Have posted this before, searched this site, and would like some assistance here...the car is the 1995 E320 Wagon, low miles, with auto climate control. It has the temp wheel, then the 5 or six pushbuttons for air distribution, including the EC (Economy) setting, and then the 3 fan speeds buttons. (Hi, Lo, Auto)

Problem is this. After having a dead battery (may be a total coincidence), the previously perfectly functioning climate control now only blows air from the defrost (windshield) vents and the 2 outer dash vents, like it is stuck in the defrost position. In addition, the recirculating / dust filter no longer functions. The switch lights up, but airflow doesn't change.

Regardless of what position the pushbuttons are in, airflow does not change.

Fan control still works fine, as does the temperature setting. The fan will automatically slow down when the temp is reached. Cannot tell if the a/c system is working because it is too cold here for that. It does click on under the hood, though.

I think the problem must be vacuum related, dealing with the air box control shutters, or something. I could really use some help here.

Thanks
