I did the air flap self-diagnostic test: 220695 c question mb w210 ac diagnostics flap test pdf free ebook download from mbworld.org
The whistling occurs with DTC 3. This points to the pod for "Left Blend Air Flap". Can someone tell me where this pod is? If it's on the driver's side as I suspect, then the dash may indeed need to come out.
Does someone have a diagram of all the pods and their locations? |
