Welcome to the forum, if it's your radiator fan that doesn't work? Take the electrical connector loose, use jumper wires to battery B+ and ground, use inline fuse, see if the fan will run ok? If it does, then check the fan relay, underhood, passenger side firewall, the one to the right. If you can see the wiring colors, two red wires, dark green, light blue. The two red wires are hot all the time. The pcm gets info from the coolant temp sensor.
