2013 Chevy Captiva. No heat

What is your question?

2013 Chevy Captiva. None of the 3 actuators for the heat/AC belnd doors work. manually moving the blend door results in heat, etc. Blower works fine, heated seats work fine. Lights on the controls work fine. Hard to imaging all 3 actuators are bad. Can't find any blown fuses (identified one in engine compartment and one under glove box to check based on labeling). I am thinking it must be the control head (knobs and switches) on the dash @ $134 but though I'd ask for another opinion 1st.
