What to Do When the Car Cigarette Lighter Has No Power?
4 Answers
If other electrical devices in the car are functioning normally but the cigarette lighter is not working, it indicates that the cigarette lighter has no power. When the cigarette lighter in the vehicle has no power, you can first try connecting another cigarette lighter. If it works, the issue lies with the lighter itself, and you can simply replace it. Another possible reason is a blown fuse in the cigarette lighter, which can be resolved by replacing the fuse. Here are the steps to troubleshoot a cigarette lighter with no power: 1. First, check if the cigarette lighter itself has no power. Try using the original car's cigarette lighter. If the original one also has no power, the fuse for the cigarette lighter might be blown. Visit a nearby car repair shop to replace it. 2. If the cigarette lighter has power but the car charger does not, it means the car charger is damaged and needs to be replaced. 3. Additionally, when drawing power from the cigarette lighter, if using an inverter, avoid using electrical devices exceeding 120 watts, as this could blow the cigarette lighter's fuse.
The car cigarette lighter has no power? Last time my car had the same issue, it was usually the fuse. Locate the fuse box inside the car, typically found under the steering wheel or in the engine compartment. Check the manual for the fuse labeled 'cigarette' or 'accessory'. Pull it out to see if it's blown; if so, replace it with a new one of the same amperage. It might also be poor contact in the plug—try gently scraping it with a hard object before reinserting. Also, check for aging wiring or short circuits, but avoid tampering with the electrical system yourself to prevent electric shock. Avoid plugging in high-power devices like power banks or heaters to prevent overload and damage. If all else fails, drive to a nearby repair shop for a professional check—safety first.
If the cigarette lighter has no power, don't panic—it might be a simple issue. I've learned a lot from my car-savvy friends: pop the hood and locate the fuse box. The fuse for the cigarette lighter is usually blue or red—pull it out and check. If it's blown, just buy an identical one at an auto parts store. Next, check if the plug is loose or oxidized; scrape the metal contacts and try again. Deeper issues could involve a faulty control module or damaged wiring—use a multimeter to measure voltage for diagnosis. Always disconnect the power before working to avoid short circuits or injuries. This minor fix might just cost a few bucks for a new fuse, but if the problem keeps recurring, inspect the power supply system to avoid travel disruptions.
When the cigarette lighter suddenly loses power, I believe it's best to start with basic checks. Examine the common causes of a blown fuse and try replacing it. Check if the plug has any dirt or deformation and clean it if necessary. Then investigate whether the connecting wires are burnt out or aged, and seek professional inspection if needed. For safety, avoid plugging in too many devices while driving to prevent overload, and wear gloves when repairing. Minor issues don't affect driving, but be cautious at night or when power is low.
