My 120v outlet and the lighter outlet on my front dash are not working...where is the fuse located so I can check to see if it's blown?

double posted, why do that?

There is a fuse block located on the drivers side of the dash. If you open the drivers front door there will be a panel on the end of the dash. Remove the panel and there will be a fuse labeled cigar/dlc

I don't have a solution for this problem(yet) but have the exact same issue with a 2005 Silverado. All fuses are good and the cigarette lighter outlet works fine. I am looking to get my hands on a copy of the wiring diagram for this truck. I suspect that there is an inline fuse somewhere in the system that has blown but haven't been able to locate. If anyone has a copy of the service(or Haynes) manual for this truck, I would appreciate a copy of the wiring diagram that shows the accessory outlet.

You mean there seems to be no power to the vehicle's lighter unit outlet.

This lighter unit outlet is normally wired through its own fuse so check the fuse panel in the car for a blown fuse. If blown it must be replaced with a fuse of the correct amperage. The owner's manual will show you where the fuse is located.

Before you check the fuse just check the cigarette lighter outlet with another plug-in device if you have one such as a portable 12 volt tire compressor or a 12 volt plug-in auxiliary light. It could be that if you are using a charger from the outlet, the charger plug or wiring may be faulty rather than the car's power outlet itself. (These outlets don't usually give trouble unless the wiring has been messed with or the outlet itself has been damaged or abused).

If no device works from the lighter power outlet check the fuse as it may be blown.

check all power outlets for loose change or metal objects in the doubble check the rears. fuse should be located on drivers side fuse pannal on side of dash

I am not sure about "fusible link", But the suggeation I can give you is to open dash or where the outlet is located and check the wires in the back of outlet with a light tester.

Yes that would be fuse no 7 which is a 20 amp fuse in the fuse panel under the dash

if from the outlet had power before and you used a test light to test for power . remove the barrel ( the front part of the lighter) in the dash using your thumb to turn it.On some vehicles they have an inline fuse not to far from the cig. lighter on the inside of the dash

According to the Haynes repair manual: "There is no fuse and relay box inside the passenger compartment.  However, there are a number of fuses, relays and circuit breakers in various locations under the dash.  The heated mirror circuits and the circuit for the lower instrument panel power outlet (in the floor console) are fused with self-resetting fuses that are only serviceable by an authorized dealer."  However, in the fusebox under the hood (a.k.a Integrated Power Module) there is a fuse RDO/IP IGN which is the fuse for the radio.  Check this fuse.  Both the radio and the Cigar Lighter are fused through the IPM.

fuse should be located the end of the dash drivers side
