When first starting my 02 LC cold, I notice that the Auto setting does not work very well. I have the nav system so the setting is via the touch screen rather then knobs. The auto finally kicks in about 5-7 minutes after the vehicle is started - unti then the fan is off unless I set it manually. Is this a feature of the LC, or should the auto setting set the climate controls immediately upon starting the vehicle (in which case I am out of luck since I don't have the Platinum warranty
