Even with the A/C blowing full blast in manual or auto, the rear vents for the rear seats just blow a wisp of cold air. The temp. is not the problem but the amount of air seems rather light. I'm trying to qualify just how much air should be blowing out. I rode in the back seat of my bosses truck (not a Dodge) the other day and the air volume out of the vents was at least three times as much.
