Problem 1: Burnt Out Bulbs

Burnt-out bulbs are the most reported issue by car owners for brake light problems. So, if your Chevy truck brake lights are not working, it can be due to burnt-out bulbs. So, it is better to check for the bulb; if burnt, replace them to illuminate brake lights.

Solution 1:

  1. Turn on your Chevy truck and look for which light is not working.
  2. Once identified, remove its cover by unscrewing it.
  3. Once the cover is removed, look at the bulb for damage.
  4. If it needs replacement, buy a new good quality bulb. I recommend Alla lighting Red LED bulbs. They are affordable, but their performance is outstanding.
  5. Remove the burnt bulb, install the new one, and secure it properly.
  6. Test the bulb; put the brake light’s cover back if it works fine. You have done your job.

Problem 2: Blown Fuse

A blown fuse is one of the common causes for Chevy Silverado models. A faulty fuse cannot continue the power supply to the brake lights. So, it is better to check for the fuse and make sure it’s working; otherwise, replace it.

Do you know blown fuse is a common issue for many vehicle brands? You can also check if you have a Kia brake lights problem or a 2004 jeep grand cherokee lights problem.

Solution 2:

  1. Turn off your Chevy truck and look for the fuse box under the dashboard or in the engine compartment. 
  2. Open the fuse box and locate the brake lights fuse. If you cannot identify it, take help from the owner’s manual.
  3. Once located, check for the fuse. If it is damaged, replace it with a new one. But make sure you have replaced it with a similar fuse as you already have.
  4. Once done, test the brake lights and ensure they work fine.

Problem 3: Bad Relay

Your Chevy brake lights may not work due to a bad relay. Once the relay is faulty, it will disconnect the power supply to the brake lights. So it is a must to ensure the relay is okay; otherwise, your problem will remain to exist.

Notes: Bad Relay Also Can Be The Culprit For The license plate lights problem.

Solution 3:

  1. The Chevy truck relay for brake lights is also located in the fuse box.
  2. Check the relay and make sure it is okay. If the relay has damage, you must replace it with a new one.
  3. Remove the relay with pliers carefully and install the new one.
  4. Once installed, test the relay and ensure proper power continuity.

The brake pedal position sensor is responsible for sending a message to the brake lights to turn one when you press the brake. If it fails, you will experience Silverado brake lights not working. You must replace it to get your brake lights back to work.

  1. Locate the BPPS, which is usually mounted on the brake pedal bracket under the dashboard.
  2. Check the wiring harness and connections for any signs of damage or corrosion. Clean or replace the wiring harness as necessary.
  3. Disconnect the BPPS from the wiring harness and remove it from the bracket.
  4. Test the BPPS using a multimeter to determine if it is functioning correctly. If it is faulty, replace it with a new one. I recommend General Motors GM Genuine BPPS. It works smoothly with all models of Chevy trucks.
  5. Reinstall the new BPPS onto the brake pedal bracket and connect the wiring harness.
  6. Test the brake lights to ensure they’re working correctly.

Problem 5: Defective Brake Light Assembly

If your Chevy truck brake light assembly is defective, you may experience the same brake light issue. You must check for the brake assembly to get rid of the problem.

Solution 5:

  1. Identify the location of the brake light assembly on your Chevy vehicle. Typically, it is located on the rear of the vehicle, and you can access it by opening the trunk or tailgate.
  2. Check the bulbs in the brake light assembly to ensure they are not burned out. If the bulbs are the problem, replace them with new ones. You can replace the bulbs with KISLED 12-24V Extremely Bright LED Bulbs. You will find them an excellent replacement.
  3. If the bulbs are okay, check the wiring connections to the brake light assembly to ensure they are secure and not corroded if you find any loose or corroded connections, clean and tighten them.
  4. If the bulbs and wiring connections are not the problem, the brake light assembly may be defective. You may find it repaired, but it is better to replace the assembly.
  5. To replace the brake light assembly, remove the old assembly by disconnecting any wiring connections and removing any screws or clips holding it in place.
  6. Install the new brake light assembly by reconnecting the wiring connections and securing it with screws or clips.
