Suggest you order a new relay and replace the malfunctioning one.If has done it once it is likely to do it again.

The bear is 100% correct as to the confusion and how my TDCi works.

Thanks for the Manual number.Must be a recent publication as I.i am sure it was not available a couple of years back when we bought the Fusion.

 

Just n update on the situation.After removing the relay from the under bonnet relay box ,the fan stopped.Reinserting the relay the fan remained stationary.Car ran normally today.So I suspect this relay is intermittently remaining engaged when power is removed.Am going to try and find the part number and will order a replacement from ford.

Hence it probably being a faulty thermostat. Sometimes they just stick open with age and a slight raise in heat or it could even just have shorted.

 

Double check your fluids etc for a root cause, your fans obviously working but maybe your radiator could be obstructed. 

 

 

If you want to just isolate the fan, the plug will be along the front of the engine bay, the wires to it will extend rom the motor of the fan.

 

 

I have pulled the plug on the motor and the fan is now stationary.

battery on charge.Fluids are fine.

Not sure why you think the thermostat could be at fault.If stuck open the engine will not reach operating temperature and thsi will be reflected in a lower temp being indicated on the temp guage.If stuck closed/partially closed the temp will rise above normal levels and be indicated on the guage and this will cause the fans to come on.The guage reads normal but the fans stay after shutdown as if the engine was hot and keep running until the battery goes flat.I dont believe ECU will actually keep the fans  running until the battery does go flat.Will look more in depth tomorrow.

Good point ,however the engine was not overheating and the fan runs indefinetely after the engine is turned off,until in fact the battery is flat which takes quite a while.This evening the engine was cols and the fan slowly rotating with a flat battery.Put a jump pack across the battery and the fan speed right up again.

By the way do you have an manual for the Fusion.I cant seem to locate one other than fro the fiesta,which does seem to be a bit different
