The brake light switch is a normally open switch that controls the operation of the brake lights. It is located near the top of the brake pedal and is attached to a bracket. When the brake pedal is applied, the pedal arm moves away from the switch and a spring-loaded plunger closes the circuit to the brake lights. Models equipped with cruise control use a dual-purpose brake light switch that also deactivates the cruise control system when the brake pedal is depressed. To check the brake light circuit, start by checking the fuse and replacing it if necessary. Then, verify that there is voltage to the switch and repair any open or short in the power wire. If the brake lights still don't come on, check for continuity between the switch terminals and replace the switch if necessary. If there is continuity, check for power to the brake light bulb sockets and replace the bulbs if voltage is present. If voltage is not available, check the wiring for an open circuit and repair as necessary. To replace the brake light switch, depress and hold the brake pedal, then rotate the switch counterclockwise to remove it from the mounting bracket. Unplug the electrical connector and remove the switch from the vehicle. Pull the switch plunger outward until it is fully extended. Depress the brake pedal and install the switch in the bracket, rotating it clockwise to lock it into place. Gently pull back on the brake pedal until it stops moving to adjust the switch, being careful not to use excessive force. Finally, plug the electrical connector into the switch.

Rotate the switch about 30 degrees counterclockwise and remove it from its bracket. Disconnect the electrical connector for the brake light switch.
