My Ac is not coming through the proper vents. I am led to believe I have a vacuum leak. I did some checking today..
Is it likely that the line in the engine compartment (outside the car) is more likely to have failed than inside the car?
The lines in the engine bay are exposed to weather etc..Is it safe to assume the problem is with the line coming in through the firewall?
I could put in a new line and cut & T-connect into the line going through the wall so I do not have to reroute that part...at least for a fast fix.

Any help or ideas as for which lines could be affecting my vents in AC and heat..as I say, the lines inside the car are not brittle.

 

Hmm..lots of lookers and no advice. Well I am going to go at it.
