My heat only blows warm on passenger side and ac only blows cold on passenger side. Doesn't matter if I have it on the upper vents or floor vents. Doesn't matter if I control driver side, passenger side, or both. Doesn't matter if I set it to auto, or manual.
It was working great until I got it back from having the tranny rebuilt. I know the tranny has nothing to do with it but, could they have knocked something loose somewhere?
Any ideas would be appreciated as it is starting to cool off and the heated seat only helps some. Thanks
