Why is there a strange noise when the window rolls up to the top?
2 Answers
Possible reasons for strange noises when the window rolls up to the top are as follows: 1. Aging of the sealing strip: It may be caused by the aging of the glass sealing strip. After the sealing strip ages, the friction increases, resulting in strange noises. In this case, the problem is more noticeable in summer because the aged sealing strip expands more severely after exposure to the sun, increasing friction and making the noise more pronounced. 2. Dirty gaps: If the gap between the glass and the sealing strip is too dirty, particles in the dust rubbing against the glass can also produce strange noises. 3. Dirty guide rails: Dirty glass guide rails can also cause strange noises.
When encountering squeaking or friction noises as the window reaches the top, this is usually attributed to several common causes. On one hand, the rubber seals around the window may have aged and hardened over time, losing their elasticity and causing friction against the glass, resulting in unusual sounds. Alternatively, insufficient lubrication in the window tracks or accumulated dust can make the lifting process less smooth. Having driven for decades, I've often seen such issues in older car models. If ignored, the problem tends to worsen, potentially leading to the window jamming or water leaks, which can cause mold inside the car. The simplest solution is to purchase a rubber protectant spray from an auto repair shop, apply it to the seals, wait a few minutes, and then test the window operation—most noises will disappear. Regular maintenance like this can significantly extend the window's lifespan. Another possibility is misaligned glass; even a slight deviation can produce strange noises, requiring professional adjustment.
