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.

I just replaced the digitizer lcd monator on my 2015 gmc sierra with one I bought off Amazon, sold by Dngbymx auto parts, and my screen is black, radio works, but you have to change stations thru steering wheel, anyone experanced this ?

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?

      Would this be normal or a worn CV Shaft? 51K miles 3.5" lift? Boots are intact and no visible leaks showing. Attached is a the video I took. Thanks     https://youtu.be/ZnW7PPRmjJY?feature=shared

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin.
