<em>Nissan Juke</em> headlight fuse: location, replacement and fault diagnosis

Nissan Juke is a compact crossover with a bright design, but even it has electrical problems. One of the most common problems is failure of low or high beam headlights. In 70% of cases, the burnt-out is to blame fuse, not the light bulb or wiring. However, finding it is not so easy: depending on the year of manufacture (Juke J10 2010–2014 or J11 2014–2019) the fuse box diagram is different, and the ratings may vary.

In this article we will look at where exactly to look for the headlight fuse on Nissan Juke, how to check it with a multimeter (even without experience), what mistakes owners make when replacing it, and why sometimes replacing a fuse does not solve the problem. We will also provide current block diagrams for different generations and tell you how to distinguish a blown fuse from a faulty relay or wiring.

Where is the headlight fuse located? Nissan Juke

B Nissan Juke headlight fuses are located in main fuse box, which is located in the cabin under the steering wheel. The exact location depends on the generation:

• 🔧 Juke J10 (2010–2014): The unit is hidden behind a plastic cover to the left of the steering column. To gain access, you need to rotate the three latches 90° and remove the cover.
• 🔧 Juke J11 (2014–2019): the unit was moved a little higher, under the instrument panel. The cover is secured with two latches - pull it towards you with force.
• ⚡ Both generations: an additional relay block (including the headlight relay) is located in the engine compartment, next to the battery.

Important: on some versions Juke with xenon headlights the fuse is only responsible for halogen lamps (for example, fog lights or high beams). Xenon is controlled through a separate ignition unit, and its fuse is looked for elsewhere (more on this in the diagnostics section).

The fuse box diagram is usually printed on the back of the cover. If it is missing or erased, use the table below.

Generation	Fuse number	Rating (A)	Responsible for
J10 (2010–2014)	38	10	Low beam (right headlight)
J10 (2010–2014)	39	10	Low beam (left headlight)
J11 (2014–2019)	42	15	Low and high beam (both headlights)
J11 (2014–2019, restyling)	45	10	Fog lights

⚠️ Attention: On Juke with automatic headlight switching on (optional Auto Light System) the fuse can be duplicated in the block under the hood. If the light does not come on after replacement, check the fuse #10 in the engine compartment (rated 15A).

How to check a headlight fuse with a multimeter

Before replacing the fuse, make sure that this is the problem. To do this, you will need a multimeter (or at least a test light). Verification algorithm:

1. Turn off the ignition and remove the fuse with tweezers (it is located in the block, next to the spare fuses).
2. Put the multimeter into test mode chains (diode or resistance icon).
3. Touch the probes to the fuse contacts. If resistance 0 ohm - the fuse is OK. If OL (break) - burned out.

An alternative method without instruments: visually inspect the fuse in the light. Burnt out will have broken thread inside or blackened contacts. However, this method is unreliable - sometimes the break is not visible to the naked eye.

If the fuse is good, but the light does not work, the problem may be:

• 💡 Light bulb (check for functionality by replacing it with a known good one).
• 🔌 Headlight relay (in the engine compartment, usually #5 or #7).
• 🔧 Wiring (check the voltage at the headlight connector with a multimeter).

Step-by-step instructions for replacing the fuse

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

1. Turn off the ignition and remove the key from the lock.
2. Remove the fuse box cover (as described in the section above).
3. Find the burnt fuse by number (see table) and remove it with tweezers.
4. Install a new fuse same denomination. Using a fuse with a large amperage may cause a fire in the wiring!
5. Turn on the headlights and check their operation.

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

• 🔍 Check the wiring for exposed wires or melted insulation.
• 💡 Make sure that the headlight bulb is installed correctly (poor contact can cause a short circuit).
• 🚗 Contact an auto electrician to diagnose the circuit.

⚠️ Attention: Never use “bugs” (homemade wire jumpers) instead of a fuse! This may cause a fire in the vehicle. On Juke with its dense wiring layout the risk is especially high.

Common mistakes when replacing headlight fuse

Even experienced drivers sometimes make mistakes that lead to repeated failure of the fuse or damage to the electronics. Here are the most common:

• ❌ Installing a fuse wrong denomination. For example, instead of 10A they put 15A, thinking that “it’s more reliable.” This leads to overheating of the wiring.
• ❌ Using fuses another type. On Juke there should be fuses mini blade (flat). "Old" cylindrical fuses will not work.
• ❌ Replacement of only one fuse when parallel connection. If both headlight fuses are blown (for example, #38 And #39 on J10), both need to be changed - even if the second one is “outwardly intact”.
• ❌ Ignoring verification headlight relay. If the relay is stuck or fails, the new fuse will blow as soon as the light turns on.

Another common mistake is misdiagnosis. For example, if only one headlight does not work, the owners immediately blame the fuse, although the problem may be in the light bulb or connector. Always start with the simplest:

1. Check the light bulb.
2. Make sure the headlight connector is not oxidized.
3. Only then check the fuse.

What should I do if the fuse blows again?

If the new fuse blows immediately after replacement, this indicates a short circuit. Do not try to install a fuse of a higher rating! Disconnect the headlight from the connector and check the circuit with a multimeter in “continuity” mode. If the short circuit is confirmed, contact an auto electrician - repairing the wiring yourself without experience is dangerous.

Fuse vs. headlight relay: how to distinguish problems

If replacing the fuse does not help, the culprit may be headlight relay. It is responsible for turning the light on/off and is located in the engine compartment. Signs of a relay malfunction:

• 🔦 The headlights do not turn on at all (even after replacing the fuse).
• 🔦 The light flickers or is unstable.
• 🔦 Clicking noises are heard from under the hood when trying to turn on the headlights.

To test the relay:

1. Locate the headlight relay in the engine compartment (usually #5 or #7, see diagram on the unit cover).
2. Remove the relay and replace it with a known good one (for example, a fan or heated window relay).
3. If the headlights work, replace the relay. If not, the problem is in the wiring or the light control unit.

On Nissan Juke The headlight relay often fails due to moisture getting into the unit (especially if the car is operated in a rainy climate). To extend the life of the relay, you can:

• 🛠️ Process block contacts silicone grease (For example, Liqui Moly Silicon-Spray).
• 🛠️ Install additional protection on the fuse box (for example, a neoprene cover).

Symptom	Probable Cause	Solution
One headlight doesn't work	Light bulb, fuse or connector	Replace the light bulb → check the fuse → clean the contacts
Both headlights don't work	Fuse, relay or control unit	Check the fuse → replace the relay → diagnostics of the unit
Headlights are flashing	Faulty relay or poor contact	Replace the relay → check the ground of the headlights

How to extend the life of headlight fuses

Frequent blowing of headlight fuses Nissan Juke - a signal about problems in the electrical circuit. To avoid this:

• 💡 Use quality light bulbs (For example, Philips X-treme Vision or Osram Night Breaker). Cheap Chinese lamps often produce current surges.
• 🔌 Regularly clean headlight contacts from oxidation (use WD-40 or Contact Cleaner).
• 🚗 Check the voltage in the on-board network. If it exceeds 14.5V, the fuses will burn more often. The reason is a faulty generator or relay regulator.
• 🔧 Install additional fuse box with surge protection (For example, Blue Sea ST Blade).

If you frequently drive off-road or in rainy weather, we recommend:

• 🛡️ Seal headlight connectors silicone sealant.
• 🛡️ Install additional mass to the body (poor ground contact is a common cause of short circuit).

Frequently asked questions about headlight fuses Nissan Juke

Is it possible to drive without a headlight fuse if it is blown?

No! The fuse protects the wiring from overheating and fire. If it is removed, a short circuit can cause the entire circuit or even the machine to burn out. As a last resort, use a fuse with same denomination, but don't leave the nest empty.

Why on mine Juke J11 Does the headlight fuse blow every week?

This indicates short circuit or increased resistance in the chain. Common reasons:

• Exposed wire in the headlight harness (check the insulation).
• Oxidized contacts in the lamp connector.
• Faulty headlight relay (sticks and gets hot).
• Problems with the generator (battery overcharging).

We recommend contacting an auto electrician for a complete diagnosis.

Where to buy fuses for Nissan Juke?

Fuses mini blade (10A, 15A) are sold at any auto store or Wildberries/Ozon. Recommended brands:

• Hella (Germany) - reliable, but more expensive.
• Bosch — optimal price/quality ratio.
• SAT (Russia) - budget option.

Cost - from 5 to 50 rubles per piece. Take with reserve (at least 5 pieces of each denomination).

Can I use a fuse from another machine?

Yes, if it fits type (mini blade) and face value (10A or 15A). The fuses are universal, the main thing is not to install a 20A or 30A fuse instead of a 10A one.

How to test the headlight relay without a multimeter?

You can “ring” the relay by ear:

1. Turn on the ignition and headlights.
2. Listen to the engine compartment unit - a working relay makes a clear click.
3. If there is no click or it is weak, the relay is faulty.

You can also swap a relay with one that is known to work (for example, a fan relay).
