No power to blower motor.

I’ve read several threads trying to diagnose my issue with no success. I can’t get power to the purple motor feed. 72K20 with factory AC.
I’ve got power to the switch, the relay clicks when I switch it off of high speed, I’ve got power to the blue wire at the relay and the small orange stand alone wire on the relay.
I’ve got power to the double yellow wires on the resistor.
All of this and I’ve got no power to the blower motor as verified with a multi meter and test light both (grounded to the negative batter terminal) on the purple motor feed wire.
Is my resistor bad and relay both bad?? I’m pretty good with electrical stuff but I can’t seem to make heads or tales of this.
Any suggestions?
