Diamante help needed please

Hey, my 1994 Diamante keeps blowing its a/c fuse. It just started like a week ago, when I bought a new fuse, it blew that one too. I know I obviously have to much current going through there, but I am using the recommended 10 amp fuse. What could I do about fixing the problem, and would I absolutely HAVE to take it to a mechanic, or would there be some equipment I could buy, and do it myself? Please let me know. Thanks
