Replacing the climate control head DID fix the erratic blower motor speed though so that saves me trying to fix the erratic blower motor speed by putting in a new blower motor resistor . . .

Can someone please tell me what fused circuit feeds the hot / cold wheels on the climate control head and then sends power to the heater control valves? I've checked / double checked and triple checked every fuse that is supposed to have anything to do with the climate control (ie 15, 33, 34, 37) and all those circuits seem good. Any suggestions??
Do you actually have power at pin #2(?) on the valve connector? If you do and you should as it comes straight from the fuse then it is a grounding problem somewhere.
That is what I see with my very limited knowledge of sparky stuff. A meter between a good earth and pin #2 (?) should give a reading of 12 volts.
