My understanding is the vent controls are vacuum operated. I do not know exactly where it is, but there is a vacuum line that came loose on mine and only the outside dash vents for a/c worked. After 30 minutes of tracing vacuum lines, a mechanic friend found it.

This feature confuses a lot of new owners. Unlike a lot of other cars, MBs do not push much air through the center vents.

So you don't fall asleep while enjoying your ride through the park
Same as having to stop to change from Miles to kilometers whereas Toyota you push a button while on the fly.

As mentioned, there are vacuum operated flaps which divert the air flow depending upon CC settings. There is actually a WIS test procedure to follow for determining which flaps are not working based on a series of settings and observations. It's pretty detailed and long.
