1998 E350 AC Vent Switch and Vacuum problem
Air only blows out the defrost vents. Have remove dash panels and AC switch. There is no vacuum to any of the lines to the switch. Blend door appear to work fine manually. I can't seem to fine the supply line for vacuum. There is a small black line running through the lower passenger firewall area that appears to come from the engine compartment. No vacuum on that either.
Question:
What and where is the vacum line that provide vacuum to the AC vent switch?
Is there some kind of relay that is tripped by the switch that sends vacuum to the switch to be distributed?
Thanks..

You are on the right track- just follow that same line under the hood; probably goes to a plastic vacuum storage tank and to a junction "tree", then to the intake.
You might try posting in the HVAC section if you are still stuck.
