Where Does the Water Leakage from the Co-Driver's Floor Mat Come From?

[Myra]

Water leakage under the co-driver's floor mat could originate from the following sources: 1. Leakage from the cabin floor drain plug; 2. Leakage from the sunroof drainage pipe; 3. Leakage from the door; 4. Leakage of antifreeze from the heater core; 5. Damage or improper installation of the air conditioning drainage pipe; 6. Sunroof leakage due to poor sealing; 7. Corrosion leakage from the interior heater. Here are the solutions: 1. Check the drainage outlets: Inspect the drainage holes of the sunroof, doors, and air conditioning for blockages. If blocked, clean them thoroughly and drain the accumulated water; 2. Check the sealing: Examine the sealing rubber rings and strips of the sunroof and doors for deformation or aging. If found, replace the rubber components.
