    If you check the fan by taking power direct from the battery and just make sure it is not seized. If that works, look at the fan switch in the cooling system, they often fail and are cheap to replace.

    Cheers.
    A quick shifty in google makes the Final Stage Resistor (hedgehog) favourite.
    But I'll take your advise first before splashing out.

    yes test the fan on the battery, if that works then start testing the circuits it connects too

    My money is on your ignition

    Presuming the fan is electric and not viscous, it could be the temperature switch. You can short this out by running a wire between the contacts.

    Which fan? cooling or a/c?
    As the ac ones were prone to seizing up, because the wax used to dry out inside.

    I always thought that engine had a viscous fan which turns all the time and speeds up depedning on temperature.
