cooling fans stay on, engine could be overheating, faulty cooling fan relay or pcm could be faulty.best get vechicle code scan before spending too much money you need scan to see what engine coolant temperature is,scanner can tell you if engine getting too hot could have partially closed thermostat,clogged radiator cores clogged engine block coolant passages clogged also the heater core, if engine not overheating the code scanner will tell you if you have faulty cooling fans relay or pcm failure.
Buy a thermostat, a thermostat gasket, and some blue sealant (RTV) from any auto parts store. On the driver side of the engine, there is a radiator hose that connects to the engine just under the wires for the spark plugs. There are two bolts. Remove the bolts and pull off the hose. Some coolant will leak. Remove the old thermostat and gasket. Note how the thermostat is oriented so you can replace the same way. Put the gasket and thermostat back using some of the sealant and then re install the bolts.
Total cost is around 15-20 dollars. Feel good that you saved a few hundred bucks and only takes about 20-30 minutes.
