I've inspected the weatherstripping around the door opening and it looks fine. The water is definitly dripping from up under the dash. Are there any other openings directly to the outside other than the blower motor opening? The leak occurs when the car is parked during a rainstorm (as well as when driving) so it's not a "splash-in" situation. I'd rather not have to remove the seat and lay down in the car while it's raining to locate it.
