Have had my 2008 for 3 months now. When it is 85 degrees outside, the air blows like an arctic blizzard. When the outside is 90 or above, the air blows cool, not cold and will not cool down the car even after several minutes on Max Air. System is fully charged and has been thoroughly checked out by a competent shop - everything is working correctly. I know a system has to work harder in really hot weather, but at these same temperatures, the air in my 2005 Caravan (front only) is like a walk in freezer. Do I have to settle for only having air when I really don't need it?
