Slow operation of Lada Vesta windows - solution to the problem

Electric windows (EP) are one of the vehicle elements that contribute to more comfortable driving. Like any other electrical circuit component, EDs tend to break down periodically. What to do if a car window regulator does not work and for what reasons these components break - read below.

Components of the window lift system

What should I do if the right one does not work or both electronic devices fail? The window regulators may break, leaving them unable to lower or raise the windows. It is possible that the electronic device is jamming or sticking, but before you repair and disassemble the system yourself, you need to understand its structure. The unit itself works by controlling electric motors installed in the vehicle doors and designed to raise and lower the windows.

The system itself includes the following components:

• electric motors;
• switches located in the doors;
• wiring;
• glass

General structure of the ED system

The most common reasons why the VAZ-2114 window regulator does not work

There is no point in arguing that power windows significantly increase the operating comfort of a car. But most drivers also know that they cause a lot of trouble. By the way, when it comes to the breakdown of the mechanism, we must not forget that the problem may not be in it, but in the glass itself. Over time, the holder or seals wear out, which often leads to a banal misalignment, which significantly impedes the freedom of movement of the glass.

The design of the window lifting mechanism is quite simple, but not reliable. And the fact that the safety block is placed in a place where moisture and dirt can easily get in is also not a plus. As you know, the slightest wear of the insulation can lead to a short circuit and breakdown of the entire system.

The most common reasons why a window regulator fails are the following:

1. Damage to the components of the control unit.
2. The contacts have oxidized and the circuit has opened.
3. Disconnecting the power supply.
4. The control button has stopped performing its functions.

Principle of operation

Why do the power windows not work or only the right window does not go up? To understand exactly why the malfunction occurred, it is advisable to familiarize yourself with the operating principle of the unit. Typically, such a system has a trapezoidal design, which allows the windows to be raised and lowered by pressing switches. The buttons themselves can be located in all car door cards or located only in the driver’s door. It is also worth noting that an electric motor is mounted in each door, which operates in two directions.

In addition, each system is equipped with a special relay, the purpose of which is to control the voltage supplied to the electric motors of the structure. Depending on the vehicle, some car models may be equipped with automatic switches that are installed separately for each electric motor. The use of such structural elements makes it possible to ensure normal operation of the entire system if the window regulator is poor on only one door.

Relay

One of the reasons for the breakdown of the glass door lift mechanism may be that the relay does not work or the fuse has blown.

1. Find the safety block under the hood of the car.
2. According to the diagram, determine the location of the relay itself and the fuse, which make up the links of the electric glass lifting mechanism (ESM) chain.
3. The legs of the elements must be clean, with a pronounced metallic sheen.
4. If traces of oxidation, dirt deposits, etc. are found, you need to clean them off. Mechanically or using special means, for example, WD-40.
5. You can check the relay for functionality in the same way as a button. The working element should be removed from another unit and mounted into the ESP system.
6. If newly installed parts fail again within a short period of time, then the problem is in the wiring itself.

A breakdown may occur with the lift motor. It either burns out completely, or the worm mechanism inside it fails. In the latter case, the device makes a characteristic sound when the button is pressed, but the glass remains motionless.

The reason for the breakdown of the ESP may be that it has a common power source and the external lighting. And if the fuse for the foglights is blown out, the window regulator will not work.

Causes of malfunction

So, we gradually approached the issue of malfunctions. What if the window regulator cannot go down or up? Before you remove the window regulator, disassemble and repair it in your car, let's look at the main reasons. If the rear or front windows do not work, the reason may be either electrical or mechanical.

Detailed design of the EP system

Electrical faults

First of all, if the window regulator has stopped working, it is necessary to diagnose the safety element responsible for the functionality of the system. If you realize that the power window is not working due to a fuse, then you just need to replace it. But if the fuse is working, then you will need to measure the voltage at the electric motor terminals. This task can be accomplished using a regular 12-volt lamp or using a tester.

If you find that the driver's window or any other door does not work due to voltage, then you need to further check:

• wiring;
• relay;
• system control unit.

Sometimes a car owner thinks that the window regulator is broken if, after opening the window, it automatically begins to close until the key is turned in the ignition. As a rule, in this case the problem lies in the contacts, which should be cleaned. Much less often, but it still happens that repair of electric windows includes replacing or repairing a button.

Mechanical defects of the mechanism

If, after measuring the voltage, you realize that there is current in the system, but it does not go down or the window regulator does not work at all, most likely the problem is mechanical. As a rule, in this case, something is interfering with the device, so you will have to disassemble the door and look for the reason. Much less often, the reason lies in a failed electric motor (the author of the video is the channel In Sandro’s Garage).

How to raise the glass if the electric seal is broken - there are several options:

1. Purchase a window regulator repair kit and repair the device, after which you can fully use the system.
2. Try to grab the glass on both sides with your hands and pull it up. If the glass falls after being lifted, you will have to disassemble the door and place a support of the appropriate size under it.
3. If you can’t lift the glass with your hands, you can take a fishing hook on a fishing line and lower it into the door card. You need to try to pry the glass and lift it.

How the stove works on a VAZ 2113

Wanting to understand the question of why the stove on the 2113 VAZ model does not heat well, you need to study the design of the interior heating system itself.

Structurally, several main elements can be distinguished. The stove consists of:

• housings;
• radiator;
• radiator pipes;
• ceiling tap;
• air ducts;
• dampers;
• fan;
• control unit.

It is malfunctions on the part of these elements that may be the reason why the stove does not heat well.

Heating of the air entering the cabin is carried out due to the fact that hot air flows pass through a heat exchanger (radiator), inside of which coolant (antifreeze or antifreeze) heated from a running engine circulates.

On VAZ 2113 heaters, it was possible to shut off the supply of cooling liquid to the stove radiator. This allows you to turn off the interior heater when it is not needed. This mainly applies to car operation in the summer.

The supply of antifreeze is shut off with a special tap, which is cut into the coolant supply pipe to the stove radiator.

The radiator itself is located inside the heater housing. In addition to the fact that the housing contains the main elements of the stove, it also does not allow heat to dissipate in different directions and controls its movement throughout the car.

The housing is securely connected to the air ducts. It is through the air ducts that hot air flows can flow to the side windows, onto the windshield, into the passenger compartment, as well as to the feet of the driver and front passenger. To control the flow of air, deflectors are used at the ends of the air ducts.

To distribute air flows to different zones, dampers are used inside the stove body. Structurally, the stove on the VAZ 2113 has 3 types of dampers:

• Control. The first damper is responsible for controlling the stove itself. It is used to redirect the air flow through the heat exchanger (stove radiator), or bypass. In the first case, hot air will flow into the cabin, and in the second, the ventilation of the car interior is simply activated.
• Supply to the windshield area. The second flap helps redirect air towards the windshield. This is a useful feature. Especially in winter. Helps remove ice from glass, as well as get rid of fogging caused by the temperature difference between inside and outside.
• Redirection to the feet, side windows and interior. The third damper, which allows you to choose exactly where the hot air will blow.

Using the stove valve and dampers, the driver controls the interior heater, directs air flows and determines the zones where they will be directed.

There is also an important element in the form of a stove fan, which is part of the heater. With its help, air flows are created. The power supply circuit of the fan motor is equipped with rheostats. This allows you to select one of 3 operating modes. That is, by choosing one mode or another, the fan rotation speed changes

It is important to take into account that rheostats affect precisely the reduction in the speed of rotation of the blades. This is useful to know when identifying stove malfunctions.

The system used on the Samara and Samara-2 families, which includes the VAZ 2113 model, differs from the classic VAZ. Previously, the fan sucked in air. Now the process of pumping air into the stove body takes place. This significantly increased the efficiency of air supply.

Plus, access to the fan has been simplified. Now you can reach it through the engine compartment, near the engine shield.

Instructions for replacing the electric motor

Repairing a window regulator may include different stages depending on the breakdown. In this case, we will tell you how to repair a window regulator by replacing its electric motor; as mentioned above, this problem is one of the most common.

The replacement process is considered using the example of a Lada Kalina car:

1. First you need to buy a new electric motor, which is sold in a housing with a gearbox. The door trim is dismantled - this operation cannot be performed in the cold, since the trim is fixed using plastic pistons, which will quickly break.
2. Unscrew all screws and other fasteners securing the inner handle.
3. All wires must be disconnected; for greater convenience, you can remove the speakers. After these steps, the glass, which is fixed in the guides, is unscrewed. In order for the glass to sink to the bottom, you need to unscrew four more screws; to do this, use a 10 key. There is a curtain at the bottom of the glass unit, which must be removed.
4. The window regulator itself is mounted on nuts and guides, the electric motor itself is secured with three more nuts. The block can be pulled out through the technological holes in the door. If you disassemble the gearbox, the electric motor will fall apart into two parts. In general, the gearbox must be dismantled and replaced with a new one, further reassembling in the reverse order. The gear cable should be lubricated before use.

The second window regulator functions normally. Therefore, there was an assumption (or rather, hope) that the button was to blame. I advised him to try swapping the buttons, maybe it would help.

What other ways could there be to solve the problem other than “disassemble and repair/replace”?

Well, I signed the second proposal for decryption

Oberon86, thanks for the advice. I told him to move and pull this glass. He says: “It doesn’t work.” Although in theory it should help at least somehow.

Added after 1 minute 23 seconds:

Thank you) If it’s a motor, then there are only two options left: either repair it or pull it harder

I also thought he was dead, but when they took it apart, they pulled out the motor, it worked, the glass was just jammed somewhere, they put it back together and everything worked. _________________ Add us, please repost https://vk.com/autoexp68 Phone: 892O2344246
