Why does the new car's window make noise when rolling up and down on rainy days?

[ReidLee]

New car's window makes noise when rolling up and down on rainy days because there is a lot of dust accumulated in the window rubber guide channel or the rubber has aged. Accumulation of dust: Generally speaking, if there is noise when the window is rolling up and down, it is because a lot of dust has accumulated in the window rubber guide channel. Therefore, the resistance will increase during the rolling process. Moreover, if there are some particles mixed in the dust, it will make noise. In this case, you only need to wet a cloth with water and wrap it around one end of a chopstick, then fix it with a rubber band. Then insert this end into the glass guide channel and slide it back and forth to clean. Aging of rubber: In addition to dust accumulation, aging of the window rubber can also cause the window to roll up and down unsmoothly, and lubricant is needed to deal with it. Spray it on the rubber. On the one hand, it can lubricate, and on the other hand, it can maintain the toughness of the rubber and reduce the occurrence of cracking. While solving the aging problem, it also plays a certain preventive role.
