Electronic Automatic Temperature Control System
WARNING: This page is about a different car, the 2005 Ford Pickup. 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, 3 mode door actuators, temperature blend door actuator, in-car 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.
The EATC module manual override settings:
- Allow the air distribution direction to be manually selected.
- Allow the blower motor speed to be manually selected.
- Allow RECIRCULATION mode to be manually selected in all modes except DEFROST. When RECIRCULATION mode is selected in FLOOR/DEFROST, A/C compressor operation is automatically requested (A/C request indicator does not illuminate).
- Allow A/C compressor operation to be manually selected except in FLOOR/DEFROST and DEFROST.
The EATC module also includes:
- A rear window defrost button. For additional information, refer to BODY SYSTEM - GENERAL INFORMATION .
- Heated seat controls. For additional information, refer to SEATING .
