Could be the ECM is not getting the signal that the A/C is on, but it would have to data scanned to find that out. The ISC could be stuck so it can't idle up when a load is sensed by the ECM. Something you can do yourself if your careful is clean the throttle body and remove and clean the ISC unit then put it back on, and then fire it up and let the idle stabilize then try the A/C.
