Start by finding the wiring cable to the fan and disconnect it. Jumper 12 volts directly to the fan end of the wiring cable connector. If the fan spins then it is good, if not you need a new fan. Find your fuse panels, usually one under the hood and one under the dash. Legend for the panels is usually on the inside of the cover and in the owners manual. Find the fan relay and replace it, they are cheap. If that does not fix it, you have a temp sensor screwed into the head somewhere which trips the relay when it gets warm. Go to autozone or advance and buy a replacement, find the one on your head which looks just like it and replace it with the new one. Bear in mind there may be more than one sensor, replace the right one! If all of those steps are done and it still does not work, take it to a dealer.
The most common reason for this is the cooling fan sensors, or also called coolant temp sensor and fan switch, there are two and both should be replaced, they are located at the housings where the hoses connect to engine, follow the top and bottom hoses to the engine and you will see the sensorsone is located at the front and one at the rear good day.
