i found out last night that when it rains heavily, my rear driver's side takes on water. all of my catalogues for school were completely soaked. i identified that it is probably comming in along one of the seams for the rear windshield and trickling down along the side of the backseat. none of the trim is wet though.
has anyone else had this problem?

 

have somebody sit in the back and look around while you hose down the car.
