Function Selector Switch

[07XLT4x2v8]

I've searched for answers but I'm still confused.

My story:
07 Explorer 2WD manual climate control
Stuck on blowing air our defroster only
A/C works - Max A/C works
Temp selector works
Fan speed works
When you put the function switch to off it goes off like it should

The problem is its stuck blowing out the defroster and does not switch to floor or front

Any ideas?
Function selector switch or function selector vacuum valve?

your climate control knob or actuator is stuck, broken or otherwise damaged. Could be a vacuum control involved I know specifically for your vehicle setup. But that how they work.
