  1. step : Diagnosis (1:00)
    • Check the bulbs if one or more of your brake lights are still working.
    • If none of them are working at all, you could have a bad brake switch or a blown fuse.
    • To rule out a blown fuse, check your fuse box and use the manual to identify which fuses are responsible for the brake lights.
    • If it’s not a bad bulb or blown fuse, you can go on to replace the brake switch.
  2. step : Uninstall the old brake switch. (3:50)
    • Under the dash, unclip the yellow clip securing the brake switch.
    • Unplug the brake switch.
    • Make sure not to lose the little bushing on the mounting, as they are prone to flying away.
    • Unplug the brake switch from the wiring harness.
  3. step : Install the new brake switch. (5:10)
    • Plug in the new switch and secure with the little yellow plastic clip.
    • Connect the wiring harness.
    • Again, ensure all flying bushings are firmly where they should be and all small parts are accounted for.
