My 35 Dodge (from years ago) had small slots at the bottom of the windshield that were cut into the garnish moldings. Those slotted vents were supplied with fan forced warm air from a tube connected to the heat unit. I can tell you the warm air forced through those small slots cleared the windshield very quickly.
I suggest you use the area under the dash for heat/cool and windshield wipers, and run the electrical not needed in the dash, to under or behind the rear seat. The voltage in the wiring won't care how far it travels before it reaches its destination. Warm air from a heating unit can cool pretty quickly in a cold car, you want to keep those heat caring hoses as short as possible. Gene
Well now, there's some good info. Was that a stock type vent under the window? If so, then I should be able to find a pic somewhere. I was discussing that very thing with number two son, but he didn't think that you could get enough warm air through to help. I absolutely believe you when you say that would clear the windshield. There's no reason that it shouldn't.
Now that channel under the window on the '33 is a small box like section. I'm back at home now, about 500 kilometres away from the car, but I think that section is about an inch deep and maybe 3/4" wide. I could do a little sheet metal fabbing to run the warm air through and insulate that with stick-on duct insulation.
The wiper motor - single - is mounted overhead on this car. It sure could use a second, or even a third wiper with that low chopped window. I haven't measured the height of it yet, but the guys have very kindly given me info on their window heights.
Did the Dodge mount the wipers from below I take it?
I think in deference to the very kind original poster that I should be starting a thread on this car. There's a way to go yet and I'm quite positive there will be loads of questions still.
