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

My name is Ron,Look on the firewall under the windshield ,behind motor,there should be a large cover .Remove this cover,and you will see a row of relays,the one that is warm or hot,is the one to remove(blower relay).When you remove the relay the blower will stop.this is the relay to replace. Hope I was some firstname.lastname@example.org
