Need help verifying HVAC vacuum lines on 3d gen wagon

[SmashedGlass]

In the process of reassembling the interior of Lé Sube, and I'm a bit confused by something I noticed with my HVAC vacuum lines. I was careful to tag them before removing them from the mode panel but now I see that the numbers on my tags do not match the numbers printed on the hoses at their component ends; perhaps the PO switched them around and I failed to figure this out before hand?

So, what I would like is for anyone who has access to a late model GL (with a/c) that is disassembled enough, to trace the four lines from the mode panel to where they terminate at their components.

 

This is what I am looking at, on my '88 wagon, with all four lines currently disconnected from the mode panel, going by the numbers printed on the rubber hosing at the component ends:

 

#1 plugs into the servo on the blower housing 

#2 plugs into the upper servo on left side core housing (servo angled @45 deg)

#3 plugs into the lower servo on left side core housing (horizontal servo)

#4(not numbered) runs to the upper left firewall and then to the vac canister in engine bay.

 

The way they were apparently connected at the panel when I pulled it and tagged them:

#1 hose was tagged as and plugged in at #4 on mode panel?

#3 hose was tagged as and plugged in at #1 on mode panel?

#2 hose tagged as #2, and unnumbered line to firewall left untagged.

 

Thank you in advance if anyone can help me on this.

hi,

 tried looking this up in the 88fsm, they only show the vacuum hose layout in the heater section, "and list USA models"  and  "canada models" ..

  the USA chart is shown using colors to identify the locations,  do you have any color ID  to work with on your mode panel, either the plastic tubes or the rubber hoses or in print on the hoses anything indicating color id??   book shows , white, red, yellow,  and a 4th one no color id  is the one goes to the firewall and to manifold vac,  it also has a one way check valve inline shown inside the vehicle, ?    i have one in engine bay side, don't know if there is another..

   from the mode switch panel,,  the white id hose is the one going to the 45 degree vac thing up high on the left,,   red goes to the other one, horizontal on left.. 

 both the white and the red are shown to go into some sort of "connector unit thing"  its not identified in the book,, before they get to their designated vac units.

   yellow is the one goes to the vac actuator that works the internal / external air flow, is mounted on the blower case.

 

  the canada model cars use a number id ,  white is 1,, red is 2,, blue is 3,, but the routing and vac units  for them is fairly different  from the usa layout.  the horizontal vac unit has two hoses, red(2)  just like usa,,  but blue(3) out the other end.  the 45degree unit gets white(1)  same as usa.   the main difference is they have a air inlet control switch "teed" in,, it is the line from engine vac , and the T  is  before the mode switch.   one side of the T  continues  on  to the air inlet control switch,  the T side goes to the mode panel,, blue (3)position,,   the air inlet control switch has 2 connections,  neither of them is marked as to which is which..   one comes in from the T and the other goes to the blower case vac actuator unit, no color or number shown.

 

 maybe this can help some

Could you scan the relevant pages from that '88 FSM for me?

hi,

   sorry i dont have any way to do that,  maybe someone can, i thought we have a fsm on the board someone scanned the whole set and is available , not sure on that.

 anyway , take a close look at the little rubber hoses that are on the mode control, they are about 2' long to my memory, and used to connect to the plastic tubing,   seems i remember they have a color stripe on them or a number printed on them, been a while but i know there was id on the stuff.   also the same for the vac unit connections, the actual pipes are plastic , the little hose connectors are the ones.

 member suprjohn just got through going through his entire system, maybe his memory is fresh.

Yes, the short hoses on the mode panel are numbered, as are the sections of hose at each component. The issue on mine is that I tagged them as I pulled the plastic hoses out at the mode panel, but now, tracing each tagged hose to it's end at each component, my tag #'s do not match up to the hose #'s at the component.....leading me to believe the PO had pulled the panel at some point and plugged them back up wrong. But the numbers on the component ends, if matched to the hoses on the mode panel, also do not match up to the few diagrams I've found. I did find another old post where (I believe) the poster found that his hoses were routed the same way as mine are numbered, which leads me to believe.........THE FSM IS INCORRECT?!?

 

As a note, rupart, that FSM available online is only the engine and transmission section, AFAIK.

Dang it just had my dash apart, but I do need to get in there this weekend I will snap some shots if you still need them but my numbers matched the vacuum housing I remember looking at it and the blank one crap I can't remember.

But I know this thread had pics and details of taking them apart and putting them back together, problem is pics expired but might work incognito on chrome something about the pic account. Thumb through it see if you can see them if not I will see if you still need them when I take my dash apart once again:)

I'm familiar with Jezek's threads on the LED lights and what not. All his photos show is the mode panel, he doesn't trace them down and show where they connect. Of course, wouldn't expect him to if his thread is about light bulbs
