EATC Module

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The dual-zone EATC module:

is located in the instrument panel.
has a vacuum fluorescent display for displaying set temperature, airflow direction, blower speed and diagnostic trouble codes (DTCs).
utilizes an on-board diagnostic (OBD) feature to supply the technician with DTCs. These DTCs direct the technician to the inoperative component.
