HH56's description of the heater arrangement is correct; also, he provides good trouble shooting suggestions.

If I recall correctly on my '47 Custom Sedan, the underseat unit is controlled by the "Heater" switch and the heater-defroster unit on the firewall is controlled by the "Defroster" switch. Your Packard may be different. I have found that is easy enough to remove the front seat cushion to check the top of the underseat unit.
