How to Fix Cigarette Lighter in Your Car: 1 Minute to a Functional Car Power Outlet

When your car’s cigarette lighter suddenly stops working, it’s more than a minor convenience issue—these sockets often power essential devices like phone chargers or GPS units. The solution depends on whether the problem lies with the power supply, the socket itself, or your device. Let's walk through how you can systematically fix your car's cigarette lighter:

1. Check Your Device: Start by plugging in a different device. If neither appliance works, it’s likely an issue with the power source or socket.
2. Inspect the Fuse: The most common cause is a blown fuse. Locate your car’s fuse box (consult your owner's manual), identify the fuse labeled for the cigarette lighter or 12V auxiliary power, and check if it appears burnt or damaged. Replace if necessary with a fuse of the same amperage.
3. Examine the Socket: Debris, coins, or rust inside the socket may cause connection failures. Turn off your car and use a flashlight to inspect the socket. Gently clean with a soft brush and use a can of compressed air if necessary.
4. Check the Wiring: If the fuse and socket seem fine, the problem might be faulty wiring behind the unit. This step is a bit more advanced and may require removing the dashboard panel to access the wires. Ensure all connections are secure—if you spot frayed or broken wires, professional repair may be required.
5. Replace the Socket: If everything else fails, consider replacing the cigarette lighter socket itself. Replacement kits are inexpensive and available at auto parts stores. Follow the manufacturer’s instructions for installation.

Tips 1:

Always disconnect your car's battery before working with electrical components to avoid short circuits or injury. Keep spare fuses in your glove box—they’re inexpensive and can save you time and frustration on the road. If you’re unsure about any step, consult with an automotive electrician or your dealership.
