I assume your talking about the engine fan, not the cabin fan. The engine fan is designed to come on only when the engine gets hot enough for it.

Why does your fan not kick on until you put your ac on?

AnswerThe fact that it comes on when the A/C is on indicates the fan motor is good. The fan will only come on when the temperature sensor indicates the engine needs additional cooling. While traveling down the road the fan will rarely come on. It will come on in stop & go traffic. If the engine is not overheating, then you have no problem.there is a fan behind the radiator that is temp controlled & a fan in front of the radiator that runs when the A/C is on.
