How to Deal with Water Seeping into Window Gaps?

If only rainwater gets inside the car, it's not a big issue. Simply open the windows fully on a sunny day to allow thorough drying. Rain can easily bring dirt and mud into the car. On sunny days, the first step should be to remove and dry-clean detachable interior items like floor mats and seat covers.

Last time, water seeped into my car window gap and caused me a lot of trouble. After washing the car, I found the floor mats soaking wet. I immediately used a dry towel to wipe along the window frame vigorously, but water kept seeping out. Later, I specifically went to an auto repair shop. The mechanic said this kind of issue is mostly due to aging sealing strips, especially for cars that have been used for five or six years or more. He taught me to regularly clean the gaps around the window frame and avoid letting leaves or sand get stuck in the rubber strips, as this accelerates aging. Now, every time I wash the car, I make sure the workers dry the sealing strip area thoroughly. I also bought a window waterproof seal spray online and apply it once a month. Additionally, the drainage holes at the bottom of the doors need to be cleaned regularly. Once, I found them clogged and used a thin wire to poke out a pile of mud. Water seepage in car windows is not something to take lightly. Over time, it can cause rust inside the door, not to mention that repairing electric windows can be very expensive.

I've got experience with water leaking into car windows. My car is parked in an open space in an old residential area, and it's particularly annoying during the rainy season. The first time it happened, water leaked into the door panel, and the mechanic had to remove the interior door panel, only to find the soundproofing foam completely soaked. Prevention is key now. After rain or car washes, I immediately use a squeegee to wipe the window seams, especially around the sunroof and window corners. Maintaining the sealing strips is also crucial. I apply rubber conditioner every three months to keep the strips elastic. If water has already gotten in, park the car on a slope with the front facing downward and open the doors for ventilation to help the water drain quickly. For severe water accumulation, it's best to remove the seats and dry the carpets, otherwise, the musty smell is hard to eliminate. Also, try not to park under trees as leaves can clog the drainage holes, which is even more troublesome.

Water entering car windows may seem like a minor issue, but improper handling can lead to major problems. Last month, my neighbor ignored water seepage in their car window, and when the door panel was removed, they found the window lift motor completely rusted through, costing over 800 yuan to replace. If water gets in, act immediately: first, use a dry towel to soak up as much visible water as possible, then repeatedly roll the window up and down to scrape off residual water from the seals. Pay special attention to the drainage holes at the bottom edge of the door, located at the very bottom of the door panel—just clear them with a toothpick or wire. If water keeps getting in frequently, it's likely the seals are worn out; you can buy matching ones online for around a hundred yuan, and replacing them yourself isn't too difficult. Also, check the sunroof—branches stuck in the tracks can block drainage. Remember to take a short drive after each car wash; higher speeds help dry out any trapped water in the layers.
