Thanks for the feedback everyone.

I've read and been told that if the auxillary fan spins freely and runs when jumped, it is probably not the problem. The car has only one and the draw on it does not appear excessive

Which leads me to Steve's suggestion of the compressor clutch. The clutch has been making noise for some time.

Dan, thanks for fuse bypass suggestion. A buddy has a similar setup and I was trying to think of what he was using to take the temporary load, that flasher.
