2002 Trailblazer, air condition runs great, but car dies with it on if I stop!!

The problem might be with the Idle Air Control valve.

This is what controls the engine idle speed when different loads are impossed on the engine when stopped and idling. So if the IAC valve fails to go to the proper position when the AC is on, the engine will stall when stopped and idling.
