Temperature 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 a temperature is selected, the FCIM sends the desired temperature selection to the HVAC module using the message path described above. The HVAC module then determines the temperature blend door desired position. While monitoring the temperature blend door feedback circuit, the HVAC module drives the actuator until the feedback circuit indicates the actuator has reached its desired position.
