ac short

Hello all,
My ac is blowing the fuse wanna troubleshoot for the short circuit where do I start?

What year, what engine, and what fuse specifically would help a lot.

Its a 89 engine 2.0 and the fuse is 25

Try unplugging the compressore and see if the fuse blows. If it doesn't plug the compressor back in. If it blows the clutch/compressor is bad.
