Why is there noise when the car window glass is raised or lowered?
2 Answers
The reasons for noise when the car window glass is raised or lowered are: 1. Loose fastening screws or window regulator brackets inside the window glass; 2. Aging of the window glass sealing strip; 3. Debris in the window glass guide rail. Car windows are an important part of the entire vehicle body, designed to meet the needs of interior lighting, ventilation, and the visibility of drivers and passengers. They are divided into front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. The solutions for abnormal noise when raising or lowering car window glass are: 1. Tighten the loose door glass at a professional repair shop; 2. Replace the window glass sealing strip; 3. Clean debris from the guide rails.
The car window makes noise when rolling up and down. As an experienced driver, I've seen this issue several times. It's most likely due to dust or small gravel accumulated on the guide rails, causing a clicking sound when the glass rubs against them. Another possibility is hardened rubber seals due to aging, which tends to make squeaking noises, especially in cold weather. I suggest first cleaning the door tracks yourself and applying some WD-40 lubricant to see if it eliminates the noise. If that doesn't work, the problem might be with worn-out chains or motors in the window regulator. Severe wear can lead to louder noises or even jamming. Window regulator issues usually require a professional inspection at a repair shop. Last time, I spent 200 yuan replacing the chain, which fixed the problem. The key is not to ignore these minor noises, as they can affect the window's operation speed or even cause the glass to fall out—safety comes first when driving. Developing a habit of regularly cleaning the guide rails can save you a lot on repairs, and checking the seal condition before winter is also a wise move.
