Why is there abnormal noise when the car window rolls up?

[DelAaliyah]

Possible reasons for abnormal noise when the car window rolls up are as follows: 1. Hardware issues with the car window regulator, possibly due to deformation of the regulator bracket after long-term use, causing uneven torque when the window bracket rises, resulting in noise. 2. Friction and interference between the window and the inner door seal over time, leading to noise. 3. Small particles of sand or dirt may adhere to the window surface, causing noise when rubbing against the outer door seal during the rolling action. Solutions: 1. Apply an appropriate amount of lubricant for adjustment. 2. Visit a 4S shop for direct repair.

The car window makes noise when rolling up likely due to accumulated dust in the window tracks causing obstruction or heavy friction. Having driven for over a decade, I've encountered this issue multiple times. Initially mistaking it for normal aging, I later discovered dirt in the tracks with dust causing squeaking sounds. Cleaning the track gaps and applying some automotive-grade silicone grease usually solves it. If ineffective, internal components of the window regulator like loose cables or worn gears could also be the culprit. Don't delay addressing this, as prolonged noise can slow down or even jam the window operation. When parking, try avoiding spots under trees to prevent leaves from falling into the gaps. Occasionally cleaning dust with a small brush as prevention is wise. If DIY fixes don't work, simply visit a repair shop for inspection—it's affordable and ensures safety and convenience.

From the perspective of helping my friend repair the car, common causes of glass rattling include insufficient lubrication in the window regulator's guide rails or aging of the regulator mechanism. Especially in dry and cold weather, plastic components harden, shrink, and create friction noise. First, try spraying lubricant onto the rails. If the effect doesn’t last, it might be due to damaged cables or poor motor contact, which requires removing the door panel for inspection—avoid forcing it as excessive force could damage the wiring. Additionally, dried and cracked sealing strips can allow debris into the tracks, contributing to noise. Regularly cleaning the gaps around windows and doors can extend their lifespan. If simple fixes don’t work, seek professional help promptly, as delaying minor issues can lead to costly major repairs and affect driving experience.

As a housewife who shuttles kids around every day, the annoying noise from the window glass is the most distracting and affects safe driving. The main issues are dirt in the tracks causing friction or dry, hardened weatherstrips producing harsh squeaking sounds. I make it a habit to wipe the inner door frames with a damp cloth during each car wash to remove dust and reduce noise sources. Increased noise indicates it's time to take action—don't ignore it to avoid window jams or functional failures. Consulting a repair shop for seal replacement or lubrication is cost-effective and hassle-free. After all, addressing minor abnormalities promptly helps maintain the car in good condition for daily driving.
