The operation of the cooling fans may be interrupted by the ac. Check the ac fan relay and fuse. operating the ac puts a bigger draw on the engine and therefore more heat, some systems use a separate cooling fan cycling sequence when it is engaged. Does the fan run when the ac is off and temp is at operating range? Does it run when the ac is on? It should cycle much more frequently with the ac clutch engaged. First though be sure your thermostat is working, you have plenty of coolant, and a good rad cap.
