Airflow Mode Selection

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

When an airflow mode is selected, the FCIM  determines the applicable and allowable airflow direction. The FCIM  then sends this desired airflow direction to the HVAC module using the message path described above. The HVAC module determines the actuator position that is required to deliver the correct airflow direction. While monitoring the defrost/panel/floor feedback circuit, the HVAC module drives the actuator until the feedback circuit indicates the actuator has reached its required position.
