- Blown fuse: Check the fuse box for a blown fuse, specifically the fuse that controls the turn signals, hazard lights, and brake lights. Replace the blown fuse if necessary.
- Faulty turn signal switch: The turn signal switch is responsible for activating the turn signals and hazard lights. If the switch is faulty, it can cause the turn signals and hazard lights not to work.
- Faulty brake light switch: The brake light switch is responsible for activating the brake lights when the brake pedal is pressed. If the switch is faulty, the brake lights will not work.
- Wiring issues: There may be a problem with the wiring that connects the turn signal switch, brake light switch, and lights. Check the wiring for any damage or loose connections and repair as necessary.
- Faulty bulbs: Check the turn signal bulbs, hazard light bulbs, and brake light bulbs to ensure they are not burned out. Replace any burned-out bulbs.
