What Causes Slow and Weak Power Window Operation?
1 Answers
Window operation becoming slow and weak can be attributed to the following reasons: Low Voltage: The raising and lowering of power windows are driven by window regulators. If the window operates slowly when the engine is off, it might be caused by low battery voltage. This is particularly common in vehicles that haven't been used for extended periods, as battery discharge becomes more likely. In such cases, simply running the engine for a while to recharge the battery and ensure sufficient voltage will resolve the issue. Door Deformation: Although car doors appear very sturdy, frequent forceful closing or instances where doors get squeezed or scraped against objects can cause slight deformations. This may consequently affect window movement, potentially leading to jerky operation. In this situation, carefully inspect the door's condition. If deformation is confirmed, proper repair measures should be taken.
