Nissan Presage U30 - compact van, Released in 1998 and produced until 2009. Despite the reliability of the model, electrical equipment requires attention over time, and fuses are one of the most vulnerable parts. If your headlights, windshield wipers or cigarette lighter stop working, the first thing you should check is fuse box. In this article we will look at where they are located, how to correctly diagnose and replace them, and also provide a complete explanation of the circuit for Presage U30 with gasoline and diesel engines.
The peculiarity of this model is the presence two main fuse blocks: one in the cabin, the other under the hood. In addition, some relays and fuses may be duplicated or different depending on the configuration (for example, versions with AWD or 2WD). We have taken into account all the nuances so that you can quickly find the element you need without unnecessary searching.
Where are the fuse boxes located in Nissan Presage U30
B Presage U30 fuses and relays are distributed over three main zones. Their location is standardized, but may vary slightly depending on the year of manufacture (1998–2003 vs 2004–2009) and the sales market (Japan, Europe, Asia).
Main places:
- 🚗 Salon block - to the left of the steering column, under the instrument panel. Access is gained by removing the cover (latch or screw).
- 🔧 Engine compartment block — next to the battery, in a plastic box with a lid. Often labeled as
Fuse & Relay Box. - ⚡ Additional relays - can be located behind the glove compartment or under the center console (for example, a cooling fan relay).
On models with diesel engine YD22DDTi fuses for the system have been added in the engine compartment Common Rail and glow plugs. In petrol versions (QR20DE, QR25DE) there are none, but there are separate elements for controlling the ignition.

Diagram and decoding of the cabin unit fuses
Salon block Presage U30 contains fuses for most comfort and control systems. Below is the current diagram for the models 1998–2009, but check the version by the label on the block cover - sometimes the numbers may shift.
| Fuse no. | Denomination (A) | What is he responsible for? | Notes |
|---|---|---|---|
| 1 | 10A | Interior lighting, instrument lighting | Often burns out when installing LEDs |
| 5 | 15A | Cigarette lighter, 12V socket | On 2004+ models there may be a backup fuse No. 21 |
| 10 | 20A | Windshield wipers, washer | Check if the wipers are jammed |
| 15 | 7.5A | Audio system, navigation | On versions with Bose rating can be 10A |
| 20 | 10A | Engine control unit (ECU) | Replace only with the ignition off! |
Please note: on models with all-wheel drive (AWD) fuse No. 25 (10A) for the torque distribution system has been added to the cabin unit. Its absence is a common cause of error P1705 (solenoid malfunction Transfer Case).
How to check a fuse without a tester?
If you don’t have a multimeter at hand, you can visually inspect the fuse in the light - the blown thread will be broken. You can also replace a suspicious fuse with a known good one with the same rating (for example, from the cigarette lighter circuit).
Engine compartment fuse and relay box: what is where
Engine compartment block Presage U30 responsible for critical systems: ignition, fuel pump, cooling fans, etc. Its location is to the right of the battery (if you look in the direction of travel), in a black plastic box with a lid. The cover is usually marked with a diagram, but this often wears off over time.
Key elements of the engine compartment:
- ⚡ Fuse No. 3 (30A) - main fuse for the ignition circuit. If it burns out, the car will not start.
- ⛽ Fuse No. 7 (15A) — fuel pump. If the engine stalls while driving, check it first.
- 🔥 Relay No. 4 — cooling fan relay. On diesel versions, relay No. 6 is duplicated for the second fan.
- 💡 Fuse No. 11 (10A) — low beam (left headlight). No. 12 responds to the right headlight.
Important: on 2005+ models, relay No. 8 for the system appeared in the engine compartment VDC (stability control). Its malfunction may cause the indicator to blink SLIP on the dashboard.

How to properly check and replace a fuse
Replacing the fuse in Nissan Presage U30 - a simple procedure, but there are nuances that will help you avoid mistakes. Firstly, never replace a fuse with one of a different rating - this may lead to a fire in the wiring. Second, if the new fuse blows immediately, look for a short in the circuit.
Step by step instructions:
- Turn off the ignition and remove the negative terminal from the battery (required!).
- Locate the faulty fuse using the diagram (see previous sections).
- Remove it with special tweezers (usually attached to the block cover) or pliers.
- Install a new fuse same denomination.
- Connect the battery and check the system operation.
If the fuse blows again, do not rush to install a “bug” (wire). This could fry the wiring! It is better to contact an electrician to diagnose the circuit. Common reasons:
- 🔌 Short circuit in the wiring harness (for example, after repairs or an accident).
- 💦 Moisture getting into the fuse box (especially important for the interior unit).
- 🔋 Consumer malfunction (for example, windshield wiper motor or fuel pump).
If the fuse has blown for no apparent reason, check the circuit for current leakage. To do this, turn off all consumers (headlights, radio) and measure the current with a multimeter between the removed battery terminal and ground. The norm is no more than 50 mA.
Common problems and their solutions
Owners Nissan Presage U30 often encounter typical faults related to fuses. Here are the most common symptoms and how to eliminate them:
1. The cigarette lighter or 12V socket does not work
Reason: fuse No. 5 (15A) in the cabin unit or No. 21 (on models 2004+) has blown. Also check:
- 🔌 Socket contacts for oxidation (cleaned with alcohol).
- 🔋 Voltage at the socket terminals (should be 12V when the ignition is on).
2. Windshield wipers do not work
Culprits:
- 🚿 Fuse No. 10 (20A) in the interior block.
- 🔄 Windshield wiper relay (located in the engine compartment, usually next to fuse No. 10).
- 🔧 Wiper motor (checked by applying voltage directly).
3. The car does not start, the starter does not turn
Check procedure:
- Fuse No. 3 (30A) in the engine compartment.
- Starter relay (in the engine compartment, usually marked
ST). - Contacts on the starter solenoid relay (oxidation or breakage).
If the problem persists after replacing the fuse, always check the relay - it may stick or fail without visible signs.
Relay diagnostics: how to check without special tools
Relay in Nissan Presage U30 often cause malfunctions, but they can be checked without a tester. Most of the relays in this model are standard 4- or 5-pin (type OMRON G8P or similar). For diagnosis it is enough:
1. Winding continuity:
Connect the multimeter in resistance mode to the coil terminals (pins 85 and 86). Resistance must be within 50–120 Ohm. If it shows a break, the relay is faulty.
2. Checking contacts:
Apply 12V to pins 85 and 86 (for example, from a battery). There should be a click and contacts 30 and 87 will close. If there is no click or the contacts do not close, the relay needs to be replaced.
The most problematic relays in Presage U30:
- 🔥 Cooling fan relay (No. 4) - if there is a malfunction, the engine overheats.
- ⚡ Fuel pump relay (No. 7) - the car stalls while driving.
- 🚗 Starter relay (marked
ST) — the starter does not respond to turning the key.
⚠️ Attention: Do not try to disassemble the relays for repair - they are non-separable and filled with compound. Even if you manage to temporarily restore the contacts, such a relay will quickly fail again.

FAQ: Frequently asked questions about fuses Nissan Presage U30
Is it possible to install a fuse of a higher rating if it constantly blows?
No! This is extremely dangerous. A fuse is designed to protect a specific circuit. If it burns out, there is a problem (short circuit, overload). Installing a fuse with a larger rating may result in a fire. Instead:
- Check the circuit for short circuit.
- Make sure that the consumer (for example, a radio) does not consume more current than it should.
- Contact an auto electrician for diagnosis.
Which fuse controls the heated seats?
B Nissan Presage U30 Fuse No. 18 (15A) in the cabin unit is responsible for heated seats. If heating does not work, also check:
- Heating relay (located behind the glove compartment).
- Fuse No. 22 (10A) - it is responsible for the heating control unit.
- The condition of the heating elements in the seats (often burn out over time).
Why did all the devices stop working after replacing the fuse?
Most likely, you installed the wrong fuse or connected the battery terminals incorrectly. Also possible:
- The main fuse in the engine compartment has blown (No. 1, 80A).
- Malfunction of the fuse box due to contact oxidation.
- Ground break (check the fastening of the negative wire to the body).
Disconnect the battery for 5 minutes, then connect again - sometimes this will clear errors in the electrical system.
Where can I find a fuse diagram for my configuration?
The scheme may vary depending on the year of manufacture and market. Where to look for accurate information:
- 📄 Repair manual (For example, Nissan Presage U30 Service Manual - is freely available on the forums).
- 🖥️ Electronic catalogs: EPC Nissan (access by VIN), Autodata.
- 📌 Fuse box cover - it often contains a current diagram.
- 🤝 Owner forums: Nissan Club Russia, Drive2.ru (photos of blocks for different versions are posted there).
If you are not sure, take a photo of your block and compare it with the typical diagrams from this article.
Is it possible to clean fuse block contacts with WD-40?
WD-40 is not recommended for cleaning contacts because it leaves an oily film that attracts dust over time. Better to use:
- 🧴 Alcohol (isopropyl or ethyl) - removes oxides well.
- 🧽 Special contact cleaners (For example, Kontakt 60 or CRC QD Electronic Cleaner).
- 🔧 Fine grit sandpaper (1000–1200) — for mechanical cleaning of heavily oxidized contacts.
After cleaning, dry the block and apply a thin layer dielectric grease (For example, Liqui Moly Electronic-Spray) for protection against corrosion.
