The different lights all go through the turn signal light turn switch. If the brake light switch is not working at all then the third brake light would not work. You will need to replace turn signal switch and check brake light switch also and replace it if no third brake light is working.

Chances are, if your brake and turn signals have all gone down, your fuse is as good as gone. You can find your car`s fuses in the fuse box, often underneath the hook or on the kick panel inside the passenger compartment. Your car manual should tell you which fuse is for your brake circuit.
Like all of the lights on and in a vehicle, turn signals rely on a fuse. When the fuse blows, electric power to the turn signals will be shut off entirely. Burnt out bulbs: As with all light bulbs, turn signal lights can burn out and die.
A faulty switch can be one of the main reasons why the turn signals don`t work. It is also good to check the parking lights, which usually utilize the turn signal bulbs. If the parking lights and hazards come on, but that side doesn`t illuminate when you hit the switch, then it`s a circuit problem.
When we use the turn signal switch, it cancels the brake light signal, on the side selected. If it did not, the lights would stay on and not flash. A bad turn-signal switch may interrupt the brake light circuit when it should not. A broken wire to or from the switch may also cause the lower brake-lights not to work.
And because the taillights and brake lights do not share the same circuit, confirming the ground as a potential cause is not a task that needs much analysis.
It is a 15amp fuse that powers the stop light switch on the brake pedal. The brake light switch sends power to rear brake lights.
It is usually located under the driver`s side of the dash, and is wired in-line with the turn signal lever and hazard switch buttons.
Bulbs in need of replacement – Like any other bulb, indicator bulbs have a finite life and will eventually need replacement. Indicator bulbs can often blow from old age, excess vibration or a faulty regulator in the alternator that causes high car battery voltages and over charging of the cars battery.
Hazard lights and turn signals use the same bulb, so it is not the bulb, the lamp, or the cables to them. Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse.
A brake light switch is an electrical switch that turns your brake lights on when you hit the brakes. It`s an integral part of your braking system and lets the driver behind you know that you`re slowing down. It also has a direct influence on your ABS, cruise control system, and more.
A blown fuse. If the bulb or socket isn`t the problem, the next check is the fuse or the light switch. Fuses for everything electrical, including your tail lights, are always found in the fuse box. They are usually located under the hood or in the cabin.
Check the fuse.
A blown fuse usually causes both lights to go out. On newer cars, the tail lamps can be fused separately and/or each bulb or shared circuit can be fused. A fuse can be blown due to other problems, so you`ll need to check more than just the fuse, but it`s the right place to start.
The Light Control Module (LCM) is an important component of a vehicle because it controls all of the car`s lights, as well as the horn function.
Like all fuses, the brake light system fuse can be found in the power distribution center, which is under the dashboard or tucked away underneath the hood. Never heard of the power distribution center? It`s just the technical name for a fuse box.
You only need a Brake-Lite Relay if you`re installing a supplemental towed vehicle braking system that pushes or pulls the brake pedal. With the engine off, step on your brakes. If the brake lights do not illuminate, you do not need a Brake-lite Relay.
Our two pin flasher relay is truly universal! Suitable for 6V or 12V systems and fully functional with LED or standard incandescent bulbs.
Check for a blown circuit fuse. Verify that circuit connections are not loose, corroded, or unplugged. Inspect the wiring harness or terminals for the rear section of the circuit. Check for a bad connection between the turn signal switch and the flasher or between the flasher and the ignition switch.
Reasons Why Tail Lights not Working When Brake Lights are:
Faulty fuse—when troubleshooting this issue, the first piece of professional advice you`ll usually receive is to check the tail light fuse. Often, a bad fuse is to blame. Wiring—once again, wiring issues are key to pinpointing this problem.

In many newer cars there is one light bulb per tail light. There are two filaments in each light bulb. One is for your brake light and one is for your turn signal.
The most common reasons your brake light is on: The Parking Brake is engaged. Brake Fluid is low or leaking. Worn brake pads.
