Reasons for Abnormal Noise During Window Glass Movement
2 Answers
Reasons for abnormal noise during window glass movement include foreign objects in the rubber guide rails, etc. Below are the specific causes of abnormal noise during window glass movement: 1. Dirty rubber guide rails of the door glass: The rubber guide rails of the door glass easily accumulate dust, causing abnormal noise when the glass moves. In this case, you can first clean the dust from the rubber guide rails with water, dry the moisture, and then spray a little rubber protectant or lubricant on the rubber guide rails. The noise during glass movement will then disappear. 2. Aging rubber guide rails of the door glass: The rubber guide rails of the door glass are exposed to sun and rain all year round, making them prone to aging and losing elasticity. Friction between the glass and the aged rubber guide rails during movement will produce abnormal noise. This situation can only be resolved by replacing the rubber guide rails with new ones.
A few days ago, my car window made a squeaking noise when rolling up and down. It turned out to be due to lack of lubrication in the tracks, where accumulated dust caused friction noise, as well as loosened rattling from aged metal parts of the window regulator. I tried adding some automotive-specific grease myself, which temporarily eliminated the noise. However, if dust buildup is ignored long-term or the tracks aren’t cleaned regularly, it may lead to slower or less smooth window operation. Additionally, deteriorated sealing strips can also cause glass friction noise, so it’s recommended to wipe the tracks with a damp cloth monthly as a preventive measure.
