My buddy has a 2008 grand caravan SXT 4.0L and the rear ac only blows warm air the front left and right sides both work fine the rear blower blows fine but no cold air the compressor runs constantly and does not cycle and when I hook up my guages the pressures are 40 on low side and 375 on high side with outside temp at 90 degrees and 72 percent realitive humidity so everything in that aspect seems ok (as compared to my 96 GC) I was wondering if there is a heat-cooling door that isnt working or if there is something that restricts flow of the refrigerant to the rear evaporator or if there is an electrical problem im just not that familiar with the newer vans on how they work so if someone could point me in the right direction I would sure appriciate it thank you Mark
