Ok here we go again. My rear a/c blows from the top, like it should. But its hot. I have checked the a/c lines into the rear unit and they are cold, well one is cold, one is hot. Acctuator is working to put air to top vents. Front vents cold. Put guage on low side and its about 65psi(guage is one of those you get to recharge system from AZ). I have run out of ideas where to look and the kids are tired of baking when we go for a ride. Any ideas would be appreciated greatly.
