Savana 3/4 Ton Van AWD V8-5.3L VIN T (2003)
To activate the rear auxiliary HVAC control assembly, the front auxiliary HVAC control assembly must be placed in the REAR CNTL position.
Ignition 3 voltage is sent to the auxiliary HVAC control processor. When the switch is placed in the REAR CNTL position, the voltage is grounded
through the auxiliary blower motor switch control, front auxiliary HVAC control assembly and the ground circuit to allow the rear auxiliary HVAC
control assembly to operate the auxiliary temperature actuator. Voltage delivered to the rear auxiliary HVAC control assembly on the ignition 3
voltage circuit is sent to a variable resistor. Based on the placement of the temperature switch, a varied voltage is sent to the auxiliary air temperature
actuator on the auxiliary air temperature door control circuit, and auxiliary HVAC control processor. The auxiliary air temperature actuator positions
the temperature door to divert the appropriate amount of air past the heater core in order to achieve the desired temperature.
A/C MODE - FRONT AUXILIARY HVAC CONTROL ASSEMBLY ONLY
The auxiliary temperature switch in the front auxiliary HVAC control assembly allows the vehicle operator to adjust the temperature in the rear of the
vehicle.
Power is provided to both the front auxiliary HVAC control assembly and the auxiliary air temperature actuator from the IP fuse block on the ignition
3 voltage circuit.
Voltage delivered to the front auxiliary HVAC control assembly on the ignition 3 voltage circuit is sent to a variable resistor. Based on the placement
of the temperature switch, a varied voltage is sent to the auxiliary air temperature actuator on the auxiliary air temperature door control circuit. The
auxiliary air temperature actuator positions the temperature door to divert the appropriate amount of air past the heater core in order to achieve the
desired temperature.
A/C MODE - FRONT AUXILIARY HVAC CONTROL ASSEMBLY WITH REAR AUXILIARY HVAC CONTROL ASSEMBLY
The auxiliary temperature switch in the front auxiliary HVAC control allows the vehicle operator to adjust the temperature in the rear of the vehicle.
Power is provided to both the front auxiliary HVAC control assembly and the auxiliary air temperature actuator from the IP fuse block on the ignition
3 voltage circuit.
Voltage delivered to the front auxiliary HVAC control assembly on the ignition 3 voltage circuit is sent to a variable resistor. Based on the placement
