When your car window glass won't roll up, you can try the following methods:
1：Initialize the Window: First, attempt to restore functionality by initializing the window. Turn on the ignition switch, hold down the window button to raise the window to its highest point, then release the button, and quickly press it again to lower the window to the lowest position. Repeat this process several times.
2：Clean the Guide Rail: If there is dirt buildup in the window guide rail, use a chopstick wrapped with a damp towel to scrape it out from inside the guide rail, ensuring cleanliness.
3：Lubricate or Replace the Weatherstripping: After cleaning the guide rail, try applying lubricating grease or replacing the aged and deformed weatherstripping to ensure smooth window operation.
4：Window Motor Issues: If there are circuit abnormalities or strange noises, it may be due to a damaged window motor, which requires inspection and repair.
5：Obstructions in the Guide Rail: Dust or foreign objects accumulating in the guide rail can also obstruct window movement, so it's essential to keep the guide rail clean.
6：System Protection Mechanism: Regularly check the window system's protection mechanism and avoid frequent operations that may cause overheating and shutdown.
If the above measures fail to resolve the issue, it may involve abnormalities in the door control module or motor damage. In this case, it is advisable to seek professional technical assistance and visit a repair shop or dealership for repair.
