Check your engine cooling fan, with a/c on it should run all the time and as the coolant temp rises, it should run even faster. Check the fan relays in the power distribution center near the battery. And the cooling fan motor. Run a fused protected wire from the pos battery post to the fan motor, and one from the neg, see if it runs, if it does the relay or engine coolant temp sensor is bad, if it doesnt run, replace the fan.
