It is the A/c clutch pulley, You can't buy just the pulley . A/c isdiffrent from ones in the past. Dealer wants $800 for new compressor. Found GMparts direct.com $406 gmpartsdirect.com: Alternate GM Catalog this place $365. I ordered it should be here next week. Problem solved.

I have an '03 TB LT with about 70k on it and I notice a high pitched whine too, but I only hear it when I'm accelerating (for the most part). It sounds like it's coming from the passenger side. I'm pretty sure its not the power steering and I hear it when the A/C is off, so is the idler pulley most likely the culprit? On another forum I saw the tranny pump mentioned... would that make a similar noise?
