Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect and Replace Bulbs

Tools Required: Flathead screwdriver
Remove the brake light assembly by unscrewing the screws and gently pulling it out.
Remove the old bulbs by turning them counterclockwise and pulling them out of the socket.
Insert new bulbs by pushing them into the socket and turning clockwise until secure.
Reinstall the brake light assembly and secure it with screws.

3. Check and Replace Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box under the dashboard on the driver's side.
Identify the brake light fuse (refer to the fuse diagram on the box cover).
Pull the fuse using a fuse puller or pliers. If the metal strip is broken, replace it with a new fuse of the same amperage (usually 10A).
Reinsert the fuse into the fuse box.

4. Test and Replace Brake Light Switch

Tools Required: Socket set
Locate the brake light switch under the dashboard near the top of the brake pedal.
Disconnect the wiring harness from the switch.
Test the switch for continuity using a multimeter. Replace the switch if it does not show continuity when the pedal is pressed.
Install the new switch by connecting the wiring harness and securing it in place.

5. Final Assembly

Reconnect the negative terminal of the battery.
Test the brake lights to ensure they are functioning properly.
