For the last year or so, I've been getting small amounts of water building up in my rear driver side quater-panel. From what I've read on the Camry forums, most people solved their problems by replacing the trunk gasket, which seemed logical considering that my car is 15 years old. I recently replaced this gasket, but the water buildup continued, so after spraying the car down thoroughly with water, I have managed to find out the location of the water leak on top of the pressure vent. BUT, even though I know where it's coming in, I'm not quite sure how to solve this problem.
