It likely to be related to the AC drive belt. That would be the first thing to check. An old belt can produce a squealing noise.
Could be something as simple as the a/c belt out of adjustment. Worst case scenario probably would be the a/c compressor clutch or the compressor itself going bad, which is somewhat common on these.
