What Causes the Squeaking Noise When Car Windows Are Rolled Up or Down?

[DelAddyson]

The squeaking noise when car windows are rolled up or down can be attributed to: aging of the window sealing strips, abnormal noises from the window lifting mechanism, or the presence of sand and dirt in the window tracks. There are sealing strips at the bottom of the door windows. If these strips age, the friction between the strips and the glass increases, leading to noise when the window is operated. Vehicles have numerous sealing strips, and these rubber components can deteriorate over time. It's important to pay attention to the maintenance of these rubber parts during vehicle upkeep. If the sealing strips are not functioning properly, they should be replaced promptly, as poor sealing can result in rainwater leaking into the car during rain.
