Situation when the cigarette lighter in a car stops working Nissan X-Trail generation T31, is encountered quite often by owners. This not only makes it impossible to charge your smartphone on the road, but may also indicate more serious problems with the crossover's electrical network. Often, drivers immediately suspect a breakdown of the socket itself or a complex wiring fault, wasting time and money on service visits.
In fact, in most cases the problem is solved by simply replacing consumables. Cigarette lighter fuse in the model Nissan X-Trail T31 designed to operate with high current, and when connecting powerful devices (for example, a compressor or a DVR with charging), it burns out first. Knowing the exact location of the block and the nominal value, you can restore functionality in a matter of minutes, without resorting to the help of specialists.
Diagnosis of the problem and preparation of tools
Before you go into the fuse box, you should make sure that the problem is in the protection and not in the device itself. Sometimes the cigarette lighter stops working due to oxidation of the contacts inside the socket or mechanical damage to the spiral heater. A simple test with another device, such as a phone charger, will help isolate the problem.
If the socket is visually intact and the power indicator on the connected gadget does not light up, proceed to searching for the fuse link. To work you will need a minimum set of tools. In modern cars, including Nissan X-Trail T31, there is often a special tool for removing fuses, which may be located directly in the block.
- 💡 Small Flashlight - The fuse box is often located in a dark area of the instrument panel.
- 💡 Tweezers or plastic clip - for safely removing elements without damaging the contacts.
- 💡 Multimeter or test lamp - to check the presence of voltage on the contacts after replacement.
It is important to understand that working with electrical equipment requires care. Although the voltage in the on-board network is only 12 volts, a short circuit can lead to a fire in the wiring or failure of the control units. Before starting any manipulations, make sure that the ignition key is in the OFF and all energy consumers are turned off.
⚠️ Warning: Never try to replace a fuse with a higher rated fuse, this may cause the wiring to melt and cause a fire the next time the current surges.
Location of fuse boxes in Nissan X-Trail T31
In the crossover Nissan X-Trail T31 There are two main fuse locations. The first block is located in the engine compartment, but it is primarily responsible for power units and engine control systems. The second, internal unit, is located directly inside the car and is the one we need.
The internal fuse box in this model is hidden under a plastic cover on the side panel of the dashboard on the driver's side. To get to it, you need to open the door and find a special plug that is secured with latches. It is located at the end of the instrument panel, closer to the doorway, at the level of the steering column.
Removing the cover does not require the use of screwdrivers if done correctly. It is necessary to carefully pry the edge of the plastic panel with your fingers or a plastic card so as not to scratch the casing. After removing the cover, you will see a diagram of the arrangement of elements printed on the back of the plastic, which greatly simplifies the search for the right fuse.
- 🚗 Driver's side: main access to the unit is through the end cap on the panel.
- 🔍 Diagram on the cap: always check the markings on the inside of the removed cap.
- 📦 Additional blocks: Sometimes the cigarette lighter can be protected by a separate relay in the engine compartment.
Determining the required fuse and its rating
On the diagram located on the inside of the unit cover, look for the symbol associated with the cigarette lighter. In most cases for Nissan X-Trail T31 This is a fuse with a marking FR-DE or ACC (Accessory). However, the markings may differ depending on the year of manufacture of the car and the configuration, so it is better to focus on the current strength.
The standard cigarette lighter fuse rating for this model is 20 Amps. It usually has a yellow body color, which is a visual indicator for quickly finding among other elements. If you see a fuse link with the number 20, but it does not match the diagram, carefully study the adjacent designations, as sometimes manufacturers change the location.
| Marking on the diagram | Purpose | Denomination (A) | Case color |
|---|---|---|---|
| FR-DE / CIG | Cigarette lighter and 12V socket | 20 | Yellow |
| RADIO | Audio system | 10 | Red |
| WIPER | Windshield wiper | 25 | White |
| FAN | Heater fan | 30 | Green |
Sometimes it happens that the fuse is visually intact, but the contact inside is broken. In this case, checking with a multimeter in continuity mode or using a test light will help. Touch the metal legs of the fuse with the probes: if the circuit is closed, the device is working properly.

Step-by-step instructions for replacing the fuse
The replacement process is extremely simple, but requires attention to detail. First, remove the old fuse using plastic tweezers, which are usually attached to the side of the block or included in the kit. If you don't have tweezers, you can use thin pliers, but be careful not to squeeze the plastic case too hard to avoid breaking it.
Insert a new fuse of the same rating into the empty slot where the old element was installed. Make sure that it is fully seated and the legs are pressed tightly against the contacts inside the connector. Do not try to insert the element by force if it does not fit - check the orientation of the legs and the integrity of the socket.
☑️ Replacement procedure
After installing the new element, close the unit cover and check the operation of the cigarette lighter. Insert any working consumer, such as a phone charger, and make sure the indicator lights up. If power appears, the problem is solved and you do not need to disassemble the dashboard.
⚠️ Attention: If the fuse blows immediately after installing a new one, stop use immediately and contact an auto electrician to look for a short circuit in the wiring.
What to do if there is no fuse available?
If you don’t have a 20 Amp fuse on hand, you can temporarily use an element with a lower rating (for example, 15 A), but it may burn out when connecting powerful consumers. It is strictly forbidden to install fuses of 30 A or higher - this is dangerous.
Why does a fuse blow: main reasons
Replacing the fuse is a temporary solution if the root cause of its failure has not been eliminated. In the car Nissan X-Trail T31 A common cause of burnout is the connection of non-standard equipment with high power consumption. For example, using a compressor to inflate tires or a powerful vacuum cleaner directly from the cigarette lighter will often result in exceeding the 20 Amp limit.
Another common problem is oxidation of the contacts inside the cigarette lighter socket. Due to moisture or dirt, the resistance at the contact point increases, which causes local heating and overload of the circuit. Visually, this may manifest itself in the form of soot or discoloration of the plastic around the nest.
- 🔋 Powerful devices: compressors, pumps and heaters exceed the permissible load.
- 💧 Moisture and dirt: liquid entering the socket causes a short circuit.
- 🔌 Poor contact: a loose socket creates an arc and overheats the circuit.
It is also worth paying attention to the quality of the fuse itself. Cheap Chinese analogues often cannot withstand the declared current and burn out even under normal load. Use only original parts or high-quality analogues of trusted brands, such as Bosch or Denso.
Before connecting powerful devices (compressor, pump), make sure that their power consumption does not exceed 240 Watts (20 Amperes × 12 Volts).
Diagnosis and repair of the cigarette lighter socket
If the problem comes back again and again after replacing the fuse, the socket itself is most likely faulty. In models Nissan X-Trail T31 a defect occurs when the central contact loses its elasticity or moves away from the body. This leads to poor contact and sparking when connecting plugs.
To diagnose, you need to remove the dashboard trim to gain access to the rear of the cigarette lighter connector. This is a more complex procedure that requires removing decorative trims and unscrewing fasteners. Be careful with plastic clips as they break easily if handled roughly.
In some cases, simply cleaning the contacts with alcohol and bending the central pin using a thin screwdriver helps. However, if the plastic of the socket is melted or cracked, the only correct solution is to completely replace the assembly. New cigarette lighter unit for Nissan X-Trail T31 Available at most auto parts stores.
Regularly checking the condition of the cigarette lighter socket and using quality fuses will extend the life of the vehicle's electrical system.
Relay testing and additional diagnostics
In some trim levels Nissan X-Trail T31 The cigarette lighter circuit is protected not only by a fuse, but also by a relay. If the fuse is intact, voltage is supplied to it, but the cigarette lighter does not work, the problem may be in the relay. The relay is located in the same block as the fuses and has a characteristic cubic appearance.
You can check the relay by replacing it with a known good one, for example, by taking a similar relay from another circuit (for example, from a fan or window regulator, if they are the same type). You can also check for a click from the relay when the ignition is turned on or when a load is connected.
If the relay is working properly, but the cigarette lighter does not work, there may be a problem in the wiring. A wire break can occur at a bend under the dashboard or as a result of mechanical damage when installing additional equipment. In such cases, professional diagnostics using a multimeter and a wiring diagram are required.
⚠️ Attention: When replacing a relay, pay attention to the contact markings and pinouts, since visually identical relays may have different internal circuits.
