Well, if you read my earlier post about identifying what ended up being the AC Amplifier, I replaced my blower motor resistor, blower motor relay, checked that the blower motor wasn't just bound up inside the housing, ran it direct with a battery, double checked the circuit breaker, etc all without actually fixing anything.
I'm thinking next steps are just going to be tracing voltage, which probably should have been my first step, but I really do not like doing it for some reason.
In an attempt to make that easier, last night I got under the dash and proceeded to cut out the old Alpine security system that I had put on the truck in college. I started by pulling and cutting wires one at a time, starting the truck in between each cut. That really cleaned up the wiring above the pedals. One mishap, in doing this, I either finally burned out my starter solenoid, or missed my steps in between the last two wires and cut my ignition wire. (I got a little lazy on the last couple wires and pulling relay wiring.) Was able to start it by jumping the solenoid, so I know its one of those two things. I unplugged all the relays mounted to the driver's side firewall to see if anything changed either. I don't think any of them are actually being used (headlight cleaner relay and the other two there above it).
So my best guess on the AC blower is either a bad ground, or I have damaged the power wire to the blower fan somewhere. Both relays I have click so I know the problem is in between there and the motor itself.
A couple other things I know I have going: no taillights/brakelights/parking lights (headlights, reverse lights, and blinkers front and rear still work), brand new alternator doesn't seem to charge (guessing this is a ground issue as I replaced the alternator a couple weeks ago because it was doing the same thing).
Plan is to replace every ground that I can find in the engine bay and work my way back.
