When the switch control lever is turned in a rotational direction, the appropriate switch contacts and signal circuits for the selected mode are simultaneously opened and/or closed to ground in order to provide the appropriate combination of voltage signals to the sunroof motor/actuator. The sunroof switch, which is also grounded to G302, is a rotary style switch. The sunroof motor/actuator supplies voltage to the sunroof switch through three internal resistors and three hard wire circuits. The sunroof motor/actuator is grounded through splice S403 to body ground G302. Whenever the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the motor/actuator is also supplied battery positive voltage through the accessory voltage circuit and the 10-amp ROOF/HEAT SEAT fuse which is located in the body control module (BCM). ![]() The sunroof motor/actuator assembly also contains the sunroof electronic control module and the two components are serviced together as a unit.īattery positive voltage is supplied to the motor/actuator at all times through the 25-amp LAMELLA ROOF fuse located in the rear fuse block. The sunroof motor/actuator assembly is located at the rear of the passenger compartment, above the rear view window, between the headliner and the roof structure.
