first unplug the cooling fan at its plug and supply 12v to the fan if it doesnt run then replace if it does run follow the power wire to the thermal water switch usualy located at the bottom of the radiator.Use test light/probe to check that you have power into the switch and when engine is hot you should have power both in and out of the switch.if not replace thermal water switch.If that is working you will need to find out why you have no power to the switch.Check that your fuse and relay is working correctly.Sometimes just pulling out the relay and putting back in will make it work due to poor contact.Also try swapping relays with others in the same box near battery to identify if relay is faulty

Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!

On top of the headlight housing are two large knurled black plastic knobs.Unscrew them counter-clockwise.Now the whole headlight housing may be removed. Set it on the bumper and you'll have easy access to the marker light.

SOURCE: Cooling fan not activating
On most vehicles, there is a thermostatic switch located on the bottom tank of the radiator that controls the electric fan.
When AC is turned on, this switch is bypassed so its failure is 'cured.'
These switches aren't terribly expensive nor difficult to replace but ensure you don't lose coolant on the ground while replacing the switch since the stuff is tasty and toxic to animals.
If you like to be able to research and or repair minor problems like this, you might consider buying the Haynes manual for your car. This will also let you approximately access what a repair might cost for labor if you can see the degree of difficulty yourself.

These are available at auto parts stores often cheaper than the online price. We have on for (and IN) each vehicle we own since they can be lifesavers now and then.
