have you tried pushing it to help it move?
Could be jammed, or the motor is tired.
Mine died like that last year... needed a motor. It was fine one day, then it did what it wanted!
Rigmaster here sent me a used that did the job!
If you pop the panel down, there is a spot for the allen key to go in, so you can crank it open or closed wheile you wait for a fix.
The key should be in the tool kit in the trunk
