Solution
1. Preparation
  • Gather tools: Multimeter, flathead screwdriver, socket set, and safety goggles.
  • Ensure the vehicle is parked on a flat surface with the ignition turned off.
2. Inspect and Replace Fuse
  • Locate the fuse box (typically under the dashboard or in the engine compartment).
  • Remove the brake light fuse using a fuse puller or flathead screwdriver.
  • Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.
3. Test Brake Light Switch
  • Locate the brake light switch near the brake pedal.
  • Disconnect the switch connector and use a multimeter to check for continuity when the pedal is pressed.
  • If the switch is faulty, remove it by unscrewing it from the bracket and replace it with a new one.
4. Check Wiring and Connectors
  • Inspect the wiring harness leading to the brake lights for fraying, cracks, or corrosion.
  • If any damage is found, repair the wiring or replace the harness as necessary.
  • Ensure connectors are tightly connected and free of corrosion; clean as needed.
5. Verify Relay Functionality
  • If applicable, locate the brake light relay in the fuse box.
  • Swap the relay with a similar one from another circuit (like the horn) for testing.
  • If the brake lights function with the swapped relay, replace the faulty relay.
