thanks Doug, There are 5 wires on the resistor; the hot orange, black ground and 3 smaller gauge wires of yellow, purple and brown. I had breakfast with my mechanic friend this AM and he said the smaller wires are related to the blower speeds. The fan's variable speeds are working correctly.
More info:
the blower motor stopped working a few years ago, and I pulled it out to check it. But never got back to the car until this year. My friend diagnosed the resistor as bad and I replaced it. The caveat may be I hooked the 2 small hoses that had to be unhooked to remove the blower motor up backwards? I thought I had them correct by the natural bend and fit of the hoses. Or maybe when I pulled the unit out of the dash one of the vacuum lines came loose, but I tried to be careful that didn't happen. There is a lot more going on with the hvac system than my skills can keep up with.
