What Causes Water Under the Driver's Seat Mat?

[DiVictoria]

The reasons for water under the driver's seat mat in the cabin are: 1. The sunroof seal is not tight, allowing water to leak from the sunroof to the area under the car mat; 2. Water from car washing was not completely cleaned out; 3. Rusting of the interior heater, causing water to leak under the car mat; 4. Aging of the car's sealing strips. The solutions for water under the driver's seat mat are: 1. Remove the car mat and clean out any remaining water inside the car; 2. Open the car doors to air out and dry; 3. Adjust the vehicle's circulation switch to internal circulation to drain vapor through the air conditioning system; 4. Replace the car mat with one that has waterproof properties; 5. Check if the sunroof's drainage pipes are clogged.
