Air Distribution-Manual Auxiliary HVAC Control

If the vehicle has a sunroof (CF5), then the auxiliary mode actuator can only be controlled by the front auxiliary HVAC control assembly. The primary HVAC control module located in the dash cannot control the auxiliary HVAC system. The vehicle operator determines the mode setting by placing a mode switch in a desired mode position. Only upper and lower vent positions are available at the rear of the vehicle. When a mode setting is selected, a signal is sent from the front auxiliary control assembly to the mode actuator through the mode door control circuit. The auxiliary mode actuator moves the auxiliary mode door to the desired position. Power and ground is supplied to the mode actuator by the ignition and ground circuits.
