I'm pretty sure it is electro servo controlled. The climate control is touch button so, I think you are correct there Trent.
Could be a loose wire on the controller or what I mentioned previously. I can't imagine the damper motor could be faulty, more than likely the signal isn't reaching it.
If someone has been frigging around in that center dash area, may have not coupled the molex plugs properly. All it takes is for one pin to not make contact and all hell breaks loose..
Maybe I'm exaggerating, but you get my drift.
