Car Door Window Won't Roll Up or Down?

[VonStephanie]

Solutions for car window that won't roll up or down: 1. Window lift motor failure or poor contact in electrical wiring harness: If you smell burning or hear unusual noises from the door panel when holding down the window button, it's likely the window lift motor components are damaged. In this case, it's 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 any reason, the motor will enter a protection state, causing window operation failure. 3. Excessive resistance in window track: The door window track is an easily overlooked detail. During use, dust accumulates in the track, increasing resistance, which over time may make window movement difficult.
