What Causes Water Leakage in the Car's Front Passenger Seat?

[DanielaDella]

Sunroof drain hole blockage, aging sunroof sealing rubber ring, clogged air conditioning drain hole, and poor door sealing can all lead to water leakage in the car's front passenger seat. Sunroof drain hole blockage: During rainy days, if the sunroof drain hole is blocked, rainwater cannot drain out and will seep into the car. Aging sunroof sealing rubber ring: Plastic components harden and age over time. Once the sunroof's rubber ring ages, its sealing performance decreases, leading to water leakage during rain. Clogged air conditioning drain hole: Condensation water produced by the evaporator cannot drain out and will seep from the front passenger seat area. Poor door sealing: Incorrect installation or aging and deformation of the door seals can reduce the car's sealing performance, causing water to enter the car during rain. Solutions for water leakage in the car's front passenger seat: For a blocked sunroof drain hole, the drain pipe needs to be cleared or replaced. An aging sunroof sealing rubber ring should be replaced promptly. A clogged air conditioning drain pipe requires cleaning or replacement. Poor door sealing necessitates reinstallation of the sealing strips.
