AC fuse keeps blowing

I have a 1995 BMW 525i and the fuse for the AC keeps blowing after a few minutes. It's #9 in the fuse box. Before the fuse blows the AC works fine. I can't find any visible problems. Is there a common problem that I can check?

I can't say this will help for sure but, its a thought.. You'll have to check you're wiring, you may have an exposed wire that makes it short out, Ethier you're ground or power both could cause a short. Or just see if you can put a bigger fuse lol :P
