Add me to the list - 2010 R/T - sunroof stuck in the vent position. Would move a little up, but not down, with each push. Would not close/open.
Luckily, I had long ago seen this thread and "subscribed" to it, so referencing the information from all the earlier posts was a snap! I stood ready to pull fus #44 in the trunk but first went back out to the car after some down time (obviously I tried repeatedly to close/open when it first happened - restarting the car - you name it). Initially it did nothing. I opened the door, closed it, put the key in accessory mode and it moved down a little. I did the same again - slamming the door this time, key back to accessory mode and I'll be damned if it didn't work perfectly - no matter which function I called for, it worked like new.
You can bet I'll bring this up to my dealer - first I need to find one I trust. Last experience was not a good one!
