Hi, I purchased a 2000 Expedition and I have a couple problems with it. The ignition key chime stays on when the driver door is open, even tho the key is not in it. Also, the cruise control does not work. The cruise light doesn't come on when you push the button or anything. Truck had previously had the turn signal lever worked on as the teeth on it were not engaging correctly. Does anyone have any suggestions on where to look to solve either of these issues?
