General Information

The purpose of the heater is to supply heat to the interior of the vehicle. The vehicle operator can determine the level of heat by turning the left temperature switch, located on the heater and A/C control, to any setting. The temperature control can change the vehicle's air temperature regardless of the HVAC mode setting, heater or A/C. The vehicle passenger can adjust their temperature by adjusting the right air temperature switch. Passenger temperatures can be set anywhere between 16°C (60°F) and 32°C (90°F). The dual zone temperature control system does not have any temperature limits, one zone could be full hot and the other zone can be full cold. The heater and A/C control provides power to the LH and RH temperature valve actuators through the battery positive power supply circuit. Ground is provided to the stepper motors through the control circuits. Power and ground are provided to the heater and A/C control from the fuse block, through the battery positive voltage, ignition positive voltage and ground circuit.
