I have a Model 65 heater which I intend to install in my 51 B3B. I'm trying to figure out how the simple-looking defroster valve works. It seems to me the valve should open up when the defroster cable is pulled out and it should close when the cable is pushed in. From my perspective it looks like it would work opposite to that. Should the cable be threaded into the top of the hole in photo 2 or come up through the bottom? Should there be a spring somewhere to help close the valve or does the cable alone open and close it? I'm scratching my head on this one.

The layout of the heater/defroster and vents of my recently acquired 1947 Chrysler New Yorker Sedan appears to be so basic that I am beginning to doubt whether this really is a New Yorker at all and it may be a re-badged long wheel base Windsor or some other model. I guess that I can check the serial number against some online references that I have browsed and I shall do so - but here are the things that I have noticed and maybe someone can tell me - New Yorker-or - not a New Yorker: A. I have the parts catalog and I have looked at the exploded view of the windshield defroster vents for a '47 New Yorker and I see that there is an uptake under the dash on both the left and right sides of the windshield. In my car there is only an uptake on the right side under the dash and by the time the air from the heater gets to the left side of the windshield - where you need it most- it is cool and blowing very weakly. From my inspection it looks like that is the way the car was built - it never had an uptake for the windshield defroster on the left side. New Yorker? or Not a New Yorker? B. My car only has one heater motor - the internal MOPAR heater on the passenger side under the dash and the defroster function is operated by a cable -pull choke-like switch attached to the heater and the heater function is achieved by opening up a small "door" on the heater. It is a very basic heater-defroster set up that one would find on a Plymouth (I used to have a '49 Plymouth). I have also noticed from pictures and diagrams that New Yorkers seem have an elaborate heater system with big vertical vents on the driver and passenger kick panels. It doesn't look like my car ever had them - or if it did they were removed and replaced expertly with period appropriate materials. Further, the "heat", "defrost" etc labeled knobs on the elaborate New Yorker dash are all fused and fixed in place and not connected to anything - I would have expected that these knobs would have been left out altogether if a 1947 New Yorker was offered new with such a basic heater/defroster set up as I have described above. New Yorker? - or-Not a New Yorker? Not trying to be overly fussy about this - I am very pleased with this car-if possible I was thinking of trying to restore the heater/defroster set up to conform with what options were originally available but I don't want to proceed upon the false premise that this really is a New Yorker if that is not the case or, in the alternative, if this basic heater/defroster set up is correct for a New Yorker then I will be happy to leave it as it is. If anybody has any information that can set me straight about this I would really appreciate it.
