What to Do When the Car Window Fails to Roll Up or Down?

[Isabela]

Solutions for when the car window fails to roll up or down: First, turn on the ignition switch, pull and hold the switch upward until the window reaches the top, then continue holding for more than 3 seconds. Release the switch and immediately press and hold it downward until the window reaches the bottom, holding for more than 3 seconds. Repeat the upward movement once more to complete the initialization procedure, and the window function should be restored. The reasons for the window failing to roll up or down include: deformation or damage to the window's mud guard, loose screws on the window regulator, damage to the window regulator itself, or misalignment of the guide rail installation. It is recommended not to attempt repairs yourself and to visit a 4S store for inspection and repair as soon as possible.
