Hi there, that sounds like the belt broke. I advise to stop driving ASAP. The engine can overheat then you would have bigger issues.
Expert:  Gm Tech (Cam) replied 2 years ago.
The belt drives the AC, Power steering pump, Water pump and charging system. So the combination of events you describe sound like the belt broke.
Customer: replied 2 years ago.
do you think anything else could be damaged? she turned it off not to kill the battery
Expert:  Gm Tech (Cam) replied 2 years ago.
Its possible there is a idler or tensioner pulley damaged, but that may have caused the issue in the first place, or possibly the alternator, AC compressor or water pump failed, what you do is check the alignment of all these, turn them by hand and see how they feel. All should turn very smoothly. IF any are out of alignment, stiff or seized, replace that with the belt.
