When I got my 1800, there was a plastic 'tape' that was hanging out in places between the dash and the windshield. One day, I pulled it out, and now the windshield sticks to the dash; must have some glue left in there. I take my w'shield and rock it back and forth, and it finally starts to move. One of these days, I will take it apart and fix that problem. Might be the same prob that you've got. :?:
