Exclamation Vacuum leak help

Have a vacuum leak that leaves the A/C only running out of the defroster vent. Tried to listen for the leak, no good. Tried inserting a can of Refrigrent+ red dye, still can't find it. The thing is though, I don't know where all the vacuum lines are/ go to. A diagram would be awesome, also any ideas on how to find it.
Also, would a vacuum leak cause a rough idle?

I need my A/C ! ! !
thanks

Mike P.

Not sure what exactly you are saying, but a quick way to find a Vac leak in the motor is with wd40 or carb cleaner. Simply spray lightly around suspect area, if unknown most all vacuum lined originate from the plennum/TB area.

There are a lot of things that can cause that, but yes, that is one of them.
