vacume line help ... got info from another thread need more

[trickedastro99]

ok so i was doing some work under the hood this week ... flushed my radiatior and cleaned my overflow bottle and windshield washer bottle ... well i noticed some plugs not pluged up but cant seem to find where they go but another member tells me they are for my rear AC so im not too worried about those so i put everything back and now my AC wasnt blowing out the front vents only the defrost vents and i know this is due to the busted black or white line i found thanks to another thread... now i also found some dryrotted vacume lines that i replaced but there is also a thin black line that branches off that is broke it uses a rubber 90 boot to connect onto the tee ... now thanks to another thread i found where that line goes (over to the drivers side of the intake manifold where it was busted off there too) ill be going to the dealer friday to attempt to get a replacement ... now my problem lies in another line that is connected to the black line over by the intake manifold side by a clear connecting piece it is white and has a squirter like purge looking piece on it i cant seem to find where this goes ... took a few pics

this is the broken black line on the passenger side that im pretty sure runs over to the busted black line on the intake manifold


this is the white squirter looking purge thing that i found on passenger side jusying across the top of the engine


here is the line after it came off engine while i was trying to trace it the black line in the red circle connects to a canaster like piece on top on the intake manifold but i cant find what plugs into the white lines side


now this pic was taking from the driver side with the dog house off (which was a lot harder than it was on my 89 but still doable) the orange circle is the canister on the intake manifold and the green circle is where the black line broke off of


thanks in advance and remember the white line is the only one im clueless about what plugs into

well the dealership parts counter was no help today after looking through a couple of fuel related diagrams they said the part doesnt exist even though i told them it was AC related and to just use regular vacume line ... what a load of crock ... then proceeded to tell me i could bring the vehicle up there to have one of their techs look at it .... ummm no they didnt even try to help they are just trying to hit me up for a tone of cash since astro vans are expensive on the labor prices ... if the line is on the vehicle it exists ... any suggestions on this issue? do you think regular vacume line would work?

[trickedastro99]

fixed .... the white purge looking valve i still cant figure out where it goes but i by passed thats with a piece of vacume line with the hard plastic line and 90 connector on each end so the AC is blowing right again ... thanks for all the help matrix

now to install my CD player, amp kit, and sub yay! time to search on hints on getting the consol off to install kit

I have this line capped off because it was not attached and my a/c only blew out of the defroster. It blows from the vents now. It is getting vacuum from the the fwd, drivers side of the intake manifold and supplying the a/c unit on the top passenger side.

I don't see where this line that runs down goes. It is going to be hard to get to!

[trickedastro99]

the vacume line come off a canister on the driver side intake manifold i believe it is part of the PCV system it will have a line coming out of the valve cover and going into the top and on the front side is where the vacume line comes out ... you can see it very easily with the dog house off ... from there it runs across the top of the engine to a T fitting ... one line goes to the firewall and the other goes down to a round ball canister ... if you cant see the round canister just pull out you water resivoir and you will see it then just stick your hand down in there and feel around the top back till you find a nipple (just imagine your trying to grope a *** for your first time ) anyways back on topic lol those are the three points on the system

DOH 'my best Homer Simpson impression' I should have figured that reservoir is the easiest thing to remove.
I guess it acts as an accumulator for when the engine vacuum drops. The system is working normal now but I haven't had a vacuum drop condition either. The wife drives it more than I do.

Thanks

I had the same problem awhile back. The vacuum lines goes across your intake manifold and plugs into your cruise control system on the rear driver side of the engine. I plugged it back up and my air blows out of my vents again. Hope this helps.

There is also a line in that area that goes to the heater control valve, located low on the side of the a/c housing.

I broke my black hose right by the rubber boot. when i just changed my compressor. I must of broken it while reinstalling the fresh air ducts to the fuel injector. I fixed it by duct taping the hoses back together. My ac now comes out of my vents, instead of the defrost. that only lasted yesterday due to the heavy rain.
