Heater knob normally worked a switch and kind depended on what was installed. If it was the typical postwar install with 2 separate units -defroster and underseat or what Packard called the dualstream heater with one wire to the motors, both heater and defroster switches usually were identical --2 terminals and had off and 3 speeds. If the single combination dash heater/defroster with reversible motor was installed, that switch has 4 terminals and 5 positions. Off and 2 speeds for motor rotating one direction for air to defroster outlets and 2 speeds for opposite rotation direction with air out the doors.
If the car was optioned to the hilt and switch area was full then some switches had to go under the dash like prewar conventional body installs or doubled up. Heaters and fog lights were good candidates for being relocated.
The defroster came in two types. You have what Packard referred to as the footwarmer version. It was a (mostly) defroster but the little knob operates a tiny door opening so some of the defrost air is deflected down to the floor.
The fresh air option was a long tube which spanned the distance between the grill area and a hole in the firewall opening into the heater. At the firewall end was a flapper door operated by a cable which would allow fresh air to enter directly behind the heater. If the dash end looks like this factory piece then they might have used one of those cable setups to operate the water valve.
