Why does the new car window make a squeaking sound when rolling down?

[AnnieMarie]

New car windows make a squeaking sound when rolling down due to dust, sand, or other foreign objects. Solutions for the noise issue: There may be dust, sand, or other foreign objects in the window glass track. The owner can use a cotton swab to clean the dust in the track and then apply a thin layer of lubricating grease. Spraying dashboard wax into the glass tracks on both sides and repeatedly raising and lowering the window a few times can have some effect. If the noise comes from the window regulator, you can go to a repair shop or auto beauty shop. Of course, skilled individuals can also choose DIY—remove the door trim panel, lubricate the window regulator bracket, track, and wire with grease, and then reinstall it to eliminate the noise. Check if the window film has any lifted edges; if so, trim or reapply the film. Reasons for window glass rolling noise: Aging of the glass seal strip, dirt in the gap between the glass and the seal strip, dirty glass tracks, or a faulty lifting motor.
