Have you replaced the thermostat? If not do so-and check the radiator if its clogged-up and also if the water pump is functioning -if both okay get it block and pressure tested.

Could be a fuse, fan relay, coolant temperature sending unit or the engine coolant temperature sensor

What fan motor are you talking about -is it the electric fan motor for the radiator or the blower motor for AC/heater? If its the radiator fan motor you best check what I've gave you. There's no fan controller.

If one of the items is defective the radiator fan will never come on. Good Luck

I had the same thing happen to me, I replace the fan motor and still did not come on, you have a fuse that is no good under the hood, replace the blowen fuse and your fan will come on.

Well bro I was just telling what it did when I have that happen to my car. I got a new fan motor and put it on, and still did not work. So I looked under the hood and I had a fuse that was bad or the name is relay fuse. So I replaced that and my fan worked fine. There is not switch so dont look for one you will be mad tring to look for it. Just fine the fuse under your hood in the black fuse box, replace the bad one bro.
