    radiator fan runs at full blast all of a sudden 2013 335is

    Noticed a wierd sound today, to find my main radiator fan is running full tilt boogie all the time. First time this has happened.

    AC and defrost are off, interior heat/AC is off. all I can hear now is that fan.

    No codes or little triangles with "!" inside, but the fan now runs full blast while the car is running.

    It shuts off a second or two after I shut the car off.

    I read somewhere about people having a similar issue, and was wondering if there's a thread or someone can link me to something about this.

    Going to my shop tomorrow to address this but thought I'd ask here since I can't do anything til tomorrow.

    Any help would be appreciated.

    Mike

    That happened to a friends's 535i (e60) when his electric water pump was failing. It stopped as soon as we replaced it. We guessed that the car knew the pumpo wasn't working properly, so it was doing what it could to cool things down. That or a bad switch/relay, would be my guess.
