Anyone replace the ac condenser.
You might be confused, and are calling the AC compressor a condenser. If so, the squealing noise is likely coming from the AC compressor drive belt or tensioner.
Replacing the compressor is actually pretty easy. You'll need to take the car to a shop to have the AC system completely evacuated. Then remove the drive belt. Remove the bolts that hold the compressor to the block, and then the AC lines from the compressor. Disconnect the clutch coil connector and replace the compressor. Add oil if necessary to the new compressor, and reinstall. Take the car back to the shop to have it vacuumed and charged.
I noticed you stated that the noise is still there even with the AC off. That means the noise is NOT coming from the compressor itself. It is most likely the drive belt, the tensioner or idler pulley, or the compressor pulley and clutch - in that order.
