I just spend a helluva long time cursing and fuming as I repaired some "fixes" the DSPO did behind the heater controls. Everything. Now functions as it should and all doors operate correctly. Alas, still no air at all out the actually VENTS. What the heck?

That looks like the one!! Thanks! I'll take a crack at it again tonight

Thanks, but I need a diagram showing the vacuum setup for the heater control box, not the engine bay

Hey guys, I scored my first MJ this past weekend and as usual, it has vacuum problems. It's an '86 with a 2.8. The vacuum ball has been relocated to the passenger side fender under the hood and I have verified that the hose leading through the firewall is good. The heater control valve has been removed and I can't locate the vacuum line that came off of it to make sure it's plugged. I pulled the controls out today and it's a mess back there. The kid that I got it from "fixed" some hoses and I am almost certain he has aborted the whole setup. I really can't tell what is supposed to go to what at all. Anyone got a diagram or some good info for me?
