2012 Ford Edge. I replaced the bda due to only hot air on the driver side. The new part didn't work so I removed it, plugged it back in to see if the arm moved at all by raising and lowering the temperature. Nothing happened. Next I plugged the old part in and it moved back and forth with the temperature change. I've heard of the need to calibrate the part but searching through the forum nothing is mentioned about a 2012 edge method of recalibrating a bda or if it is needed. This is the second new part I have tried so I am thinking I need to do something to get it to work. Both new parts can't be bad. In the mean time I have adjusted the blender door manually so I am getting by for now.
