https://share.icloud.com/photos/07fPc8Q-zYTTNT4psmCkhHteA i have a 2018 Sierra and the radio screen randomly started glitching and blacking out, however I can still touch things, the audio works, i can make phone calls and navigation works. I already pulled the fuse and replaced it and reconnected the gm interlink connections under the glove box. Also it doesn’t do it on the mornings when I go to work but on the way back it does. I attached a link for a video of it. Any suggestions? -
Let me start with the beginning of when this all began, 3 nights ago I removed a power wire circuit breaker that was in-line to my sub amp, I connected the sub power terminal directly to my battery (dangerous move I know) 2 nights ago I removed and re-twirled my remote power wire and re-inserted it into the amp Yesterday when leaving work I finally heard my sub kick on for the first time in a month, this morning I tried to crank my truck and it would make a subtle click and nothing else, no power to my instrument panel, radio no nothing. I replaced the battery today and had no luck after, and there wasnt even a "click" after trying to start the truck. So I removed and re-inserted some fuses on all 3 fuse blocks on the truck and when trying to crank, I can hear the entire dash for the most part gets power except radio, and instrument panel. We ran a voltage tester for all fuses except the larger silver ones, so we swapped the silver ones around to see if it helped and had no luck. I will list the accessories that do not work vs which ones do. Accessories that DONT work Horn Radio or Instrument Panel Dash Lights Starter Power Windows Accessories that DO work Overhead lights Keys lock and unlock truck I'm thinking its some sort of accessory power wire short or something but I wanted to get 2nd opinions.
