Chevrolet Trailblazer Tail Light Assembly

Common Problems with Chevrolet Trailblazer Tail Light Assembly

In America, rear-end collisions are the most common car-related accidents. One way to prevent them is having functional tail lights all the time. Plus, driving with busted tail lights can get you pulled over by the traffic police and issued a ticket. But even though it is built to last a long time, the Chevrolet Trailblazer tail light assembly can develop a number of problems that will cause it to malfunction or not function at all. Here are the most common problems you may encounter with your tail lights. It is important to know how to identify them so that you can be able to provide the exact solutions with efficiency.

Blown bulbs

When one bulb is not lighting up, it is most likely blown. Open the hatch and take the tail light assembly out. Disconnect the electrical plug that runs to the tail light to pull the electrical connection apart. Take the bulb off of the assembly and inspect its filament to see if it is broken. If it is, you will need to replace the bulb with a new one.

Damaged wires

If the trouble is not a blown bulb, check the wires running to the tail light housing next. There may be a short or some frays on the wire. If you confirm damages on the wires, have it checked and serviced by a professional mechanic to avoid other problems.

Blown fuse

When there are multiple bulbs that do not work at the same time, a blown fuse is most likely the cause of the problem. Pop up the hood and check to see if the tail lights fuse is blown. Inspect it, and if you see a thin metal strip inside that is broken, then the fuse is definitely blown.


Take a close look at your Chevrolet Trailblazer tail light assembly and check to see if there is any moisture inside. The water droplets that line the inner walls of the tail light assembly lessen the amount of perceivable light, which can cause a rear-end collision. This problem is usually caused by having worn out or brittle seals around the bulbs. Also, if you live in an area where rain comes frequently, this can become an utterly annoying problem.

  • Simple Tips to Keep Chevrolet Trailblazer Tail Light Assembly in Excellent Condition

    Your Chevrolet Trailblazer tail light assembly may not be a main engine component that takes you to places, but it is a vital part that keeps you visible from the rear especially when you are braving heavy rains and thick fog. To keep your tail light assemblies working, just do the following simple measures.

    Remove condensation.

    If your tail light has water enough for your pet fish to swim in, you have quite a bit of a problem. Take off the tail light assembly from your Trailblazer and drain as much water as you can. Then use a hair dryer to dry up all the droplets and eliminate the water vapor that may still linger inside the housing. Put the dryer to maximum and hold it directly towards the moisture until they disappear. Then leave it outside for 20 minutes. If you return to it and see some more moisture, repeat the process of drying it up using the hair dryer.

    Seal the openings.

    To prevent condensation from forming inside your tail light housing, replace the rubber seals that have become brittle and cracked from all the high temperature. For this, you can use the plumber's tape or Teflon tape to wrap the outer ring of the headlight bulb sockets. Make sure you wrap it enough so that it will not allow any more moisture inside the housing.

    Remove corrosion.

    If there is rust and corrosion present in the bulb socket, it is important that you get rid of them to ensure proper light output. Use a car battery terminal brush and put the pointed end inside the socket and twist it. This will remove the rust and other foreign debris from the socket.

    Restore from scratches.

    Since the tail lights are exposed to various elements of nature, they can get scratched, scuffed, and hazed. To remove these unsightly marks, spray the tail light lenses with an automotive soap-and-water solution. For about 20 seconds, rub the surface from side to side with 1500-grit sandpaper that has been soaked in the solution 20 minutes earlier. Then clean it thoroughly with the soapy solution, and dry it with a clean microfiber cloth afterwards. Apply some liquid automotive paint polish, the use the applicator pad to rub it in a circular motion. Once done, rub off the residue using another microfiber cloth.
