Automotive window lift failure may be caused by prolonged use, where the rubber guide channels of the window glass deteriorate due to aging rubber or dust accumulation. Window lift motor damage or poor contact in the electrical wiring harness: If there is a burnt smell or unusual noises inside the door panel when holding down the window open button for a long time, 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. Motor overheating protection: To protect the power supply circuit, most window lift motors are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, resulting in window lift failure. In this situation, simply wait for the motor to cool down. 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. Regularly clean debris from the window glass guide rails or use lubricating grease for lubrication. Computer data loss: Disconnecting the battery, disconnecting the power or ground wire of the window control module during maintenance of other systems, or severe power loss when starting the engine, etc., can cause the initialization data of the window to be lost, resulting in the window not lifting. In this case, the window lift needs to be reset. The method is: turn on the ignition switch, pull and hold the switch to raise the window, continue holding for more than 3 seconds after the glass reaches the top, release the switch and immediately press and hold it to lower the glass to the bottom for more than 3 seconds, then repeat the raising action once again.
