Your best bet is to get a mechanic's stethoscope like this and carefully (as in avoiding belts fans and other rotating items) listen to each idler pully while the car is running.

You could also remove each pully and listen for roughness and grinding when you turn them by hand - but my way avoids disassembling and reassembling the car with a bad pully while you wait for the part to arrive if it's not immediately available.

I haven't used that particular one, but the one I have used out of my dad's garage worked very well!
