What Causes Water Leakage in the Front Passenger Seat?

[Dale]

The reason for water leakage in the front passenger seat is a clogged drainage hole. If the sunroof drainage hole is clogged, the blockage will be at the entrance of the drainage hole, which can be seen by opening the sunroof. At this point, it is relatively easy to clean, and you can remove the blockage yourself. The purpose of the air conditioning drainage hole is to discharge the condensation water formed during the heat exchange process of the air conditioning evaporator out of the vehicle. When water leakage is found inside the car, first check the amount of water and the size of the affected area: If the amount of water is very small and the wet area is minimal, you can wipe the water stains clean yourself, lower the windows, and if possible, open all the doors to dry the car in the sun, then place some desiccants inside the car. If it is necessary to dismantle the carpet in the driver's compartment for air drying, or if the affected area is large and requires the removal of original car parts, it is recommended to go to a 4S store for professional handling.
