Loud squealing when I shut off the A/C

Hey guys I just picked up a 94 YJ and love it. My only issue is I turned the A/C on today for the first time and now there's a very annoying squeal when I turn it off and the occasional LOUD squeal for about half a second. It wasn't making any noise prior to turning the a/c on today and the P.O. thought it was broken could this be from lack of use? Thanks

The belt is squeeling, the compressor clutch is squeeling or the idler pulley is squeeling. Drop the belt aand see if all the pulleys are good looking for any rust foreign debris or oil. Then check the belt. It hasn't been used in awhile and when you used it it engaged the compressor vis the a/c compressor clutch.
