The ac is confusing. Ac will come on automatically even when the switch is not highlighted and it is not on auto and it is hot outside. In my car you have to press ac to turn on and then again to turn off for the ac to be manually off. Ac is off only when there is a line on top of the ac button that is not highlighted and is grayed out. If you see the words ac on the screen and no grayed out bar on top of ac that means the auto ac is on and that is why you get a puddle even when you think ac is off. It is actually onAnyone know how to get the A/C feature to automatically come on and stay on?
