We’ve had some crazy cold weather here lately. The screen In my 2006 gs300 Lexus quit working. The radio still works, but this screen controls the heating and cooling and we cannot get it to come back on. Don’t want to drain any accounts taking it to a dealership. Was hoping someone may have an idea .... He’s unhooked battery cables and tried that. Didn’t work :( took battery to get tested- it’s good
