I think my car has somehow developed a vacuum leak...last year the air conditioning worked, the cruise control worked, and the heater direction switch (defogger, vent, etc.) worked...now none of it works. I'm trying to locate where the vacuum main is so I can redirect it to a new line I will install on my engine...If anybody can help me with this problem, it would be greatly appreciated. Thank-you in advance.

If you remove the switch, the main line in will travel through the firewall to a vacuum supply on or near the engine.
