- Blown fuse: Check the fuse box for a blown fuse labeled "brake lights" or "stop lights." Replace the fuse if it is blown.
- Faulty brake light switch: The brake light switch is located under the brake pedal. Check the switch for damage or corrosion. If the switch is faulty, replace it.
- Faulty wiring: Check the wiring for the brake lights for damage or corrosion. Repair or replace any damaged wiring.
- Malfunctioning bulbs: Check the brake light bulbs to ensure they are not burnt out. Replace any burnt-out bulbs.
- Bad ground: Check the ground wire for the brake lights to ensure it is properly connected. Clean the ground wire connection if it is corroded or loose.
If you have checked all of these items and the brake lights still do not work, you may need to take your vehicle to a qualified mechanic for further diagnosis and repair.
