Both fans should have the same connector. Turn on the a/c and test both fans by swapping the connectors. This forces both to run and will tell what is working. Sometimes the radiator fan is not needed
unless in a heated area like the desert or extreme south.

In general, vehicles with electric radiator fans use an electronic temperature control so the fans only run as fast as needed. The energy to drive the fans come from the fuel you burn, so this is supposed to improve fuel economy. The air conditioner load makes the engine run hotter, so the fans should come on then.

Now, here is the real question: is the engine overheating at traffic light stops? Do you see an abnormal temperature rise on the dashboard gauge (assuming you have one)? If so, you may have a problem with the fan motor bearing, check for smooth and easy rotation of the fan when the engine is cold (it's dangerous to do so when the engine hot; the fan may come on even with the engine turned off). On the other hand, if the temperature indication is generally lower than it used to be, the temperature sensor may be going bad and is not calling for the fan to be on when it should be.

My santa fe has a cooling fan that wont stop runningstays hot but dont over heat


Sounds like a defective coolant temperature sensor. You didn't tell us which engine is in your Santa Fe. 2.4 4cylinder, 2.7 V6? or the 3.5 V6?
Without diagnosing this problem myslef, there are several probable causes (first, coolant temp sensor), next could be wiring, ECM, welded contacts in cooling fan relay, short in relay circuit, etc.

Heater problem


is your heater set on defrost this will cause your engine fan to run because it turns on the compressor for air conditioner this helps to extract moisture from your warm air defrost  and the fan in the engine compartment helps keep it the engine cool from the extra load on the engine this is normal
