I started to get this whining under the hood. At first I thought it was the power steering. I heard several other Trailblazer making the same sounds, so I thought that it might be normal. It started getting really load, and embarrassing. I found out that it is the alternator. A new one cost $200. I have nothing but problems developing with my rig, and with less than 60k miles, I am an extremely disappointing customer. It is getting really hard for me to continue to buy American vehicles, when I have to spend my salary to keep them on the road.
Update from Oct 10, 2010: This turned out to be the idler pulley. The tension pulley is now going out.
