Sounds like something to do with the Blend door acuator maybe

Welcome to the place. So the blower works in all speeds and it will blow out the defrost, the vents and the floor? Just can't control the temperature setting? There is no A/c and or no Heat available? Is this correct?

Yes it blows everywhere feet, defrost i can change where and it works fine. Just can’t adj to hot or cold stays the same?

Are you able to physically change the temperature settings on the screen (you have nav?). Have you opened the hood and seen the A/C compressor engage the clutch and stay engaged while trying to cool the truck?

Yes mine had the screen with the nav, and no I haven’t tried that it! It wasn’t working the resistor was bad but before I changed the resistor it was blowing cool air but very low and only when the truck was running?

I think I read that wrong. Probably not the door motor.

Definately check to see it the clutch engages

You can try disconnecting your battery for a few minutes and see if that allows it to reset, otherwise you may need a scanner to see what’s going on. Maybe @FordTechOne has ideas?

If the temperature won’t adjust, there are probably DTCs in the HVAC module. I’d recommend getting ForScan so you can pull DTCs; otherwise we are just guessing.
