1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal from the battery to ensure safety while working on the electrical system.

2. Replace Brake Light Bulbs

Tools Required: Screwdriver, replacement brake light bulbs.
Remove the brake light housing assembly by unscrewing the retaining screws.
Carefully pull the housing away from the vehicle.
Twist the bulb socket counterclockwise to remove it from the assembly.
Replace the old bulb with a new bulb (ensure it matches the specifications: usually 7443 for Corolla).
Reinstall the bulb socket into the housing and secure it by twisting it clockwise.
Reattach the brake light housing assembly and secure with screws.

3. Replace Blown Fuse

Tools Required: Fuse puller or needle-nose pliers, replacement fuse.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse related to the brake lights (refer to the fuse diagram on the cover).
Use a fuse puller to remove the blown fuse and replace it with a new one of the same amperage.

4. Inspect and Replace Brake Light Switch

Tools Required: Screwdriver, replacement brake light switch.
Locate the brake light switch mounted on the brake pedal.
Disconnect the wiring harness from the switch.
Remove the switch by unscrewing it from its mounting bracket.
Install the new switch in the same position and secure it with screws.
Reconnect the wiring harness to the new switch.

5. Repair Wiring and Connectors

Tools Required: Multimeter, wire connectors, electrical tape.
Visually inspect all wiring and connectors leading to the brake lights for damage.
Use a multimeter to test for continuity in the wires.
Repair any damaged wires by cutting out the bad section and splicing in new wire using wire connectors.
Insulate any exposed connections with electrical tape.
