Im not near my diagrams for your car, but most of these systems are controlled by the PCM. It takes inputs from the engine coolant temperature sensor and the air conditioning system and decides when the fan is needed.
Most systems will run the fan, or one of two fans when you select the airconditioning on. The other relies on that temp sensor. I would probably replace the sensor. Find out from your parts store if they list more than one coolant temp sensor. Some cars do one for the indication inside and one for the PCM. Make sure you replace the correct one.
