joelattanzio@comcast.net 07-23-2008, 05:37 PM Does any one know if the a/c suppose to come out only through the defroster and heater and not the vents ? If I leave the a/c on for 15 minutes it eventually comes the vents . Is this normal ? DRMZO7 07-23-2008, 05:41 PM I believe that is the default position. You either have a problem with the a/c programmer or the vacumn valve located under the pass/side fuel rail cover. You can check the valve under the cover easily. They tend to deteriorate over time. The programmer is a different story. Fortunately I have no experience with them. Someone will come with help for you. SAYWHEN 07-24-2008, 04:38 AM I believe that is the default position.

(meaning it sees a fault)--If not my first check would the vacuum check valve and/or hoses under the fuel rail as stated above--it's a easy check and a fairly common problem.:driving: | |
