What Causes Water Leakage in Front of the Passenger Seat?

[Adelyn]

It may be caused by door leakage or improper adhesion of the door waterproof membrane. The specific solutions are as follows: Sunroof Drain Hole Clogged: The initial clogging of the sunroof drain hole occurs at the entrance of the drain hole, which can be seen by opening the sunroof. At this point, it can be cleaned. Water Accumulation Inside the Door: When opening or closing the door, or while driving, a noticeable sound of water can be heard. This is caused by water sloshing inside the door. Use a thin wire or small screwdriver to unclog the drain hole. Air Conditioner Drain Hole: When the air conditioner is on, observe where water is dripping continuously. The air conditioner drain hole is located there. If it becomes clogged, the water from the air conditioner cannot drain and will flow back into the cabin, usually first noticed on the floor of the passenger seat. This should be addressed promptly to prevent the carpet from getting wet and developing mold.
