I wonder about the blower *and* the reg. . . . maybe the blower is not installed? Or the blower reg is not mounted on the blower?? That would be too funny. 
It's not a "switched ground ckt" but rather a transistor action switch. Others may be confused thinking it's a "switch". |
You know that and I know that.... but I am trying to get to the basics without getting technical on the guy.
OK??
For testing purposes, I want him to know the circuit is controlled/switched ON the GROUND side so he understsnds why the blower works when he grounds the blu wire.
I will let you take it ...
