What are the reasons for the failure of Volkswagen door window lift?
2 Answers
The reasons for the failure of Volkswagen door window lift include: 1. The lift function is turned off: Most modern cars are equipped with a function to independently control the window lift of the passenger side and the two rear doors. After pressing this function switch, the window lift switch on the door cannot be used to control the window. This switch is usually located on the driver's side door panel. 2. There are foreign objects or dirt in the window guide channel: Many higher-end models are equipped with an anti-pinch function for door windows. Foreign objects in the window guide channel, aging guide channel rubber, or excessive dust accumulation can trigger the anti-pinch function, preventing the window from rising. 3. Overheating of the window lift motor: The lifting and lowering of door windows are controlled by the lift motor. Frequent operation of the window can cause the lift motor to overheat, entering an overheat protection mode. At this time, the window lift function will temporarily fail until the motor temperature drops and returns to normal. 4. Faulty control switch: In older vehicles, due to frequent use of the lift function, control switch failures are common. Initially, it may require pressing harder to get a response, and eventually, it may fail completely.
I think the issue of Volkswagen door window regulators failing is quite common. Having driven a Volkswagen for over a decade, I've encountered it several times. Possible causes include aging or burnt-out lift motors, especially in older models where the motor can fail from overuse. Faulty switch buttons due to poor contact or water-induced short circuits can also cause malfunctions – I've had instances where pressing the button did nothing until I cleaned out dust with a cotton swab. Loose or corroded wiring inside the door is another frequent culprit; door harness connectors can vibrate loose over time, and simply reseating them might solve the problem. Track jamming is another concern – accumulated dust and debris can cause the glass to stick, making regular lubrication maintenance crucial. Blown fuses aren't uncommon either; check the fuse box location (the manual specifies replacement types). Safety-wise, avoid forcing the window up or down when it malfunctions to prevent component damage, and promptly visit a repair shop for inspection.
