1. Check the Headlight Switch:
- Make sure the headlight switch is turned to the "On" position.
2. Check the Headlight Fuses:
- Check the fuses for the headlights in the fuse box under the hood or under the dash. Replace any blown fuses with fuses of the same amperage.
3. Check the Headlight Bulbs:
- Make sure the headlight bulbs are properly seated in their sockets and are not burned out. You might replace them if they are damaged.
4. Check the Headlight Wiring:
- Inspect the wiring for the headlights to ensure that there are no loose connections or damage. Any loose connections should be reconnected or repaired.
5. Check the Headlight Relay:
- Some models have a headlight relay that controls the power to the headlights. Check this relay to ensure that it is working properly. If it's faulty, replace it.
6. Check the Headlight Switch:
- The headlight switch could be faulty. Test it with a multimeter to ensure it is sending power to the headlights.
7. Check the Headlight Grounding Points:
- Check the grounding points for the headlights to ensure they are clean and secure. Any corrosion should be cleaned off, and loose connections should be tightened.
8. Check the Turn Signal Switch:
- If the headlights work only when the turn signal is activated, the turn signal switch might be faulty. Test it or have it tested to confirm.
Remember that electrical issues can sometimes be complex. If the problem persists or if you are unsure about any of these steps, it is best to consult with a qualified auto technician or mechanic.
