The right front window lifter of the Lada Priora does not work

Possible breakdowns

The window regulator on the Priora does not work and this is due to a number of reasons, the essence of which we will look into in detail. So, a passenger car VAZ-2170 Priora can be equipped by the manufacturer with electric windows for:

Two front doors
. As a rule, the two rear doors are equipped with manual rack-and-pinion lifts (window lifters are installed separately on them);
On all four doors.

Depending on the type, devices of the cable and rack operating principle are distinguished. By type, there are faults associated with the electrical and mechanical parts.

The most common mechanical failures include:

“Licking” of teeth on the gear of the lifting mechanism;
Defects in the cable mechanism that led to its damage or excessive stretching, which subsequently causes it to jump off the guide rollers.

As we see, there are few mechanical reasons and they are extremely rare.

Electrical defects

If it happens that all four window regulators fail, then the reason must initially be sought in fuse number F31

, which is located in the central power supply control unit. The manufacturer placed the fuse and relay mounting block under the steering rack. So getting there and checking the condition will not be difficult for any driver, even an inexperienced one.

You just need to open the plastic panel under the steering wheel and perform a visual inspection to find the damaged (burnt out) mechanism.

If you have problems opening the rear doors using the control buttons that are located on the door compartments, but the windows are driven by the central control unit, then we begin to look for the reason in a mechanism called the rear window switch. Often the mechanism randomly blocks the current supply, as a result of which the glass does not move.

Diagnostics are carried out

using a tester. If the product does not pass current, then it should be replaced with a working one, since it cannot be repaired. The cost of the device is low, so there will be no big expenses.

Next breakdown option

when one window regulator is faulty and cannot be moved using the central control unit. First of all, we test the mechanism on the corresponding doorway. If there are no complaints about the operation of the relay button, then we look for the cause in the head power supply, otherwise we replace the faulty relay. We finally check the entire system for serviceability.

In addition, a possible breakdown could be trivial mechanical damage to the electrical wire, as people say, it has become frayed. It can be eliminated by twisting or soldering the two ends of the wire, followed by mandatory insulation for safety purposes.

Now, as for the electric motor itself, the cause of the breakdown may be, and, as a rule, it is, significant wear of the commutator brushes

(freezing). Such freezing occurs due to the fact that the part is structurally made of plastic and, due to heating, can be deformed and modified.

The brush becomes motionless or inactive and is not able to perform its functions in full. Another reason why the power window on the Priora does not work. As you can see, you can eliminate the cause of the breakdown yourself, without having the proper experience, everything is quite simple and clear.

Modern cars are equipped with a number of devices and devices to ensure the comfort of the driver and passengers in the cabin. Among the many devices that provide comfort is an electric window regulator. Often these devices create inconvenience due to their unstable operation or failure. This problem, in particular, is quite common on Lada Priora cars.

A broken window regulator will not allow you to raise or lower your car window. Therefore, if this mechanism breaks down, you should immediately think about repairing it.

How to repair a motor

We have figured out the reasons why the window lifter in a VAZ 2110 car may stop working, and now we will tell you how to fix the window lifter motor with your own hands.

Before repairing the device, it must be dismantled. Do not save time and do not try to disassemble it in the door, as this is inconvenient. It’s better to immediately remove it and pull it out of the door, and then start repairing:

First, remove the gearbox cover with a 5.5 wrench - to do this you need to unscrew 4 bolts.
Remove the driven gear from the gearmotor and check the condition of the teeth on it.
Using a shaped screwdriver, unscrew the bolts that hold the engine.
Disconnect the wires from the engine and note how they were connected.
Insert the wires into the electric motor housing.
Disconnect the gearbox and motor.
Knock the armature out of the engine by holding its shaft in a vice (it is better to wrap it first so as not to damage it). Knock out the anchor through the wooden spacer with light blows of a hammer on the end.
Remove the plastic plug from the base using tweezers or pliers.
Knock out the bushing at the end of the shaft. You can make this process easier by spraying with WD-40. Next, fix the shaft and bushing so that the stop is on the bushing. Insert a thin punch and make a few gentle blows.
Remove any rust from the shaft using fine sandpaper. Additionally, it is recommended to treat the elements with gasoline or solvent.
Press the rear shaft bushing into the body of the VAZ 2110 electric motor, using a thin spacer with a hammer.
Insert the brushes into place and secure with wires.
Place the shaft into the gear housing.
Release the brushes and check for contact between them and the commutator.
Place the previously removed plastic tip on the end of the shaft and thoroughly lubricate it with some lubricant, for example, CV joint-4.
The seal on the wires must be pulled away from the terminals. Insert the wires inside the electric motor housing and then install the seal in place.
Insert the driven gear into the gearbox housing and screw the cover to the housing with four bolts.
Connect the gear housing to the electric window lift motor of the VAZ 2110. This can be done by holding the gear shaft with pliers to prevent it from turning. Otherwise, the anchor will jump out of the gearbox. Secure them with two bolts.

Do-it-yourself repair of the VAZ 2110 window lifter electric motor has come to an end, and all you have to do is check the operation of the mechanism.

Why does the Priora window lifter not work?

Window lifter failure may occur due to a malfunction of the following systems:

The window lift motor has its own wear life; if it is exceeded, the mechanism fails, and the motor itself must be replaced.

If everything is fine with the motor, but the lifts still do not work, then the cause of the breakdown may be an electrical circuit or damaged wires.

"Priors" window lifter block

The car's safety unit contains a component responsible for the car's window regulators. If it fails, the mechanism stops functioning.

The Priora window control buttons can also cause a malfunction. This mainly occurs due to oxidation of the button contacts.

Situations also arise when the functioning of the Priora windows is quite unstable. For example, they can only work when the ignition is on or they work partially. It may be that the front ones function normally, but the rear windows on the Priora do not work. Then, most likely, the problem lies in the car's electronics.

Lada 2114 Logbook The problem with the passenger window not working has been resolved

Good day to all.

Almost immediately after I switched to 2114, I encountered the problem of the window regulator on the passenger side not working at times.
It looked something like this:
Due to the fact that this happened mainly after washing.
I began to sin because the door was somehow miraculously flooding. I start the car, the power window doesn’t work, I drive it, I press it... it’s just miracles. A Google/drive search revealed several possible reasons: 1. Wire break or short to ground at the point where the wires pass from the passenger compartment to the door, 2. Failure of the window lift motor/gear wear on the mechanism.3. Malfunction of the button The blown fuse was dismissed immediately - everything is fine on the driver’s side. Yesterday I had a free evening, I began to disassemble the trim. I examined all the possible wires in the door and was ready to look further, in the corrugation, but... There are two wires in the door connected through a white connector (the wires themselves are white and blue, the photo shows what they look like.

It was discovered that one of the wires on one side had come out of the chip, so, apparently, while jumping on bumps, the contact appeared and disappeared. Therefore, if you encounter a problem of this kind, first check all connections, this way you can get by with little damage)

__________________The 2113 had a tuned radiator grille.
It so happened that before selling it, I installed the factory one I had bought at a disassembly, but this one was left gathering dust + was not in excellent condition, with broken fasteners. I began to make a blind grille out of it (and possibly with holes, and possibly with a mesh). Stretched vertically. to give it a more even shape. I covered it with fabric and doused it with epoxy. Let's see what happens. Peace for everyone.

Causes of failure

Priora window lifts break down due to the car being in conditions of regular low temperatures for a long time, problems with the electronic control unit, failure of fuses, wear of the motor and other lift components, as well as skewed glass.

Before carrying out repairs, it is necessary to diagnose those car systems in which the cause of the breakdown of this element may be hidden. Diagnostics are best carried out using tools and devices, for example, a tester will allow you to understand whether voltage is supplied to the window lift motor.

Once the cause of the problem has been identified, repairs can begin.

The principle of operation of a car window lifter

The ability to switch between raising and lowering the windows is made possible by equipping the electric motor with a reverse power system. Structurally, the motion vector is changed either using a relay or directly through a switch. Window lifters of the latest generations are more complex, which is caused by the need to increase the safety of their use and increase comfort. Functions of modern mechanisms for automatically raising/lowering windows:

uniform movement in one of the directions to the end point;
discrete movement (for example, an inch) in one direction or another;
slow mechanism locking;
return movement (used to have time to remove part of the body from the window opening).

The window regulator control unit is the brains of the device, which includes, in addition to the control microcircuit, an electric motor relay, switches and electrical wiring connecting the control unit to the door lock and the top hatch cover. If you activate the window lift mode with one touch or command, it will move in the specified direction. As soon as the switch is moved to the reverse position, the motor will stop. The same will happen if the power window ECU receives a corresponding signal from the door circuit board.

Troubleshooting control buttons

A fairly common malfunction is the failure of the window lift control buttons. Most often, the Priora power window buttons become oxidized, or their contacts begin to come off. To eliminate faults of this kind, you will need to clean the contacts from oxide or re-solder the buttons. When re-soldering, the contacts will fit snugly against each other, thereby ensuring uninterrupted operation of the power window.

Troubleshooting

Minor breakdowns include glass rattling, noise in the window lifter, free movement of glass under mechanical influence (for example, the glass does not rise or fall with the lifter, but the same can be done by hand). Their cause is skewed glass, failure of rollers or cables. If the glass is skewed, it must be adjusted. If the cable is broken, it must be replaced. If the cable comes off the rollers, you need to pull it back and adjust the car window regulator. The occurrence of noise is a sign that the mechanism is poorly lubricated. To eliminate the malfunction, you need to thoroughly lubricate all the power window mechanisms, as well as the glass guides. If the mechanism operates slowly, it should also be lubricated or replaced with a new one. Over time, the speed of lowering and raising the windows decreases due to wear and tear on the window lift motor.

Malfunctions requiring repair at a car service center

The cause of window lift failure can be not only mechanical, but also electronic faults. This includes a breakdown of the car’s central electronics unit. If it fails, independent repair of this unit is impossible. A complete diagnosis and troubleshooting is required in a specialized service center.

The thing is that the CBKE has a number of multifunctional wires, which at the same time are responsible for the functioning of the central locking, turn signals, electric heated windows and mirrors. Trying to eliminate the electronic cause of a broken window lift can only make the problem worse.

How power windows work on a VAZ-2110

Wiring diagram for electric windows.

This vehicle cannot lower or raise the windows unless the ignition is turned on.

For window regulators, relays rated for a current of 30 Amps are used.

The relay, which is located in the mounting block, is responsible for the operation of the window lifters. It is located in the passenger compartment on the driver's side.

The relay is marked with an arrow.

Results

The Lada Priora car is reliable and unpretentious. However, the power windows of this model often fail. Perhaps the matter lies in the imperfection of the mechanism, perhaps in the harsh operating conditions of the vehicle. These include low and high temperatures, high intensity of use, problems with CBKE.

If the window regulator breaks down, you need to immediately repair it. Repair work begins with diagnostics, which is carried out using a number of instruments. If diagnostics at home is not possible, then you should contact a car service.

A number of breakdowns can be repaired yourself. Such breakdowns include mechanical malfunctions of the window regulator, for example, a broken motor or a broken cable. Often, the glass lift is unstable due to poorly lubricated surfaces. If the window lifts operate separately, then most likely the problem lies in the electronics. If such problems arise, you should contact a specialist. Self-repair of car electronic systems is impossible.

Of course, electric window lifts are superior to mechanical ones, mainly due to practicality. However, electric lifts fail much more often. For their stable operation, it is necessary to follow the recommendations of the car manufacturer and regularly carry out technical inspections of the vehicle.

Modern window regulators are part of the car's electronics. Manual devices have long been a thing of the past; today, electric designs are used. Despite their convenience and practicality, they are considered less reliable than mechanical ones, which means they fail more often.

Any owner of a Lada Priora may sooner or later notice that the window regulator on his car does not work. Front and rear devices have approximately equal chances of failure. However, if your window regulator stops working, the problem must be corrected, because otherwise you will not be able to open or close the window. Some problems can be solved on your own, and in some cases you will have to contact a service center. Today we’ll talk about why the window regulator on the Lada Priora does not work and how to solve the problem.

On what principle does the mechanism operate?

A window lift with an automatic mechanism is an electromechanical device that allows you to quickly open or close the windows of a vehicle. The main idea is the movement of the glass by transferring reinforcement to the glass from the gearbox of the structure.

The device has the following working units:

Drive (gearbox) - helps create the necessary force to organize the movement of glass in the car door. Functions in conjunction with a gear or worm drive. Such a tandem makes it possible to open the window to the required height without further falls.

An on and off system, presented in the form of an ordinary button (with its help you can adjust the rise of the glass to a certain height).

Glass.

Lifting design. The mechanism transmits force from the gearbox to the glass.

The mechanism assumes the following working algorithm:

force is transmitted through a rack and pinion system;

the glass is lifted by a cable;

reinforcement through a system of levers.

Depending on which transmission system is used, one can judge the mechanism to be rack, cable, or lever. Modern foreign cars most often have rack or cable options.

And although the design is quite simple, the system can begin to work incorrectly at any time.

An interesting fact is that the first power windows appeared in the United States in the 40s on Packard180 cars. A year later, the Lincoln automaker began introducing the new system into its seven-seat sedans.

Let's understand the scheme

Before you begin diagnosing a power window malfunction, you first need to familiarize yourself with the features of the vehicle's electrical circuit. If you can master it, there will be no special problems with making a diagnosis. To do this, you will have to find the car's owner's manual; there are separate wiring diagrams for the driver, passenger and rear doors. To diagnose a malfunction, you will need to know the location and connection of the following elements:

Control block;
central locking;
turn signals;
mirrors;
blocks to the rear wiring harness, as well as to the speaker;
window lift motor.

All described elements are indicated in the basic diagram. Why is all this needed? So that you do not mix up the connections and avoid confusion with the car’s electronics. Sometimes there are situations in which, for example, an inexperienced car enthusiast connects the right window regulator to the left side and vice versa.

After you understand the circuit, you can proceed directly to identifying the malfunction and fixing it, if you can do it yourself.

Installation Features

As for installation, it is carried out in the reverse order of removal:

First, the new mechanism is secured with eleven nuts.
Then the wiring and electric motor are connected.
After this, find the screw that secures the inner handle of the lock and tighten it completely.
At the final stage of installation of the front joint ventures, the adhesive tape is removed.
Next, through the hole in the rear door, a new window regulator is installed instead of the old one.
Using a 10 mm wrench, you need to tighten all the corresponding screws and nuts. Use an 8mm wrench to tighten the nuts that secure the assembly. The tape is removed.

After completing the installation, you need to check how correctly the window opens and closes, whether there are any distortions and whether the mechanism as a whole is securely fixed. If mistakes are made, the problem must be corrected immediately so that it does not catch you at the most inopportune moment.

Sorry, there are no surveys available at this time.
