1972 W107 heater blows hot air on my feet

Brand new to an old car, living in the heat of Georgia, and my feet are being cooked by the heat that will not shut off. The AC will blow out of the dash vents, but the vents in the footwell blow warm-to-hot air constantly.

Is it something as simple (and infuriatingly difficult to fix) as a stuck cable or stuck door, or is it some gyro/servo gizmo?

Pinch or block off the vacuum line to heater valve located on the firewall. This should at least turn off the heat.
