Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the negative terminal of the battery to avoid electrical shock.

2. Replace Brake Light Bulbs

Sub-steps:
1. Open the trunk and locate the taillight assembly.
2. Remove the access panel or screws securing the taillight assembly.
3. Twist and remove the bulb socket from the assembly.
4. Pull out the old bulb and replace it with a new bulb (ensure it is the correct wattage).
5. Reinsert the bulb socket and secure the assembly back in place.

3. Inspect and Replace the Brake Light Fuse

Sub-steps:
1. Locate the fuse box (typically under the dashboard or in the engine compartment).
2. Identify the brake light fuse using the fuse diagram.
3. Pull the fuse using fuse pullers or pliers and inspect it for continuity.
4. If blown, replace it with a fuse of the same amperage rating.

4. Replace the Brake Light Switch

Sub-steps:
1. Locate the brake light switch, usually mounted on the brake pedal assembly.
2. Disconnect the wiring harness from the switch.
3. Remove the mounting screws holding the switch in place.
4. Install the new brake light switch and secure it with screws.
5. Reconnect the wiring harness and ensure proper alignment.
