Electronic Automatic Temperature Control System
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The electronic automatic temperature control (EATC) system operation is determined by the settings on the EATC module. The EATC system automatically maintains a selected temperature for vehicle interior comfort. The EATC system is composed of the EATC module, blower motor speed control, mode door actuator, air inlet door actuator, temperature blend door actuator, in-vehicle temperature sensor and solar radiation sensor to control the various functions.
When the EATC module is set to AUTO:
- the air distribution direction, blower motor speed and A/C compressor operation are automatically controlled based on the temperature(s) selected.
