This may be dumb, but it did happen to me. The 2nd fan fuse wiring
went bad, burned out on the power side. I checked it with a test light, had power, then I removed it to look at it, and it was fine. Apparrently, it was burnt and barely connected, but not where you could see. placed the fuse back in, and couldn't figure out why the fans didn't work. Happen to run a test light on it later, and no power! Pulled the fuse again, noticed that it looked fine, but came out much easier...dismantled the fuse box, noticed that the wire was burnt up to the fuse connector inside
the fuse box on the hot side of the fuse connection (about 1-1/2"). Repalced the wire, good to go. Did you check the relays and fuses by visual, or by test light? There should be power to the fan fuses with the ignition on. If not using a test light, try that. But then again, it sounds like you already may have done that...
