My heads-up display on my 04 grand prix gtp went out! how can i fix this?

I've had to fix both of my HUDs on my two 2004 Grand Prixs. Look down low through the steering wheel to see if the display. Hopefully you can. You can also look through the windshield at th HUD unit. Look at the tension spring and see if it is loose. The problem on my cars was the spring wore through the plastic lever that controls the reflection angle of the HUD. If this is the case, you are in luck. Remove the A-pillar moldings by simply pulling them off. You must then pull up on the plastic dash molding that encases th HUD and runs the entire width of the dash. Remove the screw on the far left side of the dash by your left knee. Pull out the plastic arch molding over the instrument cluster. Unbolt the instrument cluster and pull out enough to get to the screw that holds in the HUD. (There are two screws, one in front and one on top.) Pull out the HUD and unplug. Carefully take the HUD apart. Get some good epoxy or JB weld and fix the plastic lever. You must the drill a hole for the spring or poke a hole through the epoxy as it is setting up. I let mine dry overnight before re assembling everything. The task may sound daunting, but it is not. You should be able to get the HUD out in 20-30 minutes. Hope this helps. Everyone should place sunvisors over their HUDS ALWAYS!
