Long story short, my 2015 Tahoe will randomly beep as if someone is pressing the center console screen, but nothing on the screen usually changes, although the small screen on the instrument cluster will change from the speedometer to the bluetooth page, and never a different page... dealer claimed it was a faulty digitizer and wanted $1,500 + 5hrs labor.
I've replaced the digitizer no problem, but the problem persists. My only remaining guesses are the HMI or the Control Panel?
For what its worth, all buttons on the steering wheel and on the center console work fine.
1) Is there a way to troubleshoot HMI vs Control Panel? I'd like to avoid replacing both if possible.
2) if it's the HMI I'm assuming I will have to get it programmed to my vin... any ideas how to do that?
All input is appreciated
