Hey guys. I'm Steve, and my neighbor has a problem with the his AC blowing a fuse in his 95 GMC Sierra 5.8L. He says that it blows a 20amp in a couple seconds and I had him put a 30 in and it blew that in a couple seconds longer, so not a direct short. I'm going to check it out for him tomorrow, favor. Any suggestions were to start looking? I've never owned or worked on a GMC.

Any ideas or suggestions anyone?

check the clutch. It sounds like the activation coil is shorting out.
