    You may just need to top off your coolant level. Check that first. Make sure the coolant reservoir is up to the line with coolant. If it is not that, have a mechanic check the A/C system. You may just need a new engine coolant sensor or the auxilliary fan may not be engaging because of a bad relay or switch.

    It's possible that your cooling fan is NOT activating when the AC is turned on---there are instances where it should activate---see below for details:



    Vehicles Equipped with AC: In addition to using coolant temperature and battery temperature sensor to control cooling fan operation, the cooling fan will also be engaged when the ,air conditioning system is activated. The relay is also energized when air conditioning is selected and coolant temperature is above 95°C (203°F) , or, air conditioning is selected and battery temperature sensor is above 41°C (106°F) . It will then de-energize when air conditioning is selected and coolant temperature is below 92°C (198°F) , or air conditioning is selected and battery temperature is below 38°C (100°F).
