AC fuse keeps blowing. 91 fox 5.0

[shawn95]

About 2 weeks ago my ac stopped working. Found that there was a 20amp view under the dash that popped. Yesterday it popped again. I put a new fuse in it but now it pops as soon as I turn the ac on. Anyone experience the same thing? Don't really know the electrical side of this car. Thanks for any help

find the ac diagram on veryuseful.com and trace down the circuit looking for a short to ground is where I would start.
