Right rear door glass does not rise or fall.
The glass of the right rear door will not rise and fall because the lifting function is closed, the glass guide groove has foreign bodies or is dirty, the glass lifting motor is overheating, and the control switch is faulty.
1, turn off the lifting function: now the car is basically equipped with the function of closing the co-pilot and the two rear door window glass independent control, after pressing the function switch, you can not use the glass lift switch on the door control glass, the switch is usually on the driver's side door panel;
Solution: open the window lifting function for the vehicle;
2, the glass guide groove has foreign bodies or is very dirty: many models with slightly higher configuration are equipped with Windows and doors glass anti-pinch function, glass guide groove has foreign bodies, guide rubber aging, accumulation of too much dust may trigger the anti-pinch function, so that the glass can not go up;
Solution: It is suggested that the owner can take the toothpick to clean up, if the cleaning adhesive can go to the 4S shop or repair shop for maintenance, the owner can not solve this problem or easily make the car produce new problems, causing unnecessary losses;
3, glass lifting motor overheating: the rise and fall of Windows and doors glass are controlled by the lifting motor, frequent lifting glass will cause the lifting motor overheating, thus entering the overheating protection mode. At this time, the lifting function of the door and window glass will temporarily fail until the temperature of the motor drops and it will return to normal;
Solution: It is recommended that the owner go to the 4S shop or repair shop for maintenance, the owner can not solve this problem or easily make the car produce new problems, causing unnecessary losses;
4, the control switch failure: the service life of the car is longer because the number of times to control the lift is more, so the control switch failure also occurs. In the early stage, it is necessary to press hard to have a reaction, and in the later stage, it directly fails;
Solution: It is recommended that the owner go to the 4S shop or repair shop for maintenance, the owner can not solve this problem or easily make the car produce new problems, causing unnecessary losses.
The lifting switch is one of the buttons with a relatively high frequency of use on the car, and it is easy to have a decrease in sensitivity or failure for a long time. The specific replacement steps are as follows:

How to wire the glass regulator switch
1, one is the positive pole of the small lamp, two are the positive and negative poles of the power supply, and the other two are the power cord of the lifting motor, which is connected to the rise, the reverse connection to the fall or vice versa, so that you can measure it is simple. First use the voltage to measure, one pen on the iron, the other pen measurement.
2, the three are the main loop, the other two are one of the control loop, the other is the control loop neutral line. You only need to verify that the purchased model is consistent with the model and plug in the corresponding plug. Automobile automatic elevator is the lifting device of automobile door and window glass, mainly divided into electric glass elevator and manual glass elevator two categories.
3, two of them are two wires with the control motor, one is connected with the 15 (B+) terminal, and two are connected with the main control two wires. Power on the elevator and use a multimeter to measure each line. The line with voltage to the ground is live.

5, car electric door and window switch circuit wiring diagram: electric window system by the window, window glass elevator, motor, relay, switch and ECU and other devices composed.
6. Have a firewire that is constantly charged. Automobile glass regulator is a DC motor, the switch is double triple, through the switch to convert the positive and negative terminals of the motor supply, control the rise and fall of the glass.
