So are you saying if you press the demist button when the engine is cold the fan does not run - it only comes on immediately before it starts to overheat?

If so it sounds like you have the classic signs of the cooling fan silver resistor failure.

Dead easy fix - just swap it out with an upgraded gold one

Have you lost any coolant? - Remember to check the level ONLY when the engine is cold!

If the fan is running when demist is active on the ATC and the engine is cold then this is mormal fan behaviour; as others have already said, I would check the thermostat - even if there is no leakage they are known to cause problems!
