AIR question

Hey all, i went ahead and deleted my AIR system finally, and now my dash vents dont work. Is there some vacuum line i missed getting capped off and if i did where would it be? Thanks

The blend doors are vacuum actuated. You most likely removed or capped off the vacuum source for the HVAC system. A factory vacuum diagram will show you which line was for the HVAC and where it's vacuum source came from.
