Where is the fuse box located in Nissan Almera Classic

B Almera Classic installed two main fuse boxes:

• 🔧 Main unit — located in the cabin, under the instrument panel on the driver’s side. To access it, you need to open the cover, which is located to the left of the steering column (next to the clutch pedal).
• ⚡ Additional relay block — located in the engine compartment, next to the battery. It is protected by a plastic cover that is secured with latches.

Also in some configurations may be present third block — it is located behind the glove compartment and is responsible for the audio system and climate control (if installed). However, in most basic versions Almera Classic he's not there.

To get to the cabin unit:

1. Sit in the driver's seat and turn the steering wheel to the left all the way.
2. Find the plastic cover that says FUSE or FUSES.
3. Press the latch at the top of the cover and pull it towards you.

⚠️ Attention: Do not try to open the fuse box cover with force - it is secured with plastic clips that are easy to break. If the cover does not budge, check to see if it is caught on the wiring harness.

Diagram and decoding of the cabin unit fuses

In the salon block Nissan Almera Classic installed 30–35 fuses (depending on the year of manufacture and configuration). Below is the standard layout for most versions:

Fuse no.	Denomination (A)	Purpose
1	10	Side light (left side), license plate light
7	10	Cigarette lighter, 12V socket in trunk
10	15	Engine control unit (ECU), fuel pump
15	20	Power windows (all four doors)
20	10	Audio system, antenna, navigation (if installed)

You can find a complete diagram with decoding of all fuses on the back of the unit cover or in instruction manual (section Electrical equipment). If you don't have a manual, download it in PDF from this link (select model Almera Classic N16).

The most "problematic" fuses in Almera Classic:

• 🔥 No. 7 (10A) - cigarette lighter. Burns out due to the use of powerful devices (for example, car vacuum cleaners or compressors).
• ⚡ No. 10 (15A) — ECU and fuel pump. If this fuse is blown, the car will not start.
• 🚗 No. 15 (20A) — power windows. It often fails when the glass freezes or foreign objects get into the mechanism.

Engine compartment relay block: location and purpose

Second fuse and relay box in Nissan Almera Classic located under the hood, next to the battery. He is responsible for main power circuits: starter, generator, cooling fans, headlights, etc.

To access this block:

1. Open the hood and look for a black plastic box with a lid (usually located to the right of the battery).
2. Press the two latches on the sides of the cover and remove it.
3. Under the cover you will see fuses (top) and relays (bottom).

Interpretation of key relays in the engine compartment:

Designation	Purpose
R1	Starter relay
R3	Cooling Fan Relay (Low Speed)
R5	Fuel pump relay
R7	Low beam relay

If one of the relays fails, it can be replaced with a similar one from another slot (for example, the fan relay and starter relay are often interchangeable). However, if the problem persists, you should check the circuit for short circuit or a malfunction of the device itself (for example, a starter or fuel pump).

⚠️ Attention: Never replace relays or fuses with parts of a different rating! For example, installing a 20A fuse instead of 10A may result in fire in the wiring.

How to test a relay with a multimeter?

To test the relay, connect a multimeter in test mode to pins 85 and 86 (coil). The resistance should be between 50–120 Ohms. Then apply 12V voltage to these contacts - you should hear a click. If there is no click, the relay is faulty.

How to replace a fuse or relay in Nissan Almera Classic

Replacing a fuse is a simple procedure, but even here there are nuances. Here step by step instructions:

Next:

1. Using tweezers (usually attached inside the block cover), remove the burnt fuse.
2. Check it for clearance - if the thread inside is burned out, the fuse must be replaced.
3. Install a new fuse same denomination (color and number on the case must match).
4. Check the operation of the circuit (for example, turn on the cigarette lighter or headlights).

If the fuse blows again, don't replace it again is a sign short circuit in the chain. In this case it is necessary:

• 🔍 Check the wiring for damage (especially in kinks or near moving parts).
• 🛠️ Disconnect consumers connected to this fuse (for example, a radio or additional equipment).
• 📊 Test the circuit with a multimeter to check for a short to ground.

To replace the relay:

1. Gently pull the relay up (it is held in place by latches).
2. Install the new relay, making sure the contacts match.
3. Check the operation of the device (for example, turn on the fan or try to start the car).

Common problems with fuses and their solutions

Owners Nissan Almera Classic often encounter typical problems related to fuses. Let's look at the most common ones:

1. The cigarette lighter fuse blows (No. 7, 10A)

Reasons:

• 🔌 Use of powerful devices (compressor, vacuum cleaner, inverter).
• 🔥 Short circuit in the 12V socket (for example, due to metal objects).
• 📻 Audio system malfunction (if it is connected to the cigarette lighter).

Solution: Replace the fuse with 10A. If it burns out again, check the outlet for a short or connect the device directly to the battery through a separate fuse.

2. Power windows do not work (fuse No. 15, 20A)

Reasons:

• ❄️ Freezing of glass or lift mechanism.
• 🔧 Worn out guides or window lift motor.
• 🔌 Short circuit in the control button.

Solution: Check to see if the glass is jammed. If the fuse blows when the button is pressed, disassemble the door card and check the wiring.

3. The car does not start (fuse No. 10, 15A)

If the fuse ECU or the fuel pump is burnt out, the engine will not start. What to do:

• 🔧 Replace the fuse and try to start the car.
• 🛢️ If the fuse blows again, check the fuel pump (it may be stuck).
• 📊 Ring the circuit from the fuse to ECU for a short circuit.

If the problem persists, it may be that the ECU or there are problems with the wiring under the hood (for example, frayed wires near the exhaust manifold).

How to avoid blown fuses again

To keep the fuses in Nissan Almera Classic last longer, follow these tips:

• 🔌 Do not overload the circuits. Do not connect devices with a power of more than 120 W (for example, car refrigerators) to the cigarette lighter. Use a separate fused outlet.
• 🔧 Check your contacts. Oxidized or burnt contacts in the fuse box can cause overheating. Clean them with alcohol or a special contact liquid.
• 🛠️ Keep an eye on the wiring. Inspect wiring harnesses regularly for damage, especially in areas where they rub against the body (such as under the hood or in door frames).
• ❄️ Avoid moisture. If water gets into the fuse box (for example, after washing), dry it with a hairdryer or compressed air.

If you are installing additional equipment (such as an alarm, camera or amplifier), be sure to connect it via a separate fuse. You cannot “hang” powerful consumers on standard circuits - this will lead to blown fuses or even a fire.

It is also recommended to carry out once a year preventive examination fuse box:

1. Remove the unit cover and inspect the fuses for darkening or melting.
2. Check the unit for debris, dust, or moisture.
3. Make sure all fuses are of the correct rating (sometimes previous owners installed bugs or fuses of higher ratings).
