Hud Display

One of the few problems on a car that I would guess is not easy to figure out.
The HUD on Grand Prix GXP's is a different version so other than the entire unit burning out in some way I'd guess there is not a lot of similarities.
Good luck with it though.
turn your hud on at night and look through the windshield down at the hud. if you see green then the spring broke off.......
