How to Deal with Squeaky Car Window When Rolling Up/Down in Rain?
2 Answers
First, identify which car door's window is making the noise. After determining the problematic window, roll it up to the top and prepare the dashboard wax. Spray the dashboard wax into the gap between the window's exterior brush strip (the sealing strip on the outside of the window glass) and the glass. After spraying, roll the problematic window up and down two to three times consecutively. This should eliminate or reduce the noise. Finally, wipe off the dashboard wax from the glass with a clean cloth to prevent attracting more dust.
After driving for so many years, if the car windows squeak when rolling up or down on rainy days, it's mostly due to dust or small debris washed in by rainwater getting into the tracks. I usually find a parking spot, wait for the rain to stop, and then use an old toothbrush dipped in soapy water to carefully clean the track gaps, followed by wiping them dry with a cloth. Then, I apply some silicone-based grease or a dedicated window lubricant, spreading it evenly, and roll the window up and down a few times to distribute the lubricant. If the rubber seals are aged or cracked, feel them with your hand—if they're hard and cracked, it's time to replace them. For prevention, try to park in a garage or sheltered area to minimize water accumulation in the window gaps. If the noise persists after trying these methods, the issue might be a stuck or rusted window regulator—don't hesitate to visit a repair shop promptly to avoid further damage that could compromise driving safety. Regular maintenance shouldn't overlook cleaning around the windows; small noises are easier to fix early on, while delaying can lead to costly and frustrating repairs. The seasoned driver's advice is to address issues early for peace of mind.
