Ok, my Assembly manual doesn't have a wiring diagram. As I'm putting things back together, the blower fan won't come on.
I've got 12 volts from the primary power supply (red wire) to the fan relay, the purple wire runs from the relay to the blower, so that is obviously the wire that supplies the final voltage to the fan. I'm assuming the other wire that runs to the relay comes from the fan speed switch, and is what controls the fan coming on and the speed.
I'm not getting any power to the relay from that orange wire. The speed select is just that, to adjust speed, so when I move the lever from Off to Heat, something needs to trigger the power to feed to the switch and on to the relay. Where is that switch? On top of the control panel. Does this same switch activate the fan for both heat and A/C?
I'm not interested in the A/C operation, as I've converted the firewall hardware to an A/C Delete assembly, so I'll only have heat.
