Your car’s 12V outlet, often called the cigarette lighter, is essential for powering devices like phone chargers, GPS units, and dashcams. When it stops working, it can be a real inconvenience. This comprehensive guide will help you diagnose and fix common cigarette lighter car adapter issues, empowering you to get your power back on the road.
Similar to how to fix 12v outlet in car, many issues can be resolved with simple troubleshooting. Before you start taking things apart, check the simplest things first.
Why is my cigarette lighter car adapter not working?
Several factors can cause a malfunctioning cigarette lighter car adapter. Understanding these common culprits is the first step towards a solution. These issues can range from a simple blown fuse to a more complex wiring problem.
Common Cigarette Lighter Problems and Solutions
Blown Fuse
This is the most common culprit. Locate your car’s fuse box (usually under the dash or in the engine compartment) and consult your owner’s manual to identify the correct fuse for the cigarette lighter. Replace the blown fuse with one of the same amperage. Never use a higher amperage fuse as this can cause damage to the wiring.
Loose or Damaged Wiring
Sometimes, the wiring connecting the cigarette lighter to the fuse box can become loose or damaged. Inspect the wiring for any visible breaks or loose connections. If you find any, carefully reconnect or repair the wiring. This may require some basic electrical knowledge or professional assistance.
Faulty Cigarette Lighter Socket
The socket itself can wear out over time, especially with frequent use. If the metal contacts inside the socket are bent or corroded, they may not make proper contact with the adapter. Try cleaning the socket with a small brush or compressed air. If that doesn’t work, you may need to replace the socket entirely.

Damaged Car Adapter
The problem might not be with the car’s cigarette lighter but with the adapter itself. Try a different adapter to see if it works. If the new adapter works, the original one is likely faulty. If the new adapter also doesn’t work, it points to an issue with the vehicle’s power outlet. You can also try the original adapter in a different vehicle’s 12v outlet to isolate the problem.

Short Circuit
A short circuit in the device you are plugging into the cigarette lighter can also cause it to stop working. Try plugging in a different device to see if the problem persists. If the cigarette lighter works with a different device, the original device is likely the source of the short circuit.

How do I test my car cigarette lighter?
A simple way to test your car’s cigarette lighter is with a multimeter. Set the multimeter to DC voltage and touch the positive probe to the center contact of the lighter socket and the negative probe to a metal ground in your car. With the ignition on, you should see a reading of around 12 volts. This procedure is also useful when addressing issues with fixing your car cigarette lighter.
Can I fix my cigarette lighter myself?
Many cigarette lighter issues can be fixed with basic DIY skills. However, if you are uncomfortable working with electrical systems, it’s always best to consult a qualified mechanic.
Fixed Installation Options for Consistent Power
For devices requiring consistent power, consider exploring fixed installation car power adapters. These options bypass the cigarette lighter entirely and offer a more permanent solution.
Conclusion
A malfunctioning cigarette lighter car adapter can be frustrating. However, by understanding the common causes and solutions, you can often fix the problem yourself and restore power to your essential devices.
