On many domestic cars of old models there is no glass window. But technical progress moves forward, and car owners try to upgrade their "iron horse". To control the windows, keys are used, which over time can fail. About this further in the article.

Window button, cause fault

The reasons why the window button may not respond to pressing, are different:

• Glass lift breakdown.
• Frozen glass with severe frost.

In fact, it is impossible to detect a breakdown without disassembled the windows mechanism. Removing each element, it is necessary to check it for integrity. The main reasons for breakdowns can be divided into two categories:

• The problem with the power button.
• Cases are possible when everything is in order with the electronics, but the window switch does not work.

Structural button, troubleshooting methods

If the problems appeared due to the power supply, first of all it is necessary to check the fuses. If they are in order, carefully inspect the motor motor mechanism and check the voltage on its terminals. The check can be performed using a multimeter or a conventional 12 volt light bulb. If there is no voltage, check the wiring, relay and control unit.

If the button works systematically (then it is starting, it works), most likely, the problem is in it itself. In this case, disassemble the windows, dismantle the button and read the contacts in case of their oxidation.

Repair the window of the window card do it yourself

To independently repair the button, you need to know how to dismantle it. For disassembly, do the following:

1. First dismantle the door panel.
2. Then disconnect the connector and unscrew the mount, with which the button holds the button.
3. Four contacts are located on the board. Carefully clean them if they oxidized.
4. When the button is pressed, it presses on the plastic platform, which presses onto her shell of rubber. As a result of these actions, contacts are closed on the board. It is also desirable to check the springs and every part for good condition.
5. Next, apply to the surface of the shell of rubber conductive glue into a place where the printed part of the board and contacts come into contact.
6. When the adhesive will die, make the details assembly in the reverse order.

When repairing it is important not to confuse the contacts during the connection of the switches.

Connect the window of the window in your own hands

To connect the mechanism button lifting the glass, you need a whole set of materials and tools. If the installation is performed on several doors, you will need so many sets as doors.

Tools and materials

• pistons for doors (7 pieces);
• wire with a cross section of 0.75 (4 meters);
• jack and a glass of key;
• keyboard key;
• terminals like "Dad" (2 pieces);
• terminals of the "Mom" type of large size (2 pieces);
• mom terminals of a small size (7 pieces);
• connector for connection;
• pad "Mom Pope", which has two contacts.

Directly installed

If the windows button is installed directly at the door, its installation will consist of such actions:

1. Before work, de-energize the car, removing the negative terminal with the battery.
2. Remove the trim to provide access to the power window mechanism.
3. The window key is mounted on the driver's door, stretch from it the wiring to the doors where the same buttons will be mounted.
4. To a black and white wire for 12 volts, which is located on the mechanism relay lifting the glass, you must connect two wires by 12 volts of red.
   
5. On the TC doors are gray and blue wires, which are connected to the windows motor. Prepared wires Connect to the block connector: black wire to gray, and the black and white wire is to the blue.
6. Five wires must be connected to the button. The black wire is responsible for "mass", a 12 volt voltage is fed to the red, the white wire is the backlight of the windows buttons, the black and white wire goes to the blue, the black wire from the block is connected black.

Wires with terminals are connected according to the following scheme:

• Red 12-volt connected to the hole at number 2.
• Black and white - to the hole at number 3.
• White - to the hole at number 4.
• Black (from "Mass") - to the hole at number 5.
• Black (gray) - to the hole at number 6.

It is very important to properly connect all the wires to the desired connector jacks, otherwise the control key will not work. After that, take the wires of black and white and the black color of the corresponding length and insert the black wire into the socket at number 1, and the black and white - in the socket at number 2. Free ends crimp with a large terminal "Mom" and connect them to a new connector.

Follow the connected black and white wire to be directed to the blue wire, and the black wire is on black. At this stage, the connection is considered completed. It remains only to install a glass, as well as a keyboard key, securing them with the help of the sealant in the specially done connector in the door trim.
