Left Hand Lever
The system is totally inoperative and there is no air-flow when this lever is at OFF, In the VENT position, the air selector doors are in the "outside air" position and unconditioned ram air is discharged through the instrument panel outlets. At MAX the air selector doors are in the "inside (recirc) air" position, the blower is automatically on low speed, and the compressor is running (providing the center lever is not placed at HEATER). At NORM position, the air selector doors are in "outside air" position. The blower is still automatically on low speed and the compressor is running. Moving the lever between NORM and HOT will control the temperature of discharge air.
When this lever is in any position except OFF or VENT and the ambient switch is closed, the compressor will be running (providing the center lever is anywhere except at HEATER).
