[Molly]

The methods to fix a car door window that won't roll up are as follows: 1. Turn on the ignition switch and hold the window switch in the upward position. 2. After the window reaches the top, continue holding the switch for more than 3 seconds, then release and immediately press it again. 3. Lower the window completely, wait for more than 3 seconds, and then repeat the upward movement once more. 4. Once the initialization process is complete, the window rolling function should be restored. 5. This method is applicable to most car models, but refer to the manual for specifics. If unsuccessful, visit a 4S shop for repair. Possible reasons for a car door window not rolling up include: 1. Damaged window lift motor or poor contact in the electrical control wiring. 2. Motor overheating protection. 3. Excessive resistance in the glass guide channel.
