You could take your ignition swtich out and see if the tab on the end of the cylinder is broken. There is a pin you push in. It is very small, and if your looking at the ignition lock from the passenger seat, it is at about the 7 or 8 O'clock postion. With the key in the run position, you can then pull the cylinder right out. If that is not the problem, then possibly the rack and pinion have slipped. There is a little gear on the end of the part that the lock cylinder turns, which moves a rack (which is a flat bar with gear teeth on it). This is what actually moves the electrical switch down below.
