The large pink wire that goes to the heater fan is to always have 12 volts. My heater fan pink wire tested at only 3.7 volts. The 30 amp AC fuse that is the voltage source appears to be all normal. A temporary 12 volt jumper to the pink heater fan wire led to success. The same 12 volt source, large 30 amp AC under-bonnet fuse, also supplies the climate control ECU which showed low voltage (9.6).
The large 30 amp AC under-bonnet fuse is after market. Before going with a work around inline fused wire, I am going to be certain that the 30 amp AC fuse is passing along all 12 volts.

My symptoms were no AC, no heat, blower fan inoperative at all speeds and the AC switches would not turn on. The rear defrost switch would respond, showing some power to the switch/ECU assembly.
