Blacked out dashboard

15 denali · December 17, 2019

I’m having a issue with the dashboard not coming on not working what so ever . Speedo and rpm gauge not working and the digital display not showing up and also my radio blacked out as well plus steering wheels controls are not lit up . But everything else seems to work fine . Even my backup camera comes on in reverse it’s very odd to me so if anyone could help I’d appreciate it deeply .

Welcome to the site.

My guess is your HMI module is going bad. Taking down one function at a time.

So it that will cause all that stuff to not work. Or that just for the radio? I just wondering if it’s a fuse or something .

Believe it controls most/all of the electronics associated with the dash.

There are some post on here about the same/similar problem.

Could lead me in the right direction cause I really shouldn’t be driving it until it fixed and I’d like to do what I need cause I have no idea what’s going on and I just got the truck about a week ago and haven’t even drove it but once . And I appreciate your help

Yes sir.

I would do some research and see if you can upgrade to the current version so you can add CarPlay, if that is really the problem.

Well I have figured out the issue I’m sure I put in some aftermarket leds headlights bulbs and well I decided to remove them just to see and put the factory yellow bulbs back in and got up this morning and opened the dirt everything is working completely fine . That’s just crazy . So now I have to do some research and get some actual led bulbs that won’t effect that problem from happening again .

That is good news for the holiday's.

Search around on the site to find a brand of LED's that don't cause adverse electrical effects and you should be fine to run them.

Merry Christmas!!!

Post a picture of your dash, so we can see what you are describing.

Do any of the lights on the gauge cluster work?
