Hey everyone! new to the forum!! the notorious climate control bug has gotten me in my 79 coupe deville.. i have no power to the big 3 ( orange, orange black, grey) wires at the back of the control module harness which doesnt give power to the blower.i can straight wire it from the battery and blower jumps in so i know thats good..not sure about the resistor being its kinda beat, but that shouldnt stop power from coming to the blower motor ...right??.....so I tested the wires back at the blower relay and see that no power comes to the orange/black wire..every other wire in the relay block gets power.. any suggestions on what I should do next?
Did you check the fuses?

Check your fusible links. One feeds the relay circuit.
