To troubleshoot the problem yourself, you need to know exactly the location of the fuse box and be able to identify the required element. Unlike newer models, Nissan Qashqai J10 The protection distribution scheme differs slightly depending on the year of manufacture and equipment level, so it is important to carefully study the markings.
Correct diagnosis will save you time and money, since replacing a fuse takes only a few minutes with a minimum set of tools. Below we will discuss in detail where exactly to look for the required element, how to check it correctly and what to do if the new fuse fails again immediately after installation.
Location of fuse boxes in the passenger compartment
The main unit responsible for the operation of the cigarette lighter in Nissan Qashqai J10, is located inside the car, and not under the hood. You will need to open the driver's door and carefully inspect the side dashboard located to the left of the steering column.
In this area you will see a plastic decorative cover with the inscription FASS or fuse symbol. It is here that the protection elements for the internal electronics are collected: power windows, radio, side lights and 12-volt sockets. By opening the lid, you will have access to a diagram that shows the values of all the elements.
Sometimes access may be difficult if the vehicle is equipped with an additional audio system or other accessories. In this case, carefully unclip the cover latches without using excessive force to avoid breaking the plastic case.
Cigarette Lighter Fuse Identification
Once you have found the block, you will need to match the positions of the fuses to the included diagram. In most modifications Nissan Qashqai of the first generation, a fuse with a rating of 20A (Amperes) is responsible for powering the cigarette lighter.
It is usually yellow in color, which is the standard color coding for 20 amp devices. In the diagram it can be designated as CIG (Cigarette Lighter) or have a rosette icon. However, it is worth considering that in some early versions produced in 2007-2008, the scheme may have differed slightly.
It is important not to confuse this element with the audio system power fuse, as they are often located nearby. If you are unsure of the exact location, use a test light or multimeter to check for voltage at the pins.
Tools and replacement procedure
You don't need a complicated tool to get the job done. Usually there is a special tweezer in the fuse box cover that is convenient for removing elements. If you don't have one, you can use a small bunch of pliers with insulated handles.
Before starting the procedure, make sure that the car's ignition is turned off. Pull out the suspicious fuse and carefully inspect its plastic housing. A burnt element will have a torn metal bridge inside clear plastic.
Install a new fuse of the same rating as the old one. Never try to replace a burnt-out element with a fuse with a higher rating, as this may lead to melting of the wiring and even a fire.

- Problems with glasses
- Light not working
- Media failures
Additional block under the hood
Although the main unit is located in the cabin, some electrical circuits associated with powering the cigarette lighter may be duplicated or protected in the engine compartment. This block is often called IPDM (Integrated power distribution unit).
It is located in the engine compartment, closer to the windshield on the passenger or driver side (depending on the market). This block contains more powerful relays and fuses responsible for the starter, generator and other highly loaded components.
If the fuse in the passenger compartment is intact, but the cigarette lighter does not work, it makes sense to check the main relays in the engine compartment. Sometimes the problem lies not in the fuse link, but in a stuck or oxidized relay.
☑️ Checking the cigarette lighter circuit
Common causes of burnout
Constantly blowing fuses indicates a serious problem in the circuit. The most common reason is the use of high-power inverters or chargers that draw current above the permissible limit of 20 amps.
A short circuit in the wiring may also be the cause. This often happens if metal objects get into the cigarette lighter socket, or if the wiring is damaged at a bend near the gear shift lever.
The poor quality of the fuse itself also plays a role. Cheap analogues may not withstand even standard loads if their manufacturing tolerances are violated. Always use original spare parts or trusted brands such as Cooper Bussmann or Littelfuse.
If the new fuse burns instantly when the ignition is turned on, do not continue to attempt replacement - most likely there is a short circuit in the circuit that requires a specialist to diagnose the wiring.
Diagnostics with a multimeter
If the fuse visually looks intact, but the cigarette lighter does not work, use a multimeter. Switch the device to resistance measurement mode (ohmmeter) or continuity testing.
Apply test leads to both fuse contacts. If the device shows zero resistance or makes a sound signal, the element is working. If the resistance is infinitely high, there is a rupture inside and the element requires replacement.
You can also check for voltage directly at the cigarette lighter socket. In voltmeter mode, attach the black probe to ground (body), and the red probe to the central contact of the socket. Normal voltage should be about 12-14 volts.
What to do if the fuse burns out immediately?
If replacing the fuse does not work and the new element burns out when turned on, this is a sure sign of a short circuit. Check the wiring for kinks or damaged insulation. Often the problem occurs where the wire passes through the metal body if there is no protective rubber bushing.
Features of different years of production
Owners Nissan Qashqai J10 2007-2010 may encounter peculiarities in the arrangement of elements. In earlier versions, the scheme could have been simpler, without division into subgroups.
Since 2011, before restyling, the manufacturer made some changes to the electrical circuit. Warning notices and markings on the unit cover may have been translated into other languages or have changed font.
Incorrectly removing the wrong element can lead to transmission malfunctions.
Correct diagnosis of a fuse requires not only a visual inspection, but also checking the integrity of the circuit with a multimeter, since the internal spiral can be damaged without being noticed by the eye.
Table of main interior fuses
For ease of orientation in the interior fuse box Nissan Qashqai J10 We have compiled a summary table with the most important elements that are often of interest to owners.
| Name / Marking | Denomination | Color | Purpose |
|---|---|---|---|
| CIG | 20A | Yellow | Cigarette lighter and 12V socket |
| RADIO | 10A | Red | Radio and multimedia system |
| ECU-IG | 10A | Red | Engine control unit (part of circuits) |
| DOOR | 15A | Blue | Electric door locks |
| MIRROR | 7.5A | Burgundy | Adjusting the rear view mirrors |
Why is it important to keep the par value?
Installing a fuse with a higher rating (for example, 30A instead of 20A) deprives the circuit of protection. If there is a short circuit, the wiring may overheat and melt before the protection operates, resulting in a fire.
Critical points during maintenance
Always follow safety precautions when working with car electrical systems. Even when the ignition is turned off, some circuits may be energized, which is dangerous for electronic components.
Pay special attention to the contacts in the block. Over time, they can oxidize, causing poor contact and heating. If you see deposits on the contacts, carefully clean them with an eraser or a special contact liquid.
Never leave the fuse box open for long periods of time. Humidity and dust can cause corrosion and new problems. Make sure the cover is securely latched and the latches are not damaged.
⚠️ Attention: If you find signs of melted plastic around the fuse socket, simply replacing the element will not solve the problem. It is necessary to replace the fuse box itself or repair the damaged connector, since the contact will have high resistance and heat up.
FAQ: Frequently asked questions
Why did the cigarette lighter stop working after installing the navigator?
Most likely, there was a short circuit or overload of the circuit when connecting the navigator. Check the fuse CIG for burnout. If it is intact, check whether you have connected the new device directly to the positive terminal without a fuse.
Can I use a 15A fuse instead of a 20A fuse for the cigarette lighter?
This is technically possible, but not recommended. When using powerful devices (for example, a compressor or vacuum cleaner), a 15A fuse will blow too often. This is a temporary solution that does not eliminate the cause, but protects the circuit from overload.
Where can I find the fuse diagram if the cover is lost?
The diagram can be found in the vehicle's owner's manual in the "Maintenance" section. Also, current diagrams are often available on specialized owner forums Nissan Qashqai or in technical manuals on the Internet.
What to do if the fuse is intact, but there is no voltage at the outlet?
Check the relay in the engine compartment. It is also possible that the wire in the harness leading from the fuse box to the outlet may be broken. In this case, you will need to diagnose the wiring with a multimeter along the entire length of the cable.
⚠️ Attention: On Nissan Qashqai J10 vehicles with an automatic transmission, disabling the cigarette lighter fuse may affect the operation of the automatic transmission selector lock system when starting the engine.
