Heater / defroster paper air duct

[pflaming]

To remove the wiper motor and arms, I had to remove the dash. Once removed, I noted the 'paper' defroster air duct. I carefully removed it so I now have what I need to make a new one. Are replacements available, or has anyone improvised a new design. 

[Dodgeb4ya]

Dash doesn't need to be removed to pull the wiper motor or arms.

What dia is it? Replaced my car defroster hose, it's 2 1/2", vinyl w/wire, and have the extra.

as always e-bay is your friend...this is just a general listing using the words defrost duct....you will see in just a few seconds the various sizes available...you do not have to buy from here but it can quickly tell you what is available and often the part number.... then go to your parts store, get out the four season parts book from under the counter, often you have to tell them they have one, and get what you need through your local friendly...

You talking about the large cardboard piece that goes side to side against the firewall? I would clean and reuse it unless its damaged. I doubt you'll find a replacement anywhere. 

[Plymouthy Adams]

I could be out on a limb..usually the upper hoses as found in and near the wiper motor are the interconnecting  round hoses to the metal outlets covered by the window garnish..

That paper duct distributes heat across the front of he cabin, out of it is one 2 1/2"  hose to the defroster 'tube" which is a part of the frame. So then some creative duct can carry  the heat across the front, if that is one's preference. 

Yes, the wiper motor et al can be removed without removing the dash. Either way, the nuts are square and require a 5/8 " wrench. Is this motor common to all Mopar  vehicles of the time?

I'll put my 2 1/2" black vinyl defroster duct in classifieds. Doubt the motor is common, they changed a lot. Vacuum or electric? It should have a name & number on it.

[pflaming]

Wiper motor number is Auto-Lite EMG 410 2B, 6 volt, three wires. I have two but need to determine if they work so not in classifieds as yet.

Here is what I used for under dash air ducting in my '37 Plymouth:

Air ducting

This material is corrugated aluminum reinforced with spiral wire and sheathed in plastic. 30 mm diameter fitted the outlets of my air blower, but other diameters are also available.

Pflaming,

 

   Would the wiper motor work in a 1946 Plymouth? It’s a 6v neg ground, but I don’t think the polarity is an issue. I’m a very old hot rodder, and very good at fabrication, should that be necessary. We’ve currently running a vacuum motor, but it doesn’t work all that well, and if the glass is dry, it’s too much resistance, and it won’t work at all. I’ve tho’t about sending it to Ficken Wiper, aka “The Wiper Man”. I’ve seen his work, and he does top notch work. But, if I can convert to electric for reasonable cost, it’d be a consideration. Thx.

I'm replacing both hoses on my 1948 Special Deluxe.  All original heat and duct hoses.   I'm pretty sure my hoses one long for drivers side defrost and one short for passenger side defrost . There 1 3/4 ID If I remember correctly .   You can get the hose in 6 ft lengths from your local Car Quest dealer or Orielys.     They may have to order it but usually have it within a day or 2.    Prices vary a bit approx $4 a foot.      Hope this helps

If you look back there is a post with a picture by me comparing a p15 vacuum wiper to the electric setup from a 46-48 Chrysler. I've been told it won't fit but it sure looks like it measures up the same to me. 

[pflaming]

I wonder if the motors are common, only the mounts differ, for electric applications. Just thinking out loud, I do not think my truck electric wiper is two speed. If it is a single speed, then I may try a swap.

 

[rb1949]

Got pix of your motors to compare mounting brackets?

Paul you have a picture of the paper heater distribution tube your talking about.

My 50 had a rather complex type of heat/defrost distribution that runs across the fire wall from the pass. side to driver side with some heat outlet in the lower middle area that was made of a paper? that crumbled if not handled gently which was only partially savable. I filled it with the aerosol type of canned foam and sanded the shapes to closely match what I believed to original shape. Made a copy with a steel sheet back and fiberglass front shapes. Came out fine  but was a lot of work and sanding.

Assume this on the Suburban and not the truck.

DJ, I could do as you have done, but I can restore the inlet end which has the defroster gate and then only a 5" coiled tube is required which I have. The remainder of the paper duct disperses air across the lower front, more a comfort issue than a heat. There are other ways to get heat across to the driver's side. 

So the key part is the gate end which I have.

 

[DJ194950]

well the 50 of mine is probably different from yours, just my attempt to keep as close to stock as possible and it works almost too good.

Figured a big Suburban can easily use as much heat distribution as a 4 door. It's not just for the driver!

 

[pflaming]

DJ,   possible requires MORE heat with the wagon cabin.  Nice work on that duct. My Dad's 46 chevrolet had the heater under the seat on the passenger's side. I wonder how many of those survived?

Very early heated seats??

DJ

[pflaming]

Very early heated seats??   Yes but they were called hot water bottles! 

[DJ194950]

Only time I remember of hot water bottles was when we were tent camping in the late 50's at about 5000 ft. elevation,mid summer, and a aunt of mine refused to go to bed without 3 of them and water still over the last of the fire for later!  Oh ya, she and her family only did that twice with our family! Twice to many!

DJ

[Don Coatney]

They called them hot water bottles and every bathroom had one in the 50's. But hot water was not there real function.

[Niel Hoback]

Man, how I hated that thing!  

[Dodgeb4ya]

This hot water bottle talk reminded me of a couple things  about the one we had as kids....

1)    I can still can remember how fast the plug screwed into the bottle with the course acme like threads.... I always liked screwing with stuff....probably one reason I ended up being        a mechanic

 2)    My brother and me had lots of hot water bottle fights.

 3)    The Strong man guys on the religious TV channels would try to pop them blowing them up like a balloon.

        I must say that red rubber was some tough stuff!

        Oh ... The memories...
