Well yesterday I received my HUD kit form GM Parts House. I decided I couldn't wait and started on the install. I worked late into the night and finally finished.

At first, everything worked just as it should. It was great. I went for a short 20 minute drive and everything was fine. Then.....

As I was pulling into my parking place, the instrument cluster lights and the radio died. I shut the car off, hit the ignition button and as soon as it fired the engine died as did all interior accessories including the instrument cluster, doors, windows, radio, etc. If I turned the radio on, it would light up and display the time for about 20 seconds and then power off.

I then pulled the gauge cluster bezel with all the switch wires. As soon as I popped it loose most everything worked as it should. Now the only things that don't work are the HUD and the range reads LOW when i have half a tank.

I assume the HUD doesn't work because I can't see it. It is ultra bright daylight out though so I'm not sure if it should be visible or not.
The battery was unplugged just as it should be for the entire install.

The only issue I had with the install was that the ground wire was too short and pretty tight pulling on the hud switches but it loosened up once the bezel was in place. Since everything worked at first I'm not sure what the issue here is.

Any ideas or help?

 

HUD is bright, even in daylight. With everything dead...look for a ground problem.

 

The thing is, everything is working again, except for the HUD....

 

I'm not familiar with the unit if there is a fuse or something but check to see if it has its own fuse and start there in case it popped one. Also kind of off topic but how long did the install take? I have a HUD but need to disassemble mine because the bracket (Or whatever holds it) is loose and it wobbles on bumps now.

 

cluster lights and HUD are on the same Fuse.

Give me a call.

1. Press the "+" button to adjust your HUD to max brightness. Then use the up/down button to cycle thru the height adjustment.

After I installed my HUD, I tried fob #2... long-story-short, I believe there's a memory or default or something that might've changed your initial HUD adjustments.

Anyway, it's easy to adjust the HUD, so try that first.

2. Check the CLSTR/HUD fuse in the passenger footwell.

3. If you still can't get your HUD to work, unfortunately you'll probably have to check the wiring.

4. The too-short ground wire you described might've pulled almost loose during the install... then dislodged during your first drive.

5. If you have to remove the IP again, might as well double-check all the wiring connections... much easier in good daylight.

Whatever the problem, I'm sure it's fixable.

 

It took me about 12 hours over two days to install a HUD in my 09 1LT. That includes trips for parts & tools, meals, breaks, triple-checking everything, etc.

It would take less time to replace an existing HUD because you don't have to splice-in new wiring.

An experienced installer like Andrew can replace a HUD in an hour or so.

Shaky/wobbly HUD image is not uncommon... it's caused by a broken plastic pivot pin. Lots of threads on this topic, like these:

Just call Andrew.It's what he does.

 

I pulled the instrument panel to check the wiring and what I found is that the short ground wire had loosened the connections on both plugs into the cluster and the plug into the Hud. I spliced in a section of wire to lengthen the ground, plugged everything in nice and tight and she works like a charm now.

If anyone orders the kit from gm pars house, just go ahead and lengthen the ground wire! It really needs to come longer in the first place.

Thanks guys!

The install took me 5 hours from start to finish. Not too bad, just tedious and rough on my hands.

 

Glad you got it fixed.

And it scraped my hands pretty good, too.
