Cigarette lighter fuse on Nissan Sunny: location, replacement and typical problems

Cigarette lighter in Nissan Sunny - one of the most popular elements of electrical equipment, especially if you actively use car gadgets: recorders, navigators or chargers. However, its sudden failure is often associated not with a breakdown of the socket itself, but with a burnt-out fuse. In this article we will look at where the cigarette lighter fuse is located on different generations Sunny (B13, B14, B15), how to check and replace it, and why it may burn out again and again.

Feature Nissan Sunny — the location of the fuse box is not always obvious. Depending on the year of manufacture and the sales market (Japan, Europe, Asia), the scheme may differ. We have collected current data for all modifications, including rare versions with two cigarette lighters (for example, in taxi versions). You will also learn how to avoid common replacement mistakes that lead to short circuits or failure of other electrical appliances.

Where is the cigarette lighter fuse on a Nissan Sunny?

Most models Nissan Sunny (1990–2006) The cigarette lighter fuse is located in main fuse box, which is located to the left of the steering column, under the instrument panel. However, its exact location varies by generation:

• 🔧 B13 (1990–1995): The cigarette lighter fuse is marked as CIGAR or POWER OUTLET, denomination - 15A. The block is hidden behind a plastic cover, which is secured with two latches.
• 🔧 B14 (1995–2000): the fuse can be labeled as ACC or SOCKET (nominal 15–20A). On some versions for the Japanese market it is duplicated in an additional block under the glove compartment.
• 🔧 B15 (2000–2006): The cigarette lighter fuse is usually located in the main unit under number #15 (15A) or #20 (20A). On models with two sockets (for example, for rear passengers), there may be a separate fuse.

To accurately identify the correct fuse, pay attention to diagram on the back of the block cover. If it is missing or worn out, use the universal method: the cigarette lighter fuse is always connected to the wire red or yellow with a thick section (usually 1.5–2.5 mm²).

How to check the cigarette lighter fuse

Before replacing the fuse, be sure to make sure that this is the problem. For this you will need multimeter or a simple test lamp. Verification algorithm:

1. Turn off the ignition and remove the key from the lock.
2. Remove the fuse box cover and locate the correct element (see section above).
3. Remove the fuse using tweezers (usually included with the unit).
4. Turn the multimeter into circuit test mode (dialing) and touch the fuse contacts with the probes. If the device shows 0 ohm — the fuse is good; if OL (break) - burned out.

An alternative method is visual inspection. A blown fuse often has melted thread or blackened body. However, this method is not reliable for micro-tears, so it is better to use a tester.

Step-by-step fuse replacement

Replacing the cigarette lighter fuse with Nissan Sunny takes no more than 5 minutes, but requires care. Follow the instructions:

1. Open the fuse box cover by pressing the latches on the sides.
2. Using tweezers, remove the burnt fuse. Do not use metal tools - they can damage the contacts.
3. Install a new fuse same denomination. Using a fuse with a higher amperage (for example, 25A instead of 15A) will lead to a risk of fire in the wiring!
4. Close the unit cover and check the operation of the cigarette lighter by connecting a known working device (for example, a USB charger).

If the fuse blows again after replacement, this indicates short circuit in the chain. In this case, you need to check:

• 🔌 The cigarette lighter socket itself for the presence of foreign objects (coins, paper clips).
• 🔌 Wiring from the cigarette lighter to the fuse box (often rubbed under the dashboard).
• 🔌 Connected devices - some cheap chargers or inverters can cause overload.

What should I do if the fuse burns out immediately after replacement?

This is a sign of a short circuit. Do not install a new fuse until the cause has been eliminated! Disconnect the cigarette lighter from the circuit (remove the terminal from the battery and disassemble the socket) or contact an auto electrician. A common cause is melting of the contacts inside the socket or a short circuit of the positive wire to ground.

Fuse ratings and types for Nissan Sunny

B Nissan Sunny standard size fuses are used ATO (miniature knife ones). The following ratings are relevant for the cigarette lighter:

Generation	Fuse rating	Case color	Notes
B13 (1990–1995)	15A	Blue	On some versions - 20A (yellow)
B14 (1995–2000)	15A or 20A	Blue/Yellow	Depends on the configuration (one or two cigarette lighters)
B15 (2000–2006)	20A	Yellow	On models with a rear cigarette lighter - a separate 15A fuse

Important: never use “bugs” (homemade jumpers made of foil or wire) instead of a fuse! This may lead to fire in the cabin due to overheating of the wiring. If you don't have the original fuse on hand, you can temporarily install a fuse with a lower rating (for example, 10A instead of 15A), but only for the trip to the store.

Typical causes of a blown fuse

If the cigarette lighter fuse blows regularly, the problem lies not in the cigarette lighter itself, but in the load or circuit. Let's look at the main reasons:

• ⚡ Short circuit in socket: metal objects (coins, paper clips) entering or contacts melting due to a poor connection.
• ⚡ Circuit overload: use of powerful devices (inverters 12V→220V, car refrigerators) without an additional relay.
• ⚡ Malfunction of connected gadgets: Cheap chargers or recorders can produce current surges.
• ⚡ Wiring damage: frayed or oxidized wires under the dashboard (especially important for Sunny B13/B14 over 20 years of age).

To diagnose the problem, unplug all devices from the cigarette lighter and replace the fuse. If it burns out again without load, there is an issue in the wiring or socket. If the fuse holds, but burns out when connecting a specific device, the gadget is to blame.

⚠️ Attention: on Nissan Sunny B15 with factory radio Clarion The cigarette lighter fuse is sometimes a circuit with the audio system. If the radio stops working after replacement, check the fuse. #10 (10A) in the main unit.

How to disassemble and repair the cigarette lighter socket

If the fuse is good but the cigarette lighter does not work, the problem may be in the socket itself. Disassembly and repair take 15–20 minutes. You will need:

• 🔧 Flat screwdriver (for removing cladding).
• 🔧 Soldering iron and solder (if soldering of contacts is needed).
• 🔧 Sandpaper (for cleaning oxidation).

Instructions:

1. Disconnect the negative terminal of the battery.
2. Remove the trim around the cigarette lighter (usually it is secured with latches).
3. Disconnect the power connector from the socket. Check the contacts for oxidation or burning.
4. If the socket is collapsible, unscrew the screws and inspect the internal “petals” (they often burn out). Sand them with sandpaper.
5. Reassemble everything in reverse order and check operation.

If the socket is not removable or is badly damaged, replace it with a new one. The cost of the original socket for Sunny - about 800-1500 rubles, analogue - 300-600 rubles. When purchasing, pay attention to polarity: y Nissan The positive contact is usually located in the center, and the negative contact is on the sides.

Frequently Asked Questions

Can I use a 25A fuse instead of a 15A fuse?

No! Installing a fuse with a large rating will lead to the risk of melting the wiring. Maximum permissible value for cigarette lighter Sunny — 20A (for models with two sockets).

Why does the cigarette lighter work but the fuse gets hot?

This is a sign increased resistance in the chain. Reasons: oxidized contacts in the socket, thin wires or a poor-quality fuse. Replace the fuse with the original one and check the connections.

Where to buy a fuse for Nissan Sunny?

Standard fuses ATO sold in any auto store (price - 10–50 rubles per piece). For Sunny brands will do Hella, Bosch or Littelfuse. Original fuses Nissan (article 24540-31U00) are less common, but have no advantages over their analogues.

How to check the cigarette lighter circuit without a multimeter?

Can be used control lamp (12V). Connect one end to ground, and the other one touch the fuse terminals one by one. If the lamp lights up on both terminals, the fuse is good. If only on one, it burned out.

What should I do if, after replacing the fuse, the radio fuse also burns out?

This indicates short circuit in the common circuit. On Sunny B14/B15 The cigarette lighter and radio are sometimes connected to the same harness. Check the wiring from the fuse box to the cigarette lighter for exposed wires.
