When a fuse blows, it's usually because either a wire has shorted or the very thing that the circuit powers has failed. If memory serves, then this is a pretty simple system. I suggest getting a multi-meter and checking for a short in the wiring to the fuse box. To do that, you'll set your multi-meter on ohms (I want to say 2000 but I don't have one in front of me to be sure). Now hook the positive lead in to the box, where the fuse normally plugs in, and plug the other lead to a known ground source (preferably the negative battery terminal). The reading on your meter should be infinite, indicating no short circuit. Jiggle the positive around and make sure that its infinite. Then move the positive over to the other side of the fuse and recheck. Again, it should be infinite. Anything less suggests a short in the wiring between the battery and fuse box. Otherwise, we'll move on. I'll keep thinking this evening and come back with anything I think of.
