Solution

1. Preparation

Gather necessary tools and parts.
Wear safety gloves and eyewear.
Disconnect the vehicle battery to avoid electrical shock.

2. Inspect and Replace Brake Light Bulbs

Remove the tail light assembly by unscrewing the retaining screws.
Gently pull the assembly out and disconnect the wiring harness.
Remove the old brake light bulbs by twisting them counterclockwise and inspecting them for damage.
Replace with new bulbs, ensuring they are properly seated and twist them clockwise to secure.

3. Check and Replace Fuses

Locate the fuse box and remove the cover.
Identify the brake light fuse using the diagram on the fuse box cover.
Pull the fuse out with a fuse puller or pliers and inspect it for continuity.
Replace with a new fuse of the same rating if it is blown.

4. Test and Replace Brake Light Switch

Locate the brake light switch, typically mounted above the brake pedal.
Disconnect the switch harness and use a multimeter to check for continuity when the switch is pressed.
If there is no continuity, remove the old switch by unscrewing it or releasing clips.
Install the new brake light switch by reversing the removal steps and reconnect the harness.

5. Reconnect and Test

Reconnect the vehicle battery.
Test the brake lights by pressing the brake pedal to ensure they illuminate.
Reassemble any components that were removed during the process.
