Left Half of Center Vent Not As Cold As Right

Car is '97 W210. I get lots of cold AC out of right half of center vent but the temperature of the air coming out of the left half is much warmer. I've run the flap tests referenced here and the symptom holds. Turning down the left side thermostat helps but not much. Are the actuators for the flaps vacuum operated? Can they be gotten to without removal of the dashboard? What could be the possible causes?
