What to Do When the Power Window Fails to Operate?

[OEllie]

There are many reasons for power window failure. Here is a detailed analysis and solutions: 1. Window lift motor damage or poor contact in the electrical control wiring harness: If you smell burning or hear unusual noises from the door panel when holding down the window button, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly visit a 4S shop or auto repair shop to 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 an overheating protection state, causing the window to fail to operate. 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 easily overlooked detail. During use, dust can accumulate in the glass guide channel, increasing resistance, which over time may make it difficult for the glass to rise. Regularly clean debris from the window glass guide rail or use grease for lubrication.
