3)Remove the HVAC control unit. Use a volt meter and measure voltage between ground, and terminal C12 with the key in the RUN position. It will be an orange wire. You should see battery voltage there.
4)Use a volt meter and measure voltage between ground, and terminal C6 with the key in the RUN position. It will be a brown wire. You should see battery voltage there.

Post back with the results or questions.

I remove the hvac and did the tests you suggested and the results were what you said they should be. The C12 was a constant batt voltage while C6 was batt voltage with ignition in run. I also found batt voltage at other wires while in run. I was able to identify the ground wires as well as the 5v line. It definately seems like the ccc module is the problem but I cannot afford the $480 for a new one that cannot be returned if it doesnt work. Is there some way to rig up the wires so I can turn on the fan and start the antifreeze flowing through the heater core (thats all I need) or know where I can get the wiring diagram for the computer climate control.
