HVAC Module
WARNING: This page is about a different car, the 2009 Mercury Mountaineer, 2009 Ford Explorer Sport Trac, and 2009 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If installing a new HVAC module, the new module must be configured for the vehicle. Refer to MODULE CONFIGURATION
article.
The HVAC module has a vacuum fluorescent display for displaying set temperature, airflow direction, blower speed and DTCs. The HVAC module utilizes an on-board diagnostic (OBD) feature to supply the technician with DTCs. These DTCs help direct the technician to the inoperative component.
