30 August 2024 Cigarette lighter in car not working: how to fix it
Most cars come equipped with a cigarette lighter, which can also be used to power other devices such as sat navs and phones. However, it can be frustrating to find out that your cigarette lighter isn't working when you need to charge your phone or power another device. In this situation, it's important to know what steps you can take to get your devices charged again.
Why is my cigarette lighter not working?
If your car's cigarette lighter or the 12V power socket is not working, it could be due to several reasons. The most common cause is a blown car fuse. You can check and install a new car fuse by locating your car's fuse box, which is usually under the dashboard or in the engine compartment. Look for the one that is labelled for the cigarette lighter or accessory socket, and if it is blown, replace it with a new one of the same amperage.
If you have checked the fuse and it is not blown, the problem might be caused by faulty wiring. To investigate, you can examine the wiring connected to the rear of the socket for any signs of damage, wear, or disconnection. If you identify any issues, you can fix them by either repairing or replacing the defective wiring. Lastly, a faulty cigarette lighter socket may be causing the issue. You can test it with another accessory to see if it works. If it still doesn't work, the entire socket assembly may have to be replaced.
