Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
2. Inspect and Adjust the Brake Light Switch
  • Locate the brake light switch, typically found above the brake pedal.
  • Check if the switch is misaligned; it should be pressed in when the pedal is released.
  • If misaligned, adjust the switch so that it properly engages when the pedal is not pressed.
3. Test the Brake Light Switch
  • Reconnect the battery temporarily.
  • Press the brake pedal and observe the brake lights.
  • If the lights remain on, use a multimeter to check continuity at the switch:
    • Disconnect the switch connector.
    • Set the multimeter to the continuity setting.
    • Probe the switch terminals; it should show continuity when the pedal is pressed and none when released.
  • If the switch fails the test, proceed to replace it.
4. Replace the Brake Light Switch (if necessary)
  • Remove the faulty brake light switch:
    • Disconnect the wiring harness.
    • Unscrew or unclip the switch from its mount.
  • Install the new brake light switch:
    • Position the new switch in place.
    • Secure it with screws or clips.
    • Reconnect the wiring harness.
5. Final Assembly and Testing
  • Reconnect the negative battery terminal.
  • Check the operation of the brake lights by pressing the brake pedal.
  • Ensure that the lights turn off when the pedal is released.
