Camaro and Firebird: Why Aren't My Brake Lights/Turn Signals Working?

Instead of worrying about whether or not your non-working brake lights are going to cause problems, fix them. Here are a few common problems that can cause your brake lights to malfunction.

This article applies to the Chevrolet Camaro (1990-2015).

Not only do damaged taillights increase the chance of an accident, they can lead to larger wiring problems for your car. Often, problems begin with an issue due to a short in the system, which can lead to blown bulbs or fuses. At the worst, these harnesses can even burn causing a chance of fire. Fortunately, the harnesses, sockets, and bulbs are all very easy to manage and repair. Check out these three common problems that cause your rear tail and brake lights to stop working.

Materials Needed

  • Test light
  • Flash light
  • Replacement bulbs
  • Replacement fuses

Step 1 – Check the fuses

A fuse might be blown.

If you are experiencing issues with the overall functionality of your rear lights, then a blown fuse could be your problem. To check for a damaged fuse do the following:

  • Locate the fuse cabin fuse panel.
  • Grab your test light and check the brake light fuse.
  • If it is good, then move on to the next step. If it's blown, replace it.

Step 2 – Check the bulbs

They could be burnt out.

Bulb replacements are often overlooked. However, even if there was a blown fuse present, the short may have also blown the bulb. The rear bulbs themselves are different from other cars' bulbs and have two filaments: one is bright and the other is dim. The bright filament is used for the brake lights, while the dim filament is used for running/taillights. The brights can fail without the issue of the other dim filaments being affected. However, if both filaments are affected, then the turn signals will not work properly.

  • Turn the hazards on.
  • If they are working properly, replace the brake lights.

Step 3 –Check the taillight sockets

The sockets may have a short.

1990-2002 Camaros are notorious for having sealing issues on their taillights. This can cause water to seep in and damage the sockets. The damaged sockets can then cause a short in the system, resulting in blown fuses and lights.

  • Remove the taillight covers.
  • Remove each bulb.
  • Inspect the socket for wear.
  • If damaged, cut off and replace the socket.

Many people take this opportunity to retrofit taillights from different styles such as the LS model. This will take care of a lot of issues the older models face.
