My sleeper HVAC temperature control doesn't work. Checked the resistance at temp knob while turning it from cold to hot and it was good. Replaced the sleeper air door actuator new part

Does anyone know what these two pins are for? I checked the voltage and it doesn't show any. I think there could be bad wires somewhere, any ideas ? Maybe someone fixed their sleeper temp regulator already and knows the solution, please help

Look here for the pins... http://bodybuilder.navistar.com/General/BBcircuitIX.htm

I'm thinking it could be the resistor, that spike thing.
