I have a 96 Sunfire GT on it's second sunroof assembly. Both have had the same exact issue. When i open it, both sides will vent properly, but when i try to open it further, the driver side operates normally, but the passenger side doesn't move. The glass then matchboxes inside the roof, and gets stuck, forcing me to leave it either vented or closed. When i got the second assembly (junkyard find, last summer, glass+motor+frame), it operated totally normally through the summer. Didn't drive it much over winter (and sure as hell didn't use the sunroof lol) then i tried opening it this spring when i got back from school and it's giving me the same hassle. Any and all ideas welcome.
