What Causes Car Window Glass to Fail to Roll Up or Down?

[SanAxel]

Reasons why car windows fail to roll up or down: 1. The window lift motor is damaged or there is poor contact in the electrical control wiring harness. If there is a burnt smell or 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, window lift motors generally have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window to fail to roll up or down. 3. Excessive resistance in the glass guide channel. The door glass guide channel is an easily overlooked detail. During use, dust accumulates in the glass guide channel, increasing resistance, which over time may make it difficult for the glass to rise.
