Fan,,,does it work.  Find the wires from the fan, and they should go to a temp switch located on some part of the cooling system.  Hose connection, block, radiator, etc.  Straight wire the fan to the battery, if it comes on,,,fan is good,,,,

If fan is good, check the fuses.  If fuse is good,,,,,

Replace the switch that the fan plugs into.
