How to Install a Brake Light Switch in a 1999 Chevy Suburban

Properly installing a brake light switch on a 1999 Chevy Suburban will enhance your peace of mind while driving knowing that you're instantly alerting other drivers when you apply the brakes. The switch closes when the brake pedal arm pushes down on the button in the top of the switch each time you step on the brakes. Once the switch closes, it sends an electronic signal to the brake light bulbs that turns them on. Anyone whose handy with a wrench and has 10 minutes of free time can install a new brake light switch on a 1999 Chevy Suburban.

Things You'll Need

  • Flashlight
  • Box wrench set
  • Helper
  • Move the Suburban's driver seat as far back as it will go to allow better access to the driver's foot well. Lean into the driver's foot well and shine the flashlight above the brake pedal to illuminate the brake pedal arm and the brake light switch.

  • Disconnect the Suburban's brake light circuit pigtail from the body of the old brake light switch by hand. Remove the old brake light switch from the brake light switch mounting bracket with the box wrench set.

  • Pull the Suburban's old brake light switch off the brake light switch mounting bracket by hand and replace it with the new switch.

  • Tighten the Suburban's new brake light switch onto the brake light switch mounting bracket using the box wrench set. Plug the brake light circuit pigtail into the body of the new switch by hand.

  • Step on the Suburban's brake pedal while your helper looks at the brake lights to ensure they're all working as designed.
