How to Solve the Problem of Noisy Car Window Glass?

Solutions for noisy car window glass: 1. Noise during the process of raising or lowering the glass: If the issue is due to a malfunctioning window regulator, it is necessary to replace the entire window regulator assembly. Another possible cause is dirt on the glass seal strip, which can cause noise during operation. In this case, clean the rubber seal strip and apply an appropriate lubricant. If the problem persists after these measures, the rubber seal strip may need to be replaced. 2. Noise from the glass during low-speed driving: This could be caused by loose fastening screws inside the dashboard or misaligned components, leading to vibration of the window glass and resulting in noise. When the engine is idling, engine vibrations can cause the entire body to shake, leading to noise from the glass. This situation may be related to improper screw tightening and installation during the manufacturer's assembly process. To completely eliminate the fault, disassembly and inspection for repair may be required.
Recently, I've been hearing a creaking sound from my car window, especially when driving on rough roads. There are usually three reasons for this: first, the window seal has aged and hardened due to prolonged exposure to sun and wind; second, there's dust or small stones stuck in the window track; third, the lubricant in the track has dried up. I've dealt with it myself by first thoroughly cleaning the seal and track with a damp towel, then applying rubber conditioner or tire wax to the seal to restore elasticity. If there's noise when rolling the window up or down, spraying WD-40 into the track for lubrication works well. If the noise persists after these steps, it might be due to loose parts in the window regulator, and you'll need to visit a repair shop to have the door panel removed and screws checked by a mechanic.
Don't panic when encountering window rattles - I've gathered some tricks from years of driving experience. First check if the rubber seals are dirty - use a toothbrush with soapy water to clean dust from the track gaps. For aged seals, buy a rubber protectant from auto parts stores (around $10) and apply it every few days to maintain elasticity. I also recommend adjusting the window tension screw (located in the small hole on the door side) - a slight turn with a screwdriver might fix it. If the noise worsens during rain, it's likely a sealing strip issue - temporarily inserting a straw in the seal groove can help. However, door structures are complex - DIY disassembly may damage clips, so professional help is advisable if problems persist.
Previously, there was a squeaking sound when I rolled my car windows up and down, so I consulted a familiar repair technician. He said the key is to identify the source of the noise. If it's coming from inside the door panel, it might be due to worn plastic spacers in the window guide channel, requiring the door panel to be removed for small part replacements. If it's a friction noise from the external sealing strip, then applying liquid silicone spray would suffice. The technician taught me a simple way to diagnose: if the noise disappears when pressing on the glass while rolling it, it's a sealing strip issue; if the noise persists even when pressing, it might be due to a deformed window regulator. They charge around two hundred for such repairs, but he advised against leaving windows open for extended periods, especially under trees where falling leaves can easily cause such noises.
