Nissan AD is a legendary SUV whose reliability has been tested by time, but even it is not immune to electrical problems. If your headlights stop working, your heater refuses to turn on, or your dashboard is flashing, the first thing you should check is fuses. In this article you will find complete fuse box diagrams for all modifications AD (including restyled versions), decoding of each element, as well as practical advice on diagnostics and replacement.
We won't just list the denominations, we'll explain how correctly identify a blown fuse, what tools are needed for replacement, and why you can’t use bugs. We will pay special attention a common mistake made by owners: installing overrated fuses, which leads to melted wiring and short circuits. If you are not confident in your abilities, there is an FAQ at the end of the article with answers to common questions.
Where are the fuse boxes located in Nissan AD
B Nissan AD (including versions Y61 And Y62) fuses are distributed according to three main blocks, and their location depends on the year of manufacture and configuration. Main installation locations:
- 🔧 Main unit in the cabin — under the dashboard on the driver's side (behind the protective cover). This is where the fuses for the lighting, audio system and climate control are located.
- ⚡ Block under the hood — next to the battery (in a plastic box). Responsible for high-voltage circuits: starter, generator, cooling fans.
- 🔌 Additional block — in the trunk or behind the rear trim (found in all-wheel drive versions). Controls the circuits of the rear lights, heated windows and trailer.
On cars produced after 2010, the unit under the hood can be moved closer to the windshield (to the left of the battery). To accurately determine your location, refer to cover marking - there is usually a diagram with fuse numbers on it.
- To the left of the battery
- To the right of the battery
- Next to the windshield
- I don't know, I didn't look
Important: on diesel versions AD (for example, with an engine ZD30) the unit under the hood may have additional relays for the high pressure fuel pump. They should not be confused with fuses - relays look like small black boxes with legs.
Explanation of the fuse diagram: main cabin unit
Main unit in the cabin Nissan AD contains fuses for most consumers. Below is a table with a breakdown for the most common modifications (2005–2015). Please note: denominations may vary depending on the configuration!
| Number | Denomination (A) | Purpose | Notes |
|---|---|---|---|
| 1 | 10 | Interior lighting, instrument lighting | Often burns out when installing LED lamps |
| 5 | 15 | Audio system, navigation | On restyled versions it may be 20 A |
| 10 | 20 | Window lifters | If the mechanism jams, it burns out instantly. |
| 15 | 7.5 | Instrument panel, speedometer | If it burns out, check the generator for overcharging. |
| 20 | 10 | Rear fog light | May be missing on export versions |
To access the block:
- Open the driver's door and remove the cover under the steering wheel (it is secured with two latches).
- Disconnect the unit backlight connector (if equipped) - it interferes with the removal of fuses.
- Use the tweezers that came with your car or a flathead screwdriver to remove the fuse.
If the fuse blows again after replacement, do not rush to install a new one - first check the circuit for a short circuit with a multimeter in the “continuity” mode.
Underhood fuse box: high voltage circuits
This unit is responsible for critical systems and its fuses are increased denominations (from 30 to 100 A). Here are located:
- 🔥 Generator main fuse (usually 80–100 A) - when it burns out, the car loses battery charge.
- ❄️ Cooling fan fuse (40 A) - if it burns out, the engine will overheat.
- 🚗 ABS and ESP chains (20–30 A) - if there is a malfunction, the lamp on the dashboard lights up.
- 🔋 Starter fuse (50 A) - if it is burned out, the engine will not start.
The special feature of this block is "maxi-fuse" fuses (larger than standard). To remove them you will need a special puller (sometimes included with the car). If there is no puller, you can carefully pry the fuse with a screwdriver, but do not use excessive force — the plastic body of the unit is fragile.
⚠️ Attention: Never replace fuses under the hood by eye. For example, installing 60-A instead of 40-A in a fan circuit may result in a wiring fire. Always check the diagram on the unit cover!
What should I do if the starter fuse blows again?
This indicates a short circuit in the starter circuit or a malfunction of the solenoid relay. Check:
1. Condition of the wires from the battery to the starter (are there any melts).
2. Contacts on the solenoid relay - they often oxidize.
3. The relay itself (can be temporarily replaced with a known good one).
If the problem persists, the starter needs to be diagnosed at a stand.
Additional fuse box: rear of vehicle
This block is not found on all versions Nissan AD, but if your car is equipped heated rear window, tow hitch or rear air conditioning, then he is. Location:
- 📦 In the trunk under the trim (left or right).
- 🚙 Behind the rear panel (in all-wheel drive versions).
- 🔌 Near the trailer socket (if installed).
Typical fuses for this block:
| Number | Denomination (A) | Purpose |
|---|---|---|
| 1 | 20 | Heated rear window |
| 2 | 15 | Rear fog light |
| 3 | 10 | Trailer socket (signal circuits) |
| 4 | 30 | Trailer socket (power circuit) |
If your rear window heating is not working, first check:

How to check and replace a fuse: step-by-step instructions
To diagnose and replace fuses you will need:
- 🔧 Tweezers (it is better to use the original one that came with the car).
- 🔦 Flashlight - blocks are often located in poorly lit areas.
- 📊 Multimeter (for checking circuits).
- 🔄 A set of spare fuses (with ratings of 5, 10, 15, 20, 25, 30 A).
Step by step steps:
- Turn off the ignition and remove the battery terminal (negative).
- Locate the faulty fuse using the diagram (see previous sections).
- Remove it with tweezers and inspect:
- 🔥 Blown fuse has a broken thread inside.
- ⚡ Melted body indicates a short circuit.
⚠️ Attention: If the new fuse blows immediately, do not repeat replacement - this is a sign of a serious malfunction (short circuit or circuit overload). In this case, electrical diagnostics are required.
The use of "bugs" (wires instead of fuses) is strictly prohibited! This can lead to melted wiring and even a fire.
Typical problems and their solutions
Owners Nissan AD often encounter repeated faults related to fuses. Let's look at the most common ones:
- 💡 The interior lighting fuse blows (10 A) - LED lamps with incorrect polarity or a short circuit in the lampshade are usually to blame. Solution: Replace the stock bulbs or check the circuit.
- 🚗 The cigarette lighter fuse burns out (15–20 A) - most often due to the connection of powerful devices (compressors, inverters). Solution: Use a power strip with a separate fuse.
- ❄️ Cooling fan fuse (40 A) blows in hot weather — check the fan itself for jamming and the relay. The temperature sensor may be faulty.
- 🔊 Audio system does not turn on (15 A fuse) — if replacement does not help, check the wiring to the radio (wires under the dashboard often fray).
Particular attention should be paid ABS fuse (usually 10–15 A). If it burns out, a light comes on on the dashboard ABS, and the system turns off. Reasons:
- Damaged wheel hub sensor.
- Short circuit in the wiring harness to the ABS unit.
- Faulty ABS pump (requires diagnostics at a service station).
For a temporary solution, you can remove the fuse and drive without ABS, but it's dangerous - braking distance will increase, especially on slippery roads.
FAQ: Frequently asked questions about fuses Nissan AD
Is it possible to use a fuse with a higher rating if the standard one blows?
No! Increasing the rating will cause the wiring to melt. If the fuse burns out repeatedly, look for the cause: a short circuit, a faulty consumer (for example, a window lift motor) or a circuit overload (for example, when connecting a powerful compressor to the cigarette lighter).
Where to buy fuses for Nissan AD?
Original fuses can be found at dealerships (the part number depends on the rating, e.g. 28510-4M000 for 10 A). Analogues: Bosch, Hella, Valeo. The main thing is that the denomination and type (standard or “maxi”) match.
How to check a fuse without a multimeter?
Visually: a burnt thread inside the housing will be torn. You can also use the “replacement method” - install a known-good fuse of the same rating. If the circuit worked, the old fuse was bad.
Why does the device not work after replacing the fuse?
Possible reasons:
- Wrong rating (for example, they put 10 A instead of 15 A).
- The device itself is faulty (for example, the light bulb in the headlight has burned out).
- The problem is in the relay (it may click, but not close the contacts).
- Broken wire in the circuit (check with a multimeter).
How to protect fuses from frequent blowing?
Tips:
- Do not connect powerful devices (for example, refrigerators) through the cigarette lighter - use a separate socket with a fuse.
- Periodically check the condition of the contacts in the fuse boxes (oxidation increases resistance).
- When installing additional equipment (for example, a winch), lay separate wires with a fuse近and to the battery.
