Alignment of Runners and Motor

If, following maintenance interventions, the coupling must be restored between the rack and the motor the system must be first set in a certain position.

After disconnecting the glass roof and the motor, though maintaining the electrical connection, the runners (2) must be manually moved to the rear part and then returned to the front part until the slot (1) and the abutting surface (3) of the guide pin are perfectly aligned.

Activate the electric motor (4) until the pin (5) of the microswitch is engaged in the hollow (6) of the plastic wheel (7).

Starting from this position the electric motor and sunroof can be refitted.
