That is most helpful John! Thanks for your help...as you can see, Dan and I are not AC guys, so we need guidance from the fantastic PY world knowledge base.
I think in AC cars the fan only runs when the top temp control slider is moved from the off position and then the master switch sends power to the blower switch. I have an extra AC controls that I saw and heard the master switch click when the temp slider was moved all the way to the off position (far left).
