My software doesnt have the wiring diagram for the cooling fan, Mercedes is stingy like that.Does you Benz have a manual fan as well as the a/c fan? If it does look to seee if the fan clutch is leaking in the front, sounds like it isnt pulling enough air at low speeds and may need to be replaced

easiest way is to use a mirror and look at the front (side facing radiator) of the fan clutch. If there is fluid coming from the center of it, you need to replace it.
