Where is the cigarette lighter fuse box in an 03 suburban?

The cigarette lighter fuse for a Chevrolet City Express LT is located in the Engine Compartment Fuse Box. The location of the fuse box varies depending on the year of the vehicle. For instance, in 2003-2007 models, the cigar lighter (power outlet) fuses are numbered 29 (Auxiliary Power Outlets) and 30 (Cigarette Lighter). In 2008-2009 models, they are numbered 33 (Auxiliary Power Outlet) and 38 (Cigarette Lighter). In 2010-2022 models, they are numbered 25 (Auxiliary Power Outlet) and 73 (Cigarette Lighter).

The data link connector uses the same fuse as the cigarette lighter socket. Does that work? Check your fuses.

There should be a fuse block under the hood. Go double-check.

FUSE BOX UNDER THE HOOD DRIVER SIDE.I DONT REMEMBER WHICH ONE ITS BUT JUST CHECK THEM ALL.I HAD THIS PROBLEM ONCE DUE TO A PENNY FALLING IN THE LIGHTER PORT.

Hello padgett1 1
The cigarette lighter shares fuse #8 20amp with the horn and parking lights, in the fuse block behind an access panel on the left side of the dash. Hope this helps.

Woohoo Just Found The Answer. Its in the fuse box located under the headlamp switch labeled "T/G REL" and it's a 25 amp fuse!

In the 2006 Model the Cigarette lighter is located behind the small compartment on the drivers side dashboard left of the steering wheel. Simply lower the compartment door (Fuse box cover) and remove it to access the fuses. Jul 2010

Possibly the wire has come loose. This happens a lot with lighters! Try putting your finger in ( it won't hurt you, and you won't get electrocuted ), and turning the insides in a clock-wise direction . You will feel the whole lighter tighten up. If this doesn't help, turn it in an anti-clockwise direction. This will take the socket out of the car. Check that the two wires on the back of the lighter are firmly connected. Then put the lighter back in, and hopefully it's OK.

Unplug cigarette lighter, check circuit, unplug each door individualy at first, Don't forget the back doors, check circuit. Usualy the door wiring is damaged but there may be more then two cigarette lightes depending on the model.

make sure you check the fuse box under the hood.
i had the same problem with my 03 gagt and thats what it was.
check the owners manual and find out which one it is for sure
