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?
