So I ordered a tensioner and belt. Today I finally got to it, and that's exactly what happened. One of the ball bearings got out and wedged itself on the pulley. The pulley had a melted segment of rubber on it.Probably the tensioner seized up. Fairly common issue, happened to my 03 too.
New GM Genuine replacement tensioner and Gates belt. AC is back to normal.
Thanks for your info.
