Microswitches on the motor need to be re-adjusted, something has slipped.

The closed position is set by swtiches in the motor, the full open and full tilt are set by the switches in the motor.

If the motor runs but the roof panel doesn't move, check for proper lube and then for broken lift angles -- the translation bridge will cock and jam if one of the lift angles is broken or bent.

If that won't cure it, either the cable is bad or hte motor itself is screwed up.
