Alright so I'm having a hard time finding the right information on my HUD. Got in my car today after work and it's not lit up. Was working fine about 6 hours earlier. I can hear it moving but after having my brother sit in the car and move it up and down I couldn't see it moving but looking down the tunnel I see no light even in my dark garage. So I'm thinking it's the bulb. What do I do, I have no choice but to try and fix it myself because we'll I'm not paying tons of $$ for labor charges. So If it's the bulb how do I fix it? Can I? Or is it a full out replacement of the unit. All responses and help would greatly be appreciated. By the way it's an 04 grand prix gt2.
