Nissan Terrano: location and decoding of fuses (diagrams + replacement tips)

Nissan Terrano is one of the most popular SUVs on the Russian market, but even such a reliable car has problems with electrical equipment. Most often the culprit is burnt out fuses or faulty relay. If your cigarette lighter does not work, the headlights fail, the heater does not turn on, or the dashboard is flashing, the first thing you should do is check the fuse boxes.

In this article you will find detailed fuse diagrams for Nissan Terrano R50 (1st generation), Terrano II R20 (2nd generation) and restyled versions, as well as unique tips for diagnosing faults that cannot be found in standard manuals. We will look at how to properly replace fuses, what tools you will need, and what to do if the problem does not go away after replacement.

Where are the fuse boxes in the Nissan Terrano?

B Nissan Terrano fuses and relays are distributed over several blocks. Their location depends on the generation and year of manufacture of the car. The following are standard installation locations:

• 🔧 Main fuse box — located in the cabin, under the instrument panel on the driver’s side. To gain access, you need to open the cover (usually it is secured with latches).
• 🔋 Relay and fuse box under the hood - located next to the battery (in Terrano R20 can be hidden by a plastic cover).
• ⚡ Additional block — in some trim levels it is found next to the steering column or in the glove compartment.

B Terrano 1st generation (R50) The main fuse box is often hidden behind a plastic panel to the left of the steering wheel. B Terrano 2nd generation (R20) it was moved closer to the center console, and in restyled versions (for example, Terrano 2014+) added a second unit under the hood to protect the generator and starter circuits.

If you can't find the fuse box, look at marking on the lid - usually there is a diagram or part number that can be used to determine the purpose of each fuse.

Also in this generation a fuse appeared F30 (10A) for immobilizer. If the car does not start, but the starter turns, check this fuse and relay K12.

What to do if the fuse keeps blowing?

If the fuse blows again after replacement, there is a short circuit in the circuit. Do not replace the fuse with a more powerful one - this may lead to a fire in the wiring! You need to check the circuit with a multimeter or contact an auto electrician.

How to properly replace a fuse in a Nissan Terrano?

Replacing a fuse is a simple procedure, but there are several nuances that will help you avoid mistakes. Here are the step-by-step instructions:

1. Turn off the ignition and remove the negative terminal from the battery (especially important when working with the unit under the hood).
2. Find the faulty fuse. Typically a blown fuse has broken thread or melted body.
3. Use plastic tweezers (often included with the fuse box) to remove the blown fuse.
4. Install a new fuse same denomination. Do not install a fuse with a large ampere under any circumstances!
5. Check the operation of the circuit. If the fuse blows again, look for a short circuit.

To work you will need:

• 🔧 A set of fuses (it is advisable to have a supply of 10A, 15A, 20A, 30A).
• 🔍 Flashlight (to better see the markings).
• 📸 Multimeter (to check the voltage in the circuit).

If the fuse blows again after replacement, this may indicate:

• Short circuit in the wiring.
• Malfunction of the consumer (for example, a stove motor or fan).
• Problems with ground (poor contact on the body).

⚠️ Attention: B Nissan Terrano with diesel engines (TD27, YD25) fuse F15 (30A) responsible for the cooling fan. If it burns out, the engine may overheat! Before replacing, check to see if the fan is jammed.

Common fuse problems and their solutions

Owners Nissan Terrano often encounter typical faults related to fuses. Here are the most common problems and how to fix them:

1. The cigarette lighter does not work

If the cigarette lighter stops working, check:

• 🔌 Fuse F10 (20A) in the main block.
• 🔋 Fuse F20 (15A) in the block under the hood (if equipped).
• 🔍 Contacts in the cigarette lighter socket (often oxidize).

If the fuses are intact, the problem may be wiring or in the cigarette lighter itself. Try connecting another consumer (for example, a compressor) - if it does not work, then there is a problem in the circuit.

2. Headlights do not light (low/high beam)

If the headlights do not work, check:

• 💡 Fuses F3 (15A) And F4 (15A) for low beam.
• 💡 Fuses F5 (10A) And F6 (10A) for high beam.
• 🔦 Relay K3 (low beam) and K4 (high beam) in the block under the hood.

If fuses and relays are good, check lamps And wiring. B Terrano R20 The wires in the corrugation near the headlights often fray.

3. The heater or heater fan does not work

Problems with the stove are usually associated with:

• ❄️ Fuse F14 (30A) (heater fan).
• 🌀 Relay K5 in the block under the hood.
• 🔌 Poor contact on the stove motor connector.

If the fan does not work at any speed, check heater resistor (located next to the motor). B Terrano R50 it often breaks down.

4. The rear wiper or washer does not turn on

B Nissan Terrano rear wiper and washer are protected by a fuse F8 (15A). If it is OK, check:

• 💦 Washer pump (may become clogged or burn out).
• 🔄 The wiper motor (often jams due to corrosion).
• 🔌 Fuse F22 (10A) — responsible for the wiper relay.

How to check fuse and relay without a multimeter?

If you don’t have a multimeter at hand, you can check the fuse and relay using improvised means:

Checking the fuse

The easiest way is visual inspection:

1. Remove the fuse from its socket.
2. Look in the light - if the thread inside is broken or the body is melted, the fuse has burned out.
3. If everything is visually normal, you can check "to the spark": Briefly touch the fuse contacts to the “+” and “ground” of the battery. If the fuse is good, it should not blow.

Relay test

To test a relay without a multimeter:

1. Remove the suspect relay from the block.
2. Shake it - if something rattles inside, most likely the relay is faulty.
3. Swap with a known good relay (such as a fan or horn relay). If after replacement the problem disappears, then the relay was faulty.

B Nissan Terrano relays often fail due to contact oxidation. If the relay “clicks” but the circuit does not close, clean the contacts WD-40 or contact lubricant.
