The main malfunctions of power windows and how to fix them

Finalization of ESP VAZ 2110

1. Modify the ESP (power window) fastening, then the glass will go lower, but not all the way.
2. Make a small cut in the door for the glass, then the glass will be completely hidden in the door

And now in detail:

Modification of the VAZ 2110 electric window

This method will allow you to lower the glass 40mm lower, that is, only 10mm of glass will remain sticking out of the door. It will not be possible to lower the glass even lower into the door, because the standard ESP mechanism and the design feature of the door and glass do not allow this (the glass rests against the edge of the door). The point of this method is to remake the holes for fastening the ESP in the door, as well as attaching the glass itself to the ESP mechanism. Required:

1. Drill (drills for 5, 6 and
2. File (small circular)

Procedure: Re-drill the holes for fastening the glass to the ESP to the very bottom. Lower the lower fastening (stop) of the glass, which prevents the glass from falling lower. We lower this elastic band lower by 1-2 cm. We drill out the welding of the stop, we take everything out

Button

Another reason why the power windows on a VAZ 2114 do not work may be the control button. Inside it there is contact between the plates, the strength of which deteriorates over time. As a result of this, it completely disappears, and the button stops responding to pressing.

All buttons must be in good condition, as they are connected in series. If one fails, you won't be able to diagnose the problem by removing it from one door and putting it on another. In this case, you will have to purchase a new button and switch them around, identifying which one has stopped working.

The price is within 200 rubles, so carrying out such diagnostics is not that expensive.

Main stove malfunctions

As we have already mentioned, the stove is connected to the internal combustion engine cooling system. Accordingly, heating problems may arise for the following reasons:

1. Insufficient amount of coolant in the system.
2. Clogging of radiator tubes.
3. There are air pockets in the system. To eliminate them, you will need to unscrew the cap of the radiator or expansion tank and let the engine idle for a while.

There are a number of cooling system malfunctions that can also affect the performance of the VAZ-2109 heating system. We look at the most common ones.

The weak point of the heating system is the valve through which antifreeze enters the heater radiator. This unit may leak. In this case, it must be replaced with a new one.

Poor quality coolant causes damage to rubber pipes due to its aggressive chemical composition.

Check the condition of the pump, which is responsible for pumping antifreeze and circulating it in the cooling system.

Poor operation of the stove can be caused by incorrect operation of the electric motor that drives the heating system fan.

If you notice extraneous sounds in the operation of this motor, this is a signal for a number of problems:

1. Possible overheating due to fuse failure.
2. When operating at low speeds, warm air does not flow - the electric motor has failed or there has been a break in the electrical circuit of the heating system.

Check the condition of the heater core regularly. It can become clogged during operation, and this provokes an insufficient supply of antifreeze. To carry out preventive work, you need to dismantle this element and wash it. If the part cannot be cleaned, then it is better to buy a new one and replace it.

Experienced car enthusiasts claim that the problem of poor operation of the stove may be a loose fit of the damper. Because of this, cold air from the street enters the cabin, and warm air goes to the feet. To solve this problem, just adjust the damper using a special control lever. It is located next to the gas pedal. Use pliers to tighten the cable that goes to the damper. Make two turns around the head of the bolt that secures the cable to the control arm.

If these steps do not help solve the problem, then inspect the joints of the pieces of foam rubber or plastic. Perhaps cracks and gaps have formed there. You can solve the problem with the help of sealant or simply change the insulation.

Prevention and care of the VAZ-2109 stove

To avoid problems with the stove in cold weather, it is recommended to periodically maintain the system. Use the following recommendations:

Clean the radiator from internal contaminants that may accumulate during long-term use. Use only high quality coolant. You should not save on such consumables. Low quality products can clog the system or damage the rubber pipes. Accordingly, it is better to use a good antifreeze than to subsequently incur additional expenses on repairing the cooling or heating system. Check the thermostat's operation regularly. This device is designed to maintain a certain temperature in the system

If the unit jams, the liquid will not flow into the stove radiator, and the motor will begin to overheat. Pay attention to the condition of the fan bearing. From time to time it is recommended to lubricate this element.

To summarize, we note that in the absence of preventive maintenance during the operation of the car, in any case, problems with the heating system on the VAZ-2109 will someday “come out”. In the article we looked at how the stove on the “nine” works, as well as the main malfunctions and ways to solve them. If you were unable to identify the reason for the incorrect operation of the VAZ-2109 heating system, then we recommend contacting a service center. This approach will save you time and money.

Tracks or contacts in the mounting block

Another reason may be a broken contact of the mechanism relay in the mounting block.

Considering the circuit of the mounting block, we can conclude that a constant plus comes to pin 30 through a fuse, and when we turn on the ignition, we apply another plus to pin 85. As a result of turning on the ignition, an electromagnetic field appears, which closes pins 30 and 87, which provides power to window lift buttons.

This means that if the operation of the plus on the ignition switch is disrupted, the contacts stop closing, even if the relay is in working condition. You can check this by closing contacts 30 and 87 directly, then the plus will come without the ignition switch and if the problem is in it, then the power windows will work.

The video demonstrates another solution to this problem:

But there may also be the opposite situation, that we do not have a constant positive supply to pin 30, and when we turn the ignition key, the contacts close, but nothing happens. In this case, it is best to ring the contact with a tester and find out whether there is constant voltage. For testing, you can connect the plus directly to pin 87, but this is not safe, since the wire will go outside the fuse.

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

RESULTS

If the window regulator does not work, start by finding the cause of the breakdown, and then proceed to fix the problem. Most often, the malfunction can be fixed independently, without the involvement of specialists. This also applies to situations where it is necessary to remove the window regulator for repair or replacement.

During the operation of the car, the window lift mechanism often breaks down. This is mainly due to high production. Initially it fails on the driver's side, since this system is most often used on this door. But if one component breaks down, the power windows on each door of the car may fail. What to do in this case? Let's take a closer look at how to solve the problem when the power windows of a VAZ 2114 do not work.

Welcome! Today you will learn how to correctly change the window regulator on VAZ cars of the Samara family.

• Replacing the window regulator
• Additional video materials

Where is the window regulator located? It is located on the inside of the door, under the trim. In this regard, it can only be clearly seen when the trim is removed from the car door. Below is a photo in which the arrows indicate the location of the window regulator:

When should you replace your window regulator? Usually, when it fails, the window may stop raising and lowering by turning the window lifter handle!

How to replace the window regulator on a VAZ 2108-VAZ 21099?

Removal: 1) First, remove the trim from the car door on which you are going to work. (You can find how to remove the trim in the article: “Replacing the door trim with a new one”)

2) Now remove the side glass from the car door, using the article on “Replacing glass on the side door of a car”.

3) Then, using an extension with a socket head, unscrew the two nuts that secure the middle part of the mechanism guide.

4) Next, unscrew another nut of the lower fastening.

5) And then unscrew the upper fastening nut.

6) Now, using the same extension cord with a union head, completely unscrew the three nuts that secure the window lift mechanism itself.

7) And to complete the operation, remove the window regulator through the hole in the inside of the door.

Installation: 1) First install the new window regulator in its place. And after installation, tighten all the bolts and all the nuts that secure it.

Note! The power window mounting bolts and nuts include: 1. Three power window mechanism mounting nuts. 2. And also the nut for the upper fastening of the guide. 3. Lower fastening nut. 4. And two nuts for the middle fastening of the mechanism guide. 5. And the last bolts that secure the glass to the mechanism.

2) Once the window regulator is installed, proceed to the final installation of the glass and door trim in place.

Additional video materials: More detailed instructions for replacing the window regulator can be found in the video clip located just below:

Note! From the video clip you will learn: How to remove and install trim from a car door, and it will also include detailed removal and installation of glass, and in addition to all this, the window regulator itself will be replaced with a new one!

Fuse

When problems appear with the operation of the mechanism, the first thing to check is the condition of fuses F5 and F16. F5 is the fifth from the top on the left, and F16 is the bottom on the right. They are responsible for the operation of the window lift mechanism on the car. Fuse F1 may also affect the operation of the power windows.

Remember, the element cannot burn out just like that; this usually happens when the wire is short-circuited to body ground. If during replacement the new protective element also burns out, you need to inspect the entire system wiring diagram.

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.

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.

Repair

Repairing this mechanism, as mentioned above, is not difficult if you know the design and operating principle. In particular, let's consider the ESPD mechanism itself, which is not a gear reducer, like mechanical varieties. In electric front door lifting mechanisms, only a drum is used. It is into the hole of this drum that the gear motor shaft is inserted. The gearmotor itself consists of a worm-type gearbox, as well as an electric motor that runs on current from permanent magnets. The design of this gearmotor is similar to the design of the windshield wiper device. As for the direction of the current in the armature winding of this gearmotor, it is reversible. And the built-in thermobimetallic fuse perfectly protects it from overloads.

Door ESPD connection diagram

To be precise, the ESPD circuit consists of:

• block;
• front door ESPD switch;
• ESPD gearmotor;
• ignition switch;
• relay;
• external lighting switch.

So, let's begin the repair process:

• disassemble the upholstery, remove the window regulator (how to do this was written above);
• You now need to remove the cable part from the motor mechanism;
• completely remove the cable from the reel;
• unwind it.

Note. You will need to carefully inspect the splines, which are often worn out. In addition, if the splines remain like this for a long time, they deform the landing cylinder, which creates a huge load on the gearmotor motor.

• grind the protruding parts of the cylinder on a milling machine;
• we restore the roundness of the cylinder.

Note. In this case, you will need to ensure that the bulges on the back side of the cylinder, which appeared due to the rotation of the drive shaft, are ground off.

• We take a two-millimeter steel plate, from which we cut out a circle of a suitable size;

Cut a circle from a metal strip

• after this you need to mark the stiffening ribs on the circle;
• We put the plate in place.

Note. It is desirable that the plate fits tightly and with some effort.

• Assemble the coil in reverse order.

There is no need to attach the plate itself additionally to the coil, because it already sits securely. And the design of the ESPD body itself is made in such a way that it does not allow the plate, even a homemade one, to become loose and fall out. As for turning the plate, everything is reliable here because of the stiffening ribs. Let's continue:

• wind the cable onto a reel;
• install the cover.

Note. Do not forget to thoroughly lubricate the cable with some kind of lubricant, for example, lithol or grease.

• put the cable in place, tightening it a little using a special bolt;
• Now all that remains is to install the ESPD in the door.

Usually this is enough for the glass to go down and up normally again. The speed of glass lifting may even increase compared to what it was before the repair. After all, restoring the roundness of a cylinder, especially an ESPD that has been in operation for a long time, will only be beneficial. Its friction and resistance to the engine are reduced, and this, in turn, has a positive result. It is recommended to watch this video before starting work.

We recommend starting your search for a problem by classifying it, thereby narrowing the list of causes to two groups:

Why does the window regulator raise the window slowly?

Many owners of old cars are familiar with the situation when the window lifter does not rise well, as a result they have to help the glass with their hands. Most often, the problem is that the velvet covers and rubber glass guides are worn out and prevent the glass from freely lowering or raising. In this situation, you can replace the glass seals with new ones (for example, use velvet seals from Priora), or simply lubricate all rubbing areas with a special product, for example, silicone spray or polymethylsiloxane liquid PMS-100: Sometimes something interferes with the free movement of the glass. This could be due to dirt or a misaligned door guide. A similar case was noticed on VAZ-2109-21099-2114-2115 cars, in which the glass is pinched in the area of ​​the rear view mirror. To solve the problem, just slightly bend the edges of the frame outward from the axis of the door. To do this, you will need two hammers, unfold one and use the handle to rest against the inner edge of the frame, and carefully bend it along its entire length towards the interior, hitting it with the second hammer. We similarly modify the outer rib.

In other cases, the window regulators work slowly due to malfunctions of the electric motor (see ESP repair). By the way, some ESP models work faster than others. Do you know which ESP is better to choose?

Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2.

Connection diagram for power windows on doors on cars of the VAZ 2110 family: 1 - mounting block; 2 — ignition switch; 3 — right front door power window switch; 4 — right rear door power window switch; 5 — gear motor for the electric window of the right front door; 6 — gear motor for the electric window of the right rear door; 7 — gear motor for the electric window of the left rear door; 8 — gear motor for the electric window lifter of the left front door; 9 — left rear door power window switch; 10 — left front door power window switch; 11 — relay for turning on electric windows; A - to power supplies; B - to the instrument lighting switch; C - the order of conditional numbering of plugs in the power window blocks

If the window regulator malfunctions, for example, when you press a button, the window opens, but does not lock and immediately closes itself. Or the button stops working until you turn the ignition off/on. The cause of the problem is the button. It should be removed, the contacts cleaned, and replaced if necessary.

Basic malfunctions and methods for their elimination

There can be many reasons for the malfunction, here are the most common ones.

Warm air does not flow well into the cabin or does not flow at all

Malfunction of the fan or switch handle - one of the common reasons is a breakdown of the electric motor of the fan, wiring, or switch handle.

Test methods - to check this fault it is necessary; turn on the vehicle ignition, turn the control lever to the first position, listen.

The sound of the fan should be audible in the cabin, if not, then you need to open the hood and listen there. If the sound of the fan is not heard, the reason is in it or the switch.

Troubleshooting - remove the fan motor, check it, if it is fixed, check the serviceability of the wiring and the switch handle and fix the problem.

Malfunction of the air ducts - if the fan is working, but the air does not enter the cabin.

Test methods - to check, you just need to turn on the heater fan, open the air ducts and check with your hand one by one whether air is supplied to the windshield, side windows to the feet and the top of the driver and passenger.

Elimination - you need to check the air ducts; most likely they are clogged with dust, leaves or fluff. If again air does not enter the cabin, you need to check the functionality of the air duct dampers.

Cold air is blowing from the stove VAZ 2109, 21099

On a frosty winter day, going on a long trip, planning that this trip will be comfortable thanks to the stove, turn it on and... be horrified, because cold air is coming from the stove! What to do in such a situation?

The simplest way to solve the problem is to tighten the radiator damper cable. It can be found on the radiator housing, located near the gas pedal.

Front-wheel drive VAZ models often experience a breakdown such as incomplete opening of the heating tap. Diagnostics is carried out by comparing the temperature of the radiator pipes. In the case when the temperatures differ, we can say with confidence that the tap is not closed completely, which is why cold air is blown out instead of warm. The solution to the problem lies, again, in tightening the valve control cable and adjusting it.

It also happens that the air pumped by the stove escapes through the cracks in the air vents. Leaks lead to this problem. A simple sealing of the seams will help return everything to normal and again enjoy the warmth of your favorite stove.

Antifreeze leak VAZ 2109

Antifreeze leakage in the ninth VAZ model is one of the most common problems. This suggests that, first of all, you need to work on the cooling system; it’s time to change the pipes.

But why does the release occur?

Firstly, this may well be trivial wear and tear of components. As a rule, hoses and pipes fail to work properly, since they are made of fragile material in VAZ cars.

Low quality parts, as well as defects and wear, directly affect the health of the radiator. Components from a careless assembler lead to multiple problems that have the most detrimental effect on both the heating system and the entire operation of the car.

One of the most vulnerable elements of the stove is the expansion tank. Plastic, this word alone makes one suspicious, is not able to withstand such powerful loads that fall on this part, which is certainly important for the car. And, if many foreign cars are equipped with a reliable, durable tank, the domestic manufacturer has not yet thought of this trick and year after year produces cars with a plastic tank that regularly becomes incapacitated. It is useless to repair it; it is easier to replace it with a new one.

Now it’s worth figuring out how to determine the release of coolant.

If oil stains remain under the car when parked for a long time, there is no doubt that antifreeze is leaking.

This problem can also be determined by the smell: during normal operation of the car, the interior should never smell of it.

Sometimes you can see white smoke coming out of the exhaust pipe. Poor quality gasoline? It’s possible, but more likely it’s an antifreeze leak.

You can prevent breakdowns by regularly checking the condition of the car and its components for wear, especially the timing belt.

Now that all the basic m are known

points regarding the malfunction of the VAZ 21009 radiator, you can safely try your hand as a car mechanic. A little skill, patience and a detailed description of the diagnostic procedure will help you avoid mistakes and unnecessary expenses at the service station.

Good luck on your journey!

A little theory

Electric windows have long been used by car enthusiasts; they have significantly increased the level of comfort in the car. Naturally, like everything else, this innovation was put into practice by foreign manufacturers. The domestic auto industry picked up this idea much later.

Speaking abstractly, in terms of build quality, foreign manufacturers are head and shoulders above the Russian auto industry (however, there are significant differences in prices, service and components).

What does it mean? Everything is very simple

, a connoisseur of Russian cars will have to constantly struggle with minor (and not always minor) problems that arise, such as broken window regulators.

If your car was equipped with power windows with mechanical handles, then the cause of the breakdown is easy to find. Most likely, someone, driver or passenger, exerted extra effort and the mechanism gave way. In this case, it is necessary to disassemble the car door from the inside; I remove all the trim.

If the electric lift does not work, then everything is also quite simple. The door on which a similar problem occurred should be disassembled in a similar way. The mechanism of electric window lifts consists of a non-separable motor, which can simply burn out and require replacement. There is also a cable with a bar coming from it. Before replacing, of course, it is necessary to check whether an electrical signal is received by the motor.

Perhaps the reason lies not in the mechanism itself

, but let’s say, in a faulty button, or in other electrical equipment. It is necessary to check the fuses that are located under the steering wheel on the right (under the cover, read more in the car user manual).

Fuse F5 is usually responsible for power windows. If the fuse is intact, then use a multimeter to measure the voltage at the motor terminals. To do this, you can use a regular 12V light bulb.

No voltage?

It is necessary to carefully check the wiring coming from the motor, inspect the relay and control unit. Very often, auto mechanics have to see problems with the button that controls the window regulator. Don't fix it, if it's the problem, just replace it.

It's not expensive and won't cause headaches in the future. If there is voltage on the motor, but it does not work, most likely the drive brush is stuck. You can solve this problem by pressing the button and turning the motor axis. If the cable breaks, it needs to be completely replaced.

If the fault cannot be identified, we move on to the mechanism relay. In the diagram it is marked with a special icon and is designated K5. Located at the bottom left. To check the functionality of the relay, it is better to replace it with a known working one and see if the mechanism functions.

The relay is responsible for closing the contacts when the ignition switch is turned on, so that there is no additional battery consumption when the car is parked. But over time, it may stop working, which is why even with the ignition on, voltage will not be supplied to the system.

Learn more about how to replace a window regulator in a car with your own hands in the video below (author - channel In Sandro's Garage).

It often happens that the electric window lifter of the “tens” famously lowers the window, but refuses to raise it back, and the motor does not make a sound. What could be the reason?

Many car owners in such a situation think about a malfunction inside the button and other complex things. However, often everything turns out to be much simpler. It is not clear why, but it is on the VAZ-2110 that the wire responsible for raising the glass often breaks, and it breaks at the point of transition from the A-pillar to the door. Probably the reason is its unfortunate location and constant bends from opening and closing the door.

Finding such a malfunction is extremely easy. To do this, you need to disconnect from one side the corrugation, inside which the wires pass into the door. Now take a screwdriver and use it to pry off all the wires from the harness one by one. The color of the wires for the window regulators is different in different doors; in addition, the color may differ depending on the year of manufacture, so it is impossible to clearly say what color wire you should look for. The point of checking is that the torn wire will be pulled out of the bundle quite easily and then it can be easily restored.

If, as a result of manipulations with a screwdriver, it turns out that all the wires in the harness are intact, then the cause of the window regulator malfunction is more complex and you need to look for it elsewhere. But if the broken wire is still found, then we restore it. This can be done by simply stripping and twisting the two ends together. Read how to connect wires in a car. After the twist is ready, insulate it with electrical tape. Straighten the wire in the harness, turn on the ignition and try to raise the window. If this is successful, then the problem has been resolved. You can install the corrugation in place and enjoy the excellent performance of the window regulators.

Why is repair needed?

You have to resort to window regulator repair for various reasons. And most often the cause of the malfunction lies in the electric motor. This is explained by the fact that the engine housing itself is not sealed and moisture can enter it. As a result, rust appears inside, which destroys the mechanisms. If the window regulator does not work on a VAZ 2114 or another model, it is recommended to start repairs by disassembling the door. But first, let's look at the types of lifts used today:

• rack and pinion windows, which are considered the most reliable of all others;
• Cable SPDs, which are installed standard on VAZ models;
• plank SPD.

Depending on which manufacturer produces ESPDs, they can be installed in standard locations without much modification. If they don't fit, then it's okay. The window regulator can be easily rebuilt. In addition to the fact that SPDs differ in type of design, they can also have different motors. Thus, an electric motor of domestic or imported production can be installed on window regulators. It is because of this that the difference arises between SPDs, which may have:

• different speeds of lowering and raising the windows;
• different noise levels during operation;
• ability to work in winter conditions, etc.

The window regulator slowly raises the glass - what should I do? There is a solution!

Hi all! Dear friends, you are all aware of what “jambs” and shortcomings each of us “happy” owners of domestic VAZ cars have to eliminate. Today’s article is another life-saving solution for those who are faced with the problem of poorly functioning beet lifters.

Electric windows (ESP) have been installed on foreign cars for decades, so, as a rule, there are no problems with them, which cannot be said about VAZs. On “our” swallows, such a miracle has been occurring for about 10 years, and as practice shows, the good old “meat grinders” in the form of a simple mechanical handle worked much more reliably. Get to the point! A defect was noticed on many models from 2109 to 2115, where, as a rule, the front right glass does not rise well. Moreover, the window lifters slowly raise somewhere from the middle or even lower, the glass slows down or stops rising altogether. At the same time, drivers help the ESP either with their hand or with a “clarion word”.

How does the stove work in a car?

Before you begin to identify the reason why, when the car is stopped, the stove refuses to heat, we recommend that you understand how heating works. After all, knowing the basics of its functioning, you can easily find a breakdown.

Both the small sedan and the truck are made of metal. Therefore, the body is strongly affected by temperature changes:

• In hot weather, the car warms up to a temperature of 40–50 degrees Celsius. In winter, it will be only a couple of degrees warmer in the car than outside. To move your car comfortably during the summer months, we use an air conditioning system.
• During the cold season, you can maintain optimal temperatures in your car using a heating system. Moreover, in our country you have to use the stove most of the year, so it must provide heat.

Previously, the car was warmed up using a stove-stove, as well as gas lamps. And only in 1917, they began to install an autonomous heating system on cars produced in America: the car began to heat up due to the heat from the exhaust pipe. For example, this heating method was used in the 1929 Ford Model A. In addition, cars began to warm up with an installed radiator, which was blown by a fan. This heating system was used on General Motors models. Over the years, every car began to be heated using such a system.

Each modern car is equipped with a heating unit, which is made of such components as:

• fan motor;
• air duct system;
• inlet and outlet pipes;
• stove heat exchanger;
• faucet that regulates the supply of coolant;
• heating equipment control unit;
• dampers, the drive of which can be mechanical or electric.

Usually the car is equipped with a stove, which is located behind the front panel. 2 tubes extend from it, supplying coolant to the radiator. It moves thanks to a pump (pump) both through the engine cooling system and through the heating system.

Heat exchange is possible due to the heating of the motor. Its cooling occurs due to antifreeze: it takes away thermal energy. The heated antifreeze enters the radiator of the stove, which heats according to the same principle as a standard battery in your home. At the same time, the stove fan starts working. It ensures the movement of cold air through the radiator. Here again there is an exchange of heat: the air is heated by the radiator, cooling it at the same time.

The heated air flow is directed into the cabin, and the cooled antifreeze enters the engine, where the heating process begins again. This heating system is used in most cars because its efficiency is quite high. In winter, the car will warm up provided that air with a temperature of 30 degrees Celsius is blown from the stove. This not only ensures that the interior is warmed up, but the windows also remain fog-free. A blower mode switch is installed on the dashboard. With its help, you can change the location of the dampers that regulate the air flow. It can be directed straight, down, up.

Almost all the time, warm air should be directed upward - that is, onto the windshield. This is the only way to maintain an optimal level of pressure in the cabin, when condensation does not form on the glass, and dust microparticles do not penetrate inside the car.

The stove plays the role of another radiator. Therefore, when the car is cold and you turn on the heat, the entire system begins to cool down. As a result, the walls of the radiator rust, the engine, like the car, takes longer to warm up. Air humidity rises, windows fog up from the inside. This means that the stove can only be turned on if the coolant temperature has risen to at least 50 degrees Celsius.
