Realized my issue with the heater fan was that it previously had a ground on the ac compressor. I’ve ditched that fat pig, probably weighs 30 lbs.
So by scavenging the wires and swapping the ground, I was able to restore power to the two slowest fan speeds . For some odd reason the fan has a dedicated power wire just for the high speed, and there is some issue I am having with continuity, so at least I know where the problem lies.
Most importantly, my defroster “works” so that’s an inspection item done. I also forgot to show you guys my new dip stick:
