Nissan Qashqai J10 (2007–2013) is one of the most popular crossovers in Russia, but even such a reliable car eventually develops electrical problems. Most often, the culprit is blown fuses or faulty relays in the cabin unit. If your headlights, power windows, cigarette lighter or radio stop working, the first thing you should check is this particular unit.
Unlike the engine compartment block, the interior mounting block Qashqai J10 hidden from view and not always obvious to a beginner. In this article you will find exact diagrams with a decoding of each fuse and relay, step-by-step replacement instructions, as well as tips on how to avoid common mistakes. We'll figure out which circuits each element protects, how to correctly diagnose a fault, and what to do if a fuse blows over and over again.
Where is the fuse box in the passenger compartment? Nissan Qashqai J10?
Interior fuse and relay box Qashqai J10 located to the left of the steering column, behind the plastic cover. To access it:
- Sit in the driver's seat and turn the steering wheel to the left all the way.
- Find the plastic cover that says «FUSE» (or without it - depends on the configuration).
- Press the latch at the top of the cover and pull it towards you.
The cover will open, revealing the fuse and relay box. In some versions Qashqai J10 (for example, with right-hand drive) the location may differ slightly, but the principle of access remains the same. If the lid does not budge, do not use force - check for additional latches on the sides.

Fuse box diagram: assignment explanation
In the salon block Nissan Qashqai J10 fuses and relays are installed that are responsible for the main electrical circuits of the car. Below is a table with a breakdown of the most important elements (numbers may vary slightly depending on the year of manufacture and configuration).
| Number | Rating (A) | Purpose | Symptoms of a problem |
|---|---|---|---|
| 1 | 10 | Audio system, navigation | The radio does not work, the navigation screen does not turn on |
| 5 | 15 | Cigarette lighter, 12V socket | Cigarette lighter does not work, devices do not charge |
| 10 | 7.5 | Body Control Module (BCM) | Power windows, central locking and light alarms do not work |
| 15 | 10 | Low beam (right headlight) | The right headlight does not light up in low beam mode |
| 20 | 10 | High beam (left headlight) | Doesn't switch to high beam on left side |
Important: Before replacing a fuse, always check for a short circuit. If the new fuse immediately blows, the problem lies not in it, but in the wiring or consumer (for example, in the radio or window motor).
Full fuse diagram for all trim levels
In the block Qashqai J10 5–30 A fuses are installed. A complete diagram for your configuration can be found in the instruction manual (section “Electrical equipment”). If there is no manual, download it in PDF from the official Nissan website or on owner forums (for example, Qashqai Club). Please note: in vehicles with diesel engine 1.5 dCi and gasoline 2.0 MR20DE Schemes may vary!
How to check and replace a fuse: step-by-step instructions
Replacing the fuse in Nissan Qashqai J10 - a simple procedure, but requiring accuracy. Here's what you'll need:
- 🔧 Tweezers (usually included with the car, in the fuse box).
- 🔍 Flashlight (for inspecting contacts).
- 📋 New fuse same denomination (never install a fuse with a high value!).
- 🔌 Multimeter (optional, for checking the circuit).
Now let's start replacing:
- Turn off the ignition and make sure that all electrical consumers (headlights, radio) are turned off.
- Remove the fuse box cover (as described above).
- Find the faulty fuse. It can be determined visually (a burnt-out thread inside) or using a multimeter in continuity mode.
- Use tweezers to remove the old fuse and install the new one. Make sure it fits snugly into the socket.
- Close the unit cover and check the operation of the circuit.

Critical error: never replace the fuse with a "bug" (wire or foil). This may cause the wiring to catch fire!
Typical problems and their solutions
If the fuse is in Qashqai J10 burns out again, this is a signal of a more serious malfunction. Let's look at the most common cases:
- 🔌 Cigarette lighter: Most often, fuse No. 5 (15 A) blows due to the use of powerful devices (for example, car vacuum cleaners or compressors). Solution: Use a fused power strip or connect devices directly to the battery.
- 🎵 Audio system: Fuse No. 1 (10 A) may blow due to a short circuit in the radio or speaker wires. Check the integrity of the insulation and contacts.
- 🚗 Window lifters: If fuse No. 10 (7.5 A) is blown, the problem may be in the window motor or control unit. Try turning off the motor and checking the circuit without load.
If you cannot find the cause, contact an auto electrician. In some cases (such as a short in the wiring harness), a full diagnosis using the wiring diagram may be required.
Before replacing the fuse, take a photo of its location with your phone. This will help you avoid confusing the values when installing a new one.
Relay in the cabin unit: purpose and verification
In the salon block Nissan Qashqai J10 relays are also installed that are responsible for turning on powerful consumers. For example:
- 💡 Low beam relay: Controls the operation of headlights. If the relay fails, the headlights may flicker or not turn on at all.
- 🔊 Horn relay: If there is a malfunction, the signal becomes quieter or disappears.
- 🚪 Central locking relay: If the doors do not lock, check this relay and fuse #10.
To check the relay, remove it from the block and inspect the contacts for oxidation or burning. You can also replace a suspicious relay with a known good one (for example, from the same circuit). If the problem disappears, the relay is faulty.
⚠️ Attention: Not all relays in the block are interchangeable! For example, the low beam relay and the cooling fan relay have different markings. Always check the labels on the case.
Frequently asked questions from owners Nissan Qashqai J10
Owners Qashqai J10 often encounter the same problems related to the fuse box. Here are the answers to the most popular ones:
Why does the cigarette lighter still not work after replacing the fuse?
Possible reasons:
- The fuse in the circuit has blown
ACC(check fuse #3). - The contacts in the cigarette lighter socket have oxidized (clean them with alcohol).
- The problem is in the cigarette lighter itself - check it with a multimeter.
Is it possible to use a fuse with a higher rating if the standard one constantly blows?
No! Increasing the rating will lead to overheating of the wiring and the risk of fire. Instead, find the cause of the short circuit (most often it is damaged insulation or a faulty consumer).
Where can I find a fuse diagram for my configuration?
Schemes for a specific modification Qashqai J10 can be found:
- In the operating manual (section "Electrical equipment").
- On the cover of the fuse box (sometimes there is a sticker there with a decoding).
- On specialized forums (for example, Qashqai Forum).
If the fuse blows repeatedly, do not replace it - look for the cause of the short circuit!
When to contact the service?
Not all problems are electrical. Nissan Qashqai J10 you can decide on your own. Contact a specialist if:
- 🔥 The fuse blows immediately after replacement (this indicates a short circuit in the circuit).
- 🔌 Several circuits do not work at the same time (perhaps the problem is in the control unit or wiring harness).
- 🛠️ You cannot find the faulty relay or fuse (scanner diagnostics required).
The cost of diagnostics of electrical equipment in the service starts from 1,500 rubles, but this is cheaper than risking the safety of the car. In Moscow and St. Petersburg, we recommend contacting official dealerships Nissan or proven auto electricians with experience working with Qashqai J10.
⚠️ Attention: If after replacing a fuse or relay there is a burning smell, immediately disconnect the battery and contact service! This is a sign of melted wiring.
