Well the title says it all. Whenever it rains I've got water coming through the dash in a couple of places. It's at a dripping rate. It's enough to get my pants leg noticeably wet if I'm in the jeep for over 10 minutes or so. It makes me cautious of having stuff in the floor in the passenger seat too. It's had some electrical work done to it from a previous owner which makes me wonder if they pulled something out and never put it back? It's a 1990 model. Is this common? Any ideas?
