2004 Grand Prix GT. I started my car today and began driving down the road. Only to find that my HUD isn't on. I turned the switch and it was on. I thought maybe somehow it got moved up. It was so I pushed the down button and it didn't move at all. It will not go up or down. The switch is still good because when I press it it puts the edges around the outside like it normally would. I don't have a clue what is going on. Help please!!!!!
