HELP: A/C and Heat
Need your help/input. My s55 blows heat, but not in the top center dash. All I'm getting is cold air.
I have watched YouTube videos and have read up here on MBworld, but must be doing something wrong still (sigh).
- What is the procedure to get the top center dash vents to mirror the main control by the stereo?
I do have heat in the floor and on the side vents at the same time, but not in the top center vents ) just getting outside air....and I have the top center control set to “auto”. I have also adjusted the top vents from small dots to large dots, but still get cold air and the A/C is not turned on (no red light).
I have never solved the problem; just kept tweaking to make it slightly less annoying.
