    Replace the sensor for your coolant, which is mounted in radiator. You can pick one up at Auto Zone and they can print off where the location is for you. messing with vehicles 49 yrs

    Turn on the air conditioner and see if they run. There are relays and a fuse in the big fuse box under the hood that can go bad.

    The fans aren't suppose to be on unless the engine is too hot or the A/C is on.
