Well after 2 years of problems with the 8"touch screen on my 2017 gmc Sierra I have finally fixed it🤞  it would randomly change stations and flick icons as if you were touching the screen, hours of investigating poor earth's and low voltage as suggested on various forums but to no avail,  my truck is a personal import into the UK so no dealer back up here I decided to remove the screen  and disconnect the touch digitizer from the screen by unplugging the brown ribbon cable  put the screen back in the truck and everything worked OK, obviously the touch doesn't but I could use the buttons below to navigate the screen and radio icons so all functions now worked without any problems,  after driving for a few weeks with no problems I was confident that the touch digitizer was the cause of the original problem, ordered a new one from China as GM buy them from there just $239 plus shipping  for the screen and digitizer as I didn't fancy trying to remove the digitizer off the original screen, a week later it arrived now installed and working perfectly 😀 Thought I would share this as I didn't think it would be such a cheap fix,1723329220_Screenshot_20220125-192258_SamsungInternet.thumb.jpg.99737cc6b42db9f9ce15ea21ea60f3fa.jpg

Yes install was very easy just need to be careful with ribbon conecters and the cable plug pins that go through the rear of the screen cover took less than half an hour,  when my problems started they were very intermittent and always cleared if I stopped the truck for a few minutes and restarted but became more frequent with time

i offten wonder if the bezel that covers and surrounds the screen where to touch or rub the screen by fitting too tightly, would this be the cause of the erradic function in the radio?

So glad to hear this worked and the fix was easy! Did you use an online tutorial to guide the removal of old screen and install the new one? A link would be super helpful, if you have one. My 2016 Silverado has this same problem, and I've just come from the dealership, where they quoted me $800 parts and labor to change out the screen. That's on top of the $100 I paid today for diagnostics. 😬 Thinking of tackling it by myself and looking for any helpful hints. Thanks!

Try a search on Youtube. I am sure somebody has posted a video on changing out the screen.

Since I too suffer this problem, I'm going to remove the brown ribbon cable (seen in the second vid) from the PC board and confirm that the screen works sans the touch component. Run it like that for awhile before replacing the actual screen itself.

Time will tell.

Into the second week of the digitizer cable "unplug" and everything is back to normal. Kudos to Col GMC for the idea. As stated, most all controls work the screen though I continue to wade through the menus. Still, I'm in for the long haul in seeing how this works before (if ever) replacing the digitizer screen itself.

I finally got around to replacing the digitizer.

No more jumpy screen.

I had already purchased the new digitizer before I saw this post so once I removed it I just replaced it.

It took me about 30-45 minutes thanks to all the support/video links etc...on this site.

I appreciate it.

If you replaced just the digitizer/glass, its probably one of the ribbon cables you had to remove to do the work.  Un clip them again, blow any dust off them and make sure they are completely seated before pushing the clip back down to secure.  (Aka your screen can't be black/off because of the new digitizer, it's just a dumb piece of glass that figures out where your finger touched it.

I’ve been having problems with my touchscreen for the last few months. Almost seems like, as mentioned above, something is pressing against the screen along the left side because it almost always switches to the middle icon on the CarPlay screen. 
 

Now, the last week or two, I’ve started to notice the small display behind the steering wheel is acting up, switching to the audio info on its own. It doesn’t change anything on the radio, but the speedo display shifts to audio with no input from me. None of my buttons on the wheel appear to be stuck. 
 

Any ideas on a fix, or if they are related or not?

      Winter Returned

      .30” of rain all month and it’s been weeks since that. “Mowed” our two properties today for the first time since July 2nd. It only took 30 minutes because all I had to do was level some weeds and saplings in a few problem areas. Everything else is dead.

      Shift to Park Message Warranty Claim

      By tjonesdfw · Posted

      Dealer reported a failed shifter module assembly so the whole shifter is getting replaced. Yet another premature repair… up to $12,000+ in extended warranty payout in only 5 years and 80,000 miles!

      2021 with Intermittent AC Cooling Issues

      By tjonesdfw · Posted

      According to the dealer it’s an internal leak/failure of the compressor.  Again, another failure that shouldn’t happen at only 5 years and 80k miles.  For some reason the compressors must be hard to come by right now, because the truck’s been at the dealer almost a week and they just located a compressor at another dealer several states away today.  We’ll see if this fixes the issue.

      Brake Bleed Procedure

      By needafix · Posted

      I'm not sure if this should be a reply on this thread or a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - ACDelco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles. When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so i did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance.

      I wasn’t commenting on your post. Certainly wasn’t arguing. I was making an observation on my long term experience with supposedly proper length of driving for proper heat cycles. Works for me. Although I have seen water or vapor come out of exhaust when vehicles weren’t run very long and shut off. It’s very humid in the morning. Then hot and humid.
