Owners Nissan X-Trail T32 (2014–2021 model years) sooner or later face the need to check or replace fuses. This could be due to headlights not working, power windows failing, problems with the audio system, or other electrical problems. However, find the correct fuse in fuse box It’s not always easy - especially if you don’t have a diagram or instructions at hand.
In this article we will look in detail at where the main and additional fuse blocks in Nissan X-Trail T32, we will provide a breakdown of the most popular fuses and relays, and also give practical advice on replacing them. We will pay special attention hidden fuse box under the hood, which many owners are not even aware of.
Where are the fuse boxes in the Nissan X-Trail T32?
B Nissan X-Trail T32 fuses and relays are distributed across three main blocks:
- 🚗 Salon block — located to the left of the steering column, behind the protective cover.
- 🔧 Engine compartment block — located next to the battery, under the plastic cover.
- 🔌 Additional block — hidden behind the glove compartment (in some trim levels).
The most frequently used block is salon. It is responsible for the main electrical circuits: lighting, power windows, cigarette lighter, audio system. The engine compartment contains fuses for powerful consumers: cooling fans, fuel pump, ABS system. The additional block (if any) usually duplicates part of the circuits or contains relays for optional equipment.
- Inside
- Under the hood
- Behind the glove compartment
- I don't know where to look
Interior fuse box: location and diagram
To access the cabin unit, follow these steps:
- Open the driver's door and sit in the seat.
- Look at the left side of the steering column - there you will see plastic cover with latches.
- Gently pry the cover with your fingers or a flathead screwdriver and remove it.
Under the cover there is a block with fuses and relays. There is usually a diagram with symbols on the inside of the cover. If it is missing or has been erased, use our table below.
☑️ What is needed to replace the fuse
| Fuse number | Amperage (A) | Purpose | Notes |
|---|---|---|---|
| 1 | 10 | Audio system, navigation | When burned out, the sound disappears, the screen does not turn on |
| 7 | 15 | Cigarette lighter, 12V socket | Often burns out when using powerful devices |
| 12 | 20 | Window lifters (driver's) | If only one glass does not work, check the motor |
| 18 | 10 | Low beam (left headlight) | If burnt out, check the lamp and contacts |
| 25 | 15 | Central lock | If it doesn’t work from the remote control, check the relay |
⚠️ Attention: If the fuse blows again after replacement, this indicates short circuit in the chain. In this case, it is necessary to diagnose the wiring or device that it protects.
Underhood fuse and relay box
The engine compartment unit is located next to the battery, under a black plastic cover. To remove it:
- Open the hood and lock it.
- Find the battery - the fuse box will be to the right of it (if you look in the direction of travel).
- Press the cover latches and lift it up.
This block contains high power fuses (30 to 100 A) and relays for critical systems:
- 🔥 Fuel pump (fuse 30A, relay K5)
- ❄️ Cooling fans (40A fuse, relays K1 and K2)
- 🚨 ABS system (fuse 10A, relay K7)
- 💡 Main relay (relay K3 - responsible for supplying power to the ECU)
What to do if the fuel pump fuse is blown?
If the fuel pump does not operate after replacing the fuse, check:
1. Condition of contacts in the block (oxidation, corrosion).
2. Wiring from the pump to the fuse box (possible chafing or breakage).
3. Relay K5 itself - sometimes it “sticks” and requires replacement.
If the problem persists, diagnose the pump itself (it may be jammed and creating an overload).
⚠️ Attention: When working with the engine compartment Be sure to disconnect the negative terminal of the battery. This will prevent a short circuit if the tool accidentally touches metal parts of the body.
Additional fuse box (behind the glove compartment)
Not all owners Nissan X-Trail T32 know that some trim levels have hidden fuse box behind the glove compartment. He is responsible for:
- 📱 Wireless charging (if installed)
- 🎵 Bose audio amplifier
- 🔦 Additional interior lighting
- 🚗 Electric trunk drive (in premium versions)
To access this block:
- Open the glove compartment and remove all contents.
- Press on the sides of the glove compartment to release the latches.
- Lower the glove compartment down and you will see a small plastic cover behind it.
- Remove the cover by pulling it towards you.
This block is usually installed mini fuses (5–15 A). Their decoding depends on the vehicle configuration. If you don't have a diagram, you can use color as a guide:
- 🟠 Orange - 5A
- 🔴 Red - 10A
- 🔵 Blue - 15A
- 🟢 Green - 20A
If you are not sure which fuse is responsible for a non-working device, use the elimination method: check the circuits one by one with a multimeter in the “continuity” mode (with the ignition off).
How to properly replace a fuse?
Replacing a fuse is a simple procedure, but there are several nuances that will help you avoid mistakes:
- Turn off the ignition and turn off the consumers (headlights, radio, etc.).
- Use plastic tweezers (usually included with the car) or tongs with insulated handles.
- Remove the faulty fuse and check it visually - the blown thread will be broken.
- Install a new fuse same denomination. Do not install a fuse with a large ampere under any circumstances!
If after replacement the fuse blows again, this indicates:
- 🔌 Short circuit in the chain.
- 🔋 Device malfunctions (for example, window lift motor).
- 🔌 Poor contact in the fuse box (oxidation, corrosion).
Never use "bugs" (homemade jumpers) instead of fuses! This can lead to a fire in the wiring and a fire in the vehicle.
Common problems and their causes
Some faults in Nissan X-Trail T32 are associated with fuses more often than others. Here are the most typical cases:
| Problem | Possible fuse | Additional reasons |
|---|---|---|
| Cigarette lighter doesn't work | F7 (15A, interior unit) | Oxidation of socket contacts, overload (for example, from a compressor) |
| Power windows don't work | F12 (20A, interior unit) | Motor malfunction, cable breakage, problems with the button |
| Headlights do not light (low/high beam) | F18 (10A) and F19 (10A, interior unit) | Burnt out lamps, oxidation of contacts in the headlight, malfunction of the steering column switch |
| Audio system doesn't work | F1 (10A, interior unit) | Firmware failure, antenna problems, amplifier failure (on Bose systems) |
| Cooling fan does not turn on | F3 (40A, engine compartment) | Relay malfunction, wiring break, temperature sensor failure |
If replacing the fuse does not solve the problem, it is recommended to check:
- 🔧 Relay status - sometimes it “sticks” or fails.
- 🔌 Contacts in the block - Oxidation or corrosion can disrupt the circuit.
- 📡 Wiring — frayed or melted wires require repair.
Tips for caring for fuse boxes
To ensure fuses last longer and electrical circuits operate stably, follow these recommendations:
- 🧹 Clean the blocks regularly from dust and dirt - use compressed air or a soft brush.
- 🔌 Check your contacts for oxidation. If necessary, clean them with alcohol or a special spray.
- 🔋 Avoid overload — do not connect devices with a power of more than 120 W to the cigarette lighter without an adapter.
- 🔧 Keep spare fuses different denominations in the glove compartment.
⚠️ Attention: If you frequently experience blown fuses, this could be a sign systemic problems with electrics. In this case, it is recommended to carry out a full diagnosis at a service center, since independent repairs without experience can aggravate the situation.
Check the condition of the fuses periodically (every 6–12 months), even if there are no visible problems. This will help prevent sudden electrical failures.
FAQ: Frequently asked questions about Nissan X-Trail T32 fuses
Is it possible to install a fuse of a higher rating if it constantly blows?
No, this is extremely dangerous! The fuse is designed for a certain amperage, and if you install a more powerful one, this can lead to overheating of wiring and even fire. If the fuse blows repeatedly, look for the cause (short circuit, faulty device).
How to check a fuse without a multimeter?
You can do this visually: the burnt thread inside the fuse will be broken. You can also replace a suspicious fuse with a known good one with the same rating - if the device works, that was the problem.
Where to buy fuses for X-Trail T32?
Fuses of standard ratings (5A, 10A, 15A, 20A) are sold at any auto store or gas station. For relays, it is better to contact the service Nissan or trusted online stores (for example, Exist.ru, Autodoc).
What should I do if the device does not work after replacing the fuse?
Check:
- The serviceability of the device itself (for example, a light bulb or motor).
- State of the relay (if it is in the circuit).
- Availability of power at the contacts of the fuse box (with a multimeter).
- Integrity of wiring from the unit to the device.
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 or special contact cleaners (for example, Kontakt 60).
