Key switches are weird & are wired different ways -- for example, while the radio will work in my truck with the key in the Accessory position, the power windows & locks will not -- have to turn the key to the On position for them to work. I've had other vehicles where everything electrical would work with the key in the ACC position & a couple where just one thing wouldn't work whether the key was in the ACC or the ON position! And it turned out to be the key switch itself, not the item that wasn't coming on.
