Moonroof on 2000 Buick Regal is STUCK... Please Help, Motor is working
Electric Moonroof/Sunroof is stuck in the tilted up position. While pushing the buttons to open/close or slide into the roof, you can hear the motor working, but there are two arms that are connected to the tracks, that seem to have came loose. One arm is on each side of the sunroof. Finally managed to get one of the arms back out of the roof, but the other arm sounds like it has fallen somewhere in the roof, after coming off track. Definite RAIN predicted. Need help soon.

My car had same problem. Found out it has a manual override by pushing dial in or out. Can't remember that part but was able to shut and was fine after that. Hope it works.
In order to find out what's causing the problem, the headliner must be dropped (removed) to access the sunroof motor so it can be inspected and removed to inspect the slide cables up inside the sunroof/moonroof assy. Until that's done, there's not much more I can do to help except speculate.
Push and hold the moonroof switch toward 2 . Once the moonroof has reached the full tilt position, release the switch. Push and hold the switch toward the 2 position again.
The roof slides along a channel actuated by a coiled cord.
Both of the cords pass along a gear attached to the Sunroof motor which pulles the cord tooth by tooth.
There are two plastic wedges that drop into the plastic slides on the sunroof (the plastic slides are behind the more forward metal slides.)
The plastic slides control the tilt of the roof when moved independantly. The plastic wedges join them.
If the roof moves too far back, it is possible for the wedges to stick up and jam the roof open.
This should never happen, but could if the two micro switches on the sunroof motor assy fail to provide feedback to the controller indicating the roofs position.
Access to the Sunroof motor requires you to drop the headliner.
To drop the headliner, the plastic pillar shrouds need to be removed front and back, the seatbelt bolts in the middle secion need to be removed, the oh-**** handle, the front visors, and cabin lights.
3 bolts hold the motor up.
With the motor down you can try* to manually actuate the cords using a flat screwdriver, but move the left and right side evenly a tooth at a time.
Of course of the plastic wedges are jammed, it's not going to budge.
My son called a Buick dealer and they told him that it is very common for Buicks to go dead quite suddenly and completely when the battery goes out. He charged the battery and all seems to be well, so far. Still having trouble with the moonroof being stuck, but that's a separate problem apparently. Thank you.
