2015 Silverado 2500HD LCD Center Console Display "Dimming"

Trailbreaker77 · May 6, 2015

Has anyone had the center LCD display in their dash dim during your drive? When I start up the truck everything looks good however by a half hour or so the display is so faint it looks off. I don't know if this has a daytime sensor or what but even if it does it is so dark it's not readable.

I called the dealer and they make is sound like I hit a switch or a knob that dims it down but I'm not seeing it. Anyway I was wondering if mine was an isolated case or if this is a common issue.

Thanks,

TB77

I can send you a PM but I don't know if what I'm experiencing it actually a problem or not.

Here is a photo of what the screen looks like when I start my drive. (Sorry it's upside down I couldn't get it to rotate.)

And here is what it looks like after the half hour drive home.

I've seen this on mine. I think its related to the DRL sensor. My 2012 would do it too.

Awesome! Thanks for the help I'll see if this is what my issue is.

If it does that roll the brightness knob left of the headlight switch. If it doesn't come back it's not likely the cause. But with all the electrical I've had,they aren't going to fix yours either, so don't get your hopes up. The warrantee is a game, if you happen to be able to make it do it in front of their eyes, they will fix it. Otherwise it's operating as designed. And customerservice will lie and mislead you, talk very rude to you, and after all that close your case with no resolution or inform you they did so.

yes, my 2015 2500 did it once, rotated the light dimmer knob up and down and it popped back up bright. No problen since!

This is exactly what happened they told me it was functioning as designed, I'm not really happy about it either.

Same here mine did it about a year ago and I did the same thing with the dimer wheel, never done it since.

My other 2500 HD just got sideswiped by a driver that fell asleep behind the wheel, so I went and picked up another new one from our lot, and it has the same issue. My other one worked fine, and I had 90,000 miles on it. This one has only 1000. I'm taking it to the dealer, but was hoping I would find something to point the dealer in the right direction. Didn't have too good of luck out of them on the Stabilitrak on the other one. Of course I can't really blame them because apparently any Stabiltrak codes are not stored, so they couldn't figure out what was wrong with it.

I also tried the dimmer wheel, it dims the dash lights, but does nothing for the display.

Ok, took it by the dealer last week, was able to show the service writer what it was doing, she is going to contact GM to find out the next step to schedule an appointment. Have not heard back from them yet, so apparently this problem doesn't have a solution yet.

Still haven't heard a reply from the dealer, it does appear to be related to outside light. The brighter the day, the dimmer the display. This didn't happen on my previous 2015. That's why I made the service writer look at it while it was doing it. Also it has the rough idle that my 2012 had, that my 2015 didn't.
