Hi mike osborn,
Try swapping the relay, it could be faulty and sticking. The fan would come on for a short while after engine is turned off if the temp is high at the upper hose outlet.
If swapping does not help and the temp is not high with sufficient coolant in radiator, the thermoswitch at upper hose joint on head needs to be replaced.
