Solution

1. Preparation

Gather all necessary tools and replacement parts.
Disconnect the negative battery terminal to ensure safety.
Tools Required: Socket set, multimeter, screwdriver, replacement brake light bulbs.

2. Replace Brake Light Bulbs

Open the trunk and locate the access panel for the tail light assembly.
Remove the access panel using a screwdriver if necessary.
Twist the brake light bulb socket counterclockwise to remove it from the assembly.
Replace the burnt-out bulb with a new bulb of the same specification (check the owner's manual for bulb type).
Reinsert the bulb socket and twist it clockwise to secure it in place.
Reattach the access panel.

3. Check and Adjust Brake Light Switch

Locate the brake light switch, typically mounted near the top of the brake pedal assembly.
Disconnect the electrical connector from the brake light switch.
Check for continuity using a multimeter; if no continuity is found when the pedal is pressed, replace the switch.
If operational, adjust the switch position to ensure it activates when the pedal is depressed.

4. Inspect and Replace Fuse

Locate the fuse box, usually under the dashboard or in the engine compartment.
Identify the fuse for the brake lights using the diagram on the fuse box cover.
Remove the fuse and inspect it visually. If the metal strip is broken, replace it with a new fuse of the same amperage.
Reinsert the fuse and close the fuse box.

5. Inspect Wiring Harness

Visually inspect the wiring harness leading to the brake lights for any signs of wear, fraying, or corrosion.
Repair any damaged wires using electrical tape or replace the section of the harness if necessary.
Reconnect any loose connectors and ensure all connections are secure.
