Question
I have a 1999 Chevy Astro passenger van. I was having problem with the AC not blowing air thru the vent. After much research on the web, I determined it was the problem with vacuum lines. I replaced the one coming from the "black ball" to a T connector, as I was doing that, the other line on the T connector basically disintegrated. I can't see where it was leading to except it's toward the firewall. I'm think about having all of the vacuum lines replace but I don't know where they are and how much effort. A vacuum diagram may help me determine if I should just go to the professionals.

Answer
Dave,
  Most GOOD Public Libraries have a "Reference Section". You cannot check out the books in this area but you can photocopy whatever you need. MOTOR'S produces a manual called a "Vacuum & Wiring Diagram". This should have the information you need. IF you don't see it, ASK the librarian. Maybe there is one in the Library System, just not at your branch. Maybe they can have it shipped in from another Library.
  If that doesn't pan out, go down to your local GM Dealership and ask if you can photocopy their book or, if they tell you everything is on computer, ask for a print out.
  IF I had a copy of a 1999 book, I'd give you the photocopies but I do Auto Parts specializing in Antique/Hard to Find Parts. I'm NOT a Tech but I don't think you need one to answer this question. NOW, if you want to know how hard the job will be, THEN you should ask a Tech. Thank you for your question.
