AC/HEATER Control Block

[dburkett8]

Help!

Does anyone know where i can get the AC/ Heater pneumatic control block for a 71 charger (i think its the same for all 71-74 b bodies). Pictures are below. I searched online but all i keep pulling up is the model for 67-69. My old one has 2 pneumatic ports that broke off.
If any one has one for sale or one info on where to purchase one please let me know.!!

I pulled it apart just to see what was inside and seems forced air moves a block distributor along a guide.

3431572 or 3431127 depending on late or early production.
See http://www.dodgecharger.com/forum/index.php?topic=76665.0
there is a 3431571 on EBay but I have no idea what the hell that is in the picture.

Having said that it is a reasonable price as opposed to http://www.ebay.com/itm/NOS-MOPAR-1...m35fd22783a:m:mqtE1GjRmVWDhmg1aUJM-vw&vxp=mtr
This thing has superseded so many times it is hard to find the correct one.
Someone also said on one of the forums that Advance or Auto Zone had one that worked, but I can not confirm.

That part is not cheap. This is where I got mine

I probably have a few whole assemblies if interested. May take a few days to find them loose as the ones I have that I can find quickly are on complete dash assemblies that I don't want to part out....

Just so you know 71-2 is different than 73-4.

What is different between the two, are they interchangeable though?

They rebuild them, so where can I get parts and rebuild my own?

Never seen nor heard of them being rebuild-able

Switch physically looks the same, but the off position changes ( allong with the rest of functions

Note the 73/74 control setup

Somebody at DC.com rebuild the ram hood switch vacuum ports with a tube similar to the lollypop stick ( you know? Those with the center hole ). Just drilled a bit the housing ( not too far, just enough to keep and glue ) and inserted the piece.


It can't go to the end to keep the smooth surface inside to the rubber pad

Thanks everyone. I found someone who was selling one and I purchased it.
