Hello,
I came back from a month's vacation and my 2017 Silverado is experiencing the same issues. No power to dashboard, no crank....one headlight turns on, fob locks and unlocks vehicle, turning signals work. I replaced the battery...nothing. All fuses are good in cabin and under hood. I did notice one of the terminals on large fuse sitting on battery is not getting any voltage to it. However, I hard wired across it and still nothing happened.
Any advice would greatly be appreciated.
