Help! Overheating....

My fans work just like you described...they only come on high with the ac on, and one comes on high with the ac on and the low fans off (hasn't reached fan on temp). You could wire a second toggle switch in to the high fan wire to have manual high fan operation (I'm thinking of doing this myself). Just be sure to put a diode in the circuit to avoid activating the a/c compressor when you hit the switch since it's a 12v source instead of ground.

I just wanna ensure that I get as much (if any) "crud" that might be building up before I drain. Not going to be run more than 100 miles after I add it. That's why I said...

I hope to be "Ridin' Dirty" before November!

you are overheating because of your electirc set up, what should be happening, a/c on and toggle on both HIGH it would be pointless to have 2, 2speed fans when you couldnt get the maximum potential out of both of them at the same time.... i have one of whit1's harnesses with a toggle....
toggle off, a/c off- both off
toggle on, a.c off-both low
toggle off, a/c on-one high
toggle on, a/c on-both high
toggle off, a/c off- both off
toggle on, a.c off-both low
toggle off, a/c on-one high
toggle on, a/c on-both high

I appreciate all of the responses! What should I do? Try to drive down to Futral tomorrow and see if I can get it hooked up to the pcm (4-5 hour drive) or is something wrong with the harness?

Swap your relays around and see if the behavior of the fans change. If so, go to Napa and get yourself another good relay (stay away from the cheapo ones that Checker and AutoZone sell) and replace the bad one. Make sure you look for a 40amp relay. If you have a bad one, you'll be able to tell because it will look like some of the plastic right around where the contact goes into the relay is melted.

If I was to overnite my pcm to futral and pay to have the pcm turned on and hook up the wire to the pcm, would this turn both fans on high when it gets hot with the nelson fan harness? Would this solve my problem? What about a bigger radiator? Could I still run the same fans? This is driving me crazy!
