What Causes the Abnormal Noise When Car Windows Roll Down?
2 Answers
Car windows produce abnormal noise when rolling down due to the following reasons: 1. Loose fastening screws or window regulator brackets inside the window glass; 2. Aging of the window glass sealing strips; 3. Debris in the window glass guide rails. Car windows are an essential part of the vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. They are categorized into front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. Solutions for abnormal noise when car windows roll down include: 1. Tightening loose door glass at a professional repair shop; 2. Replacing the window glass sealing strips; 3. Cleaning debris from the guide rails.
I encountered the same issue with my car a couple of days ago—the window made an annoying squeaking sound when rolled down. I figured it was probably due to dust and sand accumulated in the window gap. Over the weekend, I used a small brush from home to clean the window tracks thoroughly, inside and out, three times. After cleaning, I also sprayed some window lubricant, the white spray kind that helps maintain rubber seals. If the noise persists, it might be due to aging seals—my colleague’s five-year-old car became quiet immediately after replacing the seals. However, the worst-case scenario is a deformed window regulator. Last year, my brother-in-law’s window got stuck halfway with a loud click, and upon disassembly, they found the regulator was bent—costing over 500 to replace. Parking away from areas with lots of leaves can save a lot of trouble in the long run.
