Aaron, does the fuse blow every time the fan activates. Not sure on your car, but a 25 amp fuse is pretty hefty. Although the control circuit should have at least one relay, if that's baked, then it wouldn't work at all. The fuse is protecting the secondary side of the relay-power circuit. It's possible your fan is drawing too much current when it starts up. All the items you mention are high current systems. I would be surprised if they were all on the same circuit. Try and find out exactly what is on that 25 amp circuit. The blower thing sounds unrelated, even if the climate control system is funky. I think that it's a pretty safe bet if all that stuff comes on at once, 25 amps is about half what you might need to get past the startup current draw. Good luck..
