    Dodgy fan switch? Only one speed.Now Zero speeds!!

    Well...I was going over some really bumpy roads the other day and it seems after this that my fans started acting up and didnt cut on in traffic today. (could be coincidence though) Luckily I noticed when it was at 90 degrees + 2 notches where the fan should kick in...

    It didnt and the temp kept rising so I pulled over..opened the bonnet to have a look. Checked contacts..Nothing!
    Slammed the bonnet shut...fan kicks in!!! (dodgy contact>???)

    Same thing again. Got to lights..temp kept rising. opened bonnet...pushed connector to back of fan. Fan kicked in and stopped shortly after.
    This didnt work again so I just made sure to avoid traffic on the way home

    Ive changed the MFTS and the after run switch very recently so its not these....
    Im pretty sure it must be the radiator fan switch...anyone have a pn for this??


    Cheers

    Location of fan switch.

    The fan switch is located right at the bottom of the main rad on the same side as the fan. You cant miss it as its the only thing at the bottom of the rad with wires coming out of it. To change this you will need to drain the coolent unscrew it and replace it with a new one. Hope this helps.

          Gilders are my friends
          To be fair though the fan only had one speed since Ive owned the car (extremely fast!) so this part has been required for a while now.
