Why is there a strange noise when the car window is closed?

Check the window regulator and whether the bracket is abnormally loose. Here is some relevant information about car windows: 1. Types: Car windows are generally divided into four types: front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. The front and rear windows of a car usually use curved glass that is both aesthetically pleasing and provides good visibility, embedded in the window frame with rubber sealing strips or adhered with special adhesives. To facilitate natural ventilation, the side windows of a car can usually be moved up and down or back and forth. 2. Window materials: As early as 80 years ago, glass was installed on the front end of the T-type cars produced by Ford in the United States, using flat glass to protect drivers from wind and rain. In the decades since, the glass industry has gradually become involved in the automotive industry, creating a variety of safety glass types—laminated glass, tempered glass, and zone-tempered glass—greatly improving the performance of automotive glass.
