What Causes the Noise When Rolling Down the Car Window?

[DeMary]

Window noise may be caused by dust in the window rubber guide channel or aging of the window rubber. The specific reasons for the noise during window operation are as follows: 1. Accumulation of a large amount of dust in the window rubber guide channel: If noise occurs during window operation, it is likely due to a significant buildup of dust in the window rubber guide channel. This increases resistance during the operation. Moreover, if the dust contains some particles, it can produce noise. In such cases, simply wet a cloth with water, wrap it around one end of a chopstick, and secure it with a rubber band. Then, insert this end into the glass guide channel and slide it back and forth to clean. 2. Aging of the window rubber: Besides dust accumulation, aging of the window rubber can also cause noise during window operation. This can be addressed by using lubricating oil. Spray it on the rubber to lubricate and maintain the rubber's flexibility, reducing the likelihood of cracking.
