The fan is operated by the Engine Control Module. it sends a signal to the fan hub to engage or disengage. If you fan is never coming on even when overheating then chances are the fan hub is shot. you can have the hub tested at the dealer with software to turn the fan on or off. that is the best way to make sure.

Real courage is found, not in the willingness to risk death, but in the willingness to stand, alone if necessary, against the ignorant and disapproving herd. — Jon Roland, 1976
