The charge, pressures all at spec, the auxiliary fans are working properly, the interior sensor ok, climate control unit system ok.
When the engine is at idle, the ac blows warmer air. Ambient temperature 85F, system set at auto, max cool, when driving, the air temperature at center vents will average 42F (nice and cold). Then when at idle the temperature will climb to 58 to 60F in about 10 minutes. Upon initial start-up the air will cool down to approximately 60F at the center vents, and once driving the temperature will drop into the forties in about 5 minutes.
What do I check, puzzled, Thanks Tim?
