    When I take the switch off the ignition and remove the key, My radiator fan decides to switch on at full speed even when the engine is stone cold,
    I have changed the radiator fan control modual, which I finally found bolted to the front panel underneath the headlight in the front wheel arch housing.
    Would the temprature sensor in the block be at fault? Or what else could I be looking for at fault.
    Thankyou for any help given

    Do check for water or damp in the control box with the 2 lids, you may have to lift the SAM and look underneath. if any damp then get the 2 modified lids and seals

    Would that be on the left or right of the engine bay and where would I get these modified lids?
    Thanks again

    I can only give you the known faults that are in WIS, this was a very common problem a few years back and ha been quiet of late.

    That control box behind the bumper can fill with water, and that was the most common of all
