What Causes the Abnormal Noise When Car Windows Roll Up and Down?

[MacNatalie]

Here are the specific reasons for the abnormal noise when car windows roll up and down: 1. Aging of window seal strips: Aging strips are often one of the causes of resonance noise in car windows. For new cars experiencing resonance noise, simply applying lubricant may suffice; if the strips are severely aged, it's best to replace them directly. 2. Debris in the window glass guide rails: The gaps in the sealing strips of the window slots can easily allow dust and particles to enter during the window rolling process, which may cause vibration noise in the window glass. If dust and particles accumulate excessively, it can damage the lifting motor, leading to abnormal noise and even affecting the rolling functionality.
