I've read countless posts on this but can't seem to find the solution. I've replaced the lower driverside blend door near the accelerator pedal, since my controls were stuck on panel. Disconnected battery and fuse 46, replaced, reconnected and let it calibrate. The recalibrate seems odd but after turning ignition on and waiting, it just rotates to full defrost and remains there with no control. Tried it mutliple times. Made sure the actuator would be position at arrow and reinstalled.

Any ideas? Climate control works for everything else. Thought maybe it could be the BCM but would be odd that only the vent control would stop working.

 

Is this on your Lightning or something else? You posted in the 2009-2014 forum.
