    Default 1992 pontiac sunbird L.E. AC vacuum system

    Can someone please tell me about the heater and A.C. vacuum system controller in a 1992 Pontiac sun bird? I think someone may have crossed the vacuum lines that control the air ducts on the heater box. There are 3 vacuum control canisters under the dash board with color coded vacuum lines, How do I find out if they have been crossed??? I do not have the manual.
