Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shock.

2. Replace Brake Light Bulbs

Tools Required: Socket set, flathead screwdriver (if needed)
Remove the plastic cover or trim from the rear taillight assembly (if applicable).
Twist the bulb socket counterclockwise and pull it out from the assembly.
Remove the old bulb by pulling it straight out of the socket and replace it with a new one.
Reinstall the bulb socket by twisting it clockwise back into the assembly.
Reattach any covers or trim removed.

3. Replace Brake Light Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the brake light fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it; if the metal strip inside is broken, replace it with a new fuse of the same amperage.
Reinstall the fuse by pushing it back into the fuse box.

4. Inspect and Replace Brake Light Switch

Tools Required: Socket set, multimeter
Locate the brake light switch mounted on the brake pedal assembly.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity; replace the switch if it does not show continuity when the pedal is pressed.
Reinstall the new brake light switch and reconnect the electrical connector.
