What to Do When Car Window Glass is Difficult to Raise or Lower?
1 Answers
Reasons and solutions for difficult window glass operation: 1. Window lift motor damage or poor contact in the wiring harness: If there is a burnt smell when holding down the window button or strange noises inside the door panel, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly replace the window lift motor. 2. Motor overheating protection: To protect the power supply circuit, most window lift motors have an overheating protection mechanism. If components overheat for some reason, the motor will enter a protection state, causing the window to stop functioning. In this situation, simply wait for the motor to cool down. 3. Excessive resistance in the glass guide channel: The door glass guide channel is an often-overlooked detail. Over time, dust can accumulate in the guide channel, increasing resistance and making it harder to raise the glass. Regularly clean debris from the window glass guide rails or use lubricating grease for lubrication. 4. Loss of computer data: Disconnecting the battery, interrupting power or ground lines to the window control module during maintenance of other systems, or severe power loss when starting the engine can cause the initialization data for the windows to be lost, preventing them from operating. In this case, the window lift function needs to be reset.
