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.

Where is it located and how to remove the wiper motor of the Lada Priora

If your car's windshield wiper refuses to work or moves slowly and stops, then you should change the wiper motor on your Priora.
Alternatively, you can try to remove and disassemble the old motor, check the presence of lubricant in the gearbox, the condition of the armature and its winding, brushes, bushings. The removal of the windshield wiper motor is carried out together with the trapezoid. We dismantle the wiper arms and the hood seal. After removing the plastic plugs, remove the screws holding the frill. Do not forget about the expansion tank hose, which must be pulled out of the insulation by loosening the clamp. Having put the expansion tank and insulation aside, you can begin to dismantle the trapezoid with the motor. Disassembling the windshield wiper motor is not difficult. First you need to unscrew the gearbox mounting bolts. Then unscrew the screws securing the electric motor housing to the gearbox and remove everything together with the armature. You can begin to prevent and repair the windshield wiper motor of the Lada Priora. Assembly should be carried out in reverse order. If you decide to replace a faulty motor, the question immediately arises of which one to install.

When choosing a windshield wiper motor, you have several options to choose from:

Buy an original one at an auto parts store;
Buy a used one for analysis.

These are the most popular options.
But where is the guarantee that after several thousand kilometers this motor will not have to be changed again? There is also a third option - find out which motors from other car brands can be installed on the Priora. The most suitable, as practice shows, are motors from Japanese cars. It is more advisable to install on your Priora a wiper motor from a Japanese car, which is distinguished by its quality and long service life. When choosing a Japanese motor, you need to be extremely careful, because not all models are similar in size and mounts. In most cases, the fasteners have to be overcooked. But it's worth it. The most important condition is that the ex length does not change. If installed from Priora, the splines will be erased during operation. And this is a replacement for the trapezoid.

Don’t be afraid that the Japanese motor has 4 contacts, while the motor from the Lada Priora has 5. The fifth contact is an additional “ground”. If the Japanese one does not have an additional “trick,” then the fifth contact should be screwed onto the body of the motor itself. See the contact designation diagram for both motors.

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.

Removing the trapezium wipers of the Priora

Procedure:

Unscrew the 2 nuts of the lower fastening of the expansion tank bracket (in the front left wheel arch) using a 10mm socket.
Unscrew the 2 bolts of the upper fastening of the tank bracket (in the engine compartment) using a 10mm socket.
Remove the bracket.
Disconnect the block from the wiring harness of the Priora wiper motor by pressing the latch.

Unscrew the screw of the upper heater mounting using a Phillips screwdriver.
Unscrew two nuts No. 1 and bolt No. 2 securing the purifier using a 10mm socket.
Remove the Priora windshield wiper by squeezing the top part of the heater by hand.
If you plan to further remove the wiper motor from the bracket, then do not forget to mark the position of the crank relative to the wiper bracket.

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.

Replacing the windshield wiper motor on a Priora

To replace the wiper motor itself, you must first note the position of the trapezoid bar relative to its body, so that later you can install everything in the same order.

Unscrew the three motor mounting bolts:

And the central nut using a 13 mm wrench. We remove the motor and replace it with a new one if necessary.

Installation occurs in reverse order. The price of a new trapezoid is from 1000 rubles for the original one produced by AvtoVAZ. You will have to pay at least 2000 rubles for the motor.

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.

Removing the windshield wiper trapezoid assembly with the motor on a Priora

The first step is to remove the wiper arms, as well as the rubber seal on the top of the hood. After this, using a thin knife, we pry off the decorative plugs, under which there are screws securing the frill.

Under these plugs we unscrew the screws securing the frill.

Now, again, on the left side, unscrew several screws securing the insulation to the frill, as shown in the photo below.

After which you can remove one part of the frill:

Also, loosen the clamp bolt on the thin hose of the expansion tank and remove it from the hole in the insulation:

The engine compartment insulation is also attached from below, which is not very clearly visible, but in the photo below this screw is quite clearly visible.

Now you can lift the expander up and move the insulation section to the side, as shown in the photo below.

Now you can begin to unscrew the mounting nuts and bolts of the motor with the trapezoid. Top left:

And top right:

But to get to the trapezoid mounting bolt in the bottom center, you must first unscrew and remove the expansion tank mounting bracket. Two mounting bolts are located on top, as can be seen in the photo:

And two more bolts on the inside of the wing, of course, after first removing the fender liner.

Now the platform can be removed and the last bolt securing the Priora trapezoid can be unscrewed.

Now we carefully remove the entire assembly, finding the desired position so that the trapezoid does not cling to the body and heater housing.

There is still one thing left to do - disconnect the block with the power wiring harness.

Now the entire trapeze assembly with the motor can be removed without any problems.

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.

Help determine (participate in the survey) a list of the most common problems associated with the operation of Lada Priora windshield wipers. Timely inspection and maintenance will help you avoid further problems in the operation of your car. Improve weak points with your own hands.

Features of the electric motor design

The windshield wiper base consists of several individual elements. Among them are the following:

lever axis;
electric motor (device that drives the windshield wiper);
brush lever;
brushes;
brush holder;
mounting block;
frame;
gearmotor.

Regardless of the model and manufacturer, such parts are irreplaceable. Variations are explained only by model characteristics. For example, the latest innovations in the automotive industry include upgraded versions with a wide variety of functions.

Some of them have a heating function, some work automatically, reacting to any contact with water or dirt on the windshield. In general, these are all the existing parts of the device, so the next step in learning how it works is to review the basic concepts.

It's no secret that all glass cleaners are very fragile and vulnerable devices that require a lot of care and can break . Such a structural element is forced to cope with all the work of cleaning the windshield, therefore, with prolonged use, a problem such as rapid wear is noticed.

Trapezoid - the mechanism for direct operation of the wipers

One of the most complex mechanisms in the wiper system kit is the trapezoid. Today, no car manufacturer has such a reliable wiper drive mechanism to guarantee long-term operation of the device. Banal jamming of brushes or excessive emphasis on the glass, improper activation of the wipers, freezing to the glass in winter - all these reasons can be detrimental to the trapezoid. Among the possibilities for restoring this mechanism, it is worth highlighting only a few possible steps:

purchasing a new trapezoid is often the best step for domestic cars, in which the wiper mechanism costs about 1000-1500 rubles;
for foreign cars, purchasing a new trapezoid will cost exorbitant amounts of money, so in this case, repairs should be made and broken parts restored;
Often the bushings and tips in trapezoids fail, which are often plastic and are terribly resistant to frost, so they can simply be replaced;
if it is not easy to find a repair kit for a trapezoid for your car, you can try installing bushings and other parts from other cars of a similar class;
Direct replacement of the trapezoid is necessary if even repair work does not eliminate the problem, or after repair the mechanism begins to tap during operation.

There is no intermittent wiper mode - looking for a relay

Often, along with the lack of intermittent mode, problems arise with returning the windshield wiper blade to its original position. In this case, the culprit of the situation is a burnt-out relay. At the same time, the mode of continuous strokes of the windshield wiper blade is present, as well as the mode of accelerated cleaning of the glass. These options for operating the windshield wiper are designed to bypass the relay; they are implemented directly from the handle for switching on the wiper operating modes. When a relay fails, you simply need to replace it by following this procedure:

searching for the installation location of the relay in your car - again, forums, the car’s operating instructions or recommendations from specialists who repair your car will help;
Next, the non-working relay should be removed from the installation location, the device number should be rewritten so as not to make a mistake when choosing a new electrical device to replace it;
go to the store or order on the Internet an original production relay with the same catalog number to ensure normal operation of the wiper on the car;
Having received the device in your hands, take a good look at it, make sure that this is exactly the element that was originally installed in your car at the factory;
turn off the ignition, be sure to check that the wiper switch is in the “off” position and insert the relay into the slot from which the non-working device was removed;
turn on the ignition and check the quality of the wipers, taking into account the new installed electrical part.

Video review of replacing the motor and trapezoid wipers on Priora 2170, 2171, 2172

To more clearly show the entire process of this repair, a video review of the repair will be shown below.

If you have any questions, ask below in the comments or on the channel under the video!

The device has found its application not only in passenger cars, but also in all other types of vehicles. Even large submarines, helicopters and airplanes are equipped with windshield wipers, which perform an irreplaceable role and at the same time have a very simple operating principle. When the wipers operate, excess water, dirt and other foreign objects on the windshield begin to be removed.

Car models have several operating modes: with a given period of time; constant; single. The auxiliary mechanism supplies water to remove large amounts of dust or dirt from the windshield.

How to choose wipers

Windshield wipers come in regular and frameless types. The first ones consist of a metal frame, are noisy and quickly become loose. Since the wipers on the Priora are not interchangeable, it is necessary to select them taking into account the length. For winter, there are special brushes that help combat icing. The VAZ Priora is equipped with frame windshield wipers at the factory. This type allows you to only replace the brushes if necessary, although frameless ones have better cleaning quality.

There are also hybrid wipers - the most expensive option. They borrowed rocker arms and supports from frame wipers, and a plastic body from the frameless type. This option is the most advanced and is distinguished by its durability. Replacing the tape in frameless and hybrid wipers requires certain skills, while anyone can change the rubber bands in conventional windshield wipers.

How to change rubber bands

You can replace the rubber bands yourself, which will save you money on buying new brushes. You will need pliers and a wide blade screwdriver. First of all, to replace the wiper blades on a Priora, you need to install them perpendicular to the arms, press the locking brackets and then pull them out. After removing the wipers, carefully bend the rubber band clamps located at the edges of the pressure plate to a minimum angle. This is done so that the rubber can easily come out of the wiper. It is better to bend the clamps with pliers, as there is a risk of damaging the clamps.

Steering wheel shift paddles are a common cause of problems

Windshield wipers in most modern cars are activated using steering column switches in the form of levers with data on the operating modes of the equipment printed on them. These levers must work well and have the necessary signals to turn on the wipers. Often the handle fails, the switch does not send the necessary signals, and because of this, the wipers themselves do not work properly. The main tasks in this case are the following:

it is necessary to remove the plastic parts of the steering column in order to get directly to the installation site of the wiper switches;
in most cars, the switches are very easy to remove; the maximum work awaiting you will be unscrewing a few bolts;
after removing the switch, you can use a tester to check its operation by connecting the contacts one by one to different terminals and turning on the wiper operating modes;
if the switch really fails, you should simply replace it with a new one, installing it as simply as disassembling it;
If the switch works, you will have to look for other causes of the problem; it is quite possible that the reasons lie in the area where the switch is connected.

Often, wires simply come off the terminals of this steering column switch and need to be returned to their place. Most likely, after carrying out a complete audit of the electrical system, including switches and other important technical aspects, you will be able to determine the problem and easily fix it. You don't even need any special tools or abilities for this. All you need to do is perform a high-quality restoration of the operation of all simple wiper systems. We offer a short video on how to deal with the problem if the wipers suddenly stop working:

Replacing the windshield wiper motor on a Priora

To replace the wiper motor itself, you must first make a mark of the position of the trapezoid bar relative to its body. This is necessary in order to install it back in the same order. Next, unscrew the 3 bolts that secure the electric motor and the central nut using a 13mm wrench. After this, you can remove the motor and replace it with a new one, if necessary. An original trapezoid costs from a thousand rubles, a new gear motor costs from two thousand rubles.

Dismantling the device

In rare cases, the front or rear windshield wiper motor stops working due to some manufacturing defect. The problem is extremely rare, however, if you become a victim of it, there is nothing left to do but start special repairs.

To complete the procedure successfully, perform a complete dismantling . It is no secret that such a process is quite troublesome and time-consuming. Especially if you have to repair a part from old cars, such as Tavria, KAMAZ, Priora, and so on. In this case, you will have to use several separate steps, including unscrewing the nuts that act as fasteners for the levers.

In the future, you can begin to remove the levers themselves from the tapered splines of the drive. If you have any difficulties at this stage, the splines can be treated with penetrating lubricant . Next, the lever drives are dismantled by unscrewing the nuts, as well as removing the rubber gaskets and plastic bushings.

In the harness, the wiring block is disconnected and pulled out using the raised edge of the seal, through a special slot in the partition of the engine compartment. The next step is to remove the windshield wiper .

Now you will have to unscrew the washer from the removed device and remove the spring retainer . And also you can’t do without disconnecting the rod. As a result, all you have to do is dismantle three bolts and remove the engine. After a full visual inspection, begin replacing any faulty parts.

If this does not give any results, the only way out of the situation is to buy a new motor . If the problem is resolved, the glass cleaning system must be reassembled in the reverse order.

Replacement features and diagram

If, after a thorough diagnosis, you were able to determine that the motor is faulty, think about replacing the failed unit. At this stage there are no special difficulties, so even an inexperienced beginner can easily solve the problem.

True, you must understand that the features of the procedure vary depending on the model of a particular vehicle.

Therefore, before performing a series of any actions, pay attention to the technical features of the system , read the service manual for the car.

First of all, you must unscrew the nuts securing the brush arm. The help of a wrench will come in handy here. Then remove them from their installation location. If difficulties arise, use a penetrating lubricant.
Then you need to remove the lever drives by unscrewing the nuts that secure them.
The next step is to disconnect the connector with the wires in the harness and lift one part of the seal through the hole formed.
As a result, all that remains is to dismantle the wiper itself. Then remove the washer and spring mount. After successfully achieving such goals, all that remains is to disconnect the pull rod, unscrew the three screws and remove the motor. Unit repair is characterized by particular simplicity and speed of execution.

In bad weather, driving with faulty windshield wipers becomes unsafe. While driving, the driver must clearly see the space in front of him in order to quickly react and make the right decision in the event of an extreme situation. Over time, the wipers on the Priora begin to work worse and the quality of cleaning decreases - streaks and unwiped areas appear. The reason may be a breakdown of the wipers, motor or brushes. In this case, it is better to repair the windshield wipers on the Priora at a car service center. Since this is not always possible, the question arises of how to change the wipers on a Lada Priora yourself.

Let's sum it up

If reliable operation of the windshield wiper is your priority, you should pay attention to all possible ways that parts may fail. The knocking trapeze should attract your attention and in a certain way force you to examine the situation. Most likely, the knocking will lead to the fact that you will soon have to replace the device with a new one and buy high-quality replacement parts. But it is quite possible that you just need to get to the trapezoid and tighten the fastenings of its parts in order to eliminate the knocking and continue to operate the device perfectly.

High-quality work of wipers is necessary in any car, so you should immediately solve all problems that arise, taking into account their features and technical difficulties. Replacing the relay can be done in a garage, but it is better to change the trapezoid and wiper motor in a service center. This way, you can get the necessary capabilities for operating the machine without any problems and acquire the necessary performance qualities of peripheral devices. Have you ever encountered problems with your wipers?

GUIDE: Reanimating the windshield wiper trapezoid

One day, in the vastness of the mysterious country of the USSR, Yu.M. was born. Luzhkov. And after 73 years, my windshield wipers squeaked.

It all started in winter. At temperatures below -10 degrees, a wild knocking sound began from the area of the right axis of the wipers when driving over the slightest irregularities. As soon as spring came to Moscow, the windshield wipers began to creak SO much during their work that after 20 minutes of driving I wanted to kill everyone around me with my bare hands. At first I sinned on the HORS wipers, which are like real silicone. But a simple test of bending the leashes showed that the squeak does not go away. The creaking itself is heard much more from the interior than from the street.
