Thanks Guys,
Problem solved...well sort of. When I first started troubleshooting, I saw the 30A fuse on the fuseblock designated for the fans was melting but not blown. After I installed the relay at the ignition switch, I replaced that fuse with a 25A. Yesterday, I just decided to replace it with a new 30A and viola, the fans worked, although I didn't go for a road test. This tells me there's something screwy with this circuit...and the fuse isn't doing what it's supposed to do.
Any ideas?
