What Causes Car Window Glass to Not Roll Up?

[VonJasper]

The reasons why car window glass cannot roll up: 1. The window switch is faulty; 2. The window regulator screws may be loose, which is often accompanied by vibration and abnormal noise from the glass; 3. The window regulator is stuck, causing all window regulators to stop working. When the car window glass fails to roll up, the owner can initialize the window switch. The initialization method generally involves turning on the ignition switch, pulling and holding the window switch upward until the glass reaches the top, then continuing to hold for more than 3 seconds. Release the switch and immediately press and hold it downward until the glass reaches the bottom and hold for more than 3 seconds. Then, pull and hold the switch upward again until the glass reaches the top and continue to hold for more than 3 seconds. The initialization is then complete.
