You probably pulled the wiring plug off the back of the socket. Or the fuse went when the socket came out.

The lighter socket or the element.
Check the element for burn marks and the socket for debris blocking the contacts.

be sure to check underhood fuse block fuses as well as IPC fuse block,LH side. there is a common fuse for both of the power port/lighter asm.

After you read this, tell everyone you know, not to disconnect the battery on late model vehicles, without first inserting a low voltage device into the cigarette lighter socket. Otherwise they will accomplish what you did. Killed the car!!!

What you inadvertantly did was arm the anti-theft system. I dont like being the bearer of bad news, so call your favorite GM dealer and they will tell you all about what it will take to bring your truck back to life.

sometimes they separate those because one is a higher amp circuit (power outlet) versus a cigarette lighter, so check your fuses

check for power to the brake assembly. the socket board in high mounts are prone to have problems. if you have power to the socket board then it needs replaced.

FUSE UNDER HOOD FOR CIGARETTE LIGHTER IS BLOWN

If there is no power to the sockets, changing the bulb wont correct the problem. Check all fuses. Check for current to the tailight. Check for ground to the tailight. Repair as nesessary.
Check cigarette lighter filament. It may be faulty. Check inside cigarette lighter socket. It may have a foreign material in it causing the short.

your fuse panel is either under the dash by the drivers left knee or on the side of the dash where it meets the door. the radio fuse should be the second from the top right side of the fuse panel. its a 10 amp fuse. the power for the switch should be a 16 gauge wire run from the passenger firewall (under hood.) behind a plastic cover where a lot of wires are bolted to posts. that red wire feeds power to almost everything in the cab. it runs behind the glove box and has a disconnect there. if the fuse is not bad and the wire looks good, check the ground on the passenger door "open switch" (the one that is supposed to turn on the dome light. that is where the whole system is grounded for the int. lights lights
