I have both a 93 SE and a 97 SSE that have sliding sunroofs. The 93'* works just fine, stops and starts, no noise. But, the 97 SSE won't stop moving until I hit the button a second time. If I forget, a real annoying ratchet sound happens like the motor is stripping gears. To get it to the tight closed position, I have to fiddle with it up and down to get it just right. So, the question is: Is it a motor problem? Or, is there something I need to adjust? For either, how difficult is it to get to the motor or the controller to adjust the stops? I found a few bonnies in the bone yard with sunroofs but would hate to start ripping off the interior roof panel to find something I don't know what I am looking for.
