EATC Module (Climate Control Assembly)
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 EATC module provides an interface for the vehicle occupants to control the climate control system, or automatically controls the climate control system in the AUTO mode. The EATC module has a vacuum fluorescent display for displaying set temperature, airflow direction, blower speed and diagnostic trouble codes (DTCs). An on-board diagnostic (OBD) feature is incorporated to supply the technician with diagnostic trouble codes (DTCs). These DTCs help direct the technician to the inoperative component.
The EATC module display will switch between Celsius and Fahrenheit when the instrument cluster display is toggled.
