<em>Nissan Qashqai J10</em> wiper relay: where is it located, how to check and replace

Wiper relay on Nissan Qashqai J10 (2006–2013) is one of those elements that often fails after 100–150 thousand kilometers. Owners are faced with problems: wipers only work in one mode, do not turn off, move jerkily, or fail altogether. The reason in 80% of cases lies in the relay K25 (or K30 depending on the configuration), which is responsible for controlling the windshield wiper motor.

In this article we will analyze exact symptoms of a relay malfunction, its location in the fuse block, diagnostic methods with a multimeter and step-by-step replacement. We will also provide article numbers of original and compatible relays, a connection diagram and answers to frequently asked questions. The information is relevant for all modifications Qashqai J10 (gasoline/diesel, front/all wheel drive).

Where is the wiper relay located on Nissan Qashqai J10?

The windshield wiper relay is located in main fuse and relay box, which is located inside the car - under the instrument panel on the driver's side. To access:

1. Open the driver's door and remove decorative cover under the steering wheel (it is secured with latches).
2. Find a black plastic block with a cover on which the fuse diagram is printed.
3. Remove the cover by pulling it towards you.

The wiper relay is labeled as K25 (or K30 in some versions). It is located in upper right corner of the block, next to the cooling fan relay (K26). For convenience, below is a photograph of the block with notes:

The image shows that the K25 relay has a blue or black housing with white markings. Nearby are fuses F30 (10A) and F31 (20A), which are responsible for the windshield wiper circuits.

⚠️ Attention: On diesel versions Qashqai J10 (for example, with an engine 1.5 dCi) the relay may have a different index - K30. Check the location according to the diagram on the back of the block cover!

Signs of a bad wiper relay

Wiper relay on Nissan Qashqai J10 fails gradually or suddenly. Here main symptoms, indicating its malfunction:

• 🔄 The wipers only work when one mode (for example, only at high speed).
• ⚡ Stopped working intermittent modes (the first and second speeds are turned on, but there is no pause).
• 🛑 Wipers don't stop in its original position after switching off.
• 🔊Audible relay clicks under the dash, but the wipers don't move.
• 🔥 Fuse F30 (10A) burns again after replacement.

If the wipers move jerkily or slowly, the problem may lie in windshield wiper motor or mechanical part (for example, wear of gears of a gearbox). In this case, the relay is most likely working properly.

How to check the wiper relay with a multimeter?

Before replacing the relay K25/K30 you need to make sure that this is where the problem lies. For this you will need multimeter (or control lamp) and a screwdriver. Check procedure:

1. Remove the relay from the unit by pulling it up (do not use excessive force - the contacts are fragile!).
2. Ring the winding: connect the multimeter probes to the terminals 85 And 86 (see diagram below). Resistance must be within 50–120 Ohm.
3. Check your contacts: when 12V is applied to 85 And 86 there should be a click and between 30 And 87 conductivity will appear.

The relay contact diagram is standard for Nissan:

Contact	Purpose	Wire Color (Typical)
30	Common plus (constant voltage)	Red or orange
85	Control minus (from switch)	Black/white
86	Plus after ignition switch	Yellow or green
87	Output to wiper motor	Blue or gray

If the relay does not click when voltage is applied or the winding resistance is equal 0 (short circuit) or ∞ (break), it needs to be replaced. Also check fuse F30 (10A) - it often burns out during a short circuit in the relay circuit.

Article numbers of the original relay and analogues

Original wiper relay for Nissan Qashqai J10 has an article number 25230-4M000 (or 25230-4M00A in new revisions). However, it can be replaced with analogues from other manufacturers, which are cheaper but not inferior in quality. Below is a table of compatible relays:

Manufacturer	Article	Price (approximate), ₽	Notes
Nissan (original)	25230-4M000	1 200–1 800	Best quality but high price
Bosch	0 332 019 150	400–600	Reliable analogue, fits without modifications
Hella	4RA 003 507-251	500–700	Good quality, long service life
Valeo	402008	350–500	Budget option, there may be complaints about durability

When purchasing an analogue, pay attention to relay type: it must be 12V, with 4 contacts (not 5!) and normally open contacts (NO — Normally Open). Relay from Renault (For example, 8200841850) are also suitable because Qashqai J10 built on a platform Renault-Nissan.

Step-by-step instructions for replacing the wiper relay

Relay replacement K25/K30 on Nissan Qashqai J10 takes no more than 10 minutes. You will need:

• 🔧 Flat screwdriver (for removing the block cover).
• 🔍 Flashlight (for ease of inspection).
• 🔋 New relay (check the article number!).

Procedure:

⚠️ Attention: If after replacing the relay the wipers still do not work, check:

• 🔌 fuse F30 (10A) — it could burn out during a short circuit.
• 🔧 Contact status in the block (oxidation or burning).
• 🔄 Wiper switch on the steering column (a common cause is oxidation of the tracks).

If the problem persists, it may be faulty windshield wiper motor or electrical wiring. In this case, diagnostics using a scanner (for example, Launch X431) or checking the voltage at the motor connector.

Common mistakes when replacing relays and how to avoid them

Many owners Nissan Qashqai J10 make mistakes that lead to repeated breakdowns or even failure of the wiper motor. Here are the most common:

1. Installing a relay with different characteristics. For example, a relay with 5 contacts or 24V. This leads to short circuit and fuse blown F30.
2. Ignoring oxidized contacts. If the fuse box shows signs of corrosion, the new relay will quickly fail. Clean your contacts alcohol solution or special lubricant (for example, Kontakt 60).
3. Failure to check fuse. If F30 burned out, its replacement is required! Operation without a fuse may result in fire in the wiring.

Another common mistake is relay mix-up. For example, instead of K25 (windshield wipers) install K26 (fan). They are similar in appearance, but have different operating logic. Always check with markings on the block cover!

What should I do if, after replacing the relay, the wipers do not work correctly?

If the wipers move jerkily or do not stop in their original position, the problem may be motor or drive mechanism. Check:

• The condition of the gears of the motor gearbox (they often wear out on runs over 150 thousand km).
• Integrity of the wiper drive rods and levers (corrosion or deformation).
• Voltage at the motor connector (should be 12V when the ignition is on).

In some cases it helps calibration: Turn on the wipers, wait until they stop in the extreme position and turn off the ignition for 10 seconds.

Preventing wiper relay malfunctions

To ensure that the windshield wiper relay is on Nissan Qashqai J10 last longer, follow these recommendations:

• 💧 Use a quality glass cleaner. Cheap products with a high alcohol content or aggressive additives accelerate wear of the motor, which increases the load on the relay.
• ❄️ Do not turn on the wipers when the glass is frozen. This leads to overload of the motor and relay. Clean the ice with a scraper first.
• 🔧 Clean the fuse box contacts periodically. Oxidation impairs conductivity and can cause false relay activations.
• 🔄 Do not keep the wipers on for a long time without any liquid.. Dry running increases friction and current consumption.

It is also worth paying attention to condition of wiper blades. Worn brushes create additional load on the motor, which indirectly affects the life of the relay. The optimal brush replacement interval is every 6–12 months.

FAQ: Frequently asked questions about wiper relays Nissan Qashqai J10

Is it possible to drive without the wiper relay if it is burned out?

No, it's dangerous. Without a relay, the wipers will either not work at all or will be on constantly (if the contacts are closed). In the second case, this will lead to battery discharge and possible overheating of the motor. Also driving without working windshield wipers prohibited by traffic rules (fine 500 ₽ under Article 12.5 of the Administrative Code).

Why does a new relay burn out quickly?

If the new relay fails within a week, the reasons may be the following:

• Short circuit in wiring (check the circuit from the relay to the motor).
• Defective wiper motor (increased current consumption).
• Poor contact in relay connector (oxidation or burning).

It is recommended to carry out complete circuit diagnostics multimeter.

Can the wiper relay be repaired?

Theoretically yes, but impractical. A relay is a sealed unit with contacts, and disassembling it often leads to damage to the housing. Cost of a new relay (Bosch or Hella) - from 400 ₽, while repairs will cost more and do not guarantee durability. Exception - cleaning contacts (if the relay clicks, but there is no conductivity between 30 And 87).

Where else is the same relay used in Qashqai J10?

Wiper relay (25230-4M000) is identical to the relays of the following systems:

• Heater fan (K26).
• Heated rear window (K28).
• Low beam headlights (in some trim levels).

This means that in an emergency you can temporarily swap relays for checking.

Do I need to remove the battery when replacing the relay?

Preferably disconnect the negative terminal of the batteryto avoid short circuit when removing/installing the relay. However, if you act carefully, you can do without it. The main thing is do not touch the relay contacts and metal parts of the body at the same time.
