How to Deal with Squeaky Car Window When Rolling Up/Down in Rain?

[VanBlakely]

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.

I used to have the same issue—the window would squeak annoyingly every time I rolled it down on rainy days. It was probably dirt or leaf debris stuck in the tracks. I tried wiping the dust off the tracks with wet wipes, then ordered a bottle of automotive lubricant spray online, like the silicone-based WD-40, and spraying it solved the problem easily. The process is simple: just spray and roll the window up and down a few times. If the rubber seal is dry and cracked, increasing friction, replacing it isn’t expensive. For prevention, parking under a carport or in a garage can avoid water accumulation from rain. Occasional noise is normal, but frequent squeaking might indicate a window regulator issue—best to have it checked at a repair shop. DIY methods save money and time; a quick spray of lubricant works fast and keeps your daily driving mood unaffected.

As a female car owner, the annoying squeaking noise from the windows on rainy days could be due to dirt in the tracks or friction from aging rubber seals. I'd first use a soft cloth dipped in alcohol to clean the window tracks and edges, removing any grime. Then, I'd apply some specialized window lubricant spray, which is readily available at supermarkets. These noises aren't just irritating—they can accelerate part wear, so don't ignore them. For prevention, regularly check the condition of the seals during maintenance, about every six months. If the noise persists after DIY attempts, it's advisable to visit a 4S shop or consult a professional mechanic to prevent minor issues from escalating into major problems that could affect driving comfort and safety. Staying focused while driving is crucial, and window noises can be a real mood killer.
