Why Doesn’t the 12v Socket in My Car Work?

Should I be able to connect a 12v product using a cigarette lighter?

All cigarette lighter sockets are also 12V sockets. This means you should be able to connect a cigarette lighter inverter, cell charger, or other 12V DC accessory to any car’s cigarette lighter socket and it should work properly.

If your cigarette lighter has stopped working or appears to be malfunctioning, several issues can arise:

  • Obstacles in the socket – This is most common when the cigarette lighter socket is installed vertically on the center console. Because this orientation makes it easy for small objects to fall into the socket. Non-conductive obstacles prevent the charger from coming in contact, and conductive objects such as coins can burn the circuit.
  • Cigarette lighter socket burned out – It means that the outlet is not getting any power at all. The fuse may be blown or there may be another problem with the wiring.
  • The charger itself is bad – The charger is bad and should be ruled out. The charger’s electronics may be defective, the plug that fits the device may be defective, or the spring on the plug that fits into the cigarette lighter socket may be worn out.

How to fix a cigarette lighter that doesn’t work

To get the cigarette lighter working again, you need to identify and rule out possible problems. Some of these steps are very simple and require no special equipment, but you will need a test light or voltmeter to fully perform this type of diagnosis.

Here are the basic steps to follow when your cigarette lighter has stopped working:

Check the cigarette lighter socket for foreign objects. If you find something like food, small toys, or coins in the cigarette lighter socket, carefully remove it. Do not insert metal objects such as screwdrivers or tweezers into the socket.

Check power and grounding at the outlet – For this you will need a test lamp or voltmeter. If you have these tools and know how to use them, check the power at the center pin of the cigarette lighter socket and ground inside the barrel. If power cannot be found, check the fuse. If you cannot find power or ground, check the connection to the cigarette lighter socket.

Try connecting another device. If you don’t have a test light or voltmeter, find another 12V charger or device. It’s important to make sure your device actually works, so you can borrow something a friend or family member uses on a regular basis. If it’s plugged in and it doesn’t work, the outlet may not be getting power.

Try plugging in a cigar lighter. If you still have the cigarette lighter that came with your car, plug it in and press hard to activate it. If it pops out and the coil is red hot, then the outlet is OK. If there is no heating, there will be no power to the outlet.

Try plugging the charger into a different outlet. If your vehicle has additional accessory sockets, make sure the charger works on those sockets. If not, try using the charger in another vehicle. If it does not work with other outlets, the charger may be defective.

Check for foreign objects

If nothing works when plugged into a 12V accessory outlet, the first thing to do is check the outlet for obstructions. The easiest way is to pick up a flashlight and physically look at the outlet.

wire of life.

One of the most common causes of cigarette lighter and 12V accessory socket problems is accidentally dropping a coin into the socket. This may short out the outlet and blow the fuse, but it may also stop the accessory plug from contacting.

Dropping a non-metallic object into a cigarette lighter or 12V accessory socket will not short-circuit or blow the fuse. However, foreign objects can prevent the accessory connector from making electrical contact. This means that the circuit is still hot when it gets inside to remove the command. Therefore, be careful not to accidentally short circuit.

check electricity

If the outlet is not obstructed, you can proceed in one of three ways. The easiest way is to connect a cigarette lighter if you have one. If the lighter gets hot and pops out, the outlet has power. You can also use a test lamp to check power or inspect the fuse panel to see if the cigarette lighter fuse has blown.

You cannot test with a cigarette lighter if the 12V outlet is actually an accessory outlet and not a cigarette lighter outlet. In this case, you need to use a test lamp or multimeter to actually check the power supply.

If the fuse hasn’t blown and the outlet has power, there may be a problem with the outlet or accessory plug you are trying to use. Cigarette lighters and 12V accessory sockets are designed with slightly looser tolerances, and the slack will be filled with spring loaded contacts, but without the contacts the accessory will not be powered.

Dealing with a blown cigarette lighter fuse

In many cases the cigarette lighter fuse has blown and this can be caused by a variety of problems. If you find a coin in the socket, you’re probably done. If you haven’t done this, you may have a paragraph or link somewhere else. An example would be a cigarette lighter inverter that simply draws more current than the circuit can handle.

Cigarette lighter circuits are often fused at 10 or 15 A, which is usually not much. So unless your cigarette lighter inverter is specifically designed to keep your current requirements below this level, connecting multiple electronics could theoretically blow the fuse and cause the inverter to fail.

The easiest way to proceed from there is to replace the cigarette lighter or 12v accessory socket fuse and see what happens. If it burns out immediately, there is a short circuit somewhere in the circuit. If you plug in a cigarette lighter and the fuse blows, it’s probably a problem. At first everything is fine, but if the fuse blows when connecting the inverter, the inverter may be the cause.

In any case, the inherent limitations of cigarette lighter inverters mean that you may be better off with another inverter wired directly to the battery or fuse panel. For more information on how to do this, see our article on Estimating Inverter Requirements.

Shouldn’t I be able to use my cigarette lighter to plug in 12v stuff?

All cigarette lighter sockets are also 12v sockets, which means that you should be able to plug in a cigarette lighter inverter, cell charger, or any other 12v DC accessory into any cigarette lighter socket, in any vehicle, and have it work just fine.
