( quote) Ground the pink wire from the horn relay using a sharp probe into the relay socket. Does the relay click?

NO. I have 12V at green wires into the relay, no power at the pink or purple and when I ground the pink nothing happens.

(quote) If there's power to #44 orange and #44 black wire is grounded, the fan should work. We've only had one bad fan over the years, but that's a possibility.

I have NO power to #44. At the relay, I have 12V at the orange wires and no power at the others.
