Windshield washer motor on Nissan Almera G15 - it would seem a trifle, but its failure turns a trip in rain or snow into a real test. If when you press the washer lever you hear only silence or a buzzing sound without any fluid flowing, that is the problem. In 80% of cases, either the pump itself or clogged injectors are to blame - but today we’ll look at the first option.
Unlike many foreign cars, where replacement requires disassembling half of the front end, Almera G15 (2012–2019) the procedure is relatively simple. The main thing is to know the nuances: from choosing the original motor (article 28390-JM00A) until the connector is correctly connected, which often breaks during careless dismantling. This article contains a step-by-step algorithm with photos, typical mistakes and tips on how to save on repairs without losing quality.
Signs of a malfunctioning washer motor
The first sign is the absence of a jet of liquid when the washer is activated. But before you blame the pump, check:
- 🔋 Fuse F30 (10A) in the mounting block - it is responsible for the washer circuit. It rarely burns out, but does happen when there is a short circuit.
- 💧 Liquid level in the tank - sometimes the problem is trivial (especially if water was recently added, and not a special solution).
- 🔌 Connector on the motor — oxidation of contacts or poor contact simulates pump failure.
- 🌀 Injectors — clogging or icing blocks the flow of fluid even when the pump is running.
If everything is in order, but no fluid comes out, and you can hear a hum from the tank - the motor died from brush wear or the rotor jammed. Another symptom: the pump is working, but the liquid flows weakly or jerkily - this is a sign of wear on the impeller. In both cases replacement is required.
⚠️ Attention: Don't ignore a faulty washer! In the rain or when dirt gets on the glass, this is not just discomfort, but the risk of an accident due to poor visibility. Particularly critical for Almera G15 with its narrow nozzles - they clog faster with irregular use.
Which washer motor to choose for replacement
Original pump from Nissan has an article number 28390-JM00A (or 28390-JM000 for earlier versions). Cost - from 1,200 to 1,800 rubles, depending on the supplier. But there are proven analogues:
| Brand | Article | Price, ₽ | Features |
|---|---|---|---|
| Nissan (original) | 28390-JM00A |
1 200–1 800 | 1 year warranty, fully compatible |
| Valeo | 617003 |
800–1 100 | Quality close to original, popular in Europe |
| Febi | 28390 |
700–950 | Budget option, but lower resource |
| JP Group | 1283900100 |
650–850 | Counterfeits are common, check the packaging |
Advice: if you buy non-original, pay attention to contact polarity — for some analogues it may differ. Also check the package: the original kit includes a rubber gasket, which is often lost when dismantling the old motor.

Tools and preparation for replacement
To work you will need:
- 🔧 Flat and Phillips screwdrivers (preferably with a magnetic tip - the screws are small!).
- 🔨 Plastic puller or wide chisel for removing clips.
- 🧴 Silicone lubricant for rubber seals.
- 🔋 Multimeter (optional, for checking the circuit).
- 🧼 A rag and contact cleaner (e.g. WD-40 Contact Cleaner).
Before you start:
Drain the liquid from the tank (you can use a syringe or simply tilt the tank)
Disconnect the negative terminal of the battery
Prepare a container to drain remaining liquid
Take a photo of the location of the connectors and hoses -->
It is more convenient to carry out the work on an inspection hole or overpass, but if necessary, you can do without it - the main thing is to provide access to the washer reservoir from the bottom. On Almera G15 it is located on the right in the direction of travel, next to the front right wheel.
If the motor “buzzes” but does not pump, try tapping the reservoir with the handle of a screwdriver before replacing it - sometimes this will temporarily “reanimate” the jammed rotor. But this is only a delay; the pump still needs to be changed.
Step-by-step instructions for replacing the washer motor
Algorithm of actions:
- Removing the washer reservoir:
Unscrew the 3 screws securing the tank (two at the bottom and one at the top). Carefully disconnect the fluid supply hose to the injectors - it is held on by a plastic clamp. Do not pull the hose too hard to avoid breaking it!
- Removing the old motor:
Turn the pump counterclockwise (1/4 turn) and pull it out of the socket. Disconnect the power connector - the main thing here is not to break the latch. If the contacts are oxidized, clean them WD-40.
- Installing a new pump:
Check the rubber gasket - it should fit tightly. Insert the motor into the reservoir and turn clockwise until it clicks. Connect the connector (polarity is important!).
- Assembly and test:
Place the tank in place, secure it with screws and connect the hose. Fill with fluid and check the washer's operation. If the stream is weak, check the tightness of the connections.
The entire procedure takes 30–40 minutes. The hardest part is carefully removing the tank without breaking the plastic mounting clips. If you are not confident in your abilities, take photographs of each stage of disassembly.
⚠️ Attention: Do not use water instead of special washer fluid! In winter, this will lead to freezing of the system and repeated breakdown of the motor. The best option is a liquid with a freezing point no higher than -25°C.
What should I do if the motor does not work after replacement?
1. Check fuse F30 (10A) - it may have blown when connected.
2. Make sure that the connector is connected correctly (polarity!).
3. Test the circuit with a multimeter: there should be a resistance of ~0 Ohm from the connector to the fuse block.
4. If everything is in order, but the pump does not pump, the new motor may be defective (rare, but it happens).
Typical replacement mistakes and how to avoid them
Even experienced car owners sometimes make mistakes:
- 🔧 Tightening the tank screws - plastic is fragile, and cracks will lead to liquid leakage. Tighten to a maximum torque of 2 Nm.
- 💦 Ignoring the gasket — without it, the pump will suck in air and the stream will be weak.
- ⚡ Wrong polarity — if you confuse “+” and “-”, the motor will burn out the first time you turn it on. There is usually a marking on the connector.
- 🔄 Forget to check the injectors — even with a new pump, clogged nozzles will not produce a normal stream.
Another common problem is power wire break in case of careless dismantling. On Almera G15 The wiring runs along the spar and often frays. If the motor does not work after replacement, check the integrity of the wires from the connector to the fuse box.
If after replacing the motor the fluid flows in jerks, most likely there is air left in the system. Press the washer lever several times to bleed the system.
Prevention: how to extend the life of the washer motor
The average pump life is 100–150 thousand km, but with proper care it will last longer:
- 🌡️ Use quality liquid — cheap analogues contain aggressive additives that corrode rubber parts.
- ❄️ Drain the water in winter — if the car sleeps outside, dilute the liquid with alcohol (1:1) to prevent freezing.
- 🔄 Clean the injectors periodically - with a needle or compressed air. Clogged nozzles increase the load on the pump.
- 🔋 Check your contacts — oxidation leads to overheating of the motor. Clean the connector once a year WD-40.
Interesting fact: on Nissan Almera G15 with factory air conditioning, the washer reservoir has a slightly different form factor (part number 28391-JM00A). This does not affect the motor, but when purchasing a tank, take this feature into account.
FAQ: Frequently asked questions about replacing the washer motor
Is it possible to repair an old motor instead of buying a new one?
Theoretically, yes - if the problem is oxidized contacts or a clogged impeller. But in 90% of cases the electric motor fails, and repairs will cost more than buying a new pump. The exception is a jammed rotor: sometimes flushing helps WD-40 and manual scrolling.
What volume of fluid should be poured into the reservoir after replacement?
Washer reservoir volume per Almera G15 - 3.5 liters. Fill the liquid to the maximum mark (visible through translucent plastic). Do not add “to the brim” - when heated, the liquid expands.
What should I do if after replacement the motor works, but no fluid comes out?
Most likely the injectors or hoses are clogged. Disconnect the hose from the reservoir and check whether fluid flows when the washer is turned on. If yes, the problem is in the injectors (clean with a needle). If not, check the tightness of the connections or the presence of air in the system.
Is it possible to install a motor from another Nissan model?
Yes, but with reservations. Suitable pumps from Nissan Note (E11), Micra (K13) and Juke (F15) - they have identical connectors and fastenings. The main thing is the coincidence of the articles or geometry. For example, a motor from Tiida (C11) will not fit due to the different diameter of the seat.
Does the new motor need to be lubricated before installation?
No, this is not necessary - the pump is already lubricated at the factory. But if you are removing an old motor for a temporary repair, you can apply a drop of silicone grease to the rotor shaft to make it easier to move.
