What Causes Water on the Car Floor?
1 Answers
Reasons for water ingress on the car floor: 1. Corrosion and perforation of the chassis: Water splashed by the wheels flows in. Inspect carefully and seal the holes or install a protective panel. 2. Clogged rainwater drainage holes in the windshield scupper: Open the hood to check and clean/unclog them. 3. Damaged or ineffective door seals causing wind-driven water ingress: Inspect and replace the seals. 4. Blocked sunroof drainage tubes: Water enters through the center pillar. Inspect and unclog the tubes. 5. Poor sealing or corrosion/loosening of certain chassis penetration screws leading to water ingress: Inspect thoroughly and seal/tighten them. Additional notes: After water enters the car floor, promptly lift all floor mats, park in a ventilated area, open all doors, and allow natural air drying. Avoid direct sunlight exposure. There is a drainage hole on the floor—ensure all water is drained from the floor surface.
