Things You'll Need
Flashlight
Box wrench set
1997 Chevy vehicles employ a brake light switch, bolted to a bracket just forward of the brake pedal arm, to activate the stop lights when you step on the brakes. As with most electrical switches, the brake light switch is prone to short circuits. If you suddenly lose all your brake lights at once, or they won't turn off after you use them, odds are your brake light switch is bad. If you have basic auto repair skills and your 1997 Chevy needs a new brake light switch, you can replace it in less than 20 minutes.
Step 1
Open the 1997 Chevy's driver door, and move the driver's seat as far back as it will go. Lean under the dashboard with the flashlight, and shine the light on the brake pedal arm to locate the brake pedal switch.
Step 2
Unhook the brake pedal wiring pigtail from the Chevy's brake pedal switch by hand. Unbolt the old brake pedal switch from the mounting bracket using the box wrench set.
Step 3
Remove the old brake pedal switch by hand. Insert the replacement brake pedal switch into the brake pedal bracket. Bolt the switch in place with the box wrench set.
Step 4
Plug the brake wiring pigtail into the replacement brake pedal switch by hand. Readjust the driver's seat, and close the door.
