How to Fix a Broken Car Window Switch Button?

[EmilyMarie]

There are many reasons for car window malfunction. Below is a detailed analysis and solution: 1. Window lift motor damage or poor contact in the electrical control wiring harness: If there is a burnt smell or strange noises from the door panel when holding down the window switch 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 the components overheat for some reason, the motor will enter an overheating protection state, causing the window to malfunction. 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 window to rise. Regularly clean debris from the window glass guide rails or use grease for lubrication.
