HVAC Module
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.
