The heat output on my 300D after about an hour running changes from the drivers and the passengers sides. While the passenger sides' temp stays the same, the drives side output gets colder. So increasing the temp selection really cooks the passenger while the drives gets a little warmer. Any ideas?
Also have notice lately a slight smell of anti-freeze inside the car. How difficult to repair?

A great guy passed away on monday 4/9/01. His name was Frank Clancy and he worked at a Mercedes dealership here in Exeter,nh. Had a heart attack on the way to work. He was 65 yrs young.Always had a smile and glad to see you...not for sales but a genuine guy. He will be missed greatly because he was from the old school and really knew the older models. No disrespect but the knowledge of the older cars is slipping away. So heres to Frank.. God rest You were the best!!
