Are the cooling fans coming on ?


there must be 2 fans on the vehicle check if they come on, one for temp and other one is for the air-con, do agree with @firebird, check the fans first

the radiator fan is working good and the AC fan works when AC is powered on.


I would recommend cleaning out the radiator and condenser coil fins maybe partially clogged with dirt and bugs restricting air flow across the fins.
