My car is a mid-to-high-end model. The 4-door electric window is standard equipment. It was originally very convenient to use, especially the one-button lift design on the main driver's side, which eliminates the need to always hold down when passing through some toll stations. The trouble with the control buttons is much better than the electric doors and windows of my previous car. But there are also various problems with advanced things. Now, whenever my main driver’s side electric window rises to the top, it will suddenly drop for a while. Every time I close the window, I have to control it carefully, saving trouble. Trouble, is there something wrong with the control system?
Diagnosis and treatment opinions:
Generally, high-end cars will install an anti-pinch function in the design of power windows, which can avoid personal injury caused by accidental operation. During the use of the vehicle, if there are some objects inside the roof frame of the door, when the window rises to this position, the sensor will activate the anti-pinch function to lower the window. In addition, sometimes during high-speed driving, the glass cannot rise smoothly along the track due to voltage, which may also cause the anti-pinch function to start. In this case, it is best to go to a special maintenance station to make adjustments, check whether there is any foreign matter affecting the window lift, and make adjustments.
