Two weeks ago, after having been driving in the rain for several hours I noticed water(soaked) in my passenger floorboard. I had a mechanic check the air conditioning drain to see if it was obstructed and it wasn't. Having read a lot of the post on this forum discussing sunroof leaks, I assumed that might be my problem and left the vehicle in the garage for over a week. I just drove it about thirty minutes and the passenger floorboard is soaked again. It hasn't rained at all today. The water is a little warm (it was warm the first time too). Could the heater be causing this? Anyone have any ideas?
