Sounds like the temp sensor has failed, and the ecu can see this so is flashing the light and running the fan, i don't know ford but seems like how that system might work.

I presume you have checked your coolant level & checked for leaks... you will need to see the temp in for being went to the ECU & confirm the thermostat is opening properly. Bring it to a mechanic before fitting any other parts.

Thermostat solved the problem, all coolant levels were fine, temp was reading OK on live data. Thermostat was jammed solid.
