Yea, NAPA or Pep Boys should have them...they're only a few bucks each. They should have the same ratings, just make sure that they're 5 pin and not 4 pin (looks like the harness uses terminal 87a from the pic). Automotive relays pretty much have the terminals universally numbered...pins 85, 86, 87, 87a and 30...some don't have pin 87a.

Plugged in the relays to the harness, and still nothing. WTF. The number listed above didnt cross reference to anything NAPA had. They gave me three 5 pin relays. They are all different to cause thats all they had in stock. Im lost now. i dont know what else to do or to try. Please help!

Take a test light, and go from where you got your power for the harness to where you got your ground...if it doesn't light up, one of those connections is no good. If that checks out OK, lets try and diag the reg temp fans first. To eliminate the PCM as being the problem, you can take the wire that goes to pin 42 and ground it, and if the fans come on, then the PCM isn't doing it's job and grounding that wire. I'd remove the wire from the PCM connector to do this because grounding the PCM could let the smoke out of the box. As for the a/c issue, make sure that you're tapped into the dark green wire, not the lime green wire.
Then we'll take it from there.
