Cigarette Lighters not working

I have a 2005 Nissan Xterra, 68,000 miles. There are 2 cigarrette lighter/power sockets on the front dash console. The top one works but the bottom one doesn't. There is also a similar power socket inside of the arm rest box. That one works. Lastly, there is a power socket on in the rear of the car in the cargo area. That one does not work.

I tested all the fuses in the fuse box inside the cabin by the glove box and all of the fuses were good. There are also fuses under the engine compartment, but I havent tested those yet.

Is this a fuse problem or some other electrical problem? Thanks for any advice.
