What Causes Water Under the Car Seat?
3 Answers
There may be several reasons for this: Rainwater entering through the windshield: It is possible that the windshield was not properly closed, allowing rainwater to enter during rainy weather, resulting in water under the car seat. Make sure to close the windows properly to avoid water ingress. Poor door sealing: If the rubber seals are incorrectly installed, repeated closing and squeezing of the doors can cause the seals on both sides to deform, leading to poor sealing of the car. In severe cases, this may even cause water to pour into the car during rain. Sunroof leakage: Pay attention to the waterproofing of the sunroof. The sunroof is sealed with rubber gaskets, so it is important to keep the gaskets free of dust during use, especially in winter or after long-distance travel. Regularly clean them with a duster. Additionally, never force open the sunroof when it is frozen, as this can damage the sunroof motor. Water ingress during car washing: When washing the car, avoid directing high-pressure water jets directly at the seals. This not only easily causes the seals to deform under the pressure of the high-pressure water jets, leading to water ingress, but also significantly damages the seals.
I've also encountered water under the car seat before while driving, which is usually caused by various reasons. For example, on rainy days, if the car windows aren't closed tightly, rainwater can seep in through the door gaps. Or, if there's an issue with the air conditioning system and the drainage pipe is clogged, it can cause condensation water to flow into the car. Another possibility is a spilled drink bottle, especially during long trips when kids might tip over their water cups under the seats. I remember once my old car's carpet aged and got soaked, which even led to a musty smell—it was quite troublesome to deal with. I recommend first using paper towels to absorb the water stains and checking if the air filter and door seals are intact. If the situation is severe, it's best to visit a repair shop to prevent long-term moisture from corroding the car's underbody wiring. In short, don't overlook such small issues as they might indicate hidden faults in the car.
When you find water under the seat, it's best to quickly check a few common sources first. Rainwater seepage is a major factor—inspect the door and window seals for any damage. If you frequently use the air conditioning, a clogged condensate drain pipe could also cause leaks. Additionally, don't forget to check if a water bottle you brought has leaked or if a pet has made a mess. I recommend first moving the seat aside, wiping away the water, and then using a fan to dry the affected area inside the car. If not addressed promptly, the seat foam can absorb the water, leading to a musty smell in the car and even potential rust. Regular maintenance checks of carpet gaps can help prevent such issues. Don't dismiss it as a minor problem—it affects driving comfort.
