The high pitched whine sounds like something in the serpentine belt drive, which would directly affect your A/C compressor. I had an belt tensioner bearing go bad, and it made lots of noises. Easy to replace both the tensioner and the idler. Remove the belt to verify that is where the whine is coming from. Could be the A/C compressor, tensioner, or idler.
