First, check your stop lamps fuse. If that's good your brake light switch is probably bad. This switch is mounted on the bracket that the brake pedal pivots on at the top of the brake pedal. It will have a plunger which, when the brake pedal is depressed, extends & turns on your brake lights. It will have at least one two way connector pluged into it. If you have cruise control it may have a second two way connector pluged into it as well to cancel the cruise control when you tap the brakes. To test the switch, unplug the connector & "jump" the wires. In other words, connect the two wires together. If your brake lights come on, switch is bad. HTH. -Jim
