Removing the fuse box on Nissan Almera Classic (models B10 And N16) is a task that every owner faces sooner or later. The reasons may vary: from replacing a blown fuse to diagnosing electrical circuits or repairing wiring. However, not everyone knows that improper dismantling can lead to damage to connectors, short circuit or even failure of on-board electronics.

In this article we will look at the process of removing the fuse box. step by step, taking into account the design features Almera Classic. You will find out what tools you will need where the main and additional blocks are located, as well as how to avoid common mistakes. We will pay special attention security — after all, working with electricians requires accuracy and knowledge of the nuances.

Where is the fuse box located on Nissan Almera Classic

B Nissan Almera Classic provided two main fuse boxes:

  • 🔧 Main unit — located in the cabin, under the instrument panel on the driver’s side. It is easy to find if you remove the cover under the steering wheel.
  • ⚡ Additional relay block - located in the engine compartment, next to the battery (on some modifications - under a plastic cover).

The exact location may vary slightly depending on the year of manufacture and equipment. For example, in models N16 (2000–2006) the main block is often hidden deeper than in B10 (1995–2000), where it is available almost immediately after the cap is removed. To avoid mistakes, be guided by marking on the block cover - usually there is a diagram there.

If you are not sure which block needs to be removed, check electrical diagram for your model. It can be found in instruction manual or on specialized forums (for example, drive2.ru or nissan-club.ru).

Preparing for removal: tools and safety precautions

Before you begin dismantling, prepare everything you need. Lack of tools or rush - the main causes of damage to connectors or broken wires.

  • 🔨 Flat head screwdriver (for removing plastic latches).
  • 🔧 Phillips screwdriver (may be needed to unscrew the panel fastening screws).
  • 🔌 Plastic puller or a thin ruler (to pry off the lid without scratching).
  • 📸 Smartphone — take a photo of the location of the fuses and relays before removing!
  • 🔋 Multimeter (to check the chains after dismantling).

Important! Before work be sure to disconnect the battery. To do this:

  1. Turn off the ignition and remove the key.
  2. Open the hood and loosen the nut on negative terminal battery
  3. Remove the terminal and insulate it (for example, wrap it with a rag).

If you are working with additional unit under the hood, make sure the engine is completely cool - some relays may be hot after driving.

💡

If the block latches are too tight, spray them with silicone lubricant (for example, WD-40 Specialist) - this will make it easier to remove without breaking.

Step-by-step instructions: how to remove the main fuse box in the passenger compartment

Main unit in the cabin Nissan Almera Classic fastened with latches and sometimes with one or two self-tapping screws. The removal process takes 10–15 minutes if you act carefully.

☑️ Preparing to remove the fuse box

Done: 0 / 4
  1. Remove the decorative cover under the steering wheel. It is secured with 2-3 plastic latches. Use a screwdriver or puller to pry it off on the left side and pull it towards you.
  2. Unscrew the screws (if they exist). In some modifications, the block is fixed with one screw at the bottom.
  3. Disconnect the connectors. The fuse box is connected to the wiring via 1-2 plugs. Gently press the latches and pull them out. Do not pull on the wires - only on the connector housing!
  4. Remove the block. It should come out effortlessly. If something is in the way, check that all the latches are unfastened.

After removal, inspect the unit for melted contacts or oxidation. If there are signs of corrosion, clean them contact cleaner (For example, Kontakt 60).

What to do if the block cannot be removed?

If the block is stuck, check:

- Did you forget to unfasten the hidden latch (sometimes it is hidden behind the panel).

- Is there an additional fastening on the back side (you will have to remove the glove compartment).

- Are the guides bent? In this case, the block may cling to the body.

Removing the additional fuse box under the hood

An additional unit (most often with a relay) is located next to the battery. Its removal is easier, but requires caution due to its close location to power wiring.

  1. Remove the plastic cover (if there is one). It is attached with latches or one bolt.
  2. Disconnect the battery terminals (if you haven't done this before).
  3. Press the block latches. Usually there are two of them - on the sides. Click on them and pull the block up.
  4. Disconnect the connectors. They can be firmly fixed - do not use force, it is better to check that all the latches are unfastened.

Relays are often located in this block main relay, cooling fan And fuel pump. If you are removing it for diagnostic purposes, label the relay (for example, tape with numbers) - when reassembling it is easy to mix them up.

⚠️ Attention! Do not touch the metal parts of the block and body at the same time - this may cause static voltagewhich will damage the electronics.

Common mistakes and how to avoid them

Even experienced car owners sometimes make mistakes when working with the fuse box. Here are the most common of them:

Error Consequences How to avoid
Removing the unit without disconnecting the battery Short circuit, blown fuses, ECU failure Always disconnect negative terminal before work
Use of force when removing connectors Broken wires, damaged contacts Check all fasteners, use a puller
Mixed-up fuses/relays during reassembly Devices that do not work (such as headlights or power windows) Photograph or mark items before removal
Ignoring contact oxidation Poor contact, overheating, re-blown fuses Clean your contacts contact cleaner or fine sandpaper

Another typical problem is damage to plastic latches block covers. If they break, the unit will wobble and the fuses may fall out. In this case, the latches can be restored using epoxy glue or replace the entire cover (part number of the original part - 28550-4M000 for N16).

Checking and diagnostics after removal

After removing the fuse box be sure to carry out diagnostics:

  • 🔍 Visual inspection: Check the fuses for integrity (a blown fuse has a broken thread inside).
  • 📊 Testing with a multimeter: Set the circuit test mode and test each fuse for continuity.
  • 🔌 Cleaning contacts: If there is oxidation, use special liquid or WD-40 (but not for relay contacts!).

If you removed the block due to constant blowing of fuses, look for the reason in:

  • Short circuit in wiring (check harnesses under the hood and at the door).
  • Consumer faults (e.g. stove motor or window regulator).
  • Poor contact in connectors (can cause voltage surges).

To check circuits, use electrical diagram your model. For example, for Nissan Almera Classic N16 the diagram from service manual EWM5E-0N160.

💡

If the fuse blows immediately after replacement, the problem is in the circuit, not in the fuse itself. Do not install a fuse with a larger rating - this may cause a fire!

Reinstalling the fuse box

Fuse box assembly Nissan Almera Classic must take place in reverse order, but taking into account several nuances:

  1. Check all connectors for damage. If the contacts are bent, straighten them thin screwdriver.
  2. Install fuses and relays into place (refer to photographs or markings).
  3. Connect the connectors until they click - they should be fixed clearly, without play.
  4. Secure the block onto the screws (if there were any) and snap the lid on.
  5. Connect the battery and check the operation of all systems (headlights, power windows, heater).

If after installation something does not work (for example, Dimensions do not light up or cigarette lighter doesn't work), check:

  • Correct installation fuses (the denomination must match!).
  • Contact density in connectors (sometimes they don't sit all the way).
  • Integrity postings from the block to the consumer.
⚠️ Attention! If the lamp comes on after assembly Check Engine or errors appear on the dashboard, reset them using OBD-II scanner or by disconnecting the battery for 10 minutes. This may be a false alarm due to a temporary loss of power to the ECU.
