How to fix car lighter fuse at Home?

Before we start troubleshooting, it’s important to understand why it’s crucial to address the problem with the cigarette lighter in your car. Here are a few common reasons:

  1. Avoiding Costly Repairs: By fixing it yourself, you can save money on expensive repairs done by professionals.
  2. Convenience: You can use the cigarette lighter to charge your gadgets anywhere you go.
  3. DIY Maintenance: You can take care of minor issues, like blown fuses, by yourself.
  4. Safety Concerns: It’s important to replace any faulty components to minimize potential hazards.

Now, let’s look at some detailed ways to resolve the problem of the car cigarette lighter not working.

1. Check The Lighter’s Fuse

Identifying a faulty fuse is often the initial step. Employ a circuit tester:

Check The Lighter’s Fuse

To check if the fuse for the cigarette lighter is working, you can use a circuit tester. First, attach the clip end of the tester to the outer frame of the socket. If it’s hard to attach, hold it in place.

Next, try to touch the back of the socket with the longer end of the tester.

If the light on the tester turns on, it means the lighter is getting power. But if the light doesn’t turn on, then the problem is with the fuse. You’ll need to replace or repair it as soon as possible.

How to fix a blown fuse for the lighter

Sometimes, the fuse in your car can blow due to different issues. If you find that the problem is specifically with the lighter socket, then the situation can be resolved.

  • If not, there might be a problem somewhere else. It’s also possible that you plugged in an item that requires more power than the circuit is designed for.
  • Normally, fuses are rated at 10 or 15 amps, especially in smaller circuits. However, some inverters require more power than that. In such cases, plugging in electrical appliances may blow the fuse and cause the inverter to stop working.
  • The easiest next step is to replace the cigarette lighter fuse or the fuse for the 12V accessory socket and see what happens.
  • If the fuse blows immediately, there is a problem somewhere in the circuit. Also, if everything was working fine before but the fuse blew when you plugged in the inverter, then the inverter might be faulty.
  • Considering the limitations of inverters, you might want to use an inverter that’s directly connected to the car battery or fuse.

2. Check The Lighter’s Inside

If the fuse is intact, delve into the lighter’s internals for potential issues. Internal debris could be the culprit. Clean the components meticulously:

If the lighter isn’t working, you should check inside it. The problem might be inside the lighter because of dirt or other things inside.

To fix it, you need to remove the inner parts and clean them well. If cleaning doesn’t solve the problem, you’ll need to inspect it more closely.

3. Lighter’s Inspection

If your cigarette lighter doesn’t work even after changing the fuse and cleaning it, then the problem is with the lighter itself. Take out the part of the lighter that goes into the socket and check for any burned areas or debris.

If you find any signs of burning, it means the lighter may have short-circuited and you should get a new one. Also, make sure to clean out any debris and other things that could cause problems later on.

4. Remove Unnecessary Plugged-in Devices

You can try fixing the problem by unplugging any devices that are not needed.

Remove Unnecessary Plugged-in Devices

Car lighters are sockets in cars that provide power. They were originally created for people to smoke in cars, but if you plug a 12-volt DC device into the lighter socket, it creates an electrical connection.

If something like food crumbs, stones, or dirt gets inside the plug, it can disrupt the electrical connection. This often happens with upright cigarette lighters.

5. Test or Replace the Lighter Socket

To see if there’s electricity in the cigarette lighter socket, follow these steps:

  1. Turn on the car ignition before testing, as some lighters won’t work when the key is off.
  2. Set the multimeter to measure DC voltage. Connect the red wire to the socket labeled “V” and the black wire to the socket labeled “COM.”
  3. Touch the metal end of the red wire to the round part at the bottom of the socket. Place the metal end of the black wire against the side of the socket.
  4. Look at the voltage displayed on the multimeter while the wires are touching the relevant parts of the socket.
  5. If the voltage is significantly less than 12 volts, then the socket is probably the cause of your lighter not working. It’s recommended to replace it as soon as possible.

The cost of fixing this issue can range from $50 to $150, depending on how severe the problem is and the complexity of your car’s electrical system.

6. Check if the Charger or Plug is Failed

Finally, the plug itself could be broken. Make sure the electronic parts inside the charger, lighter, or other 12-volt devices are not damaged, and check if the springs inside the plug you put into the socket are not worn out.

If the socket needs fixing, get help from an expert. They can help you repair it so that your car’s cigarette lighter can charge your phone again.
