How was it determined that you lost a cylinder? (I am assuming you mean in the engine).
Let's say through magic, you are only running on 5 out of 6. Missing a cylinder, is not going to affect your center vent in any way.
Not sure what kind of shape your 300E is in, but if you want, you can jury rig the flap open. To stop airflow, you can use the dial.

Thanks Larry..that is exactly my thinking was, as to how losing a 4th cylinder in the engine caused the center vent to stop working, I had taken it to the shop today and the mechanic told me that he tested the 4th cylinder by taking out the spark plug..his rational was that the the cylinder of the engine supposedly creates the vaccum and according to him when he checked the vaccum reading was between 5-10 instead of being about 25..so if there is not enough vaccum being created how do we know if the diaphrams are torn or bad or if it is the climate control. so we need to fix the 4th cylinder first to determine anything further.....by the way according to the thread on this forum..when the vaccum valve goes bad..there is a default where u get air from the two side vents and most of the air is coming from the defrost..and that is exactly my symptom was..I did rig the center vent and I am getting some air there but I still want to get it fixed...my 300e is in very good shape..I have always kept it in very good condition. pl tell me if I am going crazy/nuts
if now I am doubting my mechanic..this is the first time I have brought my car to him and supposedly only works on Mercedes...
