Before I moved to So Cal in April 56 I operated my '36 in Eastern Idaho, Wyoming and Utah, in temps in the low -30's. The '39 style heater did an excellent job in my car. The heater in my car has provisions for defroster ducts, there is a little knob on the upper left of the heater box that is pulled to divert air from the passenger area, they were never hooked up, no provisions in the dash, I have seen pictures of the defroster distribution ducts on the face of the '36 cars. The feature never appealed to me.
