General Description

The air temperature controls are divided into three primary areas:
1. Heater Mode is related to how the heater system responds when a heater mode is selected, and how the HVAC system provides the desired temperature for each setting.
2. A/C Mode is related to how the A/C system responds when an A/C mode is selected by the vehicle operator, and how the HVAC system provides the desired temperature for each setting.
3. A/C Cycle describes the complete A/C cycle.
