W220 S-Class Problem with the Heat coming out of the middle vent
I just got my car back today, hood and bumper was repainted cuz of all the chips, the thing was all buffed out and whatnot... I noticed that the heat does not come out of the center heat vent. It comes out of all the other vents on the side and back. The only thing that comes out is cold in the center vent. I turned it all the way up to HI temp with MAX fan speed, nothing came out, when it was like say 75 degrees, cold air blew out of the center, I think the cold air works in the center vent but the hot doesn't! Any ideas???

If you turn the wheel slightly just until it is not at "auto" anymore it will work fine. Just try it.
This middle vent has an own electronic unit that sometimes gives wrong information to the A/C control unit. If you want this to be solved you should replace it.
