Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the battery to prevent any electrical shorts.

2. Replace Brake Light Bulbs

Sub-steps:
1. Access the brake light assembly by opening the trunk and removing the access panel.
2. Twist and remove the brake light bulb socket from the assembly.
3. Replace the old bulb with a new bulb (ensure it is the correct type).
4. Reinsert the bulb socket and secure it back into place.

3. Check and Replace Brake Light Fuse

Tools Required: Fuse puller or needle nose pliers
Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Identify the brake light fuse using the diagram on the fuse box cover.
3. Remove the fuse and inspect it; replace it with one of the same amperage if blown.

4. Test Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch mounted near the top of the brake pedal.
2. Disconnect the electrical connector from the switch.
3. Use a multimeter to test continuity; the switch should show continuity when the pedal is pressed.
4. If faulty, remove the switch and replace it with a new one.

5. Inspect Wiring and Connections

Sub-steps:
1. Visually inspect the wiring harness leading to the brake lights for wear or damage.
2. Repair any damaged wires with appropriate wire connectors or electrical tape.
3. Ensure all connectors are clean and secure.
