Why is there water under the car seat?
2 Answers
The reasons for water under the car seat are as follows: 1. Rainwater entering through the windshield: It's possible that the windshield wasn't properly closed, allowing rainwater to enter during rainy weather, resulting in water under the seat. Make sure to close the windows properly to prevent water ingress. 2. Poor door sealing: If the rubber seals are improperly installed, repeated closing and compression of the doors can cause the seals on both sides to deform, leading to poor sealing. In severe cases, this may even cause water to enter the car during rain. 3. Sunroof leakage: The sunroof is sealed with rubber gaskets. During use, pay attention to keeping the gaskets free of dust, especially in winter or after long trips. Regularly clean them with a duster. Additionally, never force open the sunroof when it's frozen, as this can damage the sunroof motor. 4. Water ingress during car washing: When washing the car, avoid directing high-pressure water jets straight at the seals. This not only can deform the seals under the pressure, allowing water to enter the car, but also significantly damage the seals.
As someone who drives frequently, I find that water under the car seat is actually quite common. The most likely cause is a leak in the air conditioning system. When the AC is running, it produces condensation. If the drain pipe is clogged or improperly positioned, the water can't flow into the chassis and instead accumulates inside the cabin, especially when using the AC on rainy days. Another possibility is aging seals on the car doors, windows, or sunroof, allowing rainwater to seep through the gaps. If the water has a sweet smell or color, be cautious—it could indicate a cracked heater core leaking antifreeze, which is toxic and must be addressed immediately. Water soaking the floor not only affects the electrical circuits for seat adjustments but can also lead to rust and corrosion of parts, creating odors and safety hazards over time. I recommend first using a dry towel or vacuum to remove the water, then airing out the car with open windows or a fan. If the source is unclear or the issue persists, visit a professional shop to inspect and replace seals or clean the drain pipe—don't ignore it and risk worsening the problem. Regular maintenance of the AC and seals is a good habit that can save you a lot of trouble.
