I have 12 volts on each side of fuse.
Still no power on the orange or purple wire. I have installed new new relay,resistor and fan switch and heater AC controls.where does the orange wire get its power from?
I need some help. When I turn the key on I have no power to the fan switch or to the high speed relay except for the red wire which is constant. This is on a 1979 GMC jimmy. Can anyone point me in the right directions?
Thanks
