    I have a 2003 volvo d12 engine and my fan stays on all the time. There is no power coming to fan clutch solenoid. I have replaced temperature sensor and AC high pressure switch and that didn't help, its on. Anyone knows why I am not getting power to that solenoid. Help is really appreciated. Thanks

    That is working properly, like I said power is not coming to that solenoid. I checked the wiring harness, looks ok. Not sure what tgis could be. I tried bringing power from the alternator to that solenoid and it works fine,. Prolem is just that power is not coming to solenoid and am not sure why

    trace the wires back from the solenoid if not just unplug the fan tie the plug up with a cabletie to it self done
    this means the fan will run all the time problem solved
    ''chances are when it spits the belt it will tear the wires off the fan anyway''
