I have a 08 Ltd with auto dual climate system. That thing seems to have a mind of its own. I don't like to keep it at Auto as it does not heat windshields at that setting. So for now I will use it in Manual mode. However occasionally, this thing goes back to Auto mode, when I restart the engine, without me touching the unit. Also, in manual mode occasionally A/C starts running, when you restart the engine again. I am tempted to say it resets itself after an engine start, however it is not doing all the time.
