On the road with a breeze to the VAZ 2107: device, repair and installation of power windows

Power windows are an integral part of driving a car. The driver should be aware of the main malfunctions of this unit and how to fix them on their own, as well as know what to do if the glass is jammed, fallen, or it becomes necessary to remove / install the lifter. Of practical interest is also the choice and self-installation of power windows on the VAZ 2107.

Power window device VAZ 2107

What is a power window, every motorist knows. Its functions are simple: open and close the window, thereby adjusting the microclimate and the level in the cabin. There are two types of power windows: manual (colloquially, crutches or meat grinders) and electric, controlled from the dashboard or individual buttons.

At the factory, manual power windows were installed on the VAZ 2107, which have a fairly simple design. They are based on the operation of a mechanism to which glass is attached with the help of special fixing devices. The side windows are lowered and raised by turning the handle located inside the cabin.

What are the power windows on the "seven"

During its existence, the VAZ 2107 car was equipped with two types of power windows:

1. Rack. They are considered more reliable. Installation of this type of power windows completely eliminates the skew glass. The operation of the mechanism consists in transferring the rotational force of the gear, which interacts with the linear type rack, to the glass carriage. The main disadvantage is the need for constant lubrication, since the gears of the mechanism were made of plastic, which wears out rather quickly and can damage the entire mechanism.
   

   Rack and pinion power windows are considered more reliable, but require constant lubrication
2. Rope - in their design, they are weaker and more likely to fail. The fundamental element of this type of power windows is a cable connected to a torsion mechanism. The device works rather slowly due to the low functional properties of the drive, which overcomes the resistance of the sealing rubber with effort. It can also happen that it starts to overheat and at some point simply fails. The advantage of this type of mechanism is its good maintainability, but too frequent need for repair practically cancels this advantage.
   

   Cable power windows often fail, but are highly maintainable

Power window malfunctions and how to fix them

The operation of the power window is set and adjusted by the manufacturer, so you should intervene in it very carefully and carefully, otherwise jamming of the mechanism, crunching and crackling may occur.

From personal experience, I advise you to carefully study the device and read the detailed troubleshooting instructions before proceeding with the self-repair of the power window mechanism. Even if it seems that many of them are quite possible to eliminate, armed with a screwdriver and a wrench, in some cases it may be necessary to completely replace the power window.

Before proceeding with self-repair, it is necessary to study the power window device and the principle of its operation.

Power window creak

At first glance, the creak of the power window does not seem to be a serious malfunction, but this signal should be paid attention to, as this is the first sign that the mechanism is wearing out and may soon break. Methods of dealing with such a symptom are extremely simple, accessible to everyone and do not take much time:

• lubricate the power window - for these purposes, lubricants of any manufacturer, widely represented in car dealerships, are suitable;
  

  At the first manifestations of a squeak, the power window must be lubricated
• replace the rubber bands in contact with the glass. When the window is open, dust and sand inevitably get into the car interior, which scratches the glass and rubber bands, resulting in a creak. The ingress of dust and moisture through the gap between the glass and the seal can further lead to jamming of the mechanism, so it is necessary to regularly monitor its cleanliness.

Power window jammed

The main reasons that the VAZ 2107 window lifter is jammed are as follows:

• breakdown of the welded joint connecting the cable bracket and the glass bar to which it is attached. In this case, you need to disconnect the power window cable and weld the bracket;
• the cable is tangled or twisted inside the power window mechanism. You can try to just remove and reinstall the cable. In case of failure, the entire mechanism will have to be replaced;
• wear of the power window gears - indicates the unambiguous need for their replacement.
  

  Worn gear needs to be replaced

falling glass

It happens that the glass falls and is not kept up. The reason for this may lie in the weakening of the fastening of the tension roller, which creates the proper tension in the cable. To repair the damage, it is necessary to restore this mount. Another reason for the malfunction may be that the end of the cable flew out of the fastener. Then you need to remove the power window and try to wind the cable again.

It is easy to check whether you have completed the repair with high quality: in good condition, the window lifter handle rotates freely and without effort, the glass rises easily, without getting stuck and without extraneous sounds.

Repair window lifter VAZ 2107: step by step instructions

Most window lifter failures in a VAZ 2107 car are easy to fix. In most cases, regardless of the design and mechanism, it is the teeth of the rotating gear that break. To start the repair, first remove the trim and the car door card with all the elements placed on it. Then the window lifter itself is removed, after which the necessary work is carried out.

Removing the power window handle

One of the most common malfunctions is handle breakage, which occurs on both front and rear power windows due to inaccurate use or simply over time.

For several years of owning a VAZ 2107, we were convinced that in the event of a breakdown, it is better to change the handle immediately, since repairing it helps for a short time and is not economically feasible. The cost of the window lifter handle for the “seven” is from 20 to 80 rubles in different car dealerships, so you can replace all four handles at the same time, choosing their appearance to your taste. You can even choose and install beautiful handles from other cars.

Replacing the handle is easy, it happens in the following order:

1. Release the handle from the plastic retainer called the retaining ring. To this end, with a screwdriver with a flat tip, the outer ring is moved away from the inner ring and then the retaining ring is removed.
2. Take it off and install a new one in its place.
   

   In order to remove the window lifter handle, you need to move the retaining ring with a flat screwdriver

We remove the power window

To remove the window regulator, you must sequentially perform the following steps:

1. Lower the glass to the stop and remove the power window handle.
2. Loosen the door handle bolts and remove it.
   

   The door handle in the VAZ 2107 has three attachment points
3. Remove the door trim to gain access to the power window mechanism.
4. If you plan to install the window lifter back, you need to tie the cable with wire so that it does not come off the guide grooves.
   

   Securing the cable with wire when removing the power window will facilitate its reinstallation
5. Loosen the bolt securing the lower roller.

7. Remove the power window cable from the rollers.
8. Unscrew the three nuts securing the power window mechanism to the door.
   

   Unscrew the nuts securing the power window mechanism to the door one by one.
9. Pull out the window lifter.

Installing a new mechanism

To install a mechanical window lifter, you need to perform the following steps:

1. Lubricate the power window cable.
   

   Before installation, the power window cable must be well lubricated.
2. Insert the window regulator into place and tighten the three nuts securing the mechanism to the door.
3. Install the cable on the rollers.
4. Remove the wire if you fixed the cable at the disassembly stage.
   

   The wire that binds the cable is the easiest to eat
5. Adjust the tension of the cable and tighten the nut securing the lower roller.
   

   The power window cable is tensioned by tapping a hammer on the head, put on the tensioner roller bracket bolt
6. Check the operation of the power window.
7. Install door trim.
8. Tighten the door handle bolts.
9. Install the power window handle, securing it with a lock washer.

Replacing the cable

It happens that the power window mechanism is working, and the cable is torn or twisted. Replacing it is easy, but you need to consider the following features:

• before installation, be sure to generously lubricate the cable with grease;
• the lower branch of the cable is fed to the upper roller of the mechanism, and the upper one goes down. So that the branches do not get mixed up, it is recommended to tie them with a wire, which, after the final fixing of the power window mechanism and the necessary adjustment procedures, is removed;
• in the VAZ-2107 power window device there is an upper hidden roller. From the first attempt, it is almost impossible to put a cable on it. Let's go for a little trick - at the top of the cable we twist the loop and lead it to the place where this "invisible" roller is located. We move the loop alternately up and down and after several unsuccessful attempts, it catches on the roller.
  

  The upper roller is hidden under the door trim, so you can only put the cable on it by touch, twisting the cable in a loop

Replacing the rollers

The design of the VAZ 2107 cable window lifter includes four rollers, between which the cable moves, with ends fixed on the drum. The first roller is tension, its task is to ensure the necessary tension of the cable throughout the entire operation, because it can stretch during operation. The two upper rollers are connected to the glass brackets by means of tension plates. As a result, when lowering and raising the glass, these rollers move with it. The lower roller is motionless, it is fixed on the door.

To replace the rollers, it is necessary to unscrew the fasteners on which they are held and install new parts.

So, you can deal with the main malfunctions of the VAZ 2107 manual window lifters on your own. However, even if the malfunction seems possible to fix on your own, for your own safety it is preferable to install a new mechanism. Now, in most cases, electric windows are installed on the "sevens" instead of manual ones.

Installation of power windows on the VAZ 2107

The convenience of operating glass from a button, saving time and effort, increasing the attractiveness of the car interior without annoying handles - this is an incomplete list of the advantages of electric windows. Therefore, the owners of "classic" cars, in particular, the VAZ 2107, when replacing, install them on their car.

Modern power windows VAZ 2107 are distinguished by increased reliability, the possibility of self-installation and allow you to control the glass of the doors with a light touch of a button. They successfully work in tandem with the alarm, providing automatic closing of the windows when the car is armed.

Choosing the type of electric window lifter

There are two options for installing and connecting power window kits:

1. With the preservation of the factory standard mechanism and the additional installation of an electric motor. This is a simpler and cheaper way, but it increases the risk of failure of the entire system when the motor overheats.
2. With the installation of a separate set of equipment. Its cost is higher, but this method is more reliable in operation.

On the automotive goods market for the VAZ 2107, there are sets of electric window lifters from different manufacturers, the most popular of which are rack-type GRANAT and FORWARD. The power window rail is a housing in which the glass moving device is located - a gear chain drive. A stationary electric motor is already fixed on the rail, bringing the entire mechanism to work.

The set of power windows offered by the seller includes:

• installation instructions;
• two power windows;
• wiring harness;
• two switches;
• decorative plugs for holes left from mechanical windows.

The kit includes two power windows, a wiring harness, switches and decorative door caps.

How to install an electric window lifter on a VAZ 2107

It is quite difficult to install electric windows, but it is possible. It is more convenient to carry out work in a garage or a closed box.

You will need a power window kit, wrenches, screwdrivers, pliers, bolts and nuts of different sizes, glass clamps, wires and fuses. During installation, malfunctions may be identified, the elimination of which will require the purchase of additional spare parts. Be sure to read the instructions before installation.

To connect power windows, you need to determine the place where you will get power from. In the VAZ 2107, this is most conveniently done from the cigarette lighter. If this option is not suitable, then the wiring will have to be carried out from the battery.

An important step after installing the power window mechanism itself is to install the control buttons for raising and lowering the glass. In the VAZ 2107 car, places for such buttons, of course, were not provided, so you can choose a convenient location for you yourself. Keep in mind that the farther you place the buttons from the door, the longer the wires will be needed. Therefore, it is more convenient to place them on the inside door handle.

To install electric window lifts, it is necessary to make several technological holes for fixing the mechanism, and close the old cavities with the included decorative plugs

The procedure for installing power windows on the VAZ 2107 is as follows:

1. Disconnect the vehicle battery terminals to avoid the possibility of shorting the wiring.
2. Raise the window up, securing it with tape so that it does not fall when the mechanical window lifter mounts are removed.
3. Remove the factory windshield.
