Auxiliary HVAC Control Assembly-without Sunroof Option

Utility vehicles, without the sunroof option, have both a front auxiliary HVAC control assembly along with a rear auxiliary HVAC control assembly. Power is delivered from the auxiliary blower motor resistor assembly on the auxiliary blower motor speed control circuits to the rear auxiliary HVAC control assembly. If the vehicle operator places the front auxiliary HVAC control assembly in the REAR CNTL position only, ground is provided on the auxiliary HVAC switch supply voltage circuit to the front auxiliary HVAC control assembly. Ground is routed through the front auxiliary HVAC control assembly, back through the rear auxiliary HVAC control assembly on the ground circuits and a splice pack to ground.

When the vehicle operator turns the auxiliary HVAC control switch front to the Low, Med, or High positions, power passes through the rear auxiliary HVAC control assembly and the front auxiliary HVAC control assembly controls the ground. When power is delivered to the rear auxiliary HVAC control assembly, an internal splice within the switch routes the power back out to the front auxiliary HVAC control assembly on the auxiliary blower motor speed control circuits. Ground is routed back through the rear auxiliary HVAC control assembly on the ground circuits and a splice pack to ground.
