There could be several reasons why the cooling fan/fans (depending on year model) will NOT turn on, however there is only two reasons why they WILL turn on, and that's because either the ECU has detected that the engine temp has risen to the point where the radiator needs additional assistance in cooling the water OR you have turned on the A/C.

Check your water level, and make sure it's not a dark dirty color. You may also want to have your system flushed/cleaned. Also depending on your mileage your thermostat may have gone bad and is not allowing enough water to flow through the engine. Lastly, but this is rarely the case, your CHT sensor may be going bad and it is telling the ECU that the engine is running hotter than it really is.
