Took it to the dealer. At first they were worried about hooking up the diagnostic machine to it with all the mods the car has, cause they thought it would wipe the PCM. Got over that hurdle, went and ran some other errands, and when I came back it was good to go. They just swapped out the fuse and didn't charge me anything. It's not under warranty and that wasn't even the dealer I got it from. My lucky day I guess. Hopefully the fuse doesn't blow again, but I'm thinking about installing a secondary fan with a switch on my dash/console so I can have a backup, and with AZ's temps that might be a good idea anyway.
