Temperature Control

The vehicle operator can determine the temperature of the A/C air by using the temperature control. The temperature control cable opens the air mixture door to a position to divert sufficient air past the evaporator to achieve the desired vehicle temperature. Warm heater air is mixed with cool A/C air at the air mixture door. When the coldest temperature setting is selected, no warm heater air is mixed with the cool A/C air.
