Ok, here's the scoop:
* Doesn't work at any speed.
* Blower works when 12v applied directly to it
* Blower motor resistor pack "looks" ok...just like the pictures that other guy posted today...but I got a new one anyway and will stick it in...only $13.
* No melting or other weirdness around any of the connectors and there is a direct path with continuety ONLY in the proper wire from the switch to the resistor pack connection...I think these two are just either end of the four wire set.
* Fuses, relays, everything looks ok.
* Might as well replace the switch too, since that's out now. Any idea of how this thing is wired...what blades should be connected at what fan speeds?
Don't know what to do next (except get a new control switch). But since I've got the center part of the dashboard apart, I might as well replace the light bulbs for the hvac panel...they'll probably burn out as soon as I put it all back together.
