Remove taillight assembly

I have a 2000 premier model, which I believe is relatively the twin to your 2001, tail light housing and assembly.

First, open your rear hatch door. The taillight housing assemblies are attached with 2 chassis screws. The screw heads are Torx type and the size is somewhere between a T-5, T-10, T-15 OR T-20. Most standard sets of Torx drivers include these sizes, and if your not familiar with Torx tools, they are the relatively newer type of screw driver head that look like a star when you look at the top of the screw head or the tip end of the driver. Common in automotive parts attachment, currently, so any auto parts store will stock these tools. A set can be purchased for around 5-20 bucks.

Once you locate the 2 attachment screws on your taillight assembly, remove the bottom screw first. Be careful not to lose the screws.

When you remove the top screw, the light housing will pull out about an inch to clear the 2 back side pegs on the assembly, (that slide out of/into the two holes in the car body socket), which align the assembly into perfect position when it is installed in it\'s proper position/ place. Once these pegs are clear of their alignment holes the assembly will be free to turn and see/access the bulb sockets that are attached to the back side of the taillight assembly. I like to use a stool, (that is the same height as the lower part of the assembly when it is in place on the car), to rest the assembly on after I remove it. I prefer to do this because otherwise all the weight of the light assembly will be supported by the wires, (that extend out of the car body when the assembly is pulled away/off of the vehicle), when you need both hands to do something and have to release your hold on the assembly. And when you do release the assembly, those weight supporting wires will come to rest against the fairly sharp edged metal perforations in the car body, which could easily cause damage to the wires or electronics.

Once the awkwardly shaped assembly is out you will see there are 3 bulb sockets attached to the rear side of the assembly. These sockets are removed by depressing the plastic lock tabs on the sides of the bulb socket. These lock tabs are located against the point of connection to the taillight assembly. Once the lock tabs are depressed, carefully spin the bulb socket counter clockwise about a quarter turn and gently pull the socket away from the assembly.

The bulbs will come out by pressing down toward the bulb socket, (you will feel a spring depress and expand if you push in then release). With the bulb fully depressed into the socket, spin it counter clock wise slightly, then release the bulb depression and pull it out of it\'s socket. Careful to replace the sockets in the original order if you remove more than one at a time.

Reverse these instructions to replace the taillight assembly, but be extra careful not to over tighten the screws on re-assembly. The plastic assemblies become brittle with age. Usually once the screws are both evenly lightly snug against the assembly, another half turn is sufficient to hold them securely in place. The back hatch door prevents them from ever falling out, but just grab and wiggle the assembly the next few times you open and close the back hatch. If any movement occurs.....retighten, using the same technique as prescribed above. Do not over tighten. A new/used light assembly could set you back 50-100 dollars each.

If you have a bulb that seems to work sometimes and not other, use a pencil eraser to clean the point of connection in the bulb socket, (inner bottom of the socket with the bulb removed), (two brass tits), and the bottom of a reused bulb, (also two brass tits),before re-installing the bulb in it\'s socket.

Also, I believe there is a metallic connection that is made when the bulb socket is re-connected to the taillight assembly. Use the pencil eraser to rub off any tarnish on both connection surfaces before re-installing.

Aligning the ears on the bulb socket back into the matching openings on the light assembly, then a quarter turn clock wise, (or until you see or hear the lock tabs spring back into the locked position), to reattach the bulbs back into the assembly housing.

I do believe this is the reason, (tarnish on one or two or three of the above mentioned metallic connections), I have had my taillight assembly apart on two occasions, other than times I was replacing a dead bulb. And I think I saw mention of the same problem by a few other silhouette owners when reviewing repair forums, so it could be a common problem on olds Silhouette vans around our model year.

Recalling the process again in my mind leads me to suspect that maybe a third electrical connection/circuit is made between the assembly body and the car body when it\'s in it\'s place on the car. Just examine the surfaces where the two will touch each other when in place to possibly find somewhere where there is/might be a metal on metal common spot. If so....rub both surfaces with the eraser before re-assembly on to the car.

If you have a dead bulb, be careful to buy the exact bulb attachment configuration, (the two tits at the bottom are either an even distance from the bulb bottom or offset with the distance from the bottom differing), and one of the trio/duo of light bulbs in each of the taillight assembly may be tinted amber instead of clear like the other(s) in the assembly. But you won\'t be able to easily notice the colored bulb until it\'s removed from the assembly due to the assembly lens being contoured or colored itself too. I think.

Bulbs normally come in a pack of two and cost around 3-5 bucks a pair. It isn\'t necessarily important to replace both the right and left bulbs when you only have one out....Bulb life varies greatly from bulb to bulb and may be affected more by vibrations and bumps than age. Just store the extra bulb and the Torx driver in your glove box for when the next bulb that size burns out.

You have two fuse boxes and each have a fuse for the lights in the tail assembly. The one under the front hood will have a blinker relay in it too. The one in the side dash on the passenger side may have a couple of fuses that protect the back up lights and the tail/brake or running lights. The cover and the lid for the fuse boxes have fuse/relay location diagrams on their under sides and identification labeling for all the fuses, or the owners manual also has the same information in it, near the end pages of the manual.

If you disconnect the battery, you may have to reset your alarm system, (which isn\'t easy in some models), cause injury or really damage electronics. Best to avoid disconnecting the battery for any time longer than a few minutes if at all possible. And when working with the taillight assemblies, it is relatively safe from cross connections, especially if you use a stool or something to rest the assembly on while it\'s out of the car body and don\'t use anything metallic to clean the connection prescribed above. It\'s very simple to do and harmless to you and your vehicle if done right.

Oh, and the last thing....if your experiencing brake light problems, there is a switch down on the brake pedal arm that is visible with a flashlight you can check and make sure you have a helper to depress the brake pedal for you when/if you have to test the brake lights for any reason.

Good luck and be safe every time you work on your car.

How do i change out my rear brake light bulb

Instructions on how to change the bulbs should be inside your owners manual.But here you go;

Lift the tailgate and ensure that it is properly supported.
  • 3 Remove the two screws at the top of the taillight assembly with a Phillips screwdriver. Set both screws together, to the side of your work area.
  • 4 Grasp the taillight assembly horizontally on the left and right. Slowly pull the assembly toward you and away from the truck's frame. Use care while you're pulling the taillight assembly as there will still be wiring connected to it. Once the assembly is away from the frame lay it down on the bumper.
  • 5 Remove the brake light socket from the taillight assembly. Rotate the socket a quarter-turn counter-clockwise to unlock it from the assembly. Withdraw the socket slowly from the hole on the taillight assembly to avoid breaking the brake light bulb.
  • 6 Remove the brake light bulb from its socket by grasping it between three fingers and pulling it straight out of the socket. Put on some latex gloves before you touch the new brake light bulb.
  • 7 Place a small hairline bead of dielectric grease on the metal contacts at the base, on both sides of the brake light bulb. If the grease gets anywhere on the glass portion of the bulb, discard it and start with a fresh bulb. This grease is not absolutely necessary.
  • 8 Insert the brake light bulb back into its socket. Push down on the bulb gently until it seats itself.
  • 9 Now that it's connected carefully insert the bulb into the socket back through the hole on the taillight assembly. Lock the socket back in place by rotating it a quarter-turn clockwise. Do not over rotate the socket. When it locks in place, you stop rotating.
  • 10 Lift the taillight assembly up off the bumper. Position it so that it's ready for re-installation. Push the assembly back into place on the frame. Make sure that all of its wires are tucked back behind it and that no wires get pinched.
  • 11 Reinstall the two mounting screws and tighten them a quarterturn past hand tight. Shut the lift gate door.

    Left brake light dont work when brake peddel is applied

    Replace the bulb,
    1. Open the lift gate on the rear of your Blazer or drop it if you have the tail gate that folds down. Locate the screws on the inner edge of the lift gate frame. There are two screws--remove them with a Phillips screwdriver.
    2. Slide the taillight assembly out of the rear of the truck, being careful to not break the locating tabs on the rear of the housing. Locate the bulb sockets on the rear of the taillight assembly.
    3. Rotate the light bulb socket counterclockwise about a quarter turn to unlock it from the taillight assembly. Pull the socket straight out of the assembly with the bulb attached to it.
    4. Remove the bulb from the socket by pulling it straight out of the socket. If you are removing the entire assembly from the truck, remove the remaining sockets from the rear of the taillight assembly, lay them aside and remove the assembly completely.
    5. Reinstall everything in revers and don't for get to *** some grease to your socket before you place the new bulb in place and test the operation of the new bulb before you reinstall the tail light.
    Thank you for using fixya and here is the bulb you need for the trail light.The 1999 Blazer uses a 3057 bulb available at most auto parts stores.

    How to change a tail light bulb in a honda element

    Open the hatch and the tailgate.

    Remove the two mounting screws with a Phillips-head screwdriver, and remove the taillight assembly from the body by pulling it back.

    Determine which of the three bulbs is burned out: brake/taillight, turn signal light or backup light. (I assume you’ve already determined this)

    Remove the socket by turning it one-quarter turn counterclockwise.

    Pull the bulb straight out of its socket.

    Push the new bulb straight into the socket until it bottoms.

    Reinstall the socket into the light assembly by turning it clockwise until it locks.

    Test the lights to make sure the new bulb is working.

    When reinstalling the taillight assembly, first place the two pins in the holes in place. Tighten the two mounting bolts.

    Hope this is helpful to you.

    I need to replace a taillight bulb.

    You should be able to open the hatch and look on the inside of taillight housing. there should be two or three screws on the inside where the hatch seals. remove these screws and it should pop out. once its out unplug the connectors and you can twist the bulb out remove the bulb from the socket and replace. then just reverse the process.
