Solution

1. Preparation

Tools Required: Socket set, flathead screwdriver, multimeter, fuse puller
Ensure the vehicle is parked on a level surface, and the ignition is turned off. Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Bulbs

Sub-steps:
1. Open the trunk and remove the access panel to the rear light assembly.
2. Twist and remove the bulb socket from the assembly.
3. Pull out the old bulb and inspect it for a broken filament.
4. Insert a new bulb of the same specification (typically 7443 or 1157).
5. Reinstall the bulb socket into the assembly and secure the access panel.

3. Check and Replace Fuse

Sub-steps:
1. Locate the fuse box; it is usually found under the dashboard or in the engine compartment.
2. Identify the brake light fuse by consulting the fuse diagram on the cover.
3. Use a fuse puller or pliers to remove the fuse and inspect it for continuity.
4. If blown, replace it with a new fuse of the same amperage (typically 10A or 15A).
5. Reinstall the fuse and close the fuse box.

4. Test Brake Light Switch

Sub-steps:
1. Locate the brake light switch near the brake pedal.
2. Disconnect the switch connector and use a multimeter to test for continuity when the pedal is pressed.
3. If there is no continuity, replace the brake light switch.
4. Reconnect the wiring harness after replacement.

5. Inspect Wiring

Sub-steps:
1. Visually inspect the wiring from the brake light switch to the rear light assembly for any signs of damage or corrosion.
2. Repair or replace any damaged wiring as necessary.
3. Ensure all connections are secure and free from corrosion.
