03 silverado cigarette lighter not working. I checked all fuses, pulled console and checked wiring and changed socket. And still nothing any suggestions

Do you get 12v at the socket? What about at the fuse? Replace the fuse with a fresh one just in case. Sometimes they get finnicky as they age.

I got a 12v socket and new fuse. I even got a voltmeter and checked both fuses under the hood and by the driver side door

I got a 12v socket

Were you able to measure 12vdc AT the socket? If you have 12vdc at the fuse and not at the socket, you have a short between the fuse and the socket in the wire harness.

Ok so what will I have to do then?

First confirm that you are getting 12v at the fuse and not at the socket. If you have a short in the wire and it is not blowing the fuse it might just be a break in the wire (not touching a ground). You have to find it and repair the break or just run a new wire feom the fuse to the socket.

did you use the cigarette lighter of the push in , then it does not burn the pot ... a lot of the older lighter flame heater ..

I am actually thinking about putting the old "real" socket in my 08 and ditching the aux port "modern" socket. Wonder if I should go to the scrap yard and get an old one there.

That would be do you have power at your OBD2 port if you don't then it would be the fuse the cigarette lighter coming through I see that yours should be working. If you have power at the OBD port then pull that entire cigarette lighter right out of the console and check the wires I've had mine mouth together before.

1. A short will blow the fuse, voltage one side of the fuse only.
2. No voltage at the cig lighter is a blown fuse or an open.
3. After replacing the fuse because it was blown and no voltage at the cig lighter, a short can burn a wire open.
4. A short would be caused with contract to the chassis (metal) which is ground. Not in a shielded harness unless it was hacked into to power something else. More likely it's the cause for a 20 year old truck if you were not the original owner.

I got a voltmeter to the 10 amp cigarette/power outlet in the fuse box under the hood. And got 0v. Checked the other fuses around and got 12v? Any suggestions?

Some trucks need the key on.

Did you check both sides of the fuse?
A blown fuse will have 12v on one side, 0v on the other.

It was running
