So today I discovered that the switches on my dash (for the blower fans and rear-defroster) don't all flip in the same direction. It's always something... Not surprisingly, the owner's manual does not specify which direction that they are supposed to flip, and now that I think about it, unless one had access to a known original car, how could one know for sure? So what do folks think? Should I make them all flip-up. or flip-down?
