I have a 2012 fx4 f150 with dual zone climate control. The passenger side works fine but the drivers side was stuck on hot so i went ahead and changed the blend door actuator.. I figured since it's apart I might as well change both upper and lower actuators.. I put it back together test it out and now the drivers side is stuck on ambient or cold.. I am thinking that it could be the temperature control module in that center bezel.. anyone have any experience with this?

ALSO in all the chaos of taking a million peices I was looking at the back of the temperature control module and noticed a small spot where it looks like a wire clips in does anyone know what clips in to this?

 

This is the spot where it looks to be a wire goes that i cant find

 

This is my heater controls
