Why is there a clicking noise when the car window is rolled up to the top?
2 Answers
Here are the possible reasons for the clicking noise when the car window is rolled up to the top: 1. It may be caused by aging of the window seal strip. After the seal strip ages, the friction increases, resulting in the noise. In this case, the problem tends to be more noticeable in summer because the aged seal strip expands more severely after exposure to the sun, increasing friction and making the noise more pronounced. 2. It could be due to dirt in the gap between the glass and the seal strip. Particles in the dust rubbing against the glass can also produce noise. 3. The glass guide rail might be dirty. 4. The issue could be caused by a malfunctioning window lift motor.
Last month, the window of my old car made a clunking noise when rolled up to the top. After checking myself, I found that the window guide rails were clogged with dust, causing dryness and poor rolling. I first used a vacuum cleaner to clean the tracks, then wiped off the residue with a damp cloth, and finally sprayed some professional window lubricating silicone grease, which eliminated the noise. If the problem persists after lubrication, it might be due to loose screws on the glass bracket or wear on the regulator chain. In such cases, don’t force it; take it to a 4S shop as soon as possible for a technician to disassemble and adjust it. I perform rail maintenance every month to prevent debris buildup and extend its lifespan. Proper window operation not only reduces noise but, more importantly, ensures a tight seal to prevent leaks during rain. If the clunking sound becomes more frequent, be aware that the window motor may be wearing out quickly. Replacing new components might cost a bit, but safety comes first.
