The aux power outlets in my 2007 denali xl dont have power

wrong fuse , the service manual covers all that.
aux = old cig cigar jack in cab ? <<<< names change in time
but is the same CIG port, for sure.
the manual calls it

Horn/Cigar Lighter/Power Outlet oh, so horn is dead too,, sure.
fuse 15 is front CIG
read outlet (omg 2) is fuse 6 , 50amps that feeds FUSE B
fuse B is 20 amps and feds aux rear center pin power.out.

fuse B box name is RELAY and fUSE BOX RFB.

under the hood I would check the thermostat to make sure it open so that the hot antifreeze reaches the sensor to make the fan start

its underneath the hood right above the battery compartment.

check under the hood in the relay/fuse box

The fuse for the cig lighter/power outlet in the console which is the one I am guessing you are talking about is located in the fuse panel under the hood of the vehicle in the engine comaprtment on the drivers side near the battery. There are serveral power outlet fuses so I hope the one in the console is the one you are talking about. Below is a picture of how the fuses are layed out. The one marked "AUX PWR" is the one for the power outlet. This should be in your owners manual if you have one. If you don't and would like a copy, you can email me at [email protected] with your make, model and year and I will be happy to email you a copy of it. No worries, no cost to you. I hope this helps and good luck.

Same problem on my 01', what fuse is it?? I can't find any blown fuses in the hood block or the one under the seat.

YOU MIGHT WANT TO TRY TESTING THE TRAILER PLUG FUSE SOME OF THE THIRD BRAKE LIGHTS WORK OFF THAT FUNCTION. IF THAT DOES WORK TEST THE PLUG FOR POWER BEFORE THE PLUG, IF YOU HAVE POWER THAN IT IS IN THE PLUG, IF YOU DONT THAN CHANCES ARE IT IS IN THE FUSE BOX TEST ALL FUSES UNDER DASH AND UNDER THE HOOD.

Hi there;
The fuse you are most likely looking for is in the Instament panel fuse block located in front of your left knee. It is a 20 amp fuse & is simply labled AUX. AUX 2 is for the rear outlet.
There is a fuse block under the hood, the fuse you are looking for is a 20 amp fuse & it is in possition #53 that is for the upper outlet in the front.
hope this helps
Farrout!

check the fuse that is located inside the charger itself, not under the hood.. remove it and check, once you have replaced the fuse, try charging something else, if it still does not work then you have a bad charger and need it replaced

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.
