Electronic Automatic Temperature Control
The climate control assembly (EATC module) analyzes input from the following major sources:
- Temperature, function and blower selection (made by the vehicle occupants)
- In-vehicle temperature sensor
- Ambient temperature sensor
- Sunload sensor
- Vehicle speed sensor
- Engine coolant temperature sensor
Using these inputs, the climate control assembly determines the correct conditions for the following outputs:
- A/C clutch engagement
- Blower speed
- Temperature blend door position
- Floor/panel mode door position
- Panel/defrost mode door position
- Air inlet mode door position
