Some of the fresh air heaters in the AD trucks had a cable that activated the flapper inside, to turn the defroster on and off. Where did the knob end of this cable mount on the dash? I can't seem to find that detail in any of the books. It seems strange that none of the parts dealers mention this cable, at least not that I can find.
