In my '94, the heat insulation under the carpet had a foil layer that seemed glued to the metal floor. In my frustration, I pulled it all out rather than dry it, figuring it may get wet again. Well, it did, and the second time I removed the gray insulation "stuff" that is glued to the bottom of the carpet. Now the only thing that can get wet is the carpet that you see (at least no one can notice what's been removed.) I also slit the carpet so I can get it in and out from around the seat feet without having to remove seats. Then the car dries rather quickly.
I think it's all due to the funny shaped rubber piece - it's at the base of the window, forward side of the door, outside half is glued to the body, inside contacts the base of the windshield post. Some day I'll win this battle...
