    Cooling fans

    Not sure if I've got a problem with the cooling fans on my 3.2 but the smaller of the 2 never seems to work.
    I can hear the larger one come onto high speed when the aircon is on and also onto low speed when the engine needs cooling, but even if I leave the car ticking over, I've never seen or heard the small fan work.
    I have the car in at the dealers at the moment for some after purchase remedial work, but as they are a Mercedes dealer they don't know the correct operation of them.

    Any ideas?

    I had an LCR a few years ago that had the fans replaced, but that was because the slow speed had gone.
    Maybe it is working correctly, but I want to make sure while I have chance to get any problems sorted!

    There's a bit of info in my Air Con FAQs thread. Basically the car uses 1 for air con and both for engine cooling. VCDS is the way forward here.

    For advice on Air Con problems please read my FAQs.
    To find ASN members with VCDS check out the MAP.
