2000 E350 AC Problem

On my E350 with V10, when accelerating with AC on, the cold air switches from the dash vents to the defroster vents. I've read that this is likely due to a vacuum-related problem, possibly a broken line or reservoir. Where can I get a vacuum line diagram for this year van?

Thanks.

See if there's anything here you can use: E-Series HVAC Vacuum System

Also another member here posted this video which offers another way to easily re-route the vacuum signal inside the cabin: Vac System Its a bit lengthy but interesting none the less.

Thanks for the link. Here are some links to some YouTube clips that show a work around to replacing the vacuum reservoir, which seems to be a likely culprit. Maybe these will help, too.
