Just noticed it this morning on my drive into work.  The air flow direction for the feet (don't know what else to call it) is blinking intermittently.  Is this something I can replace myself or is this a trip to the dealership?  I did a search online but all I can get is why the A/C light blinks and nothing about the backlight going out.  2017 GMC Sierra

 

Took a video of it also:

Welcome to the site.

 

Not an expert, but I have found if you stop the truck while weird things are happening, turn off the engine, remove key, and open drivers door, it will reset some issues.

 

One question is always, original battery? If so, you might want to have it checked out or replaced.

Or of course, you might just have a bad control panel that is going out.

Thanks!

 

Yes it's an original battery, didn't even think about it being an issue with it just being the one light only but I'll have it checked out regardless.

You are very welcome.

 

The trucks do all kinds of weird things when they have a failing battery. They are basically rolling computers now and need a consistent charge to function properly.

Ever find a solution to this?  Mine is doing this as well and the battery is not old or low on charge.

I’m having the same issue. I just replaced the battery about 2 weeks ago. I didn’t notice this until yesterday. It blinks for a few minutes intermittently or stays off for a bit but then comes on and stays on. Any ideas?

Mine is doing the exact same thing and it's extremely annoying

Needs a new HVAC control switch if you have the lights flickering on the buttons.

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
