Nissan X-Trail T31: where is the cigarette lighter fuse and how to replace it

Cigarette lighter in Nissan X-Trail T31 (2007–2013 model year) is one of the most popular interior elements, especially if you actively use car gadgets: recorders, navigators, chargers or compressors. However, sooner or later, owners are faced with a problem: the cigarette lighter suddenly stops working, showing no signs of life. In 90% of cases it is to blame blown fuse, which protects the circuit from short circuit or overload.

Find this fuse in X-Trail T31 is not as simple as it might seem. Depending on the configuration and year of manufacture, its location may differ, and the information in the operating instructions is often blurred or absent altogether. In this article we will look at exact fuse box diagrams, we will indicate the numbers and ratings, and also tell you how to correctly diagnose and replace the fuse, avoiding typical mistakes. If you've already tried searching for it at random and haven't found it, don't worry: after reading this, you'll know exactly where to look.

Why does the cigarette lighter fuse blow in Nissan X-Trail T31

The cigarette lighter fuse is designed for a certain current strength (usually 15–20 A), and its burnout is not a breakdown, but defensive reaction for an emergency situation. Here are the main reasons why this happens:

• 🔌 Using powerful devices (compressors, inverters, refrigerators) with a current consumption higher than 15 A. For example, a car vacuum cleaner can consume up to 20 A, which will instantly burn the fuse.
• ⚡ Short circuit in the cigarette lighter or socket circuit. Damaged wires or oxidized contacts are often to blame.
• 🔄 Poor quality splitters (“tees”) with thin wires that heat up and cause current surges.
• 🔋 Old or worn fuse. Over time, the contacts oxidize, and even under normal load, spontaneous shutdown may occur.

If the fuse blows immediately after replacement, the problem lies not in it, but in the cigarette lighter circuit. In this case, diagnostics with a multimeter or visual inspection of the wiring for melting or damage to the insulation is required.

Where is the fuse box located in Nissan X-Trail T31

B Nissan X-Trail T31 fuses are distributed according to two main blocks: salon (inside the car) and engine compartment (in the engine compartment). The cigarette lighter fuse is located in salon block, but its exact location depends on the year of manufacture and configuration. Below we will analyze both options.

Cabin fuse box in X-Trail T31 is located to the left of the steering column, behind a plastic cover. To access it:

1. Open the driver's door and sit down to see under the steering wheel.
2. Find the plastic cover that says FUSE or fuse pictogram.
3. Carefully pry the cover with a flat head screwdriver or your fingers and remove it.

Under the cover you will see a fuse and relay box. On the back of the cover there is usually a diagram with the numbers and purpose of each fuse. However in some versions of T31 the circuit may be missing or outdated - in this case, refer to our data below.

What to do if there is no diagram on the lid?

If there is no diagram on the back of the fuse box cover, download the official manual for your model year (2007–2013) from the Nissan website or use the universal diagram from this article. You can also take a photo of the block and search for the assignment of fuses by numbers on the Internet, indicating the exact VIN of your car.

Number and rating of the cigarette lighter fuse in X-Trail T31

B Nissan X-Trail T31 The cigarette lighter fuse may have a different number depending on the year of manufacture and the market (European, Japanese or American version). Below is a table with the most common options:

Year of manufacture	Fuse number	Denomination (A)	Location in the block
2007–2010	#15 or #20	15 A	Top row, third or fourth from left
2011–2013	#12 or #18	20 A	Bottom row, second or third from right
Japanese versions (JDM)	#25	15 A	Center row, far right

If your fuse has a different number, check its assignment according to the diagram on the block cover or in service documentation. Please also note that in some trim levels X-Trail T31 The cigarette lighter and 12V socket in the trunk are protected different fuses. For example, in versions with a rear cigarette lighter it may be numbered #30 with a rating of 20 A.

Step-by-step instructions for replacing the fuse

Replacing the fuse in Nissan X-Trail T31 - a simple procedure, but requires care. Follow the instructions to avoid errors:

Turn off the ignition and make sure all electrical appliances are turned off

Prepare a new fuse of the same rating (15 A or 20 A)

Take tweezers or fine-nosed pliers

Prepare a flashlight to illuminate the fuse box -->

1. Turn off the power. Remove the key from the ignition and open the driver's door (this will discharge the circuits protected through the door switches).
2. Remove the fuse box cover. How to do this is described in the section above.
3. Locate the cigarette lighter fuse. Refer to the number from the table or diagram on the lid.
4. Remove the old fuse. Use tweezers (usually attached inside the block) or pliers. Do not pull on the wires under any circumstances!
5. Check integrity. Inspect the fuse against a light: if the metal thread inside is burned out, it needs to be replaced.
6. Install a new fuse. It should fit into the socket without effort. Do not insert a fuse of a different rating!
7. Check the operation of the cigarette lighter. Turn on the ignition and connect the device. If the fuse blows again, look for a problem in the circuit.

If after replacing the cigarette lighter still does not work, check:

• 🔌 Contacts in the fuse socket - they may be oxidized or bent.
• 🔧 The cigarette lighter socket itself - sometimes the central contact bends and does not touch the plug.
• 🔍 Wiring from the fuse box to the cigarette lighter for breaks.

Typical mistakes when replacing a fuse

Even something as simple as replacing a fuse can turn into problems if you make one of these mistakes:

⚠️ Attention! If you install a fuse and it immediately blows, do not rush to install the next one. Find the cause of the short circuit first, otherwise you risk burning the wiring or fuse box.

• 🔧 Using "bugs". Replacing a fuse with wire or foil is a grave mistake. This may lead to fire due to lack of circuit protection.
• 🔄 Installing a fuse of a different rating. For example, instead of 15 A they installed 30 A. Consequences: contact melting, failure of the cigarette lighter or even the fuse box.
• 🔌 Ignoring oxidized contacts. If the fuse socket or cigarette lighter contacts are covered with a green coating, they need to be cleaned, otherwise the new fuse will quickly fail.
• 🔍 Failure to check operation after replacement. Always test your cigarette lighter to before you close the fuse box. If it doesn't work, the problem may be with the socket or wiring.

Another common mistake is confusion with fuses. For example, in X-Trail T31 The cigarette lighter fuse is often confused with a fuse ACC (optional equipment) or CIGAR (cigarette lighter in some versions). Always check the diagram!

What to do if the fuse burns repeatedly

If a new fuse blows immediately after installation, this indicates serious problem in the circuit. Here is the diagnostic algorithm:

1. Disconnect all devices from the cigarette lighter and check the fuse. If it does not burn out, the problem is in one of the gadgets.
2. Inspect the cigarette lighter socket. Often the central contact shorts to the housing due to the ingress of metal objects or liquid.
3. Test the circuit with a multimeter. Put the device into resistance test mode and check for a short circuit between the positive contact of the socket and ground.
4. Check the wiring. Disconnect the cigarette lighter connector and inspect the wires for melting or damage to the insulation.

If you do not have experience working with automotive electricians, it is better to contact an auto electrician. In 30% of cases, repeated fuse blowing is associated with damage to the wiring under the interior trim, and without special tools it is difficult to find the problem.

⚠️ Attention! If, when checking the circuit, the multimeter shows a resistance close to zero (short circuit), do not turn on the ignition until the fault is eliminated! This can damage the fuse box or even the ECU.

FAQ: Frequently asked questions about the cigarette lighter fuse in the Nissan X-Trail T31

Is it possible to use a 20 A fuse instead of a 15 A fuse if the standard one often blows?

No, it's dangerous! The fuse is rated for the maximum current that the wiring can handle. Installing a fuse with a higher rating will lead to overheating of the wires and the risk of fire. If a 15-A fuse blows, look for the cause (short circuit or overload) rather than increasing the rating.

Where is the rear cigarette lighter fuse (in the trunk)?

In most versions X-Trail T31 The rear cigarette lighter is protected by a separate fuse numbered #30 (20 A) in the cabin unit. If not, check the fuse #18 (15 A) - sometimes it is responsible for both sockets.

How to check a fuse without a multimeter?

Visually: take out the fuse and look at the light - if the metal thread inside is broken, it has blown. You can also replace it with a known good one with the same rating (for example, from the size chain) and check the operation of the cigarette lighter.

What to do if the fuse is intact, but the cigarette lighter does not work?

Check:

• Contacts in the fuse socket (may be oxidized).
• The central contact in the cigarette lighter socket (often bends).
• Wiring from the fuse box to the cigarette lighter (possible breakage).
• The cigarette lighter socket itself (sometimes the internal contacts burn out).

If everything is in order, the problem may be in the relay or fuse box - diagnostics are required.

Is it possible to drive without a cigarette lighter fuse?

Technically yes, but it is highly discouraged. Without a fuse, the cigarette lighter circuit remains unprotected, and any short circuit can lead to melted wiring or even a fire. If a fuse blows frequently, find and fix the cause rather than operating the vehicle without protection.
