* Brake light switch: The brake light switch is responsible for turning on the brake lights when the brake pedal is depressed. If the brake light switch is faulty, the brake lights will not work even if the fuses and bulbs are good.
* Wiring: The wiring for the brake lights may be damaged or disconnected, preventing power from reaching the brake lights. Check the wiring for any loose or damaged connections, and make sure that the ground wire is properly connected.
* Brake light relay: Some vehicles have a brake light relay that controls the power supply to the brake lights. If the brake light relay is faulty, the brake lights will not work even if the fuses, bulbs, and brake light switch are good.
* Turn signal switch: If your vehicle has a combination turn signal and brake light switch, a faulty switch can also cause your brake lights to stop working.
If you have checked all of these things and the brake lights still do not work, it is recommended that you take your vehicle to a qualified mechanic for diagnosis and repair.
