Problem with a car's windshield cleaning system not working Nissan Almera often occurs suddenly, especially in rainy weather. When you press the wiper control lever and no fluid flows, the owner’s first thought is that it’s burnt out. fuse or failed on its own electric motor. However, before you run to the store for a new spare part, it is necessary to carry out proper diagnostics of the electrical circuit in order to eliminate false alarms and unnecessary expenses.
Most often, the reason lies precisely in the burnout of the protective element, since washer motor consumes significant current when starting. Owners Nissan Almera New and old generations face this problem regularly, and knowing the location of the fuse box can save you time and money. Let's look at a step-by-step algorithm of actions to quickly restore system functionality.
The device of the electrical washer circuit on Nissan Almera
Windshield and headlight washer system Nissan Almera operates according to a relatively simple circuit, where the key element of protection is a fuse. This component is installed in series with power cable, going from the battery to the pump. If a short circuit or overcurrent occurs, the fuse link burns out, breaking the circuit and preventing the wiring from catching fire.
It is important to understand that fuse does not work alone; it is part of a complex system that includes a relay (in some configurations), a switch on the lever, wiring and the electric motor. If you replace the fuse and it blows again, this is a sure sign that the problem is deeper - it may have stuck motor rotor or the wire insulation is damaged.
For correct diagnosis, you must have a power supply diagram on hand, since the location of the elements may differ depending on the year of manufacture and vehicle equipment. In some versions Nissan Almera A separate fuse for the rear washer is used if the body design provides one.
⚠️ Attention: Never try to replace a blown fuse with an element with a higher rating (amperage), even if it seems that “it’s more reliable.” This can lead to melting of the wiring and fire, since the design load on washer motor strictly limited.
Location and search for the fuse in the block
On most models Nissan Almera (especially G15 and previous generations) the fuse box is located in the engine compartment, to the left of the engine, closer to the battery. You will need to open the hood and find a black plastic box with a lid. On the inside of the lid there is usually a diagram showing all the elements, including WASHER MOTOR or FR WASH.
If you do not have a diagram on the cover or it has been erased, you need to rely on the markings on the block itself. Typically the washer fuse is rated 10A or 15A and is designated as F12, F13 or F15 depending on the version of the vehicle. You need to find the element responsible for supplying fluid to the glass, and not for operating the wipers, since these systems are often protected by different fuses.
- 🔍 Use a special tweezer clamp, which is usually attached to the block or in the passenger compartment, to remove the fuse.
- 🔦 Carefully inspect the metal jumper inside the transparent case - if it is torn, the element is burnt out.
- 🛠️ Check the contacts in the seat for oxidation or traces of plastic melting.
In some cases, access to fuses is difficult due to installed accessories or motor protection. In this case, you will have to temporarily dismantle the plastic covers to gain direct access to fuse box. Be sure to disconnect the battery before any electrical work if the job takes more than a few minutes.

Diagnostics of washer motor and relay
If you replace the fuse and the system still does not work, the problem may lie in the washer motor or in the control relay. Often owners Nissan Almera They are faced with the fact that the pump simply does not work, although the fuse is intact. In this case, it is necessary to check the presence of voltage at the motor connector when turning on the lever.
Use the multimeter in DC current mode. Connect the probes to the contacts of the connector going to the pump and ask an assistant to press the washer button. If there is voltage, but the motor is silent, then the problem is motor winding or impeller jamming. If there is no voltage, look for an open circuit or a faulty relay.
Pay special attention to the condition of the fluid reservoir. If the water level is critically low, the pump may run idle, overheat and burn out. Also check supply tubes for kinks or blockages, as excessive resistance can cause overload and trip the protection.
⚠️ Attention: In winter, liquids often freeze in supply hoses or the pump itself. It is strictly forbidden to turn on the motor in this state, as this is guaranteed to lead to its breakdown and blown fuse.
☑️ Diagnostics of the washer system
Replacing the fuse and checking functionality
Replacement process fuse on Nissan Almera It is quite simple and does not require special skills. Make sure you choose an element with exactly the same rating (eg 10A) as the old one. Visually, they may differ in color, which corresponds to the standard color coding: yellow - 20A, red - 10A, blue - 15A.
Insert the new fuse until it clicks, making sure it fits tightly and does not wobble. After this, close the unit cover and try to turn on the washer. If the system works, the problem is solved. If not, a more in-depth diagnosis of the wiring or replacement of the pump itself will be required.
- 📏 Always keep a set of spare fuses of different ratings in your glove compartment.
- 💧 Use only high-quality washer fluid suitable for the season to avoid crystallization.
- 🔧 Regularly clean the nozzles from dirt so as not to create unnecessary load on the pump.
After replacement, it is important to monitor the system for several days. If the fuse blows again, this indicates a serious problem that cannot be corrected by simply replacing the part. In this case, you need to contact an auto electrician to find short circuit to body or checking the integrity of the winding.
Why does the fuse blow repeatedly?
If the new fuse blows immediately or after a short time, this indicates a short circuit in the wiring or a jammed motor. Most often, the reason is mechanical damage to the insulation of the wire going to the pump, which rubs against the body or engine. It is also possible that the pump is jammed due to debris or ice getting inside the housing.
Troubleshooting common washer pump problems
Sometimes the problem is not in the electrical system, but in the mechanical part of the system. Pumps on Nissan Almera Over time they wear out and their effectiveness decreases. You may notice that the stream has become weaker, or the liquid flows in jerks. This may be a sign of wear and tear impellers or air entering the system due to leaking hoses.
To check the functionality of the pump, it can be temporarily disconnected from the tank and connected directly to the battery through a fuse. If, when voltage is applied, the pump hums and pumps water, then the problem is in the control circuit or button. If he is silent - electric motor to be replaced.
It is also worth checking the condition coarse filter, which is often built into the pump intake tube inside the reservoir. If it is clogged with dirt or sludge, the pump will be overloaded, causing the fuse to quickly blow. Flushing the tank and replacing the filter can solve the problem without replacing the motor itself.
Before the winter season, be sure to rinse the washer reservoir and replace the fluid with non-freezing fluid, even if it is still warm outside. Residual water may expand and damage the pump housing or hoses.
Specifics of Nissan Almera models of different generations
It is important to consider that the connection diagram and location of the fuses may vary depending on the generation of the car. On Nissan Almera Classic (N16) and the new model (G15) fuse blocks have a different layout. Classics often use a separate unit in the cabin, while new ones have a main unit under the hood with expanded functionality.
In some trim levels Nissan Almera with heated washer nozzles, the nozzle power supply circuit is also protected by a separate fuse. If your heating does not work, but the pump pumps, check this particular element. Ignoring this detail may result in the injectors remaining clogged with ice.
| Generation | Fuse rating | Location | Marking |
|---|---|---|---|
| Almera Classic (N16) | 10A | Block in the cabin (left) | F15 |
| Almera G15 (2012-2018) | 15A | Under the hood | F12 |
| Almera G15 (Restyling) | 10A | Under the hood | F14 |
| Almera (New platform) | 15A | Under the hood | F13 |
Please note that the data in the table is indicative and may vary depending on the country of assembly and year of manufacture. Always check the official owner's manual for your specific vehicle. On turbodiesel models, the washer circuit may have additional protection relays due to wiring features.
⚠️ Attention: When replacing the fuse with Nissan Almera With a start-stop system, make sure you use an element with the correct trip current, as standard fuses may not work correctly with the energy recovery system.
Proper diagnosis starts with checking the fuse, but if it blows repeatedly, be sure to look for a short or seized motor rather than changing the fuse over and over again.
