Thread: Problems with my heads up display. 04 gtp

Ok so about four months ago i got into my 04 gtp, and noticed that my heads up display was no longer displaying. a while later I started cleaning out my car and noticed that it was in fact still working but had some how managed to get all the way up to the top of the window, or as high as it would go. I tried to hit the button to bring it back down and for some reason it seems to be the only button on that console control that doesn't work. Every other button works just fine, except for adjusting the height back down.

I took it to the stealership and they told me that since i have a after market stereo that it caused some sort of voltage spike that fried the heads up display unit. but it all still works except one button. I have a back ground in Electronics and have been an Electronic's technician in the navy for 4.5 years. Everything i have learned tells me that this is impossible. And I don't know where else to turn for help. Stealership wants 850 bucks to fix it. Any help?

Hi John, The exact same thing happened to me yesterday! I got in my car and my HUD was gone. After closer inspection i realized that is was up to high to see. Have you figured out how to fix the problem?

I found out what the problem is and how to fix it! Apparently there is a small spring that connects to a plastic piece on the HUD. Over time the plastic may break leaving the spring lose in the hud. To fix it, take out the HUD and drill a new hole in the plastic for the spring to connect to. This should fix the problem.

Can you be any more specific please? I really want to do this but I got to get it right. Can you send some pictures or a little more detailed. Thank you

Yeah, I'm wondering how exactly you did it because I'm facing the same issue. Any help would be appreciated. Thanks.

Here is a quote from an article I found:

"Pontiac Heads Up Display problem
I just fixed my wife’s heads up display in her 2004 Pontiac GT2. I thought it wasn't working, but realized that if I slumped way down in the seat and looked through the steering wheel it was projecting. It was just way out of line.
A close up look through the front windshield showed a loose spring in the display. When I rocked the car, the spring moved freely. I took the dash apart and pulled out the Heads Up Display. Upon opening the HUD I noticed that the small plastic piece that held the spring down was broke. I drilled a new hole in some plastic nearby and connected the spring. I put everything back together and it worked perfectly.
It took me about two hours to remove, fix, and install, but i work on cars often. It was a lot easier that I thought it was going to be."

Alright what rianna is saying is true. I plan on tearing mine out of the dash this weekend and i want to take a bunch of pictures and do a write up on it to post here on the forums. from what i have seen its a horrible problem with a lot of the heads up displays that are pretty easy to fix. Just hard to get into. Any who if you have any questions pm me. And hopefully in the next couple weeks keep your eyes peeled for the write up.

Thanks for the responses. Looking forward up your write-up on it too.
