This is a common question for new owners of Mercedes 190e. The center vents only blow outside air and conditioned air from your a/c. This is the design of the system. The reason Mercedes made it this way is to keep the driver alert and awake. You can adjust the flow of air from the center vents by moving the slider up or down, but the air will always be the ambient temperature from the outside or from your a/c when it is engaged.
You have not loosened the retaining bolts and nut so that the adjuster will move (more than likely).
Sounds like low coolant or air in the cooling system
