I have 2012 ford F-250 Super duty blowing from vents won't switch to defrost or floor. I checked for obstructions in vents as well blend door operations. I replaced control head, new blend door actuator so far. First time here learning my way around any help would be a blessing.
Thanks, John

 

Well I found a video for ya, guy has the same problem. Don't really think he's going about it the right way when he brings a crowbar into it, but hey, redneck ingenuity right?? LOLOL
