I would start by eliminating possible sources of the problem. I like to start with the easiest, disconnect the compressor clutch under the hood and see if it still pops the fuse, just running on the blower, if it does then it's likely something failing in the blower motor. If the fuse doesn't blow, the problem is likely the compressor. My first suspect is the windings in the compressor clutch shorting out.
It's also possible one of the wires has compromised insulation and is shorting out. More difficult to trace, lets you find out what kind of contortionist you could be.
