I will not contest your diagnosis. I will also advise AC clutch replacement is not a DIYer job due to special tool needs,but you can still try if you want.

How old is the serpentine belt (if it has one)? The serpentine belt on my 93 Caprice was nine years old when I got it. I thought the AC compressor was shot from all the noise that was coming from it. I replaced the belt and no more noise from the compressor. The belts are replaced on my vehicles every 3 or 4 years or 40k miles.
