2022 At4x Heads up display issues

Rockyah86 · July 2, 2022

Hello everyone,

Need help. 2nd day I owned new truck, heads-up display started to become glitchy and would shut off then come back on. It would have colored vertical lines all over the place then half of the speed would show then shut off. Then it would come back on for a while then shut off. Any ideas? I have an email out to dealer but waiting for response. Too me it seems it could be as simple as a loose connections somewhere. I can't find anything on this truck since it's so new. Any suggestions would be appreciated.

Other than appearance, fictionalized your truck is no different than the 2020+ trucks. Dash probably comes apart the same way, too. Issues happen in manufacturing all the time. It's a holiday weekend, so they'll likely be closed Monday. This isn't a drivability issue, so don't expect a loaner while you're without your vehicle.

I have a refreshed truck too. If you want to get to the dash speakers or the HUD module you just need to remove two bolts on each of the grab handles(passenger and driver) and pull out to remove the A pillars, then you can pull on the cover trim on the dash, pull straight up, clips only, no screws on the cover(long piece so be careful not to scratch anything with it). I'll try to find some pictures for you, but it's really easy to remove...

Can't really say its "no different." AT4X dash is all new as is the SLE/SLT dash, neither are the "same" as 2019-2022. Low trim get the old dash. The 2022.5 are on the all new GM VIP (Global B) electrical architecture so many modules are all new compared to 19-22 which is Global A. HUD parts are all new #s as well.

Manny Man,

Is there any way you can show pictures of what to do to remove the refresh dash area to get to the dash speakers? I want to replace my speakers but not 100% sure on what area needs to be removed. I would greatly appreciate a visual reference.

Hey, sorry for the delay.

here are some pictures of the piece that you have to remove. It’s just one piece, stretches across the entire dash and held on with clips.

as I said before, there are some tabs that extend into the A pillars so you’ll have to remove them in order to lift this piece straight up and remove it.

there are two bolts on each of the grab handles that you have to remove and then you just pull outward on the a pillar. Pretty easy job, you can’t really mess it up.

Rockyah86 I am having the same HUD issue as you described on my 2021 GMC Sierra 1500 AT4. I checked all the IC fuses and they all looked fine. Did you end up fixing the problem and what was the solution?
