Help wanted HUD

My '00 GP-GT has the HUD, but does not work, i already check all the fuses according to the owner manual, but still does not work, does anyone has any idea on what else to try or how to test my HUD, and just in case i need to replace it, are they expensive?

Usually once or twice a month their on Ebay. Currently a whole setup on there right now.

i would check your HUD switch! I was changing the colour of my bulbs from red to blue! when i did this i had to take apart the HUD switch! when i put it back together it wasnt making an internal connection so i took apart and adjusted the metal prongs and than my HUD worked again
