Thanks for the input PHAT. When you turn on the A/C (pressing the button that is) do you hear the compressor engage? It's very noticeable at idle as a click/thunk, which is the compressor clutch engaging. On my vehicle that only occurs when the fan is turned on or off.
If you know which pulley to look at you can also check if the compressor is running visually. That stopped the dealer really quick from telling me that click noise was just the fan turning on.

OK, I toggled the switch again and I seemed to notice a slight drop in the RPM's when the A/C switch is turned on. Also, I hear a slight noise when I turn the switch on - the noise isn't very loud, as in, if you weren't listening for it, you'd probably not hear it. I'm not exaclty sure which pully it is, but if you can describe it, I'll check it out.
