2016 GMC Sierra K2XX Fuse Box Diagram

Open the hood and look ahead of the driver's-side strut tower: the fuse block is the box beside the battery with a clip-on lid. Its fuse map is moulded into the underside of that lid.

MY2016 renumbers everything above position 53. The aero shutter socket of the 2014 and 2015 trucks is gone, so the accessory power module takes 53, the front washer moves from 55 to 54 and the headlamp fuse from 59 to 58; the fuel pump relay becomes 59 and the relay block ends at 71, with the two circuit links CKT 95 and CKT 92 - marked 72 and 73 - in the top right corner of the tray.

This block sits inside the driver's end of the instrument panel, behind a cover that comes away when you pull it towards you with the driver's door open.

MY2016 adds one socket to the plate: 38, the four-wheel-drive transfer case control module feed, which sits beside 37 above the door fuses 40 and 41. The rest is unchanged - accessory outlets on the 50 A cartridges 10 and 11, the relay 49 around the cigarette lighter fuse 12, the ignition fuses 22 and 23 in the tall middle row, and the heated seat fuses 43 to 45 in the bottom right corner.

This is the smaller of the two dashboard blocks and sits at the passenger end of the instrument panel, behind a cover that pulls straight off.

Nothing moved for MY2016. The two accessory outlets 1 and 2 occupy the top left corner, the relays 50, 51 and 52 fill the left-hand edge, and the fuses run in short rows across the right-hand three quarters of the plate, ending with the 40 A front blower cartridge 43 and the passenger seat fuse 47 along the bottom.
