What are the common faults of car power windows?

Common faults of car power windows: 1. The reason why the electric switch window does not move smoothly is mostly due to the exhaustion of oil in the door internal lifter, the inner cover should be removed and oil should be added; 2. If the glass cannot move at all, it may be a switch failure and can only be replaced; 3. If the electronic device does not work, check the fuse, the fuse is used for the power window; 4. When the switch action becomes worse and the window cannot be opened smoothly, the possibility of switch failure is very high; 5. Before oiling the internal mechanical device, first remove the inner cover, remove the hidden screws, and disassemble the quick switch; 6. Remove the inner cover, peel off the plastic paper for waterproofing below, and expose the lifting mechanism of the window; 7. Spray grease on the arm fulcrum and inside the gear, and spray while moving up and down, so that very small parts can also be coated.

I've been driving for several years and often encounter issues with power windows. The most common problems include malfunctioning switch buttons, sometimes unresponsive after repeated pressing, likely due to oxidized or worn contacts; motor failures are also frequent, such as buzzing sounds without movement during operation, indicating the motor might be seized or burnt out; circuit issues often arise too, like blown fuses cutting off power, causing the windows to stop working entirely; problems with the regulator mechanism, such as broken cables or stuck sliders, where excessive dirt or insufficient lubrication leads to rough operation; and windows getting stuck midway, which can be quite dangerous, especially on highways. I've tried using WD-40 to lubricate the sliders for temporary relief, but long-term fixes require a visit to the repair shop. Regularly cleaning the window gaps can prevent many of these issues. In short, minor problems can be handled DIY, but major issues are best left to professional mechanics for peace of mind.

I've had my car windows repaired several times. Based on experience, common issues include motor burnout, poor switch contact, or circuit short circuits. For example, in summer heat, motors are prone to overheating and stopping; in winter, frozen tracks can cause jamming. If the switch button doesn't respond when pressed, it's often due to internal contact rust. Wiring problems are more troublesome, like blown fuses or loose plugs, which can paralyze the entire window system. Sometimes, foreign objects like leaves or stones get stuck in the window tracks, causing squeaky noises during operation. To prevent these, I recommend lubricating the tracks with spray oil every six months and keeping dust from accumulating. If the window suddenly stops working, first check the fuse box with a diagnostic tool. If that doesn't help, it's safer to take it for repair. Maintaining stable battery voltage can also reduce the chance of malfunctions.

I often encounter electric window failures when repairing cars. The switch components are prone to failure, with contact wear causing button malfunctions. Issues with the motor, such as burned-out coils or worn gears, can lead to pauses or abnormal noises during window operation. Wiring faults, including short circuits or open circuits, are common, and fuses often blow. The window regulator mechanism, such as rusted slides or cables, can cause jamming. Improper operation can also trigger problems, like rushing to close the window in winter and freezing the mechanism. For troubleshooting, first check the fuse, then try lubricating the slides. In severe cases, replace the faulty parts. Regular maintenance can extend their lifespan.
