After about a week of not driving the car, and probably not having the rear hatch fully closed, the battery died. I recharged the battery, but four of the pushbutton controls (rear window wiper, washer, plus, plus, on the center to the lower left of the radio/CD player) small lights come on whenever the engine is running, but not when the engine is off. What can I do to get the button lights to function properly? (I suppose to not be on whenever the function the button controls is not on. By the way, all the functions work normally.
