2016 gmc sierra cigarette lighter fuse (2014 - 2018) - box diagram GMC SIERRA CIGARRETE LIGHTER FUSE
Description
Cigar lighter (power outlet) fuses in the GMC Sierra are the fuses #1, #10, #11 and #12 in the Left Instrument panel fuse box, and fuses #1 and #2 in the Right Instrument panel fuse box

Before you start pulling off interior panels to get to the socket, though, ask yourself how confident you are in your skills
It's a good idea to check your car's manual for specifics, though, since the fuse size can vary by car make and model

If you only have a larger vacuum, cut a toilet paper tube lengthwise so you can form it into a cone shapeone end wide enough to fit over the vacuums tube, the other end narrow enough to fit deep into the socket

Line up the new fuses 2 prongs (the roots in the tooth analogy) over the holes in the correct fuse slot
