What Causes Water Leakage in the Driver's Seat?

[MacLondyn]

Water leakage in the driver's seat is primarily due to drainage issues. After ruling out human factors, if water continues to drip under the driver's compartment, the vehicle's drainage system should be inspected. There are four drainage outlets in a car: the two front outlets are for the sunroof, and the two rear outlets are for the vehicle's flow drainage. Specific details are as follows: 1. Windshield Gaps: The issue may stem from improperly sealed windshields, gaps, or poorly welded metal plates beneath the wipers, leading to leaks. 2. Poor Quality Drainage Pipes: Some drainage pipes are of inferior quality, prone to aging and loosening, which can cause bends in the pipes and obstruct proper drainage. 3. Disconnected Condensate Pipes: If water leakage occurs on the passenger side while the air conditioning is on, it may be caused by a disconnected condensate pipe.
