Gmc envoy 12v outlet problems - 1998 GMC Envoy

SOURCE: power outlets dont work

I just purchased a 2002 Envoy and had the same problem. If you raise the drivers's side rear seat, you will see a big black box. Remove this box by pulling the bottom of the box outward and it will come straight up. Next you will see a black cover. This cover has a push tab on each end. Push
the tabs at the same time and lift up on the cover and it can be removed. Inside the cover there is a fuse diagram. The fuse number for my 2002 was #46. This fuse controls the front plugs and #15 controls the back plugs. Locate the the fuse puller on the top left, then count over to spare fuse #3. Between #3 and #4 the fuse is located about 1 1/2 inches below those fuses. You will see a yellow 20 amp pin fuse (BP/ATM-20RP AUTOZONE). remove and check fuse.

Good luck

Check the fuses for the power outlets.They are separate than the cigar outlet.They are located under the back rear seat on the drivers side.It will be fuse number 46 for power outlet 1 and 15 for outlet 2.Hope this helps.Good luck.
