What Causes Water Leakage Under the Front Passenger Seat?

[ArianaMarie]

Reasons for water leakage under the front passenger seat: 1. The condensation pipe above the front passenger's left foot gets cold, causing water droplets to form upon contact with air. 2. The air conditioning drain pipe is too short or has become loose and aged, causing the pipe to bend and obstruct drainage, leading to water spilling inside the car. 3. Clogged sunroof drain holes or guide pipes. 4. Aging sealing strips around the air conditioning unit or car doors. Solutions: 1. Clear the drainage holes on both sides of the engine compartment. 2. Unclog the sunroof drainage holes. 3. Secure the air conditioning pipe near the air filter. 4. Clear the drainage holes below the car doors. 5. Replace the sealing strips around the air conditioning unit and car doors.
