Owners Nissan Qashqai first generation (J10) are often faced with the question: how to activate the headlight washers if the button on the lever does not work or the system shows no signs of life at all. The fact is that on some trim levels The headlight washer is not connected to the standard electrical system, although the injectors and reservoir are physically present. In other cases, the problem lies in a simple lack of fluid or clogged nozzles.
This article will help you understand all the nuances: from checking the presence of the system in your modification to step-by-step instructions for connection and diagnostics. We will consider three main scenarios: when the washer is present, but does not work; when it is not included in the package, but can be additionally installed; and how to operate the system correctly to avoid breakdowns. We will pay special attention hidden activation function via the diagnostic connector - this method works even on machines where the washer is not provided by the factory.
Checking for headlight washers in your Qashqai J10
Before you try to turn on the washer, make sure that it is installed on your car at all. On Nissan Qashqai J10 (2007–2013) headlight washer system included Tekna And Acenta Premium, but often it can be found on simpler versions as an option. Here's how to check:
- 🔍 Visual inspection: Lift the hood and locate the windshield washer reservoir. Next to it (usually on the right) there should be a second, smaller tank marked
HEADLAMP WASHERor justWASHER. If it is not there, the system is not installed. - 💡 Injectors on the bumper: Look at the front bumper under the headlights - there should be small round or rectangular nozzles (sometimes covered with plugs).
- 📋 Documentation: Check the service book or the equipment number sticker (usually on the driver's door pillar). Availability of code
B10orB11indicates the headlight washer.
If none of these signs are present, your Qashqai not equipped with the system from the factory. However, it can be additionally installed—we’ll talk about this in one of the following sections.
⚠️ Attention: On some restyled J10 models (2010–2013), the headlight washers could be replaced with rear window washer depending on the sales market. Don't confuse these systems!
- Yes, it works fine
- Yes, but doesn't work
- No system at all
- I don't know, I need to check
Where is the headlight washer switch located?
On Nissan Qashqai J10 The headlight washer control is integrated into the windshield wiper stalk (steering wheel paddle). To activate the system, follow these steps:
- Turn the ignition key to position
ON(the engine may not be started). - Pull the wiper lever on yourself (towards the steering wheel) and hold for 2-3 seconds. The sound of the pump should be heard.
- If the system is working properly, liquid will spray from the nozzles under the headlights, and after 1-2 seconds the low beam will turn on for drying.
If nothing happens, check:
- 🔋 The liquid level in the tank (should be between
MINAndMAX). - 🔌 Fuse
F37(10A) in the mounting block - it is responsible for the washer pump. - 💧 Clogging of nozzles (especially if the liquid does not splash, but the pump is humming).
☑️ Diagnosis of a non-working washer
On some versions Qashqai J10 (especially for European markets) the headlight washer is only activated when low beam. Try turning on the headlights before using the system.
Why the headlight washer does not work: top 5 reasons
If you are sure that the system is installed, but does not respond to pressing the lever, the problem may lie in one of the following components:
| Reason | Symptoms | Solution |
|---|---|---|
| Empty tank | The pump does not hum, no fluid flows | Add special liquid (not water!) |
| Frozen liquid | The pump hums, but no fluid flows | Warm up the reservoir or add antifreeze |
| Clogged injectors | The liquid barely oozes or splashes crookedly | Clean with a needle or compressed air |
| Fuse burned out | The pump does not respond, other washers work | Replace fuse F37 (10A) |
| Broken wiring | The pump does not hum, the fuse is intact | Test the circuit with a multimeter |
The most insidious problem is ground wire break pump It is located under the tank and often oxidizes. To check, disconnect the pump connector and apply direct power to it. +12V (for example, from a battery). If the pump starts working, look for an open circuit.
⚠️ Attention: Do not use ordinary water for headlight washer - in winter it will freeze and burst the reservoir or tubes. Use only special liquid with antifreeze (For example, Liqui Moly Scheiben-Frostschutz).
How to connect a headlight washer if it is not included in the package
If your Nissan Qashqai J10 is not equipped with headlight washers from the factory, but you want to install one, you will need:
- Purchase a set of injectors (item no.
26510-4M000for left and26510-4M001for the right one). - Buy a pump (
28397-4M000) and tank (28398-4M000) or use a standard windshield washer reservoir with an additional outlet. - Lay pipes from the tank to the injectors (diameter 4–5 mm).
- Connect the electrics through the relay to the button on the windshield wiper lever.

To activate the function via the standard button you will need flash body control module (BCM) or use a bypass switch. On some versions Qashqai J10 just connect the wires to the connector C104 (pin 1 - ground, pin 2 - signal to BCM).
Secret activation method through diagnostics
If your Qashqai is equipped with an OBD-II diagnostic connector, you can activate the headlight washers through the Nissan Consult-III or Launch X431 program. To do this:
1. Connect the scanner to the connector.
2. Select a block BCM (Body Control Module).
3. Go to menu Active Test → Headlamp Washer.
4. Activate the test - the pump should start working.
This method confirms the serviceability of the system and allows you to turn on the washer even without a steering column button.
Headlight washer maintenance: tips and tricks
To ensure your headlight washer lasts a long time, follow these rules:
- 🔄 Change the fluid every 6 months (even if the tank is not empty). Over time, it loses its cleaning properties.
- ☀️ Summer use a liquid with insect repellent additives (eg Sonax Insect Remover).
- ❄️ in winter check the antifreeze concentration - it should withstand up to
-25°C. - 🧹 Clean the injectors once a season with a soft brush or compressed air.
If the liquid starts to splash badly, try flush the system:
1. Drain the old fluid.
2. Pour in distilled water with the addition of vinegar (1:10).
3. Activate the washer several times to flush the tubes.
4. Drain the water and refill with fresh liquid.
If the nozzles spray crookedly, they can be adjusted with a needle or thin screwdriver. Rotate the nozzle clockwise to raise the jet and counterclockwise to lower the jet.
Common mistakes when using headlight washers
Many owners Nissan Qashqai J10 make mistakes that lead to system breakdown. Here are the most common:
- 🚫 Using water instead of liquid — leads to pump corrosion and freezing in winter.
- 🔥 Holding the lever for a long time (more than 5 seconds) - may burn the pump.
- 🛠️ Replacing injectors yourself without flushing the system — dirt from the old tubes will clog the new nozzles.
- ⚡ Ignoring the fuse - if F37 burns out often, look for a short circuit, and do not install a bug.
Another typical problem is hose mix-up when replacing the tank. The headlight washer and windshield washer are connected to different pumps, and if the tubes are mixed up, the fluid will go the wrong way. On the tank Qashqai J10 Usually there are tags:
- WINDSCREEN - for the windshield,
- HEADLAMP - for headlights.
If the headlight washer does not work after replacing the pump, check the polarity of the connection. The pump must rotate in the correct direction, otherwise the liquid will not flow into the tubes.
FAQ: Answers to frequently asked questions
Is it possible to use headlight washers without the headlights on?
On most Nissan Qashqai J10 the system works regardless of the light, but on some European versions activation is only possible when the low beam is on. This is done for safety - to prevent liquid from getting on hot lamps (risk of glass cracking).
What to do if the pump hums, but no liquid flows?
Most likely, the injectors or tubes are clogged. Disconnect the hose from the pump and check if the fluid flows directly. If yes, clean the injectors. If not, the problem is in the pump (the blades are worn out or the rotor is jammed).
What antifreeze should I add to headlight washer fluid?
Use special concentrates for washes (For example, Castrol Radicool or Mannol Scheiben Frostschutz). Do not add automotive antifreeze (such as Antifreeze) - it will foam and damage the pump. The optimal proportion for winter: 30–40% concentrate to 60–70% water.
Is it possible to turn off the headlight washers if they interfere?
Yes, you can physically turn off the pump (remove fuse F37) or remove the relay. However, this will result in an error on the instrument panel (if the system is diagnosed by the BCM). An alternative is to turn off the injectors and leave the pump connected, but this risks overheating the pump.
Where to buy original spare parts for headlight washers?
Original parts can be ordered by article number from official dealers Nissan or in trusted online stores (for example, Exist.ru, Autodoc). To save money, analogues from Febi (article 26510) or Hella (series 8KL 355 for injectors).
