I just when though this with mine... easy fix The weather seal around the top of the glass is old and I bet you have a 1/8 gap between your windshield and the frame. Just take of the Top T-Panel... easy and then unscrew the Black shield that covers the top of the windshield then the galvanized trim holder and then you will probably see the gap.. just put in new fresh bead of Window caulking and your done. Take about 30 Min to do everything Good luck... now if I can find out where my door is leaking I will be fine :) Jason
