Quick Question, Are the ports on this manifold supposed to open and distribute the Vacuum? when the system is on, none of the ports draw vacuum pressure on my gauge. So I'm thinking that this thing is shot, but I want to be sure before I go to the junkyard and yank one of these or a few of them

An Update. I replaced the manifold (junk yard find) and I took off the ENTIRE vacuum system to pressure test the lines. I got new boots and elbows Y's T's etc and replaced the connections. so... now, I got control of the Defrost pod!

So, whats left?

I need to replace 2 footwell pods,

I need to figure out where a mysteryport goes

and I need to figure out why the Recirc system refuses to work.


Anyone know what this little port goes to and if it should hold vacuum? (see arrow point)

Please close this thread.....

Another Question. The system is Flushed out, but is there any Pressure switches or anything I should probably replace other then the Filter/dryer that would require draining the system out again? i'm looking to completely overhaul the system so when it gets turned on it will work, In theory when the button is pushed

I have a bit of a conundrum. my Switching Valve ( See post number 46) For the life of me I cant remember what goes where. Can anyone Give me a list 1-7 of where the vac lines go? I got the Recirc pods right, but the rest is a mystery right now

Conclusion, Everything is hooked up and working... Thanks for your help with this project
