Nissan AD with body 11th generation (1995–2000) - a legendary sedan that is still in use on the roads of the CIS. Like any car with a significant mileage, it requires attention to electrics. Fuses are the “weak link” that protects the on-board network from short circuits and overloads. But when they burn out, the driver is faced with inoperative headlights, power windows, or even engine failure.

In this article you will find detailed fuse layout diagram for Nissan AD (B14), an explanation of their purpose, as well as step-by-step instructions for replacement. We will look at where the main blocks are located, how to identify a blown fuse without a tester, and what to do if the problem remains after replacement. We will pay special attention to typical mistakes that owners make when working with electrical equipment.

Where are the fuse blocks located in Nissan AD (11 body)

B Nissan AD with body 11th generation There are two main fuse blocks:

  • 🔧 Main unit — located under the hood, next to the battery (driver's side). It is protected by a plastic cover with the inscription FUSE.
  • 🚗 Additional block — located in the cabin, under the instrument panel on the driver’s side. To gain access, you need to unscrew the two screws securing the plastic cover.

Also found in some modifications third block — it is installed in the trunk, next to the audio system amplifier (if the car is equipped with premium acoustics). However, it is usually not included in basic configurations.

Important: Don't confuse fuses with relays! In the same block under the hood there are relays that are responsible for the operation of the cooling fan, starter and other components. They look like small boxes with legs and are marked with letters R (For example, R1, R2).

Diagram and decoding of fuses Nissan AD (11 body)

Below is a table with the assignment of fuses for Nissan AD (B14) 1995–2000. Please note that depending on the year of manufacture and configuration location and value may vary slightly.

Fuse no. Denomination (A) Purpose Symptoms of a problem
F1 10 Side light (left side), license plate light Left side lights or license plate lights do not light up
F5 15 Low beam (right headlight), reverse lamp Right low beam or reverse gear does not work
F10 20 Power windows (all), central locking Windows or door locks do not work
F15 10 Cigarette lighter, audio system Cigarette lighter or radio does not work
F20 30 Heater fan, heated rear window The heater does not blow or the rear window does not heat

Attention! fuse F25 (15A) is responsible for the operation of the engine ECU. If it burns out, the car may stall or not start. Replacing it requires special care - never install a fuse of a higher rating!

The complete diagram for your modification can be found at back of the fuse box cover or in the instruction manual. If you don't have a manual, download it in PDF according to the model Nissan AD (B14) with motor rating GA14DE or GA16DE.

📊 How often do you check the fuses in your Nissan AD?
  • Only when something breaks
  • Once every six months
  • Once a year
  • Never checked

How to identify a blown fuse without a tester

If you don't have a multimeter handy, visual inspection will help identify the problem. Follow this algorithm:

  1. Turn off the ignition and disconnect the negative terminal of the battery.
  2. Remove the fuse box cover (it is secured with latches or screws).
  3. Remove the fuse with tweezers (usually included with the machine) or pliers.
  4. Look at the light wire bridge inside the fuse:
    • ✅ If the wire is intact, the fuse is working.
    • ❌ If the wire is burned out (broken or melted) - replacement is required.

If the fuse is apparently intact, but suspicions remain, you can check it for a spark:

  • 🔌 Insert the fuse into the socket and turn on the problematic device (for example, headlights).
  • 👀 Touch the metal contacts of the fuse with a screwdriver. If there is sparking - it is faulty.

Important! Never test fuses with your tongue or your fingers - this is dangerous! The voltage in the on-board network can reach 12–14 V, which is fraught with electric shock.

💡

If the fuse frequently blows after replacement, look for short circuit in the chain. For example, exposed wires under the panel or oxidized contacts.

Step-by-step instructions for replacing fuses

Replacing the fuse in Nissan AD - a simple procedure, but requiring accuracy. Follow the instructions to avoid damaging the unit or wiring:

Disconnect the negative terminal of the battery|Find the faulty fuse according to the diagram|Prepare a new fuse of the same rating|Use tweezers to remove|Check the operation of the circuit after replacement-->

  1. Turn off the power. Remove the negative terminal from the battery to avoid short circuit.
  2. Locate the problematic fuse. Use the diagram from the previous section or inspect the unit cover.
  3. Remove the blown fuse. Take plastic tweezers (usually found in the block) and carefully pull it out. If you don't have tweezers, use small pliers, but don't use too much force—the contacts are fragile!
  4. Install a new fuse. He must be same denomination (for example, if it burned 15A, just put 15A!). Installing a larger fuse will result in fire in the wiring.
  5. Check the operation of the circuit. Connect the battery terminal and turn on the problematic device (headlights, window lift, etc.). If it does not work, look for a break in the wiring or a malfunction in the device itself.

If after replacement the fuse blows again, this is a signal about serious problem:

  • 🔥 Short circuit in the circuit (check the wires for exposed areas).
  • 🔌 Consumer malfunction (for example, a jammed window lifter motor).
  • 🔋 Problems with ground (oxidized contacts on the body).
What to do if the fuse is stuck to the contacts?

If the fuse cannot be removed from the socket, do not try to pull it out by force - this will damage the contacts of the block. Instead:

1. Treat the socket with WD-40 or similar lubricant.

2. Wait 5-10 minutes for the liquid to take effect.

3. Gently rock the fuse from side to side with tweezers.

4. If that doesn’t help, use a thin screwdriver to pry it out from the side.

Typical mistakes when working with fuses

Even experienced car owners sometimes make mistakes that lead to electrical damage or fire. Here are the most common of them:

⚠️ Attention! Never replace a fuse with a “bug” (wire or foil). This may lead to fire in the cabin or failure of the engine ECU. B Nissan AD The injection control circuit is especially vulnerable - its overload will result in costly repairs.
  • 🔧 Using a fuse of a different rating. For example, instead of 10A put 15A, thinking that “it’s more reliable this way.” This actually causes the wiring to melt.
  • 🔌 Ignoring the cause of burnout. If the fuse blows repeatedly, you need to look for short circuit, and not change it again.
  • 🔍 Checking live fuses. Always disconnect the battery before working - even a small current can cause a spark and melt the contacts.
  • 📄 Lost fuse circuit. Many owners Nissan AD they throw away the block cover or manual, and then wonder which fuse is responsible for what. Take a photo of the diagram on the phone!

Another common problem is contact oxidation in the fuse block. If you notice green deposits on metal parts, clean them WD-40 or fine sandpaper. This will restore reliable contact and prevent spontaneous blowing of fuses.

Frequently asked questions about Nissan AD fuses (11 body)

Why does fuse F10 (power windows) often blow in my Nissan AD?

This problem is typical for Nissan AD with high mileage. Reasons:

  • Wear and tear of the window lift motors (they begin to consume more current).
  • Oxidation of contacts in door wires (especially in the corrugation between the body and the door).
  • The window lifter mechanism is stuck (the guides need to be lubricated).

Solution: check the motors and wiring, clean the contacts. If the problem remains, replace the motors with new ones (part number for the front ones: 80850-4M000).

Is it possible to install a 20A fuse instead of 15A if it constantly blows?

No! Increasing the fuse rating will result in:

  • Melting of wiring (wires are designed for a certain current).
  • Failure of the device that protects the fuse (for example, a computer or audio system).
  • Fire in the cabin (in extreme cases).

If the fuse blows frequently, look for short circuit or a fault in the circuit.

Where is the cigarette lighter fuse located in Nissan AD?

B Nissan AD (11 body) The cigarette lighter fuse is F15 (10A) in salon block (under the instrument panel). If the cigarette lighter does not work after replacement, check:

  • Continuity of the wire from the cigarette lighter to the fuse box.
  • Ground contact (often oxidizes under the torpedo).
  • The cigarette lighter itself sometimes burns out the coil inside.
How to test a relay in a Nissan AD without a multimeter?

If you don’t have a tester at hand, you can check the relay “by ear” and “by replacement”:

  1. Remove the suspect relay from the block.
  2. Shake it - if something rattles inside, it means the contacts have come off.
  3. Place a known working relay (for example, from a fan circuit) in place of the one being tested. If the device works, the relay is faulty.

For Nissan AD standard type relays are suitable 90.3747-10 (4 pins) or 90.3747-11 (5 contacts).

What should I do if the headlights do not work after replacing the fuse?

If the fuse is intact but the headlights do not light, check:

  • Lamps (they could burn out at the same time).
  • Light relay (in the unit under the hood, usually R3 or R4).
  • Light switch on the steering column (contacts often oxidize).
  • Wiring from the fuse box to the headlights (look for breaks or melts).

B Nissan AD there is also a problem with oxidation of connectors on the headlight - clean them and lubricate them with contact lubricant.
