I think what I was calling the AC fan is actually called the sub fan (the one on the passenger side). I've been reading some other stuff on the forum so that helped there.

Any way, here is what I have tried so far tonight. I think the AC relay and the sub fan relay are good. The current AC relay makes the AC pulley come on, if I take it out, no AC pulley. The sub fan and AC relay are the same. I switched them and the AC pulley still works.

I ohmed both 25amp main fan fuses (the ones in the engine compartment) and got a tone from my multimeter so I think they are good.

I tried hooking 12 vdc directly to the main fan plug and the fan did not come on. It seems like it should, but then that would mean the other fan (sub) must be bad too? I have not tried to get to the sub fan yet.

So I think this is where I am at
I have two bad fans - seems kind of unlikely
I'm incorrectly trying to apply power to the main fan - knowing me could be likely
The main fan2 relay could be bad - I don't know how to test it
The main fan relay could be bad - I don't know how to test that either.

Any thoughts? My resident mechanic (my dad) is at the EAA venture in Wisconsin right now so I'm kind of stuck.
