What to do with the vacume lines after completly removing the A/C? Should I just block them off? I am leaving in the Fan unit on so I will still be using one line to the HVAC controlls but the rest I will not need. Any sugestions?

 

What vacuum lines? There is one from the back passenger side of the intake manifold for operating the flapper doors on the AC/heater system, and if you still have the fan, you might want to leave the vacuum system intact so you can still direct the air flow to the defroster. You could remove the small vacuum canister mounted to the frame rail inside the passenger side front fender.

What other vacuum lines are you concerned about?
