Hi - hoping someone can point me to a vacuum system diagram for my 01 v10. I can spot at least two lines that are either disconnected or broken (manual hubs responsible for one of them). It also appears that the vac pump isn't running.

The reason that started me looking at this was the HVAC vents blowing only thru the defrost vents, no other symptoms. What I would like to do is go thru the system, line by line, so I can understand how it works and trouble shoot it at the same time. A schematic or diagram showing the vac tubes, accumulators, pumps would be extremely helpful in doing this, so back to my original question - can anyone point me to such a diagram (hopefully a free one).

Thanks!

 

Start by looking under your hood for the diagram put there at the factory. Check the passenger side valve cover, the upper radiator support, and the underside of the hood.

 

Thanks for the tip but the diagram mounted on the vehicle doesn't have all the vac lines shown nor does it get down to the detail I need. Woulld really like to see the diagram out of the FSM.

 

You're not going to find anything more in the WSM or EVTM.
