Why Does the Window Make Noise When Fully Closed?
2 Answers
The reason why the window makes noise when fully closed may be due to damage to the window. Here is a detailed introduction to the maintenance methods for automotive glass: Timely Glass Repair: Use professional tools to repair automotive glass; apply special automotive glass adhesive using pneumatic, electric, or manual professional tools, and remove or install automotive glass. Sealing Inspection: Use inspection tools to check the sealing of replaced automotive glass. Regular Inspection of Related Components: Use instruments and meters to inspect, test, and repair related control circuits and electronic components, and address various electrical and mechanical faults that occur during the glass installation process.
After the window is closed, there is an abnormal noise, which I have pondered many times. The most common possibility is that dust or sticky substances have accumulated in the guide rails of the window regulator system. When the window is fully raised, the edge of the glass rubs against these impurities, causing a squeaking sound. Another scenario is loose screws inside the door panel, where metal parts collide with each other during vibrations, especially noticeable when driving over bumpy roads. Additionally, aging and cracking of the sealing strips can also produce abnormal noises, particularly when temperature changes cause the strips to contract, resulting in a 'zipping' sound. Last year, I personally cleaned the tracks by using cotton swabs dipped in alcohol to remove grease and then applied white lithium grease to the tracks, which eliminated the noise. If DIY methods don’t work, it’s advisable to check whether the window motor is functioning abnormally, as worn motor gears could also be a potential cause.
