What are the causes of abnormal noise at the door glass?
3 Answers
Abnormal noise at the door glass is a common issue in many vehicles. The causes of door glass noise are as follows: 1. The door glass rubber guide rail is too dirty or has foreign objects: Dust can accumulate in the door glass guide rail, causing noise when the glass is raised or lowered. In this case, cleaning is required. 2. Aging of the door glass rubber guide rail: When the rubber guide rail ages, you will hear the noise of the aged rubber scraping against the glass when raising or lowering the window. In this situation, a rubber protectant can be used to temporarily restore some elasticity to the rubber and reduce the noise caused by friction against the glass, or the glass rubber guide rail can be replaced.
There are several reasons I've considered for the abnormal noise at the door glass. The most common issue is a malfunctioning window regulator - when the gears or steel cables in the sliding rail wear out or age, it produces clicking or squeaking sounds during operation. Another possibility is deformed or hardened door seal strips; over time, material degradation causes friction noise with the glass, especially noticeable in cold weather. Loose door frame or fastener screws could also be the culprit, allowing excessive glass movement that creates obvious sounds during opening/closing. Dust and sand particles entering door gaps can get stuck in the tracks, causing abnormal noises too. I've encountered such situations where minor issues accumulate - I recommend regular cleaning of door edges and professional inspection of regulators or seal replacement at authorized repair shops when necessary, before the noise affects safety. Trying simple DIY cleaning first can save both money and hassle.
I often notice squeaking noises from the car door windows while driving, which is quite annoying. It's mostly due to aging or dust-covered sealing strips rubbing against the glass. It could also be caused by loose clips or an unaligned window regulator track, amplifying the friction noise. Once, after a long-distance trip, the noise became louder, but cleaning the door gaps and removing debris significantly reduced the issue. Although minor, such noises shouldn't be ignored. Remind the mechanic during regular maintenance to check the sealing strips and window regulator components—replacing them isn't expensive. Keeping windows closed while driving also helps reduce dust ingress and maintains quietness.
