- Blown fuse
- Bad bulb
- Faulty switch
- Faulty wiring
- Failed relay
Troubleshooting steps:
1. Check the fuse. The fuse for the headlights and brake lights is located in the fuse box under the hood. If the fuse is blown, replace it with a new fuse of the same amperage.
2. Check the bulbs. If the fuse is not blown, check the bulbs. To do this, turn on the headlights and brake lights and look at the bulbs. If any of the bulbs are not lit, replace them with new bulbs.
3. Check the switch. The switch for the headlights and brake lights is located on the steering column. If the switch is not working properly, it will not send power to the headlights and brake lights. To check the switch, turn on the headlights and brake lights and wiggle the switch. If the lights flicker or turn on and off, replace the switch.
4. Check the wiring. If the switch is not the problem, check the wiring. To do this, look for any damaged or loose wires. If you find any damaged or loose wires, repair them.
5. Check the relay. The relay for the headlights and brake lights is located in the fuse box under the hood. If the relay is not working properly, it will not send power to the headlights and brake lights. To check the relay, swap it with another relay. If the lights work with the new relay, replace the old relay.
If you have tried all of these steps and the lights still do not work, you may need to take your vehicle to a mechanic.
