So, before we talk about the fixes, let’s first look at some common reasons why a car cigarette lighter stops working.

Faulty Fuse or Bad Wiring Issues

A car cigarette lighter can stop working due to bad wiring or a faulty fuse, which is one of the most common reasons for this issue. When the fuse is blown, it disrupts the socket’s function, making it difficult to handle extra amperage and potentially leading to a complete failure. 

Additionally, plugging inappropriate devices into the lighter can overload the circuit, causing it to fail or stop functioning properly. If these problems are ignored, they can impact the whole electrical system of the vehicle. 

Blown Socket

A blown socket is a common cause of a cigarette lighter not working, affecting its ability to function properly. Just like a faulty charger port, a damaged socket may fail to receive electricity, making it unusable. This problem can disrupt essential car functions, especially if you rely on the lighter for charging devices. 

Obstructions In The Cigarette Lighter

A common issue with vertically installed lighters is the accumulation of small particles, food crumbs, or other objects inside the socket, which can disrupt the electrical supply. This can cause problems not only with lighting but also when trying to charge a phone. When debris builds up, it prevents proper contact, making the lighter ineffective.

Bad Quality Charger

A bad charger can lead to fuse failure and damage to your car’s electrical system. Since different manufacturers use various names for charging devices and accessory outlets, checking the vehicle’s manual is crucial to locate the right fuse and avoid causing damage. Some cars label the fuse box under the hood with terms like LTR, cigar lighter, cigarette lighter, AUX power point, 12V outlet, or 12V power point. 

If the fuse is burnt or broken, you can use a gripper or your fingers to pull it out and check for metal indicators that confirm if the fuse is faulty. Replacing it with a new fuse ensures the lighter functions properly and restores power for charging devices.

Ways To Fix Car Cigarette Lighter Not Working

Now that you know some common reasons why your car cigarette lighter may not be working properly, it’s time to explore some simple ways to fix it.

1. Inspect the Lighter’s Fuse

To check if the cigarette lighter’s fuse is faulty, use a circuit tester to confirm if it’s receiving power. Start by placing the clip end of the tester on the outer frame of the socket and hold it securely, as clipping can sometimes be difficult. Next, use the longer end of the tester to touch the back of the socket. 

If the test light turns on, it means the circuit is working. However, if it doesn’t, the problem lies in the fuse, which may need to be replaced or repaired. In this case, resolving the issue in time ensures your lighter functions properly and prevents further electrical problems.

2. Fixing a Damaged Lighter Fuse

A car cigarette lighter fuse can blow due to multiple failures, often caused by an item that consumes more amperage than the design allows. This situation can lead to a damaged socket and electrical issues in the circuit. Typically, circuits are fused at 10A or 15A, but some larger schematics or inverters may demand more current, leading to an overload. When the fuse blows, it can fail to power electrical appliances and may even cause the inverter to stop working.

 The easiest step is to observe the results and replace the 12V cigarette accessory fuse if necessary. If the fuse immediately blows again, there is a deeper problem in the circuit that needs to be discovered and fixed. If you have already encountered this issue and the fuse initially blew, it may indicate a failed component, requiring a thorough inspection to prevent further damage.

3. Inspect the Inside of the Lighter

If the lighter’s fuse is working fine but the cigarette lighter doesn’t work, there may be an internal problem that needs attention. Check inside for debris, random objects, or dust that could be causing an issue. These obstructions can prevent proper contact, affecting functionality. 

To resolve this, carefully take out the inner parts and clean them thoroughly. Regular cleaning helps maintain efficiency and ensures the lighter operates properly. 

4. Lighter’s Inspection

If the cigarette lighter is still not working after replacing the fuse and cleaning the socket, it likely means there is an underlying fault. Start by carefully pulling out the lighter’s portion from the socket and checking for any burned areas, debris, or other issues that could signal burning signs or a short-circuited component. If there is visible damage, you need to replace it with a new one to restore functionality.
