HVAC Vacuum Leak
Have a 2000 Vert with a vacuum leak behind the dash when the system is off. When I turn the system on, you can hear the blend doors move and then the vacuum leak stops. All functions work as they should, just vacuum leak hiss when system if off. What am I looking at to repair? I am guessing that there must be a vacuum motor that has some kind of leak only when the system is off. Will the dash have to come off to access the vacuum motors?

Yes the dash has to come out. Here is a thread with pics of the HVAC unit and vac lines.
