Blower motor resistor wiring help?

Get out your ohmeter. ID and mark the blower and power (feeding the switch) leads.

The resistor to switch leads should be open that is they only go from resistor to switch, so with these unhooked at both ends they should show no continuity to anything else, or ground.

I'd wire it up with "clip leads" and mark what is hi, med, low using the motor, resistor, and battery.

This is a "wish I was there" thing
