After driving for an hour and a half or longer, the a/c or heat (depending on what's on at the time) stops working. The fan still blows but doesn't blow hot or cold air. Took it to the dealership and they said they couldn't do anything because they couldn't duplicate the issue. This happens when I'm using the ATC or manually controlling the temp.

humidity and the a/c doesn't cool off for a good fifteen mins. I live in Florida where the humidity is well over 100 degrees and when I have someone in the back seat and cannot control the a/c it is a real pain. the a/c only will blow out cool air when it is on auto.
