Well I don't remember seeing them before...but recently...couple months ago I had my ac repaired. I was not getting cooling and compressor was not comin on...plus outside air was comin in even with climate control off. They fixed that....but then it started happening again...however the ac works fine. I'm guessing that one of the vacuum lines is having to do with the econo meter and that the other one is somethin to do with air vents closing. Does this sound correct and if so, where in the tarnation should they hook up? I don't see anything out in open for them to connect to.
