AC front/rear problem on 99 Tahoe
My friends Tahoe is blowing cold AC in the rear.......but not in the front.
Dial is set correctly in front. Any thoughts?

Re: AC front/rear problem on 99 Tahoe
Does it blow at all up front? If not he may have a fan issue.
Does it blow but not cold? If so he may have a blend door issue and it is stuck with some heat on. Also check refrig levels. I don't remember how the refrig lines run, but I wonder if a low charge is making the comp cycle and the rear is pulling the larger load or getting what little may be avail.
