I might not have enough information but the squeal is most likely a worn bearing. Try to isolate it with a "mechanic's stethescope" to locate the source. A pin point shot of WD-40 at the whining bearing (NO NOT put it on good bearings should TEMPORARILY quiet it IF it is a bearing. DO NOT overspray, just at the center of the pulleys...the lubricant should get pulled into bearing to confirm that the pump (power steering would be my guess) needs replacing.

Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

first thing you need to do is get a new belt that belt dressing just destroyed that belt that stuff is no good then get a new belt tensioner clean all the pullys with some brake clean then install the belt tensioner and belt if its still sqealing there maybe a pully making the noise to check that when you have the belt off spin them by hand and listen to them and feel for any play in the bearings

Could it be the pulley on the AC that's squealing? Use a mechanic's stethoscope to locate the squeal. If it is the AC, you can get a belt that is shorter, and bypass the pump, since it doesn't work anyway. Try some belt dressing first. When the engine is running, just spray it on the inside of the belt.
