What causes the car window to go up and then automatically come back down?

[MargaretDella]

The reasons why the car window goes up and then automatically comes back down are as follows: 1. Tight sealing strip: If the window sealing strip is too tight, when the window rises to the highest position, it will trigger the window anti-pinch function, causing the window to automatically descend; 2. Obstruction in the glass track: If there are foreign objects or dust on the glass track, it can also trigger the window anti-pinch function; 3. Faulty window controller: If the window controller malfunctions, professional repair at a maintenance shop is required. First, check if the window sealing strip shows signs of aging, as it is located at the top of the door frame. If the sealing strip is damaged, it should be replaced promptly. To prevent premature aging of the strip, avoid exposing the vehicle to direct sunlight whenever possible.
