What Causes the Grinding Noise When Rolling Up or Down the Car Window?
2 Answers
It needs to be judged specifically according to the situation. Identifying the cause of the noise: First, determine which door's window is making the noise: If you're not sure, close all the doors and roll each window up and down from the driver's seat to identify the problematic window. Spraying dashboard wax: After identifying the noisy window, roll it up to the top. Then, take the prepared dashboard wax (available at automotive supply markets or accessory stores) and spray it evenly into the gap between the exterior felt strip (the sealing strip on the outside of the window glass) and the glass. Avoid using too much, but ensure it's evenly applied. After spraying, roll the noisy window up and down two to three times. This should eliminate or reduce the noise. If the noise persists, the issue may originate from inside the window regulator, and professional assistance is recommended. Cleaning dust: Finally, use a clean cloth to wipe off the dashboard wax from the glass to prevent attracting more dust.
I noticed a friction sound when rolling the windows up and down, which mostly occurs during my daily commute. The main reason is excessive dust accumulation in the window tracks, causing increased friction during operation due to long-term lack of cleaning. Another possible cause is hardened or aged rubber seals losing their lubricating effect, coupled with insufficient grease on the window regulator. My DIY solution involves spraying window-specific lubricant on the tracks—cleaning off the grime usually eliminates the noise. Neglecting this minor issue can lead to more serious problems like stuck windows or even burnt-out lift motors, resulting in much costlier repairs. Regular inspections are crucial; take a moment to clean door and window gaps during car washes to maintain smooth track operation. Spending a little time on maintenance extends window lifespan and prevents safety hazards.
