Default Re: MD Ecoboost - cooling fan not turning off

Very interesting issue ,needs further electrical investigation to determine were/why the fan module is still receiving power after shutdown....what is your engine temp? will it do it even if the engine hasn't reached operating temp? Is the A/C on when it does it? Also rather than disconnecting battery an easier option is to pull the fan relay(also not a bad point to start your electrical checking)
