On the drivers side air-vent, I can hear a strangle whistling noise from inside the duct. It is linked to the fan, but im unsure if perhaps its a leaf in there or if the bearing has gone in the fan? I hope if right in saying there is a fan in there somewhere to the right of the steering wheel, because that is where the noise is coming from. Sounds kinda similar to when a sleave bearing fan goes in a computer, but I would think mercedes would use a better quality Ball bearing?
