Posted: Thu Jul 20, 2006 5:56 pm Post subject: '74 AC wiring
I am having trouble finding the wire that feeds 12v to the AC panel and the blower. I have the four seasons AC wiring diagram, but it is a little different. I don't have power to the heater blower switch, but when I connect 12v to the Brown wire (combined with a pink wire that is connected to 2 yellow wires that feed through the firewall and one goes to the heater blower resistor, and one goes to a sensor on the back of the right hand head, and the other side of the sensor goes into a wiring harness and I can't find it. Can anyone tell me where the AC panel is supposed to get power, or is there a wiring diagram for the '74 AC panel, and not the 4 seasons one?
Thanks,
Jim
