✅ Priora windshield wiper trapezoid installation

The front windshield wiper on the Lada Priora has a design similar to the tenth family, so this repair will be similar. But still, some points will be different. So, repair or replacement of some parts usually occurs for the following reasons:

Windshield wiper motor failure
Trapezoid failure
The occurrence of increased play in the operation of the trapezoid

To make repairs or replacements yourself, you will need the following tools:

Ratchet handles
Extension
Head for 10 and 13 mm

Installation of windshield cleaner VAZ 2170

We assemble and install the Priora windshield wiper trapeze in the reverse order. After this, we turn on the gear motor using the steering column switch, then turn it off and wait until the electric motor shaft stops. In this position of the gear motor shaft, we install the crank along the previously applied mark.

Removing the Priora windshield wiper trapezoid, as well as dismantling and replacing the motor that drives this windshield wiper trapezoid, is slightly different from cars of the tenth family (VAZ 2110-12), since on the Priora the fastening of the frill is different, and the fastening of the sound insulation is also slightly different, so performing this procedure will be a little more difficult . So if you are the owner of a Lada Priora and need to remove the windshield wiper drive trapezoid to repair or replace the motor, then you should still use the visual video instructions so that unexpected difficulties do not arise when removing and installing the windshield wiper trapezoid on your Priora.

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.

Replacing the motor and trapezium wipers

Windshield wiper motor failure
Trapezoid failure
The occurrence of increased play in the operation of the trapezoid

To make repairs or replacements yourself, you will need the following tools:

Ratchet handles
Extension
Head for 10 and 13 mm
Sharp knife or screwdriver
Phillips screwdriver

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?

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.

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.

How to change wipers on a Priora

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.

Most experts recommend replacing windshield wipers on a Priora once a year, regardless of the intensity of use of the car. It is best to change brushes after winter, since this is the time of year that most negatively affects the condition of the entire car. According to technical requirements, windshield wipers must efficiently remove snow and dirt from the windshield for 400 thousand cycles, which is approximately equal to one year of use.

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 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.

After the rubber band is removed from the clamps, you need to pull out the metal plates that hold the curved shape. You should immediately remember the directions of the bends of the plates so as not to confuse them and not to do the work again, since the elastic band will not be pressed tightly against the windshield. The plates have recesses where the rubber grooves should fit. There are situations when the thickness of the groove is greater than the width of the opening. In this case, it can be expanded with a thin file.

Replacing the trapezoid wipers on a Priora

To repair the Priora trapezoid, you will need a repair kit, with which replacing the motor or trapezoid rods will not take much time. First of all, to replace the motor on a Priora, you need to prepare the engine compartment: disconnect the battery terminal with the “-” sign, remove the left side of the sound insulation and move the expansion tank to the side. From the Priora windshield wiper repair kit, you will first need a flat and Phillips screwdriver, as well as a 10mm head.

How to remove trapezium wipers on Lada Priora

In the front left wheel arch, unscrew the two nuts that secure the expansion tank bracket from below using a 10mm socket. In the engine compartment, unscrew the two upper mounting bolts using the same 10mm socket and remove the bracket.
Release the latch and disconnect the block from the motor wiring.
Using a Phillips screwdriver, unscrew the screw on the top heater mounting.
Using a 10mm socket, unscrew the heater mounting bolt and nut, then remove the windshield wiper by pressing out the top part of the heater.
Next, you need to mark the location of the crank relative to the bracket if you need to completely remove the Priora windshield wiper motor.

Installing the windshield wiper trapezoid on the VAZ-2170 occurs in the reverse order. You need to turn on the motor using the steering column switch, then turn it off and wait until the electric motor shaft stops. Next, you should install the crank according to the mark made before.

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.
