Power supply system of a modern car Nissan Almera generation G15 is a complex assembly where each circuit is protected by a separate element. If the power windows suddenly stop working, the heater fan does not turn on, or the light in the cabin goes out, the reason most often lies in a blown fuse. This is a standard protective reaction of electronics to a power surge or short circuit.
Many owners Nissan Almera are lost when trying to find the required security element, since the circuit may seem confusing without the proper knowledge. In this material, we will analyze in detail the location of the fuse box in the cabin, decipher all the symbols on the cover and in the technical documentation, and also learn how to correctly diagnose a malfunction without contacting a dealer.
Understanding how your vehicle's electrical system works can save you time and money. Instead of calling a tow truck or visiting a service center, you can fix a simple breakdown yourself in a few minutes, using a minimal set of tools and knowledge of where the critical components are located.
Location of the fuse box inside the car
Main fuse box in the body Nissan Almera The G15 is located in the driver's area, allowing quick access when needed. It is hidden behind a decorative trim at the end of the instrument panel, on the driver's door side. To get to it, you will need to open the door and carefully examine the side of the dashboard.
The cover covers the fuse box and has a special slot for easy removal. It is secured with plastic latches that can be easily released when pressed. Be careful not to damage the fragile plastic when removing it, as replacing the panel may require new fasteners.
- 🔍 Open the driver's door and inspect the end of the instrument panel.
- 🔧 Find a rectangular cover with an inscription or diagram on it.
- 🚗 Carefully press the latches and remove the decorative trim.
Inside you will see a plastic case in which security elements of various colors and sizes are tightly placed. Next to the block there is often tweezers or a special clamp designed to safely remove blown fuses. If the tool is not at hand, you can use ordinary tweezers with narrow jaws, but you need to act extremely carefully.
⚠️ Attention: Before removing any protection element, be sure to make sure that the car’s ignition is turned off and all energy consumers are de-energized.
Reading and decoding symbols on the diagram
On the inside of the fuse box cover there is a diagram that serves as a navigator for the owner. Each cell is numbered and equipped with a pictogram indicating the consumer being protected. Without understanding this symbolism, troubleshooting turns into a long and futile process of searching.
The digital values on the elements indicate the current in amperes for which the fuse is designed. The color of the case also matters: yellow - 20A, red - 10A, blue - 15A, green - 30A and so on. Matching the color and denomination simplifies the visual identification of the desired element, even without using a diagram.
- 🔌
F1— a unit responsible for powering the radio and cigarette lighter. - 💡
F2— control circuit for interior interior lighting. - 🚗
F3- windshield wiper motor.
Sometimes the diagram uses abbreviations in English, which may not be obvious to an untrained user. For example, the abbreviation IG1 means the primary circuit ignition circuit, and ECU — engine control unit. Knowing these abbreviations helps to quickly localize the problem in a specific control system unit.

Diagnosis of faulty fuses
There are two main ways to determine a blown fuse: visually or using a multimeter. Visual inspection is suitable for transparent enclosures where it is easy to see the torn metal bridge inside. If the body is black or the jumper is not visible, a more precise tool will be needed.
- 👀 Inspect the metal strip inside the transparent case for a tear.
- 📏 Use a multimeter in continuity check mode for an accurate diagnosis.
- 💡 Insert the probes into the contact plates from above and check for signal presence.
When using a multimeter, one probe is applied to the top contact of the fuse, and the other to the second. If the device shows zero resistance or makes a sound signal, the element is working. No signal or infinite resistance on the display indicates that the fuse has blown and requires immediate replacement.
Why might a fuse burn out immediately after replacement?
Most often, this indicates a short circuit in the wiring or a malfunction of the consumer itself. Simply replacing an element without finding the cause will lead to re-burnout.
It is important not only to replace the burnt out element, but also to understand the cause of the overload. If the new fuse blows instantly, there is a critical fault in the circuit that needs to be repaired by a qualified electrician. Ignoring this factor can lead to wiring fires or failure of expensive electronic components.
Substitution rules and choosing the appropriate denomination
Replacing a blown fuse is a procedure that requires attention to detail. Under no circumstances should overrated elements be used, as this will deprive the circuit of protection and create a risk of fire. Use only fuses of the same color and amperage as specified by the manufacturer.
- ✅ Remove the faulty element using tweezers or forceps.
- 🔢 Make sure that the value of the new item exactly matches the old one.
- 🛠️ Insert the new fuse until it clicks into the corresponding cell.
If you don't have a suitable spare element on hand, you can temporarily take a fuse from a circuit that is not critical for movement, for example, from the cigarette lighter or radio circuit. This will allow you to get to the nearest auto parts store. However, after the first opportunity, it is necessary to restore the standard configuration of the electrical network.
☑️ Instructions for safe replacement
The quality of the spare parts used plays a decisive role in the reliability of the electronics. Cheap analogues may not be able to withstand peak loads and burn out prematurely, or, conversely, fail to operate in the event of a short circuit. It is best to use original components Nissan or trusted brands specializing in automotive electronics.
⚠️ Attention: It is prohibited to use wire, foil or matches as jumpers. This is a gross violation of safety regulations that can lead to melting of the wiring.
Scheme of main consumers and their protection
In the interior fuse box Nissan Almera G15 contains elements responsible for driver comfort and safety. Below is a table with the most important circuits and their symbols to help you navigate the circuit.
| Fuse number | Designation | Denomination (A) | Protected node |
|---|---|---|---|
| F1 | RR FAN | 10 | Radiator fan (control) |
| F2 | ROOM | 10 | Interior lighting and shades |
| F3 | WIPER | 20 | Wiper motor |
| F4 | IG1 | 15 | Ignition system and control unit |
| F5 | ECU-IG | 10 | Engine control unit (ECU) |
Please note that some circuits may be duplicated or have multiple layers of protection. For example, the engine control system is protected both in the cabin and in the engine compartment. If the problem is not solved by replacing the cabin fuse, it is worth checking the main unit under the hood.
Save the fuse box diagram on your phone or print it out and put it in your glove compartment. In the event of a breakdown on the road, this will save you a lot of time searching for information on the Internet.
A correct understanding of the circuit allows you not only to fix the breakdown, but also to anticipate potential problems. If you notice that the fuse is blowing regularly, this is a signal that the leakage current in the circuit is increasing or vibration contact is occurring, requiring wiring repair.
Regularly checking the condition of fuses and cleaning contacts helps prevent sudden electronic failures on the road.
Typical problems and their solutions
Owners Nissan Almera Often we encounter a situation where after replacing the fuse the problem does not go away. This may be due to poor contact in the socket, oxidation of the leads, or a malfunction of the device itself. In such cases, it is necessary to carefully inspect the installation site.
- 🔦 Check the socket for traces of soot or melted plastic.
- 🧹 Clean the fuse contacts and socket with an alcohol wipe.
- 🔌 Make sure that the new element fits tightly and has no play.
Sometimes the problem lies not in the fuse, but in the relay that controls this consumer. The relays are located in the same block or next to it. Clicks from the relay when the device is turned on indicate its serviceability, and their absence indicates a malfunction of the relay itself or the control circuit.
⚠️ Warning: If you smell burning or see smoke from the fuse box, stop repairs immediately and call emergency services.
In rare cases, the control unit itself may fail, for example the comfort module or the power window control unit. This requires complex diagnostics using professional equipment. If simple methods do not help, you should not continue independent experiments with electrics.
How to distinguish an oxidized contact from a mechanical failure?
Oxidation appears as a white or green coating on the metal parts, while mechanical failure is a physical fracture or deformation of the plastic of the socket.
FAQ: Frequently asked questions
Where is the spare fuse located in Nissan Almera G15?
Typically, spare parts are located in a special compartment inside the fuse box cover or in the engine compartment. Sometimes they are attached to the inside of the lid using plastic clips.
Can I use a different color fuse?
No, the color corresponds to the current rating. Using a fuse of a different color (for example, replacing a red 10A with a yellow 20A) is dangerous and can lead to a fire in the wiring.
What should I do if the fuse burns out immediately after replacement?
This is a sign of a short circuit or consumer failure. It is necessary to disconnect the device and diagnose the wiring, since a simple replacement will not solve the problem.
How to check a fuse without a multimeter?
If the housing is transparent, you can visually inspect the jumper. You can also insert a fuse into the socket and have someone turn the device on, but this is less accurate and safe.
Do I need to disconnect the battery when replacing the fuse?
Officially not required if you change the fuse in the passenger compartment with the ignition off. However, for complete safety when working with main circuits, it is better to disconnect the negative terminal.
