What Causes the Noise When Rolling Up/Down Car Windows on Rainy Days in a New Car?

[CarlosDella]

There are many reasons for car window noise, such as aging of the window glass sealing rubber strip, debris in the window glass guide rail, loose screws or clips, etc. The specific details are as follows: 1. Aging of the window glass sealing rubber strip: Aging rubber strips are the most likely cause of car window noise. If the noise occurs in a new car, there's no need to replace the rubber strip immediately. Simply purchase a lubricant online, apply it evenly on the rubber strip, and then try rolling the window up and down several times to see if the noise diminishes. 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 rolling process, which may cause vibration and noise in the car window. If dust and particles accumulate more and more, it can damage the lifting motor, leading to noise and even affecting the lifting function. The solution is to use tools to clean the debris in the guide rail.
