Hey yall, has anyone here had their rear expansion valve fail for the a/c? I have an 03 with the 5.9. I got the durango about a week ago so today recharged the ac system today since it was flat. I pulled a vacuum, and weighed in the charge and the front is blowing nice and cold, but the rear is still warm. I took apart the rear climate control box and i can tell that the evaporator is not getting any refrigerant flow. Im suspecting that its the rear expansion valve. Am i missing something? Is this common?
