<em>Nissan Qashqai</em>cigarette lighter fuse: location, replacement and fault diagnosis

Cigarette lighter in Nissan Qashqai - one of the most popular electrical elements, especially if you actively use car gadgets: DVRs, navigators, chargers or compressors. However, sooner or later, many owners are faced with a situation where the cigarette lighter suddenly stops working. In 90% of cases the burnt out is to blame fuse - a small but critical detail that protects the circuit from short circuits and overloads.

In this article we will look at where the cigarette lighter fuse is located on Qashqai different generations (J10, J11, J12), how to check and replace it, and why it can burn out again and again. You will learn what fuse ratings are used in different modifications, how to avoid common mistakes when replacing, and what to do if the problem is not in the fuse. Let us dwell separately on hidden pitfalls, which even the official manuals are silent about - for example, why on some versions Qashqai The cigarette lighter is connected to the audio system fuse.

Where is the cigarette lighter fuse on Nissan Qashqai?

The location of the fuse depends on the generation and year of manufacture of the vehicle. B Qashqai he is always in interior fuse box, but its exact location and number may vary:

• 🔧 Qashqai J10 (2006–2013): The cigarette lighter fuse is marked as F37 (15A) or F38 (20A) depending on the configuration. The block is located to the left of the steering column, under a plastic cover.
• 🔧 Qashqai J11 (2013–2021): look for the fuse F40 (15A) or F41 (20A). The fuse box is hidden in a niche under the glove compartment on the driver's side.
• 🔧 Qashqai J12 (2021–present): Here the fuse can be designated as F27 (15A) and is located in the same block as on J11, but with a different circuit.

Important: on some versions Qashqai (especially with the system NissanConnect) the cigarette lighter can be powered through the same fuse as audio system or USB ports. If after replacing the fuse the radio stops working, do not be alarmed, this is normal.

Fuse box diagrams: where to look for the cigarette lighter?

To avoid guessing from the tea leaves, use the official fuse block diagrams for your version Qashqai. Below we provide current data for the most common modifications:

Generation	Fuse number	Denomination (A)	Location in the block	Linked circuits
J10 (2006–2013)	F37	15	Top row, 7th from left	Cigarette lighter, 12V socket in trunk
J10 (2006–2013)	F38	20	Top row, 8th from left	Cigarette lighter + audio system (on some trim levels)
J11 (2013–2021)	F40	15	Bottom row, 4th from left	Cigarette lighter, front 12V socket

⚠️ Attention: On Qashqai J11 with the system NissanConnect fuse F40 can be responsible simultaneously for the cigarette lighter and for powering the USB ports in the central tunnel. If after replacing the fuse both devices stop working, this is normal, just check the connection of the gadgets.

If there is no diagram on the fuse box cover (or it has been erased), download the official manual for your model from the website Nissan or use online services like FuseBoxInfo, which has interactive diagrams for most vehicles.

How to check the cigarette lighter fuse: step-by-step instructions

Before replacing the fuse, it must be checked. Here's how to do it right:

1. Turn off the ignition and remove the key from the lock. This is mandatory to avoid short circuit.
2. Find the fuse box (see diagrams above) and remove the cover. It is usually secured with latches.
3. Remove the fuse using plastic tweezers (included in the unit) or a small screwdriver. Do not use metal tools under any circumstances - you may damage the contacts!
4. Visually inspect the fuse. If the wire inside is burnt out (broken), it must be replaced.
5. Test the circuit with a multimeter (if in doubt). Set the resistance test mode and touch the fuse contacts with the probes. If the resistance tends to infinity, the fuse has blown.

⚠️ Attention: If the fuse appears intact, but the cigarette lighter does not work, the problem may be oxidized contacts block or in the cigarette lighter socket itself. Try cleaning the contacts with alcohol or a special electronics fluid.

If you are not confident in your abilities, you can use non-contact voltage tester. Bring it to the cigarette lighter socket with the ignition on - if the indicator does not light, the problem is definitely in the fuse or wiring.

How to replace the cigarette lighter fuse: step-by-step algorithm

Replacing a fuse is a simple operation, but there are some nuances here too. Follow the instructions to avoid mistakes:

1. Buy the correct fuse rating. For Qashqai this is usually 15A (yellow) or 20A (blue). Never install a fuse with a higher rating - this may cause a fire!
2. Turn off the power: Remove the key from the ignition and open the driver's door (this will discharge the capacitors in the system).
3. Remove the old fuse tweezers. If it gets stuck, don’t pull it - gently rock it from side to side.
4. Install a new fuse until it clicks. Make sure it stands up straight and without distortion.
5. Check the operation of the cigarette lighter: Insert the charger or tester. If the fuse blows again, the problem is a short circuit!

⚠️ Attention: If, after replacement, the fuse burns out immediately when connecting a load (for example, a compressor), do not rush to install the next one. This is a sign short circuit in the cigarette lighter circuit or in a connected device. Check:

• 🔌 The cigarette lighter socket itself for the presence of foreign objects (coins, paper clips).
• 🔌 Charger plug - the wires may be exposed.
• 🔌 Wiring from the fuse box to the cigarette lighter (if you have experience with a multimeter).

Why the cigarette lighter fuse blows: top 5 reasons

If the fuse blows regularly, you need to look for the cause. Here are the most common culprits:

• ⚡ Short circuit in the cigarette lighter socket. Often the culprit is coins, paper clips, or other metal objects that get caught inside. Contacts can also close due to corrosion.
• ⚡ Faulty charger or gadget. Cheap Chinese chargers often cause overload. Test the device on another machine.
• ⚡ Circuit overload. If you connect powerful devices (for example, a refrigerator or inverter) to the cigarette lighter, the current may exceed 15–20A. In this case, you need to use a splitter with a separate fuse.
• ⚡ Oxidation of contacts. Over time, the contacts in the fuse box or cigarette lighter socket oxidize, causing increased resistance and heat.
• ⚡ Wiring problems. Damage to the insulation of the wires leading from the fuse box to the cigarette lighter can cause a short circuit.

If the fuse burns out immediately after replacement, do not take risks - contact an auto electrician. Finding a short circuit on your own without experience can lead to damage to the on-board electronics.

What to do if the fuse burns out immediately?

If the new fuse blows instantly when the ignition is turned on, this is a sign of a direct short circuit. In this case:

1. Disconnect the negative terminal of the battery.

2. Remove the cigarette lighter fuse.

3. Using a multimeter in “continuity” mode, check the circuit between the cigarette lighter socket contacts and the vehicle ground. If there is a short circuit, the device will beep.

4. If a short circuit is confirmed, do not turn on the fuse until the problem is resolved!

What to do if replacing the fuse did not help?

If the cigarette lighter still does not work after replacing the fuse, the problem may lie elsewhere. Here's what to check next:

• 🔍 Cigarette lighter socket. Often the contacts inside the socket become oxidized or become bent. Try gently bending them with a thin screwdriver or cleaning them with sandpaper.
• 🔍 Wiring. Use a multimeter to check the voltage at the socket contacts with the ignition on. If there is no voltage, the problem is a broken wire or in the fuse box.
• 🔍 Cigarette lighter relay. On some versions Qashqai (especially J10) the cigarette lighter is controlled via a relay. It may be in the same block as the fuses.
• 🔍 Body Control Module (BCM). In rare cases, the problem may be related to the electronics. This can only be diagnosed with a scanner.

If you are not confident in your skills, it is better to contact the service. For example, replacing the cigarette lighter socket with Qashqai J11 requires disassembling the center console, which without experience can lead to damage to the plastic clips.

Recommendations for using the cigarette lighter Nissan Qashqai

To avoid problems with the fuse and cigarette lighter, follow these simple rules:

• 🚗 Do not connect devices with more power to the cigarette lighter. 180 W (for 15A) or 240 W (for 20A). For more powerful gadgets, use a power strip with a separate fuse.
• 🚗 Regularly clean the cigarette lighter socket of debris. It is enough to blow it out with compressed air once every six months.
• 🚗 Do not use cheap chargers without short circuit protection. It's better to overpay for branded accessories.
• 🚗 If the cigarette lighter heats up during operation, this is a sign of poor contact. Check the socket and fuse.

If you frequently use your cigarette lighter to connect multiple devices, consider installing an additional outlet 12V with separate fuse. This will relieve the standard circuit and reduce the risk of burnout.

FAQ: Frequently asked questions about the cigarette lighter fuse Nissan Qashqai

Is it possible to install a fuse of a higher rating, for example, 25A instead of 15A?

No, this is extremely dangerous! The fuse is rated for the maximum current that the wiring can handle. If you put a fuse on 25A, if overloaded, the wires may melt, which will lead to a fire. Always use the fuse of the rating specified in the manual.

The cigarette lighter works, but the voltage sags when a load is connected. What's the matter?

This is a sign of poor contact in the circuit. Check:

• The condition of the contacts in the cigarette lighter socket (they may have oxidized).
• The quality of the connection in the fuse box.
• Wiring from the block to the cigarette lighter (there may be a break or corrosion).

It could also be due to a weak battery or problems with the generator.

After replacing the fuse, the radio stopped working. This is fine?

Yes, on some versions Qashqai J11 The cigarette lighter and audio system are powered from one fuse (F40). If the radio does not turn on, check to see if the fuse has blown again, or reset the audio system (remove the fuse for 10 seconds and put it back in).

Is it possible to change the cigarette lighter socket yourself?

Theoretically yes, but Qashqai To do this, you need to disassemble the center console, which requires skill. If you do not have experience, it is better to contact the service - the cost of work usually does not exceed 1–1.5 thousand rubles. The nest itself costs about 500–800 rubles.

How to check if the cigarette lighter wiring is short?

Disconnect the negative terminal of the battery, remove the cigarette lighter fuse and test the circuit with a multimeter in the “test” mode:

1. Connect one probe to the positive terminal of the cigarette lighter socket.
2. The second dipstick is for the vehicle's weight.

If the device beeps, there is a short circuit in the circuit. If it is silent, the wiring is fine.
