If you are moving down the road , car should not overheat. The fans only come on to provide air flow when not moving and engine hits a certain temp. If your vehicle overheats while driving , it could be a stuck thermostat or your radiator is pluged up. Water pump could be the issue too , but usually if they fail there would be a coolant leak clearly visible.

Most systems work pretty much the same. First check the fans themselves by hot wiring them to the battery. If they work, you need to check the engine temp sensor (some vehicles use one for gauge and fans, others use a separate one for fans) relay, and of course any fuses.
You will help yourself a lot by getting either a chilton or haynes manual to show you how to do testing.
