If this is the case, it is azz backwards and FCS needs to rectify the situation. Max a/c should always be quicker to cool as it’s supposed to recirculate inside the cab. My father n law never could grasp that concept, for whatever reason. I realize this is common knowledge, but it irks me how so many details/ flaws are overlooked/not fixed, in these overpriced trucks.I've found my a/c works best by NOT using the MAX A/C selection. I lower the temp all the way down and it seems to cool better.
