AC blowing fuse

Got my truck from the paint shop a couple weeks back now when I turn on the ac it runs less than a minute and the fuse blows any ideas what the problem could be.

Bad ground or connection. Check the wiring to the A/C relay. The relay is located on the A/C box.

My 75 truck will blow on all speeds but high. I was hinted to that it may be the ac relay on the AC box. Anyone able to confirm that?
thanks

The sepped control on the dash is the most common culprit. Mine doesn't like working on speeds other than high, but that's ok. Hey, wait a sec. I've go the bezel off, may as well replace it!
