Installed the exhaust hot air heater duct in the 39 Lincoln Zephyr today, the 6 volt blower motor works fine. Removed the old asbestos connection on the duct work that goes into car and replaced with 2 1/2" flex exhaust pipe. Next I decided that I did not want to disturb two head bolts to fasten the blower motor in factory position for one winter Christmas parade this coming weekend. I mounted the blower motor on the inside fender well and used 2 1/4" flex exhaust pipe. Started 12 volt car and then ran blower motor with 6 volt battery charger. It is good heat and very strong air blowing in car. I can see a problem if you had a engine that smoked, anti-freeze leak smell and it would suck in engine air, need an outside air source. I am sure this is how heater air source evolved. Also tested the head lights with new 12 volt head lamps, looks nice.
