Your problem is that your BCM (body control module) is bad. A used one can be purchased for about $70. To install the BCM, take out ONLY your glovebox. Located right behind the glove box is the BCM, its as easy as unmounting it and unplugging the chord and plugging it into the new one and remounting it. 10-15 fix max.
