine malfunction;
poor performance of wiper hinges;
problems with the engine power supply.

Motor malfunction may be due to worn brushes or bearings. But the wiper motor is quite reliable, so more often the reason is in the hinges or power supply.

The operation of the hinges can be adjusted using high-quality lubricant. To do this, you need to remove the trapezoid with the motor, wash the hinge joints and apply a lubricant that does not thicken at low temperatures.

Power supply problems are solved by updating the Priora windshield wiper circuit. The wiper switch circuit contains many electrical connections and contacts that oxidize over time. As a result, there is a drop in the voltage supplied to the wiper motor, and it does not develop the required power.

Modification of Priora wipers by installing a five-pin electromagnetic relay, which minimizes current losses in the power circuit.

For this you will need:

5-pin relay - 3 pcs.;
5-pin relay motor connector;
round terminals - 5 pcs.;
wire with a cross section of 2.5 mm.

How to install fender liners on a Chevrolet Niva

The connection diagram involves installing three relays in the wire gap in front of the windshield wiper motor and does not make changes to the standard car wiring (Figure 1). As a result, the voltage supplied to the engine through the contacts and switches of the wipers only controls the activation of the relays, which supply the on-board network voltage to the engine without loss.

Particular attention should be paid to the insulation of the contact wires. The relay unit must be installed in a suitable plastic case and the holes sealed to prevent moisture from entering, which can cause oxidation of the contacts and damage to the relay.

This solves the problem of slow operation of the wiper motor.

When using the Priora windshield washer, the wipers make four passes instead of two, as on most cars.

The first two cycles the wipers scrape dirt and water from the glass, and the last couple of cycles the wipers move over dry glass. As a result, accelerated wear of the rubber bands occurs, and scratches appear on the glass.

This “bug” can be corrected by modifying the Priora windshield wiper. It consists of modifying the windshield wiper relay, after which the number of strokes will decrease.

The work requires minimal skills in handling a soldering iron in order to be able to replace one resistor in the relay.

To upgrade the wiper relay you will need:

resistor 40-70 kOhm;
screwdriver or knife;
soldering iron;
solder;
rosin.

The number of movements of the wipers when the washer is turned on depends on one of the resistors in the relay circuit. Its resistance is 141 kOhm, and for two cycles a resistor of approximately 51 kOhm is required.

To upgrade the relay, you must perform the following steps:

remove the wiper relay from the fuse panel;

use a knife or screwdriver to open and disassemble the relay;
heat the soldering iron;
remove resistor 140 km;

solder a 40-70 kOhm resistor onto the vacant space (with higher resistance, the wipers can make 3-4 strokes instead of 2);

Note: If a resistor of a suitable value is not available, you can replace it by connecting resistors of a suitable value in series or in parallel. For example, solder two 20 kOhm resistors connected in series (you get 40 kOhm) or two parallel connected 100 kOhm resistors (you get 50 kOhm).

assemble the relay housing;
install the relay on the fuse panel;
Check the functionality of the relay by briefly turning on the glass washer.

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.

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.

Instructions for removing and replacing trapezoidal wipers on a Priora without air conditioning

Once all the tools are ready, you can begin the actual process. First you need to disconnect the negative terminal on the battery. You don't need to remove the hood of your car, but if you do this, you will make the job about 30-40% easier. If work is carried out without removing the hood, then it is better to close it. The need to open it will arise when you remove the left side of the frill. To remove the trapezoidal wipers with a motor on a Priora without air conditioning for the purpose of repairing or replacing it, you should perform the following steps:

Initially, the leashes or levers are dismantled along with the wipers. This is necessary in order to remove the frill. To do this, remove the plugs and use a “13” key to unscrew the fastening nuts.
Next, remove the lever. Before removing, squeeze the leash, and only then remove the lever.
Use a screwdriver to pry off the three plastic plugs, under which the frill fastening screws are located.
Use a Phillips screwdriver to unscrew the frill fasteners.
Open the hood.
Move the rubber hood seal aside.
Using a Phillips screwdriver, unscrew the four screws securing the sound insulation of the engine compartment from the top.
And one screw from the bottom, which is located under the brake system reservoir.
Loosen the clamp of the hose coming from the passenger compartment to the expansion tank. Disconnect the hose from the tank and move it to the side.
Remove the frill by pulling it towards you.
Remove the expansion tank from its seat. It does not have fasteners. To remove it, you need to unfold it and pull it towards you.
After this, we remove the hose through the hole in the sound insulation, which was previously disconnected from the expansion tank.
Remove sound insulation.
To dismantle the trapezoid of the wipers and the motor, it is necessary to first dismantle the platform (platform) on which the expansion tank is located. It is secured with two bolts and two nuts. The photo below shows the location of the bolts on the hood side.
The platform mounting nuts are located on the wheel arches on the wheel side.
Remove the platform and set it aside.
Having gained access to the wiper trapeze with the motor, you can begin to dismantle it. To do this, you need to unscrew the two nuts on the “10” fastening of the trapezoid. They are located in the area where the wiper arms are mounted (near the rods). Below is shown the first trapezoid mounting nut on the Priora.
And the second nut for the “10” trapezoid mount on the Priora.
The motor is secured with a “10” bolt, which is located underneath it. It also needs to be unscrewed.
We remove the trapezoid and disconnect the motor power supply. To remove it, you need to twist it in different directions until you get out of the niche. It is important to note that the wipers do not need to be moved to the vertical position first. This will not make it easier to dismantle the trapezoid with the wiper motor on the Priora.
This completes the process of dismantling the windshield wiper trapezium assembly with the motor on the Priora. Further actions depend on the reasons for the need for dismantling. If you need to replace the trapezoid along with the motor, then we install new elements instead of the removed ones. If you need to repair a motor or trapezoid, then we disconnect these parts and perform the appropriate actions.
To disconnect the trapezoid from the motor, unscrew the nut to “10” or “12” (depending on the model of the gearmotor), as well as the three bolt connections to “10”.
Before disconnecting the trapezoid from the wiper motor, you should mark the location of the trapezoid relative to the motor. To do this, we use a marker and use it to outline the location of the trapezoid (or make notches with a screwdriver). This is necessary so that after assembly there is no need to adjust the operation of the wipers.

This is interesting! After installing the trapezoid with the motor in place, do not rush to install the frill. First, turn on the wipers and let them work for one cycle. Then reinstall the wiper arms and check how they work. If everything is in order, then you can continue assembly. If operating defects occur, for example, they do not wipe or start moving down and then up, then they should be adjusted first. The adjustment is made by changing the position of the plate, which is shown by the arrow in the photo above.

This completes the expert instructions for removing and replacing the trapezoid and wiper motor on a Priora. The assembly process is performed in the reverse order of removal. Below is a video clip that details the process of dismantling the trapezoid and wiper motor on a Priora without air conditioning.

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.

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.

If the wipers stop working, the first thing you need to do is check the integrity of the fuse. This is the most common cause of malfunction and can be easily eliminated without resorting to complex technological processes.

Possible causes of the malfunction and ways to eliminate them:

When the windshield wiper is on, the electric drive does not work:

Fuse blown:

remove the cover located to the left of the driver, under the steering column, under it there is a mounting block;
on the cover of the mounting block there is a diagram of the location of the relays and fuses of the car, we find the required fuse and change it if necessary;

Relay fault:

If the wipers on the Lada Kalina do not work intermittently, you need to change the relay located in the mounting block, next to the fuses.

Wiper motor malfunction:

we check the ground terminal of the electric motor, screwed to the car body next to the rack;
we clean it and the attachment point;
install in place;

VAZ 1117 If this does not have a result, disconnect the connector for the electric drive of the windshield wiper, located under the windshield frame.
Using a tester or any other continuity test, we check whether power is coming to the connector. If power comes in, then it is necessary to change the wiper motor. Disconnect the terminals from the battery. Remove the decorative caps from the leashes. Unscrew the nuts securing the leads and remove them. Remove the plastic grille under the windshield frame by unscrewing the bolts that secure it. Having unscrewed the trapezoid fastening (two bolts and one nut), remove the electric motor from the box and disconnect it from the trapezoid. Install a new one by repeating the procedure in reverse order.

If power does not come to the connector. The steering column switch needs to be replaced. Disconnect the battery terminals. Remove the plastic steering column cover. Disconnect the switch block and, pressing the latches on both sides, remove the steering column wiper switch. Install a new one by repeating the process in reverse order. Assembling the casing.

When turned on, the wipers on Kalina do not work, but the electric drive rotates

It is necessary to check the condition of the gearbox and wiper trapezoid.

Unscrew the plastic grill under the windshield frame. First remove the wiper arms and unscrew the nuts that secure them. We check whether the gearbox axis of the electric windshield wiper drive rotates.

In case the axis rotates and the trapezoid is stationary. check the splined connection of the gearbox and trapezoid, if necessary, tighten the fastening nut. If the connection is severely worn, it is necessary to replace this unit.

If your windshield wipers do not work on your Lada Kalina. this is not a reason to despair. As a rule, the cause is a minor malfunction. Such as a blown fuse or a loose nut on the spline connection between the gearbox and the windshield wiper drive, which can simply be tightened.

The windshield wiper electric drive system is quite reliable and does not require special maintenance. It is enough to follow basic operating rules. If during the winter period the wipers are frozen to the windshield, then before turning on the windshield wiper, it is necessary to free them from ice. And they will serve you without causing any problems.

Lada Kalina Hatchback -=First car=- › Logbook › The wipers do not work. Problem with gear motor

Hello everyone! I haven’t visited Drive2 for a very long time. I confess, it’s my fault (Several changes have been made to the machine in a few months =) I will write about everything in more detail in separate blog articles.

So, a serious problem suddenly overtook me. I was driving along the highway, it was raining, I turn on the wipers, they do one cycle and freeze forever... With an astonished look, I try to revive the wipers, but they are silent. I pull over to the side of the road, the first thing I do is check the transmission - everything is ok. I open the hood, visually the rack and the motor are in perfect order... thoughtfully tugging at the contacts near the engine, I took out a cloth, wiped the glass and drove quietly to my destination. I’ll tell you honestly, friends, driving in the rain with non-working windshield wipers is an extreme thing))) God forbid, someone should experience this for themselves.

Lada Priora wipers work slowly

Quote(Kadastro @ 1.9.2008, 21:11)

And if in the latter mode they only work intermittently? Also a trapezoid? And when I put a relay in the fuse block, the wipers start to drive.

in your case, you need to clean the contacts on the motor, they usually oxidize!

Ma_5yka 26 Sep 2008

The fuse is there for a reason, but if you remove it, they will work normally (if the trapezoid is normal) but until the first overvoltage. For example, in the winter, without brushing a snowdrift off your windshield, you decide to brush it off with the wipers, and the motor will be screwed. Because there is no fuse.

MARZOCCHI 26 Sep 2008

Oh how. And then 2 months ago my trapezoid soured completely, I replaced it, but the wipers still work slowly. I was thinking about changing the trapeze again. Well, I'll change the motor) Thanks

Epicurian 26 Sep 2008

the little man will not burn out. The fuse that is located in the mounting block where all the fuses will burn will burn out. and it's the easiest to change!

Why wipers work slowly on Lada Priora and how to speed them up

Many Priora owners notice that over time the wipers begin to work slowly. The speed has decreased several times and does not rise even when cleaning the wet windshield. Let's look at the main reasons for slow wipers, as well as ways to solve this problem.

The main reason for slow Priora wipers is the lack of lubrication:

in the windshield wiper motor;
on the hinges of the windshield wiper trapezoid.

Lamps used on cars

Try to use a lubricant that does not thicken at low temperatures. The trapezoid with the motor can be removed, like on a VAZ 2110.

If lubrication of the motor and trapezoid does not help, we recommend using the modification.

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.

If you understand the Priora electrical circuit, you can solve both mechanical and electrical problems yourself. Contacting specialists is required in rare cases when nothing helps at all.

Have you encountered a problem with the operation of the windshield wiper blades of your Lada Priora? There may be several reasons for this malfunction. If you follow the instructions, the problem will be solved as soon as possible.

Check the condition of the windshield wiper blades; perhaps they are simply frozen to the windshield.
In the mounting block, check the integrity of all fuses. Pay special attention to the serviceability of the windshield wiper fuse (F11 at 10A). Check the wiper relay, which is located in place of K6 (the most convenient way is to replace it with a known working one).
Clean the contacts on the upper connector of the mounting block and on the wiper motor connector. It is also possible that the wiring may be broken.
Check the windshield wiper motor by applying +12V to it directly from the battery.
Check the windshield wiper trapezoid. Maybe the nut from the gearbox that secures the rack has simply unscrewed. Or the rack is jammed due to rust.
Check the electric motor fuse, which can be installed on the trapezoid bracket (the white wire goes in and out of it), or inside the motor.
Check the serviceability of the steering column switches.
In rare cases, it is necessary to change the assembly block.
