Hi all, My 2011 599 A/C is not blowing cold. I checked the pressures and they are within range. When I was driving the car with the recirculation button off and the temperature level set to low, I noticed very hot air coming through the vents. I suspect the A/C (cold air) is being mixed with the heater air (hot air) making the combined outcome warm air. Has anyone had this issue with their 599? I suspect the heater valve is not closing all the way. According to the WSM, the proportioning valve goes through a learning cycle whenever the battery is disconnected and if the leaning cycle fails it repeats the learning cycle whenever the cycle is cycled on. I have cycled the key several times, but the result is the same. Any ideas what the problem could be?
