Came up with another idea over night...
I got to thinking there must be a break in one of the two wires that run to the switch and that I may have disturbed it enough to have broken the circuit. I removed the passenger seat and went looking for it. Didn’t have to go far, about 2” toward the rear, under the carpet it looks like someone had tightened down a bracket right on top of the little yellow wires and crushed them badly. Seems like my fiddling with the switch dislodged one from the pinch – the pinch was clearly the cause of the ‘always on’ blower and the subsequent disconnect.
Spliced in some new wires - problem solved!
