68-70 B-body factory a/c vacuum line routing

[Richard Cranium]

Has anyone got a diagram of what hoses go to what diaphragms?

 

[mopar 3 B]

Not without knowing what system and veichal.
Have got 68 Chrysler-Plymouth.

 

[Richard Cranium]

Factory Chrysler system. 68 Charger, which I assume would be the same for other B-bodies of that ear.

If no one beats me to it will post tonight.

 

[mopar 3 B]

if this doesn't do it will try to get some pictures of the RT this week sometime

Well that did not work. Wil try again.

 

[Richard Cranium]

This is actually clearer than what my 1968 manual shows. Thanks!

 

[mopar 3 B]

Great.
Was prepared to take some pictures this weekend if needed.

Last question;

Is this the correct orientation as viewed on the drawing with #1 being the bottom left on the row of three & #7 being on the top left?

Look at fig. 46 in post 6. Top right of page.

No, you have it upside down. The bottom row has 4 holes and the top row only has 3 in Figure 1.

Got it!

 

[Richard Cranium]

Numbers on each end of the vacuum lines solved that issue.

Last question; where does this tee into?

 

[mopar 3 B]

I will check when I get home

 

[mopar 3 B]

Found it

 

[Richard Cranium]

All the vacuum lines are hooked up properly and things seem to be working with the exception of the floor heat function; it still blows out the vents. Any thoughts "Oh Wise One"?

 

[mopar 3 B]

Give this a try.

 

[Richard Cranium]

The main door in the front center of the box will close only when in the defrost position.

Floor heat is controlled by two small doors on the bottom of the unit that are manually opened and closed. Small wheels stamped floor heat.
My manual does not show them. They are just above the front of the console.
From what I have found they will not heat the passenger compartment on their own.
