Help! Just a little while ago, while out driving, my passenger went to open the sunroof. Started retracting okay for the first 6" or so; then there was a slight stall and a SNAP and the motor was still spinning but had no retraction. She let go of the switch and I pulled over to check it out. The roof slides freely and the motor still runs (I moved it back a little more but did NOT run it forward again for fear of damage or tangling something inside the roof). I pulled the roof all the way forward again and since it won't seal I've done the temporary plastic sheet/tape bit around the edges. But: summer's coming (with rain) and I'll NEED the roof. :)
QUESTION: what kind of job is it to pull the headliner? Once I get at the mechanism I can figure it'll be pretty easy to repair (it ain't rocket science) and I'm pretty tool-capable (do my own brakes, belts, filters/fluids, regular maintenance, & etc.) but this will be my first MB headliner and I'm wondering how involved it could get.
Any help/comments will be greatly appreciaated. Thanks!
