How to Solve the Problem of Abnormal Noise from Car Window Glass?
2 Answers
There are mainly two situations for abnormal noise from car glass: 1. There is abnormal noise during the lifting and lowering of the glass. This is usually due to a malfunction of the glass lift itself, in which case the entire glass lift assembly needs to be replaced. Another reason could be dirt on the glass sealing strip, causing abnormal noise during the lifting and lowering process. In this case, the rubber sealing strip needs to be cleaned and lubricant should be applied appropriately. If the problem persists after treatment, the rubber sealing strip needs to be replaced. 2. If you hear a vibrating sound from the glass when the vehicle is driving at low speed, it may be due to loose fastening screws inside the dashboard or misaligned parts, causing the window glass to vibrate and produce abnormal noise. When the engine is idling, the engine vibration can cause the entire body to shake, leading to abnormal noise from the glass. This situation may be related to the manufacturer's improper tightening of screws and incorrect installation positions during assembly. To completely eliminate the fault, disassembly and inspection for repairs are required.
My old car also had window rattling issues last year, especially when driving on bumpy roads with creaking sounds. I tried several DIY methods: first thoroughly cleaned dust and debris from the window seal gaps with wet wipes, then sprayed window lubricant to restore the rubber seal's elasticity. For aged rubber parts, I applied rubber protectant and rolled the window up/down several times to let it penetrate. If that didn't work, I'd check for loose regulator screws or deformed tracks. Once I found a small stone stuck in the glass guide channel - removing it with tweezers immediately solved the noise. When all else failed, I visited the repair shop where they used a stethoscope to locate the noise source, then replaced seals or adjusted regulator brackets. Trying these methods in sequence usually solves the problem.
