Many owners of the legendary sedan Nissan Cefiro third generation (body A32) are faced with a situation where, when you try to turn on the charger or connect the DVR, the device simply does not respond. In 90% of cases the problem lies in burnout fuse, responsible for the power circuit of the 12 volt outlet. This is a classic fault for cars of this age and is often caused by the use of high-power adapters or a short circuit in the wiring.
Unlike modern cars, where diagnostics are carried out through the on-board computer, Nissan Cefiro A32 repair requires manual intervention and knowledge of the location of the blocks. You don't need to be a professional electrician to solve this problem, but you need to follow a strict sequence of steps and have a multimeter or spare protection parts on hand. Ignoring this malfunction can lead to more serious problems with the interior wiring.
Localization of fuse boxes in the cabin and under the hood
To begin the replacement, you need to accurately determine the location of the required element. By car Nissan Cefiro A32 There are two main protection units installed: interior and engine. Salon block The fuse box is located on the dashboard on the left side, on the driver's side, under a plastic cover. To access it, you need to open the door and pull a lever or simply unlatch the lid latches.
The second block is located in the engine compartment, but it is primarily responsible for power units and cooling systems, so when searching for the cigarette lighter fuse, it can be immediately excluded. Cigarette lighter circuit on the model A32 It is powered through the cabin unit. It is important to understand that the location of the contacts may vary slightly depending on the year of manufacture and configuration, so you cannot rely only on visual similarities.
If you don't see any markings on the lid, don't panic. On the back of the plastic block cover is usually marked diagram location of all elements. Study it carefully before you start pulling out parts. Look for a rosette symbol or "CIG" (Cigarette Lighter).
- 🔍 Inspect the block cover for a diagram indicating the contacts
- 🔧 Prepare tweezers or a special clamp that comes with the block
- 🔋 Make sure the vehicle ignition is turned off before starting work
⚠️ Attention: Do not try to remove the fuse with your bare hands if it is deep in the block. Use a plastic tool to avoid short circuiting between adjacent contacts or damaging the plastic of the housing.
Marking and ratings of power circuit protection
It is important to know the exact denomination fuse that needs to be replaced. On Nissan Cefiro A32 a 20 ampere (20A) element is responsible for powering the cigarette lighter and socket. This is the standard value for circuits supplying powerful current consumers. Installing an element with a lower rating (for example, 15A) will cause it to burn out even during normal operation of the recorder, and a higher rating (30A) will create a fire hazard in the event of a short circuit.
Color coding also plays a role in searches. Typically 20 amp fuses have yellow color. However, you should not focus only on color, since the block may contain elements from different years of replacement with different shades. Always check the number stamped on the plastic housing of the element. If the numbers are erased, use a multimeter to check.
Sometimes it happens that not only the main fuse blows, but also the accompanying circuit elements. In rare cases, due to a power surge, it may fail relay or the cigarette lighter housing itself. Therefore, when replacing, it is recommended to check the integrity of not only one element, but also adjacent circuits if they are connected to a 12-volt outlet.
| Component | Denomination (A) | Color | Designation on the diagram |
|---|---|---|---|
| Cigarette lighter main fuse | 20 | Yellow | CIG / ACC |
| Additional protection (socket) | 15 | Blue | ACC |
| Radio protection | 10 | Red | RADIO |
| Side light protection | 10 | Red | TAIL |
| Ignition system protection | 30 | Green | IGN |
⚠️ Attention: It is prohibited to replace a blown fuse with twisted wire, a coin or a bug. This can lead to a fire in the wiring and complete failure of the electronic engine control unit.

Step-by-step instructions for replacing a burnt-out element
The replacement process looks quite simple, but requires care. Open the block cover and find the required element according to the diagram. Using plastic tweezers (often attached to the block cover or lying next to the spare fuses), carefully grab fuse by the plastic part and pull it straight up vertically. Do not pull sharply so as not to break the contacts in the socket.
Visually inspect the elongated element. Inside it there is a thin metal jumper. If it is torn or melted, the fuse has blown. Replacement is done by installing a new element of the same rating in the same socket. Make sure it fits tightly and all the way. After installation, close the unit cover.
Now you need to check the functionality of the system. Insert a known-good device into the cigarette lighter or simply check for voltage at the outlet contacts. If the device works, then the problem has been solved. If not, then the cause may be deeper and a wiring diagnosis will be required.
☑️ Check before replacement
If the problem does not disappear after replacement, the cigarette lighter mechanism itself may be faulty. B Nissan Cefiro A32 Over time, the contacts inside the cartridge oxidize or burn, creating high resistance and heat. In this case, you will need complete replacement cigarette lighter socket.
- 🛠️ Use only new fuses with factory markings
- 🔦 Light the unit with a flashlight if it’s dark inside
- 🔌 Check if the wire going to the cigarette lighter is damaged
What should I do if the new fuse blows immediately?
If the new fuse blows instantly after installation, this indicates a short circuit in the circuit. In this case, do not try to install fuses of a higher rating. It is necessary to find the location of the short circuit, which may be caused by damaged wire insulation, a malfunction of the connected device, or an internal defect in the cigarette lighter itself. It is recommended to contact an auto electrician to check the circuit continuity.
Causes of frequent burnouts and wiring diagnostics
Why fuse Can it burn out again and again? The most common reason is the use of cheap or low-quality charging adapters that consume more current than the rated value. Modern smartphones and tablets can require significant power, especially when charging quickly, which puts a strain on a circuit designed for a standard cigarette lighter.
Another reason could be short circuit in the charger cable itself. If the insulation on the wire is damaged and the central contact of the device touches the metal case, a short circuit occurs. The problem may also be hidden in the oxidation of the contacts inside the cigarette lighter socket, which leads to heating and burnout of the jumper.
We should not exclude wear and tear on the car wiring. Over 20+ years of operation of the wires in the cabin Nissan Cefiro may break or fray, especially in bending areas. This creates a risk of a short to ground. For an accurate diagnosis, it is necessary to remove the tunnel lining and check the integrity postings to the cigarette lighter.
In some cases, the problem lies in the incorrect installation of additional equipment, such as video recorders or radar detectors. If you connected the device directly to the wiring, bypassing the standard circuit, or did it poorly, this can cause current surges.
- 🔋 Use only certified adapters with the required current
- 🔍 Regularly inspect the wires for damage to the insulation
- 🧹 Clean the contacts of the cigarette lighter socket from carbon deposits
Before connecting a new device, check its current consumption. If it exceeds 15-18 Amps, use a separate fused line connected directly to the battery rather than the stock cigarette lighter.
Features of repair and replacement of the cigarette lighter socket
If replacing the fuse does not help, the cartridge itself is most likely faulty. In the model A32 The cigarette lighter is attached through the decorative panel. To remove it, you need to carefully pry the panel with a plastic spatula and disconnect the connector. This requires some skill to avoid breaking the old interior's fragile plastic clips.
After removing the cartridge, carefully inspect its contacts. If the center pin sinks in or lacks elasticity, it will not make reliable contact with the plug of the device. In this case, repair or complete replacement node. Fortunately, cartridges for Nissan Cefiro They are a common part and easy to replace.
When installing a new socket, make sure the wiring is connected correctly. The center wire is positive, and the side contact is negative (ground). An incorrect connection can cause the fuse to instantly blow or damage the electronic device you connect.
How to check a cigarette lighter socket without a multimeter?
An easy way to check the socket is to use a test lamp or even a regular 12-volt light bulb. Connect it to the central contact and the body. If the lamp lights up brightly when the ignition is on, it means that power is being supplied and the problem is in the socket contacts. If the lamp does not light, you need to look for an open circuit or a faulty fuse.
⚠️ Attention: When working with the cigarette lighter, make sure that you do not touch the center contact and the metal body of the car at the same time, as this may cause sparks and burn your fingers.
A common cause of a blown fuse is the use of cheap Chinese chargers without overload protection, which create peak currents that exceed the circuit rating.
Prevention of malfunctions and selection of quality spare parts
To avoid repeated breakdowns, it is important to select spare parts responsibly. Cheap fuses from unknown sources are often of the wrong rating or poor contact, which can cause them to fail to fire on time or burn out for no reason. Choose trusted brands such as Bosch, Denso or original spare parts Nissan.
Regularly checking the condition of wiring and contacts also plays an important role. Periodically clean the cigarette lighter contacts from dust and carbon deposits using a cotton swab dipped in alcohol. This will ensure reliable contact and prevent heating. It is also recommended to check the reliability of the wires in the detachable connections.
If you plan to install powerful additional equipment, do not use the standard cigarette lighter. Run a separate line from the battery with an appropriate fuse. This will not only increase reliability, but will also remove the load from the standard interior wiring, which may not withstand high currents.
- ✅ Buy original or certified spare parts
- 🧼 Regularly clean the cigarette lighter contacts from dirt
- ⚡ Do not connect powerful devices to a standard outlet
Prevention is better than repair: regularly checking the condition of contacts and using high-quality adapters will extend the life of your car's electrical wiring for years.
Diagnosis of complex cases and search for a break
Sometimes the problem cannot be solved by simply replacing the fuse. In such cases, a full diagnostics circuit using a multimeter. First check for voltage at the fuse input. If there is voltage, check it at the output. If there is one at the input, but not at the output, the fuse has blown. If there is no voltage at the input, then the break is coming from the battery or relay.
It is also worth checking the integrity of the wires going to the cigarette lighter. They may rub against the body or other elements. Pay special attention to where the wire exits the fuse box and where it connects to the cigarette lighter. Problems often arise there due to vibration and frequent movement of wires.
If you do not have experience working with car electrical equipment, it is better to entrust complex diagnostics to professionals. Incorrect actions can lead to failure of electronic components or fire. However, knowing the location of the unit and the basic principles of operation, you can fix most simple faults yourself.
How to find the location of the short circuit?
To find the location of the short circuit, you can use the exclusion method. Disconnect devices connected to the outlet in series and check the operation of the circuit. If there is a short in the car wiring, use a multimeter in resistance measurement mode (ohmmeter). Disconnect the battery and measure the resistance between the positive wire and ground. Infinite resistance means there is no short circuit, zero or very low resistance means there is a short circuit.
