Hello!
It is very common for the power steering pump on this model to break internally. What usually happens is that teh pump shaft snaps off behind teh seal area, leaving the pulley to spin freely without actually turning the pump.
Try removing teh belt, and see if you can pull the power steering pump pulley out of the pump with your bare hands.
Hope this is helpful; if so, please click my accept button! Thanks!
