What causes the noise from car window glass while driving?

Solutions for noise from car window glass while driving: 1. Loose door screws or lifting bracket, simply tighten the loose door glass. When driving on bumpy roads, the car window glass may make noise, which is usually caused by loose fastening screws inside the window glass or the lifting bracket. 2. Aging window glass sealing strip, replace it directly. Aging door glass sealing strips are often one of the reasons for window noise. If it's a new car making noise, simply purchase lubricant and apply it evenly on the sealing strip. 3. Debris in the window glass guide rail, the solution is to use tools to clean the debris in the guide rail. The gap in the sealing strip of the car slot can easily bring in dust and particles during the glass lifting process, which may cause vibration and noise from the window glass. If dust and particles accumulate more and more, it may damage the lifting motor.
I've been driving a small car for several years, and the squeaky windows are really annoying, especially on highways or bumpy roads. The most common cause is the aging and deformation of the rubber seals around the window frame. Sun exposure and rain erosion make them hard and cracked, causing strange noises when the glass moves up and down. Additionally, dust or small stones stuck in the window glass tracks can also create rattling sounds. Last time I encountered this issue, the noise sounded like metal scraping, and it turned out to be loose screws in the window regulator. These problems should be addressed early; otherwise, they can worsen over time. Damaged seals may even lead to rainwater leakage and dust ingress. I recommend cleaning the tracks first, and if that doesn’t help, visit a repair shop. It usually doesn’t cost much but requires professional handling.
As an experienced driver, I think window noises depend on the sound. If it's a clicking noise, it's probably a stone or debris stuck in the track; if it's a buzzing sound, it might be friction between the glass and frame, often due to aging seals; and if it's a squeaking sound, it's usually rust or lack of lubrication in the window regulator. Don't overlook these small issues—wind noise at high speeds can be distracting, and if the regulator fails, the window could get stuck, which is dangerous. My advice is to regularly clean the tracks with a damp cloth and keep some lubricant spray handy for the rails. If the noise persists, have a mechanic check the motor or wiring. Older cars are more prone to these issues—safety first, after all.
