Dave:
My heater has two fan motors. One with a fan blade to move air through the heater radiator and another in an attachment for the defroster on top of the heater shell. It has a small squirrel cage fan in that. The emblem on the heater says:
"Special GMC Heater".
It is not a fresh air heater.
Three rectangular outlet doors on front. Two knobs per door. Knobs are identical
to the knobs on the ashtray in my '51 Chev panel.
Thanks,
Jerry
