Went to start the truck today and when I turn the key I get nothing. Dash and radio don't light up. Checked all the fuses and relays that I thought might be applicable, but everything looks fine. Battery has a full charge, Interior lights work, but the passenger side headlight doesn't come on and the driver's side turn signal doesn't blink when locking and unlocking the truck. Anyone heard of this issue before? I have a 2016 Sierra 1500 5.3L Z71 with 10,000 miles. Haven't had any issues until now.
