Brake lights. Not on

Could be your brake light switch. It's located under the dash where the brake pedal mounts to the firewall. Or as simple as your brake light bulbs are just burned out.

First check your fuses then the bulbs then the stop light switch under the steering wheel.

If the turn signals work it isn't the bulbs because the brake lights and turn signals use the SAME filament inside the bulb. UNLESS you're car has the Amber (Orange colored ) lenses in the rear. VERY UNLIKELY both brake light bulbs could burn out at the same time I've seen but not very often.

The wire can also break off going to the stoplight switch. Happened to me twice. Crimped on a new piece of flexable wire and new spade terminal. Not sure if the LCM affects this or not.
