I ended up finding that if I wiggled the wire and blue connector going into the HMI it would work off and on. So I unplugged it, plugged it back in a few times, and for now it seems to work fine. Maybe the truck will make it another 8 years before it happens again.
Hello all,
I have a 2014 silverado that the display screen above the radio is black yet the radio keeps playing. In doing google searches I see it maybe could be a bad hmi, or a bad display screen, or a wiring issue somewhere, or a third or fourth thing I think. I'm hoping with the information I provided someone can point me to something a bit more specific.
Thank you!
