Radiator Cooling fan always on til dead battery

Recommended Posts

Hi All,

My Fiesta 1.6 TDci 2010 cooling fan has decided to run continuously and thus flattens the battery. From my fusebox it says that the R7, a grey multi-reley  marked  8V5T-14B192-AA, 12v 30A.

Unplugged it, no difference. Mailed my local (retarded) Ford center who said it needed re-wiring etc. I then saw a post from Ford UK saying that the relay R7 is being replaced by a bigger relay named  F8OB14B1922AA that is a 12V, 40A instead of the 30A.


Does anyone have a tip? Oil level good, water is OK. Temprature sensor? Is R7 the only relay to the fan as I know?
