Solution
1. Preparation
  • Gather tools: socket set, multimeter, screwdriver, and possibly a replacement brake light switch.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Adjust Brake Light Switch
  • Locate the brake light switch, typically found above the brake pedal.
  • Remove any covering or panel obstructing access to the switch.
  • Check the switch for proper alignment. If misaligned, adjust it so that it fully disengages when the brake pedal is not pressed.
  • Reconnect the battery and test if the brake light turns off.
3. Test Brake Light Switch
  • With the multimeter, set it to continuity mode.
  • Disconnect the electrical connector from the brake light switch.
  • Place the multimeter probes on the switch terminals. Press the brake pedal; the multimeter should indicate continuity when the pedal is pressed and none when released.
  • If the switch fails this test, proceed to replace it.
4. Replace Brake Light Switch (if necessary)
  • Remove the faulty brake light switch by unscrewing it from its mount.
  • Install the new switch by reversing the removal steps, ensuring it is securely fastened.
  • Reconnect the electrical connector to the switch.
5. Final Inspection
  • Reconnect the negative battery terminal.
  • Test the brake lights by pressing the brake pedal and ensuring they turn off when released.
  • Replace any panels or coverings removed during the process.
