I have a 2003 Toyota Corolla Verso, which has two sunroofs. Following the recent heavy rain, both front and rear footwells on the passenger side were wet (the vehicle was parked on the road with minimal camber, but rain would run to passenger side).

There are no leaks around the roof lining and door seals are intact. A friend suggested a leak in the front footwell couldn't pass to the rear footwell, and vice versa due to the floorpan construction, so it would seem that I have two separate leaks into the car. Is this true?

I think the sunroof drains are blocked, and with there being two glass panels, this could explain both footwells being wet?
