What are the causes of abnormal noise at the door glass?
1 Answers
Abnormal noise at the door glass is a common issue in many vehicles. The causes of door glass noise are as follows: 1. The door glass rubber guide rail is too dirty or has foreign objects: Dust can accumulate in the door glass guide rail, causing noise when the glass is raised or lowered. In this case, cleaning is required. 2. Aging of the door glass rubber guide rail: When the rubber guide rail ages, you will hear the noise of the aged rubber scraping against the glass when raising or lowering the window. In this situation, a rubber protectant can be used to temporarily restore some elasticity to the rubber and reduce the noise caused by friction against the glass, or the glass rubber guide rail can be replaced.
