1. Preparation

Gather tools and safety equipment.
Tools required: Screwdriver set, multimeter, replacement bulb if necessary, fuse puller.
Safety warnings: Ensure the vehicle is turned off and keys are removed from the ignition.

2. Inspect and Replace the Brake Light Bulb

Open the trunk and locate the access panel for the rear brake lights.
Remove the access panel by unscrewing or unclipping it.
Carefully twist the brake light socket counterclockwise to remove it from the assembly.
Pull out the old brake light bulb from the socket and inspect it for damage.
Insert a new bulb (ensure it’s the correct type) into the socket until it clicks into place.
Reinsert the socket into the brake light assembly and twist it clockwise to secure it.
Replace the access panel and secure it.

3. Check and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse associated with the brake lights (refer to the fuse box diagram).
Use a fuse puller to remove the fuse and inspect it for damage.
If the fuse is blown, replace it with a new fuse of the same amperage.
Reassemble the fuse box cover.

4. Test the Brake Light Functionality

Have an assistant press the brake pedal while you observe the rear brake lights.
If the brake lights now function, the issue is resolved.
