Subject: A picture is worth 1000 words A.K.A. Vacuum problems by 84Xfire on 2013/5/24 3:21:49 I hope one of the "Guru's" on here can help me sort this mess out. I'm trying to find out why I've never had A/C from the vents, and it really is a mess under the hood. The photo might help explain better just what I'm dealing with. The upper left circle is the first 2 connections for vacuum; the one furthest back is going to the PVC valve and I think that's right, execpt there should be 2 connections there instead of one (the part that should be there looks like the letter "F" for lack of a better description). The second connection is for the brake booster; that part is fine. Here's where it gets weird.... The accumulator(ball) is connected to the cruise servo; that's all (cruise hasn't worked in a long time and I wasn't too concerned about it as I don't use it). there's a "tee" by the bottom of the ball with the short end capped off (QUESTION: wouldn't that capped off part of the tee be going tword a vacuum source like that "F" adapter in the upper manifold?). Now, to the passengers side. The split loom that carries the pressure cycling connector and the water control valve vacuum line (1/8" black tube) has another 1/8" black tube coming up that's in the lower circle. I found it when I changed the plugs and wires and I pulled it out for clarity; I have no clue where it goes. Possibly from the missing check valve it's suppost to have on the passengers side and it doesn't show in the FSM or the suppliment, so my next QUESTION: where would it go and where would it draw from a source? I do know that the crankcase vent on the valve cover should be hooked to the bottom of the air cleaner, so onto a third QUESTION: what is the forward connection supposed to be connected to? Thanks in advance for your thoughts on this... |
