Nissan Wingroad Y11: complete fuse diagram with decoding and replacement instructions

Nissan Wingroad Y11 (1996–2005) - a compact station wagon that has gained popularity due to its reliability and practicality. However, even in such a proven car, electrical problems periodically arise, and the first thing the owner checks is fuse box. Without a diagram and understanding of the purpose of each element, diagnostics turns into guessing at random.

In this article you will find detailed description of all fuses and relays for Wingroad Y11, their location in the cabin and under the hood, as well as step-by-step instructions for replacement. We took into account the features of different years of production (including the 1999 restyling) and typical mistakes that owners make when working with electrical equipment. If your Nissan suddenly stopped starting, the headlights do not work or the stove fails - here you will find out where to start checking.

Where is the fuse box located in Nissan Wingroad Y11

B Wingroad Y11 provided two main fuse boxes:

• 🔧 Main unit in the cabin — located to the left of the steering column, under the instrument panel. To gain access, you need to open the cover (it is secured with two latches) and snap it off with a flat-head screwdriver.
• 🚗 Additional block under the hood — located next to the battery, in a plastic box with a lid. Most often, high power fuses are located here (for example, for a cooling fan or injection system).

On models after 1999 (restyling), the location of the blocks has not changed, but in some trim levels a third mini-unit appeared under the glove compartment - it is responsible for the audio system and additional equipment. It's easy to miss if you don't know it exists.

Before searching for blocks, turn off the ignition and remove the negative terminal from the battery - this will protect against a short circuit if the wires accidentally touch.

Diagram and decoding of the cabin unit fuses

Salon block Wingroad Y11 contains 10–30 A fuses responsible for the main vehicle systems. Below is a table with a breakdown for models 1996–2005 (including restyling). Please note: fuse numbers may vary depending on year of manufacture and equipment.

Fuse no.	Denomination (A)	Purpose	Symptoms of a problem
1	10	Interior lighting, instrument lighting	The interior lights don't light up and the panel lights don't work.
5	15	Low beam (left headlight)	Low beam on one side does not work
10	20	Windshield wipers, windshield washer	The wipers or washer pump do not work
15	10	Audio system, cigarette lighter	The radio does not turn on, the cigarette lighter does not work
20	30	Heater (stove), fan	The heater does not blow or only works at maximum speed

The complete diagram with photographs of the block can be downloaded here (PDF, 1.2 MB). If your fuse does not match the table, check the year of manufacture: Wingroad Y11 1996–1998 numbering may vary.

⚠️ Attention: Fuse No. 12 (15 A) is responsible for ECU (electronic control unit). If it burns out, the car will not start. Never replace it with a “bug” - this can damage the entire unit!

Underhood fuse box: what's hidden there?

Engine compartment block Nissan Wingroad Y11 contains high power fuses (from 30 to 100 A) and relays responsible for critical systems:

• ⚡ Main fuse (100 A) - powers the entire on-board network. When it burns out, the car is completely de-energized.
• 🔥 Cooling fan fuse (50 A) - if it burns out, the engine will overheat.
• 🔋 Fuel pump relay - if there is a malfunction, the car will not start or will stall.
• 💡 Generator fuse (60 A) - if it burns out, the battery will not charge.

The location of relays and fuses in the engine compartment often causes confusion, since their designations do not always correspond to the diagram in the manual. For example, relay R1 may be responsible for cooling fan in one package and for headlights - in another.

To accurately determine the purpose, use by elimination:

1. Check all fuses visually for burnt contacts.
2. If everything looks intact, test them with a multimeter.
3. Compare the results with the table from complete scheme (see FAQ section).

⚠️ Attention: The generator fuse (60 A) is often confused with the starter fuse. If after replacement the car does not start, but the relay clicks, the problem is in the starter, and not in the generator.

How to test a fuse without a multimeter?

If you don't have a tester at hand, you can use a 12 V light bulb with two wires. Connect one wire to one fuse terminal, the other to the other. If the light comes on, the fuse is good.

Typical problems and their causes

Owners Nissan Wingroad Y11 often encounter repeated blown fuses. This signals more serious malfunction, which cannot be ignored. Let's look at the most common cases:

• 🔄 Heater fuse (20 A) lights regularly - the reason is fan motor shorted or damaged wiring. Check the resistance of the motor winding (should be ~10–20 Ohms).
• 💡 Headlight fuse blows (15 A) - oxidized contacts in lamp sockets or a short circuit in the wiring harness under the hood are to blame.
• 🔊 The audio system fuse (10 A) blows when the radio is turned on. - check positive wire for a short to ground (often frays near the glove compartment).

If the fuse blows immediately after replacement, don't try to install a more powerful one - this will lead to melting of the wiring or failure of the control unit. Instead:

1. Disconnect all consumers connected to this fuse.
2. Plug them back in one by one until you find the culprit.
3. Check the circuit for short circuit with a multimeter.

In models 1999–2005 There is often a problem with fuse No. 7 (10 A), which is responsible for the instrument panel. If after replacing it the speedometer and tachometer do not work, check the contacts on the instrument board - they may be oxidized.

Step-by-step instructions for replacing fuses

Replacing the fuse in Nissan Wingroad Y11 - a simple procedure, but requiring accuracy. Follow the instructions to avoid errors:

1. Preparation:
   • Turn off the ignition and remove the negative terminal from the battery.
   • Locate the fuse box (see section above).
   • Prepare a new fuse same denomination.
2. Removing the old fuse:
   • Take plastic tweezers (usually included with the block).
   • Carefully pry the fuse and pull it out.
   • If you don't have tweezers, use small pliers, but don't use too much force.
3. Installing a new one:
   • Insert the fuse until it clicks.
   • Make sure it fits snugly - poor contact can cause heat.
4. Check:
   • Connect the battery terminal.
   • Turn on the ignition and check the operation of the system.

If after replacement the fuse blows again, do not repeat the procedure - this is a sign of a short circuit. Contact an electrician or check the circuit yourself (see the “Diagnostics” section).

⚠️ Attention: In the underhood box, high power fuses (50-100 A) are often bolted on. To replace them you will need a 10 mm socket wrench. Do not use a screwdriver - this may damage the contacts!

Troubleshooting: When fuses blow repeatedly

If the fuse blows immediately after replacement, it means there is short circuit or overload. To find the reason, follow the algorithm:

1. Disable all consumers:

   Remove the terminal from the battery, disconnect all devices connected to the problematic fuse (for example, radio, fan, etc.).

2. Ring the chain:

   Set the multimeter to continuity mode and check the resistance between the positive wire of the circuit and ground. If the resistance is close to 0, there is a short circuit.

3. Check the wires:

   Inspect the harnesses for damage to the insulation, especially in kinked areas (under the hood, near the doors, under the seats).

4. Test one by one:

   Reconnect the consumers one at a time, checking the fuse each time. This way you will find the culprit.

Common causes of re-burnout:

• 🔌 Oxidized contacts in connectors (for example, in a heater or headlight unit).
• 🔥 Damaged wire insulationrubbing against metal parts of the body.
• 🔄 Faulty relays, which “stick” and cause overload.
• 💡 Installation of lamps or high power equipment (for example, xenon instead of halogen).

If you find a short circuit but cannot find its source, disconnect the problematic circuit and contact service. B Wingroad Y11 The wires under the hood are especially vulnerable - they often rub against the edges of the metal.

Frequently asked questions (FAQ)

Where can I download the complete fuse diagram for Nissan Wingroad Y11?

The full diagram in high resolution can be downloaded from this link: Nissan Wingroad Y11 Fuse Box Diagram (PDF). The archive also contains decoding of relays and fuses for different years of production (1996–2005).

Which fuse is for the cigarette lighter?

B Wingroad Y11 The fuse is responsible for the cigarette lighter No. 15 (10 A) in the salon block. If it is burnt out, check also wiring under the glove compartment — the insulation there is often frayed.

Is it possible to install a fuse of a higher rating?

No! Installing a higher fuse rating (for example, 20 A instead of 10 A) may result in wiring fire. If the fuse constantly blows, look for the cause - a short circuit or overload.

Why does the heater only work at 4th speed after replacing the fuse?

This is a sign of a problem heater resistor or speed switch. The fuse has nothing to do with it - check the resistance of the resistor (should be ~1–5 Ohms at different speeds).

How to check the relay in the fuse box?

To test the relay, follow these steps:

1. Remove the relay from the block.
2. Ring the contacts with a multimeter 85 and 86 (coil) - resistance should be ~50–120 Ohms.
3. Connect 12V to pins 85 (+) and 86 (–) - there should be a click.
4. Call contacts 30 and 87 — in the closed state, the resistance should be ~0 Ohm.

If the relay does not click or there is no continuity, it needs to be replaced.
