GM Infotainment Console Blues

Published on 11/18/2022, Edited on November 24, 2022 |

TL;DR There's a specific cable bundle to try reseating if the infotainment console on your truck stops working.

I recently installed a dashcam in a 2019 Chevrolet Silverado 1500. The hardwiring went fine, up until the point I tried to tuck and tidy the 3 wire kit behind a panel under the passenger side dash - at which point the screen for the infotainment system lost its display, the podcast I was listening to stopped, and I could no longer get it to respond to any inputs.

I tried "resetting" the console through various button presses. Does this ever work for anyone?. No combo seemed to work. I tried pulling the relevant fuses (INFO1 and INFO2), but neither resolved the issue. The screen continued to flicker between nothing and a blank black panel, occasionally a strange vignetted grey/white vertically split pattern I lovingly refer to as "Frustration Grey." Eventually, while checking through to see if I had yanked any cable bundles loose, I determined that one of two bundles in the picture below was loosely seated in its socket. Pushing on it seemed to resolve the display issue. Tugging on it slightly (without removing it from its seat) caused the screen to black out. I pushed it back into its seat and have had a working infotainment console since!

In summary, here are the things I have learned:

  1. The INFO2 fuse covers the control lights and blower for the dash AC/heater equipment
  2. The INFO1 fuse covers the actual infotainment touchscreen
  3. The wire bundles seen above must be firmly seated under the passenger side fuse box, and may be prone to coming loose, based on other people's seemingly inexplicable issues with their console suddenly not functioning.
