The vent control is not working. It is either electrical or vaccume. The controls are not effectiong the vents. They could also just be stuck. The vent controls are usually found under the dash. hope it helps. duboff

Sounds like the heater control valve. It could be the blend door actuator motor,which is located on top of the heater housing. this is what controls the fresh air flow through the heater.

Why Mercedes heater blowing hot?
I had a W126 Benz (1981 280SE) on which the heater would not turn off on one side of the car (it has separate heaters for each side). The problem turned out to be a broken solenoid valve in the heater water supply. The way the heater works is: With the ignition off the heater valve springs open. When the ignition is turned on the heater valve automatically closes. When you then turn on the heater controls the valve opens again. I think the idea is that the heater valve gets "cycled" every time the car is used so that it doesn't get sticky. The electric solenoid that does the closing is easy to find by following the water pipes and will probably be on the firewall somewhere. They are supposed to be a throwaway part but I got mine open and soldered up the broken wire and all was good.
