hikegnp 1/28/2013The seal on the windshield may not be intact on the passenger side. I have a 1990 Civic that has a similar problem and I pulled off the trim just below the windshield on the passenger side and could see water dripping down. I pressed the seal into the glass and the water quit coming in for a while. Since it is an old car, its just something I put up with.
