What to Do When Car Window Makes Sand-Grinding Noise During Operation?
2 Answers
The solutions for car windows making sand-grinding noises during operation are: 1. First thoroughly clean the window glass, lower it completely then raise it fully, repeating this process several times; 2. Spray some lubricant into the window tracks or replace the outer window weatherstrip; 3. Recommended to visit a repair shop for adjustment or replacement of the entire window regulator assembly. Car windows are crucial components of vehicle bodies, designed to provide interior lighting, ventilation, and visibility for occupants. They typically feature curved sealed structures with rubber seals connecting the window frame to glass. Depending on installation positions, there are front/rear windshields, side windows, and door windows.
Last time I drove, I encountered the same issue—there was a noise like grinding sand when rolling the windows up and down. This is usually caused by dust or sand accumulation in the glass guide channels, which can lead to noise over time. I suggest you first try cleaning those channels. Use a soft brush or vacuum to remove the dirt, then spray a specialized lubricant, such as silicone-based lubricating oil. If the noise persists, it might be due to wear on the window regulator tracks, so check for deformation or rust. Don’t underestimate this noise—it can accelerate component wear, and if the glass gets stuck, it’ll be even more troublesome. It’s best to maintain the door and window gaps every six months by wiping the tracks clean with a damp cloth. If you can’t handle it yourself, take your car to a repair shop immediately to replace the parts—safety comes first. Don’t delay too long, or it might cost more to fix later.
