I searched but saw nothing quite like this. 87 300SDL

It has been working fine until today, I tried to open it but it would not go, so I tilted the rear up and that function worked ok, I tried closing it again hoping it would slide back so after tilting and closing a few times to try to get it to slide back it ceased to work at all. When it worked it was a little sluggish but did ok, I dont believe it to be gummed up as I just libricated it a couple weeks ago.

Thankfuly its in a closed position. I can hear the motor working and I can see the back of the sunroof rising and falling ever so slightly as I attempt to operate it. Looking on the outside of the car it would appear that the drivers side rear corner of of the sunroof panel is jammed slightly downward somehow. Any thoughts on how to correct this?

Thanks in advance.

Tony
