Air Distribution

The HVAC control assembly commands the mode actuator to onto of the following positions:
- Defrost
- Bi-Level
- Defog
- Floor
- Panel

The mode actuator moves the mode door through a series of linkages. The mode door diverts air flow to the appropriate ducts based upon the control assembly output. When the control circuit has a value of 12 volts, the actuator moves the mode door to the defrost position. A Value of 0 volts results in the mode door being moved to the panel position. Recirculation is not available when either defog or defrost modes are selected.
