My aux fan does not run at all when the a/c is on, nor does it run if I bridge the connection of the aux fan switch for either the low or high speed fan settings.
Fuses 25 and 29, which are the fuses for the high and low fan settings, are both good. Also both respective relays for the high and low settings work (you can here it click) when I bridge the fan switch. Also, the fan spins freely and smoothly when turned by hand.

Apparently there is a resistor for the fan that can go bad, but I have no idea what it looks like or where it's located, also I've read that it only causes the low speed setting to fail, but my fan doesn't work on high or low.

The resistor is on the auxfan wiring harness. Lokk for the metal heatsink, it's about 2' long and 1/2' dia. Somebody here from the 21st century ought to be able to post a picture.
