Cooling fan

Could be a few different things causing it not to come on start off with easy stuff first. Under hood fuse block has cool fan 1 and cool fan 2 fuses check them first. If they are good unplug fans make you a couple jumper wires ground black wire and one if the others (either one of the 2 that are not the ground) hook up directly to 12v lug that sticks out of the under hood fuse block. If they run then possible ecm not telling them to come on. Then you can either have ecu programmed or just run them to a switch or aftermarket thermostat you can pick up at about any parts house
