Any GM mechanics Jimmy overheating problem

I just bought a 1996 S 15 Jimmy as is from a local dealer. Drove great on the test drive no issues what so ever. Next day my son was going to the local mall he said when he got there steam was coming out from under the hood. Opened the hood said water was coming from the overflow. Dealer towed the vehicle back to his lot had a radiator shop flush the system and replaced the thermostat and radiator cap.Seemed to work fine the next day ran a little hotter than I thought it should. Drove down past Selinsgrove using the ac car heated up. Turned heater on and opened the windows it cooled down according to the temp gauge. Drove home with ac off and no problems. Turn the ac on and it heats up . Any clues here guys ?

Too hot for splitting wood.

No water in the oil thought of that checked oil is good and clean. Has me baffled. Might be a trip back to the dealer. Both hoses feel ok not soft and from what I have read as long as both are hot then the pump is good.
