2017 GMC Sierra K2XX Fuse Box Diagram

This block is mounted on the driver's side of the engine bay next to the battery. Press the catches on the long side of the cover and lift it clear; the fuse layout is printed on the inside of the cover.

MY2017 keeps the numbering introduced in the November 2015 handbook and adds three positions to the same tray: the electric running board fuse 74 sits at the top left beside cartridge 3, the fuel pump prime relay 75 is on the right of the middle band, and its fuse 76 is the small horizontal socket in the bottom right corner above 54. Cartridges run across the top, blades through the middle, relays across the bottom.

Open the driver's door and take the trim cover off the end of the dashboard; the block faces you, printed side up, with the fuse puller clipped into it.

From MY2017 the plate is drawn in relief but places every socket exactly where the earlier trucks put it: the single fuse 1 and the pairs 2/3 and 6-9 along the top, the two 50 A cartridges and the relays 49 and 50 down the left, the tall three-pin fuses 22 to 26 across the centre, 29 to 34 under them, and 37, 38, 40, 41 and 43 to 45 in the bottom band.

Open the passenger door and pull the cover off the end of the dashboard; the block is behind it, angled so the printed side faces the door opening.

The MY2017 drawing shows the housing in relief but keeps every socket where it has always been: outlets 1 and 2 at the top left, body control module fuses 7, 8 and the rear seat entertainment and cargo lamp fuses 9 and 10 along the top, the radio fuse 18 and sunroof fuse 20 on the right, and the blower, window and seat fuses across the bottom.
