What Causes the Rattling Noise in Car Window Glass?

[Jayla]

Window glass rattling noise is primarily caused by: 1. Aging of the window glass sealing rubber strip. If the noise occurs in a new car, there's no need to immediately replace the rubber strip. Simply purchase a lubricant online, apply it evenly on the rubber strip, and then try raising and lowering the window several times to see if the noise diminishes. If the rubber strip is severely aged, it's best to replace it directly. 2. Debris in the window glass guide rail. The gaps in the sealing strip of the window slot can easily allow dust and particles to enter during the window's up-and-down movement, which may cause the window glass to vibrate and produce noise. If dust and particles accumulate excessively, they can damage the lifting motor, leading to noise and even affecting the window's lifting function. The solution is to use tools to clean out the debris in the guide rail. 3. Loose screws or clips. This mainly includes the glass fixing screws, lifting guide rail fixing screws, door trim panel clips, and other screws inside the door trim panel. To fix such minor issues, simply visit a 4S shop and have the staff tighten them.
