What Causes the Abnormal Noise from Car Door Glass?

[EmersynAnn]

The reasons for abnormal noise from car door glass: 1. The rubber guide rail of the door glass is too dirty or has foreign objects. These dust particles can cause noise when the glass is raised or lowered; 2. The lifting mechanism has dust, debris, or a faulty lifting motor. The door glass is operated by the lifting mechanism below, and the lifting rails and cables are covered with grease, making them prone to dust accumulation; 3. Aging rubber seals can also cause abnormal noise from the door glass, requiring replacement with new ones. Car glass is produced by heating the glass in a furnace to near softening temperature, then quickly transferring it to air grids with different cooling intensities for uneven cooling, creating varying stress levels between the main viewing area and the peripheral areas. Generally, this type of production yields zone-tempered glass.
