The first thing I would check is the Tensioner pulley and the Idler Pulley. Turning on the A/C will put a little extra pressure on the belt.
To check the pullies 1st with engine off spray the center bolt on ONE of the pullies with WD40 or similar, then start vehicle. If squeal goes away replace pulley, if squeal still there repeat proceedure with other pulley.
