My cooling fan does not seem to run. The car is running and at temp but the fan is not running. How can I tell if it is the fan or a fuss? How can I test the fan?
Is this a good question?

Rick, you usually check the radiator fan by disconnecting the coolant temp sensor and see if cooling fans come on. Your Kia's engine will have to be running , the sensors are usually connected to the thermostat housing. Check fuse #4 in the engine compartment fuse box, that is the one for your cooling fan. You also want to check the fan relay. the fan relay is in position #37 in your fuse panel
Here is the wiring diagram for the cooling fan circuit.
Use a paper clip to jump from the #30 to the #87 socket of the relay then turn the key and the AC on. If the fan comes on you know it is good, but if it does not, use a testlight at the fan connector and see if you have power. If you do, then you know your fan is bad.
