Yes. Cadillac had a single knob which worked both inlets simultaneously but Packard had a separate knob for each side.
The mechanism the knob attaches to that moves the Bowden cable is very much like the windshield wiper motor actuator located inside the steering column. Difference is that Instead of a straight length of wire with a washer on the end that fits in the slider on the wiper motor, the mechanism for the vents have a loop on the end of the cables to work a smaller version of the flapper valve like the heater and air vents in front use. That flapper is located inside the metal adapter tube that is attached to the return plenums.

Are the knobs on the rear shelf the ones for opening the outside air inlets? Is it done through cables?
