The reason for the loud clicking sound when the car window is fully closed is due to dust accumulation in the window rubber guide channel or aging of the window glass rubber guide channel. Below is relevant information about automatic window closers: 1. Introduction: A car window lifter refers to a device that automatically closes the windows for the owner when they forget to do so upon exiting the vehicle, also known as an automatic window lifter, to prevent forgetful owners from damaging or having their cars stolen due to unclosed windows. The window lifter is also called a window closer, car automatic window closer, car window lifter, car automatic window lifter, etc. 2. Function: This product adopts a user-friendly design, intelligently detects the original car status, automatically checks whether the glass is fully raised, and employs a secondary detection mode. The window lifting system will close any unclosed windows to ensure property safety.
A clicking sound when the window reaches the top usually stems from mechanical component issues. When the mounting screws of the window regulator bracket or guide rails loosen, the glass may shift and collide at the highest point; aged and hardened window seals lose their cushioning effect, causing the metal frame to directly impact the door frame; worn or knotted regulator cables suddenly straightening at the top position can also create abnormal noises. Additionally, if the door has suffered minor deformation from a collision, altering the glass's travel path, the window may jam at an abnormal position and produce noise. Such sounds are not only annoying but may also accelerate regulator damage if ignored long-term. I recommend first checking the seal condition and trying some window lubricant spray. If that doesn't work, the door panel may need removal to adjust the regulator position.
