Whirring noise in engine
 

I have a small sorta high pitch whirring noise in my engine, not apparent at low RPMs or higher RPMS, just at about 1-2.5. Im gonna check my PS fluid at lunch. My AC doesnt work, could it possibly be the pulley?

Sounds like you need a new power steering pump...mine was doing the same thing on my 06 Monte, and I took it to the dealer, it was the power steering pump, they replaced it, and the noise is gone!
