If your cigarette lighter no longer works, one of the first steps to consider is cleaning it. Debris and contaminants can often accumulate in the socket, preventing proper electrical contact. How do you clean a cigarette lighter properly? Use a toothpick to remove any stuck pieces and a vacuum cleaner to remove any remaining debris. Make sure not to use metal objects to avoid short circuits. If your car cigarette lighter no longer works even after cleaning, it may be necessary to check the fuse or wiring connections. Sometimes, the problem can be more complex and require professional intervention. The cost of car cigarette lighter repair can range from $50 to $100 for simple problems like a damaged socket, but wiring issues can result in higher costs. However, when it comes to a wiring fault, only a mechanic can fix it for you. However, in 90% of cases, a blown fuse is the culprit. Today, tout-reparer.froffers you its guide: How to repair a cigarette lighter? Repairing a broken and faulty cigarette lighterRepairing a cigarette lighter is not a difficult task, but it is an electrical component, and as long as you approach it carefully, you should be able to do it yourself. Faulty cigarette lighter The cigarette lighter is a component that doesn’t give up easily. Most of the time, the problem isn’t with the plug at all. Your cigarette lighter or charger, whatever product you use, could be the source of the issue.
So start by checking that the product isn’t faulty. If you’re using a cigarette lighter, inspect the coil face. Check if there is any tobacco residue stuck to the coil or if the coil face itself is broken. The only way to check the integrity of the cigarette lighter is to plug it into another car and test it there. Or perhaps you’re not using a lighter but a phone charger. In this case, it could be the charger cable or the contact points that are at fault. In the case of a mobile charger, there are three contact points, one in the center and two on each side. They are spring-loaded to fit snugly into the socket.
Again, the only solution is to check your charger in another car to confirm that the problem isn’t with the contact points. You can also try another charger if you have one. Repair your fuse As I mentioned earlier, when it comes to blown cigarette lighters, the problem lies with the fuse in at least 90% of cases.
So, if your charger or cigarette lighter isn’t the problem, you can move on to the fuse immediately. There could be several reasons why your fuse has blown.
First, it could be because a coin fell into the outlet. If not, it could be because you plugged in a device that drew more current than the outlet can handle. In this case, your only option is to replace the fuse. The circuit behind the outlet is designed to handle a current of 10 to 15 V, which isn’t much.
But if you used a power inverter on the outlet, chances are it wasn’t designed to maintain the current at the level mentioned above, and any electronic device plugged in could blow the fuse.
Once a new fuse is installed, one of the following situations may occur:
If the fuse blows all at once, there may be a short circuit.
If the fuse blows after you plug in the cigarette lighter, the problem lies with the cigarette lighter.
You plug in the inverter and the fuse blows: the problem lies with the inverter.
For cigarette lighter inverters, it’s best to choose one that plugs directly into the battery.
Clean the inside of the outlet
Contaminants and debris constantly enter the outlet. Coins often fall into the outlet, and if left undetected, they can cause a short circuit.
While non-metallic debris won’t cause a short circuit, it can prevent the plugs from making contact with the outlet.
Remove the accessory from the outlet and clean any pieces stuck inside.
However, be careful before removing them because the circuit may still be hot and cause a short circuit. Be careful not to use metal objects to clean the outlet.
Use a toothpick to dislodge stubborn pieces and vacuum them to remove them. Otherwise, if you know how to remove the socket, take it out and clean it thoroughly.
If the socket works even after all these steps, you might want to check if the socket itself is problematic.
Damaged Socket
A damaged socket is another common cause, especially on older cars. Over the years, the metal parts are susceptible to corrosion.
Bent and broken points are also common and prevent current flow.
A question I often see is:
How do I repair
a car cigarette lighter socket? Here’s how.
Check the bottom of the socket, where moisture accumulates; you can often see rust there.
Start by removing the fuse.
Then, clean off the rust and repair the contacts if they are deformed.
Reinsert the fuse and check if it works.
You may need to replace the socket if it still doesn’t work.
If the next question you’re asking is:
How do I replace your car’s cigarette lighter?
Let me ask you to stop here. You shouldn’t replace it unless you’re a mechanic yourself. If not, ask an expert to do it for you.
Disconnected Wire
There’s a reason I left this point last. Even if you have the technical and theoretical knowledge to handle it, it’s best left to experts, like your mechanic.
To begin, you’ll need a test light or voltmeter. Place the test light on the brass ring in the center of the socket. And the ground on the metal rim on the outside.
Turn on the ignition and check for current flow. It’s important to note that your fuse will blow if your test light touches the outer metal rim. If you have a voltmeter, place the positive probe in the center and the ground on the outer rim. Turn on the ignition; You should get a reading of 12V, which means the outlet is working. This is where you hand your car over to the mechanic to have the wiring checked. If you’re determined to do it yourself, here’s how.
- Remove the dashboard trim to access the wiring. Once the wiring is accessible, make sure everything is secure before removing it.
- The metal contacts must be tight. If the wiring connectors are loose, the metal contacts can expand, causing a poor connection.
- If the metal contacts expand, use pliers to tighten them. If you find burn marks, the wiring must be replaced.
- Troubleshooting a Blown Cigarette Lighter Fuse
- In most cases, cigarette lighter problems are caused by a blown fuse. Replacing a fuse is fairly easy, provided you are careful and meticulous, as with any electrical component.
Otherwise, you risk damaging other electrical components, not to mention the fuses. If you’re wondering how to repair your car’s cigarette lighter fuse, here’s how to replace a blown fuse. Locate the Fuse Box
The fuse box can be located in one of three places: under the hood, in the trunk, or inside the passenger compartment.
It varies depending on the make and model of the car. Your car may also have more than one fuse box. You can find the location in your owner’s manual.
Under the hood: This is a black plastic box located near the windshield, either on the driver’s side or the far end of the passenger side. Passenger Compartment: Located on the driver’s side, near the trunk release button, and tucked under the dashboard.
Trunk: You can find it hidden in the trunk wall. A small latch on either the driver’s or passenger’s side allows you to open it.
In addition, most modern cars are equipped with spare fuses in one of these boxes. It may not be in the same box as the cigarette lighter fuse.
Removing the Blown Fuse
The fuse box contains various fuses that control different electrical functions. Make sure you identify the correct fuse. Some models may make it easier for you by labeling it as “Cig.” However, you can confirm this using the card in the lid or in your owner’s manual. Next, use a multimeter to determine if the fuse is working or blown. If you hear a beep, the fuse is working.
On the other hand, if it’s blown, you may not hear anything. Once you’ve confirmed this, you’ll need the smallest needle-nose pliers you can find to remove the fuse.
Most modern vehicles are equipped with a tool that looks and works like tweezers. If these aren’t available, you can use needle-nose pliers to remove the fuse.
Make sure you have a good grip on the pliers before removing the fuse.
Grip the ends of the fuse firmly, but not too hard, or you risk breaking the fuse, making it difficult to remove.
Your fuse should look like a SIM card, but it’s slightly larger. Therefore, be careful when removing it.
Examine the removed fuse. If you have a multimeter, you’ve already checked it. If you don’t have one, you can identify a blown fuse simply by looking at it. Cracked or broken wire: The body of a fuse contains a wire enclosed in a glass envelope. In the case of a blown fuse, the wire is broken or split.
Burnt marks: In the case of a blown fuse, you may see a charred wire or burn marks on the plastic casing. In both of the above cases, the fuse is no longer good and you should replace it with a new one. Replace with a new fuse
As mentioned earlier, the fuse box contains different fuses for various other functions of the car. Each fuse is assigned a different color and number.
Once you have identified the blown fuse, you can use it to find the appropriate replacement if one exists or purchase a new fuse.
Replacing the new fuse isn’t as difficult, but you must be careful and ensure proper alignment. Be sure to do this gently, as the replacement can break if you move it abruptly.
- Check your cigarette lighter
- With the above steps, your cigarette lighter should work. If it still doesn’t, it could be because:
- The replacement fuse has deteriorated after years of disuse.
The socket is damaged and needs to be replaced. In the first case, you can try a newly purchased fuse, but in the second, you should consult a mechanic. Related Questions
How much does it cost to repair a cigarette lighter in a car?
The cost of replacement depends on the problem. If it’s just the socket that’s the problem, it will cost between $50 and $100 to replace it.
However, if there’s a problem with the wiring, it could cost more. Why did my cigarette lighter break down?
There are several reasons why a cigarette lighter can fail. Any of the following can cause your fuse to blow:
Age
Heavy use
Humidity
Incompatible accessories
Can the cigarette lighter work if the car is off?
No, unless it’s directly connected to the battery, it only works when you turn on the car’s ignition.
This prevents energy waste and extends the life of your battery, as cars today are equipped with many electronic devices.
- Conclusion
- It’s not pleasant to find that your cigarette lighter isn’t working when you’re about to charge your phone. It’s fairly easy to repair as long as the plug doesn’t deteriorate or rust beyond use.
About 90% of these problems are due to a blown fuse. Start by checking your accessory, then clean any debris from the outlet. If it still doesn’t work, the fuse is probably blown.
