wet floor/ rubber seals on undercarriage

Asked by Apr 01, 2014 at 01:55 PM about the Scion xB

Question type: Maintenance & Repair

I'm stumped. I have about an inch of water where the driver's feet touch the floor whenever it rains. I thought the windshield was leaking. I put newspaper all over the driver's side at different levels, taped from the dash to the window, seat to steering wheel. On the floor, I put one up under the gas pedal and one on the floor where the driver's feet touch the floor. Everything was dry except the floor. The water was coming up from the floor (I think). I have a hole in the carpet there because of water. This has been a problem now for 6 months but it's gotten worse. I looked under the car and there are little (1") round rubber seals. I don't know if these are the source of the leaks. What are these seals for and does anyone know what the possible source is for the leaks? I'm afraid the constant moisture will cause rusting in the floor. It's a 2004 Scion xB. Thanks to anyone who can help.

Check the weatherstripping around the door. Best way to find these leaks is to pick a dry day and sit in the car. Have someone squirt water from a hose onto the car, inside all the cracks of the door and look for moisture. Also check your AC drain, it might be blocked. The round plugs on the floorboard should be the source if they are intact.
