2010 Prius purchased today Ac button refused to work. It will not light up under any circumstances, thus it blows warm air out of vents even if climate is set at coldest setting. I can however get freezing cold air to pump out of the defrost vents if I hit the front defrost button. When I do this the ac button light does not illuminate however. I have verified that the ac button light works by doing the trouble code sequence (0 codes shown). Anyone have any experience with this? Thank you so much in advance!!
