What is the reason for the glass sound when closing the door with the window rolled down?
4 Answers
The reason for the glass sound when closing the door with the window rolled down is due to faults in the lifting motor, aging of the glass sealing strip, or foreign objects in the glass guide rail. The following is relevant information about the automatic window closer: 1. Introduction: The car window lifter automatically closes the windows for the owner when they forget to do so upon exiting the vehicle, also known as an automatic window lifter, to prevent forgetful owners from damaging their cars or theft due to open windows. The window lifter is also referred to as a window closer, car automatic window closer, car window lifter, or car automatic window lifter. 2. Function: This product features a user-friendly design, intelligently detects the original car status, automatically checks if the glass is fully raised, and employs a secondary detection mode. The window lifting system will close any improperly closed windows to prevent vehicle flooding or loss of property.
I've been driving for decades, and it's quite common for the window glass to rattle when closing the door with the window rolled down. This mainly happens because the glass isn't fully raised to the top, or the window regulator mechanism has aged and become loose. The strong vibration from slamming the door causes the glass to shake and make noise. Additionally, worn guide rails or deformed seals can also make the glass unstable. This issue tends to occur more often in humid or dusty conditions. I usually recommend closing the door gently without too much force to reduce the noise. Regularly lubricating the window regulator system—such as applying silicone grease to the tracks—can help prevent wear. For a permanent fix, it's necessary to check the window regulator screws and the condition of the guide rails, replacing parts if needed. If ignored for too long, it could damage internal door components and increase repair costs, so I always address it as soon as possible.
I enjoy doing minor car repairs myself. The main reasons for rattling windows when closing the door are usually loose or dirty window tracks. Excessive gap in the tracks or dust accumulation can cause window wobbling, and worn regulator gears may also contribute. Additionally, hardened or aged weatherstripping can fail to hold the glass properly. I typically use lubricant spray to clean the tracks, which works well and significantly reduces noise. If the issue persists, check for loose screws in the door frame and tighten them. Be careful not to let water or debris enter the track channels, as this accelerates wear. Replacing weatherstripping isn't difficult either - just buy the compatible model online and install it yourself. Overall, this is a common minor issue that DIY repair can save you a lot of trouble.
My car sometimes does this too, the window rattles when closing the door with it rolled down. Asked someone who knows cars, they said it's mainly because there's space after the window is lowered, causing noise when vibrating. Common reasons include loose regulator slots or deformed seals. Keeping the tracks clean daily to prevent dust buildup can reduce occurrences. Replacing the seals or lubricating the window regulator mechanism is effective. If the noise gets louder, check the window regulator system's mounting. Simple fixes will do.
