Radiator cooling fan

Where do I find the cooling fan relay and switch for it? Mine comes on late, and stays on a short time.
Over heating problem because of it.
Thanks

If the fan comes on late and only runs for a short time it sounds like just the high speed is working. Check to see if the fan runs when you switch the a/c on - it should do this at idle/rest. If not, it could be that the low speed winding has gone bad on the fan motor, your a/c pressure is low, the IRCM or even your coolant temperature sensor is bad. You can also check the low speed fan by pulling out the IRCM (in front of the air filter & behind the passenger headlight - remove your air filter/box to get some room then remove the screw/s from the IRCM frame, pull it out enough to identify the wires and corresponding numbers on the harness) and simply cut wire #14 - that should also cause the low speed to run (you can use spade connectors to re-connect it). If non of these tests work then it looks like you need a new fan motor. On final proof would be to disconnect the main fan harness and using some stout wire and a fuse in line (say 60amps), ground the black wire and try each of the fan power wires using the battery + terminal. Again if only one fan speed runs then you''ll need to replace the motor - about $100 at AutoZone.
