What Causes the Abnormal Noise in Power Windows?

[DiSienna]

Here are the reasons for abnormal noise in power windows: 1. Loose screws or excessive dirt: The main causes are loose screws or dirty window lift rails that require lubrication. After cleaning the rails, applying grease can improve the situation. 2. Malfunction of window regulator components: Damaged parts such as cables, rails, or sliders usually require replacing the entire window regulator assembly, as individual component replacement is less common. Note: For the above situations, it is advisable to visit a repair shop or auto beauty shop. Alternatively, you can choose to DIY by removing the door panel, lubricating the window regulator bracket, rails, and cables with grease, and then reinstalling them to eliminate the noise.
