Where can I get the socket, tail light assembly off side, that the tail light cluster assembly plugs into, there is a burnt connection in the socket I have fitted a new tail light assembly to??

first off ,you did electric work and skipped step 1
pull battery neg lug first.
so you blew the fuses.
what IP lights. all warning lamps.
or just the park lamps in the cluster.
part is called Illumination in said cluster.

where is these other lights, what is a driving light, (park, head,turn, what? brakes?)
tell all lights that work & not , inside and outside car.
tell what knob you turn. can be like 10x better clue...?????
burned sockets are shorted lamps, the brass base lamps love to short inside, (china made x10) get new ones from top maker....

ok, so after replacing the TL assy.
what dont work now, report all lamps.
if it's only outside lamps failing, say so..
i guess you dont know that parking lamps go to like 20+ places, inside and outside car. so. parking lamps are special if acting up
then brake lamps
then blinkers (turn signals)
then reverse.

if the parks (aka, incorrectly TAIL) are bad, then we need to know that. using the correct word.
parks are on all 4 counters, and side lights and inside car.
that is why tail lamp , is a bad name. but fuses are marked as tail on many cars.

also when working on car external lighting
make sure no trailer towing hacks are found.
look for non OEM hack jobs, at the rear corners. Uhual hacks.
or past collision damage to wiring not repaired properly.

how is that>?

The tail light circuit is separate from the brake and turn signal circuit. Either the bulb socket has gone bad or a wire has flaked out. Check for voltage at the socket on either pin base when you have your parking lights on. If voltage is present, it is either a worn socket failing to hold the bulb properly, or another bad bulb. If no voltage, determine which wire on the other side is tail light power, and run a new wire across to the side that isn't working and connect it to provide power.

Check for power with a test light(not a dvom) at the tail lamp assembly. Test right at the spot where the bulb socket sits. If you have power then i would check the connection tab on the bulb socket itself for pits or corroded tabs. If you do not have power present at test point then double check the fuse chart and see if it says 'electronic' instead of having a fuse amp rating for the tail lamps. If it says electronic for any of the light circuits then it means their is no external fuse that can be replaced and the problem is most likely internal of the headlight switch. Since the headlight switch is actually a power source for the lights. I would start there at this point. Let me know what you find and if you need anything else just let me know

You want to change the tail light bulb?

The process for replacing tail light bulbs is the same in all models. If you have a burnt-out tail light bulb, you may need to replace the brake light, the reverse light or the turn signal. The procedure to replace each of the bulbs is the same.

Instructions

1. Open the Hummer's rear swing gate. This will expose the edge of the vehicle's tail light assembly. You'll see two small Phillips head screws that hold the tail light assembly in place. Put on your gloves.


2. Remove the two screws from the tail light assembly. Pull the tail light out and inspect the back for two bulbs. The top bulb is the brake light and turn signal. The bottom bulb is the reverse bulb. Determine which bulb you need to replace.

3Rotate the bulb's socket counterclockwise to disconnect it. Unplug the bulb from its socket.

4Push the replacement bulb into its socket firmly. Insert the socket back into the tail light. Turn it clockwise to secure it in place.

5Place the tail light into its cradle. Hold it with one hand and replace the Phillips head screws with the other.

Tail Lamp Assembly Removal & Installation To Remove:

1. Open the rear compartment.
2. If equipped, disconnect the cargo net.
3. Remove the wingnut and pull back the rear compartment trim panel.
4. Remove the wingnuts from the tail lamp assembly.
5. Remove the tail lamp assembly from the rear body panel.
6. Disconnect the electrical connector from the tail lamp assembly.
7. Remove the tail lamp socket by turning counterclockwise.
8. Remove the side marker lamp socket by turning counterclockwise.

To Install:

1. Install the side marker lamp socket by turning clockwise.
2. Install the tail lamp socket by turning clockwise.
3. Connect the electrical connector to the tail lamp assembly.
4. Position the tail lamp assembly to the rear body panel.
5. Install and secure the wingnuts that attach the tail lamp assembly to the body panel.
6. Position the rear trim panel to the rear compartment. Install and secure the wingnut.
7. If equipped, connect the cargo net.
8. Close the rear compartment.

Try replacing the passenger side tail light bulb.
Inside trunk, remove two black plastic nuts holding carpet liner in place on side where bulb is burnt out.
Pull back carpet, use a flat screwdriver to pop out the wiring. Remove three nuts using a small open-ended socket or pliers.
Pop out entire tail light assembly. Locate bulb to be replaced. Rotate 1/4 turn to remove from socket. Replace bulb and repeat in reverse order to reinstall.
Thank you for using fixya and good luck

remove the bulb thats out, check the socket it's in for burnt contacts as this is common. if the contacts are burnt check the metal contacts on the tail light assembly, if they are burnt you will have to replace the whole assembly. if they are ok replace the bulb and socket

The entire tail light assembly pulls out from the fender well. You can access the socket for the tail light on the inside of the trunk, but in order to change the bulbs you will need to pull the tail light assembly out from the socket. Check inside to see if there are any retaining straps, otherwise use your fingers to get under the outer edge of the tail light assembly and gentlu pull it out. Don't pull too far because the wires will still be connected between the tail light assembly and the socket. The bulbs are then easily accessible and can be changed. Reverse the procedure to re-install.

Most of these type lights do not have a plug. I am assuming that you want to replace a burnt out lamp.

Here's what you do. Remove the assembtail lamp assembly. It is usually held on with 2 or 3 phillips head screws. If the problem is a burnt out lamp, the lamp assembly will unscrew from the unit by turning it counterclockwise about a quarter turn. Take the bad bulb to an auto parts store and get a replacement. The bulb will only fit one way into its socket. Then take the socket with the new bulb and insert it back in the housing. Again it will only fit one way. remount the tail light assembly.

If the actual plastic tail light assembly is broken or cracked remove the lamp assembly as described above, take the broken tail light to a dealer and ghet a new one. They are expensive. I just replaced one for my 95 F-150 pickup and it was $40.

Check the relays associated with the tail lights, I believe that the tail light relay and the turn signal relay are two different entities. Hopefully that helps.
