If the automatic headlights in your car aren’t working, don’t worry. You don’t have to be a master mechanic to troubleshoot and fix the issue. I will guide you through the basic steps needed to fix automatic headlights that are not working and then offer advice on maintaining them.
- Blown Fuse. So, you may already know this, but fuses are actually safety devices that are there to protect the electrical circuits in your car. They work by having a small piece of wire that melts and breaks the circuit if the current flowing through it becomes too much.
- Faulty Relay. A relay is like an electrical switch that opens and closes circuits, either with mechanical or electronic magic. In your car, relays take charge of the high current that powers the headlights, letting them turn on and off.
- Worn-Out Headlight Switch. This is the switch with which you turn on and off the headlights, if they aren’t automatically turned on and off when you start or stop the car.
- Damaged or Corroded Wiring. If the wiring to the headlights gets messed up or corroded, it can stop the electrical current from reaching the headlights.
If only one of your headlights is not working, it’s likely due to a burned-out bulb, a faulty socket, or a wiring issue specific to that headlight. How do I know if my headlight relay is faulty? You can test if your headlight relay is faulty by swapping it with a similar relay, like the horn relay, to see if the headlights start working.
After examining the headlight, it is clear that one headlight is not working due to a fault in the wiring, a broken bulb, a burned-out fuse, or a faulty headlight switch. To determine the cause of the problem, further, inspection is necessary.
