What Causes the Squeaking Noise When Closing the Car Door?

[ZoeyDella]

The squeaking noise when closing the car door is caused by repeated collision and friction of the window in its track. Below are detailed explanations: 1. Loose interior panel or audio system: This issue can be detected by shaking the component by hand or pressing on the squeaky area while driving. If the noise disappears, it confirms the problem, and simply tightening the component will resolve it. 2. Rusty door hinge: This condition produces noise when opening or closing the door. Cleaning the hinge and applying some grease will fix it. 3. Aging door seal: Lack of maintenance over time can lead to this issue. The best solution is to purchase a silicone grease for maintenance, apply it to the door seal, let it absorb for an hour, then wipe it off. This method yields excellent results.
