Sunroof Motor

The sunroof has a 12 volt reversible DC motor, gear train and a limit switch. When the motor is not operating both circuits are at ground potential. When the motor drives the sunroof glass in the open direction (from the vent position to the open position), the following occurs:
- Voltage is supplied to the sunroof motor feed open circuit.
- Ground is maintained to the sunroof motor feed close circuit.

When the motor drives the sunroof in the closed direction (from the open position to the vent position), the following occurs:
- Voltage is supplied to the sunroof motor feed close circuit.
- Ground is maintained to the sunroof motor feed open circuit.
