Wiper relay Nissan Note - a small but critical element of the electrical system on which the operation of the wipers depends. Its failure can lead to complete failure of the windshield wipers, which is especially dangerous in rainy weather. Owners Note (especially models E11 2006–2013 and E12 2013–2020) often encounter this problem due to oxidation of contacts, overheating or manufacturing defects.

In this article we will look at how to independently diagnose a relay malfunction, where it is located in the fuse box, what Article numbers of original and analog relays are suitable for replacement, and we will also give step-by-step instructions for dismantling and installation. We will separately focus on typical repair mistakes and connection nuances that will help avoid repeated breakdowns.

Where is the windshield wiper relay located? Nissan Note?

In most versions Nissan Note The wiper relay is located in fuse and relay mounting block, which is located inside the car - under the instrument panel on the driver's side. The exact location depends on the year of manufacture:

  • 🔧 E11 (2006–2013): the block is located to the left of the steering column, behind the plastic cover. The windshield wiper relay is usually labeled as R17 or R18 (depending on the configuration).
  • 🔧 E12 (2013–2020): the block has been moved closer to the center console, under the decorative trim. The relay can be marked as Wiper Relay or have a number K9.

To get to the block you will need:

  1. Disconnect the negative terminal of the battery (required!).
  2. Remove the plastic cover of the unit by prying it off with a screwdriver or flat tool.
  3. On the back of the cover there is usually a diagram of the location of the relays and fuses.
💡

Before dismantling the relay, take a photo of its location on the phone - this will help avoid confusion during reassembly, especially if there are several identical relays in the block.

If there is no diagram on the block cover, be guided by the color of the wire going to the wiper relay - usually this is blue with black stripe (food) and yellow (management). B Note The windshield wiper relay is often installed next to the heater fan or heated rear window relay.

Signs of a bad wiper relay

Relay malfunction manifests itself in different ways, but there is 5 Key Symptomsthat should alert you:

  • 🚨 The wipers only work in one mode (for example, only at high speed).
  • 🚨 The windshield wipers turn on spontaneously without pressing the lever.
  • 🚨 The wipers move jerkily or stop in an arbitrary position.
  • 🚨 When you turn on the wipers, you can hear the relay click, but the blades do not move.
  • 🚨 Wiper fuse (F30, 15A) constantly burns out.

It is important to distinguish a relay failure from a malfunction wiper motor or control lever. For example, if the wipers do not work at all and the relay clicks, the problem is most likely in the motor. If the relay does not make sounds when turned on, it is definitely out of order.

📊 What symptom of wiper malfunction have you encountered?
  • Wipers only work at one speed
  • The wipers move jerkily
  • The wipers don't turn on at all
  • Spontaneous switching on
  • Another option

For accurate diagnosis, you can use multimeter. Check the voltage at the relay contacts with the ignition on and the wiper lever activated. On contact 85 there must be 12V, on contact 86 — mass. If there is no voltage, the problem is in the wiring or switch.

Article numbers of original and analogue relays for Nissan Note

When replacing a windshield wiper relay, it is important to select compatible part. Original relays from Nissan They are highly reliable, but their price can reach 1500–2000 rubles. Analogs from trusted brands (Hella, Bosch, Valeo) will cost less, but do not always fit the connector.

Relay type Article Manufacturer Price, ₽ Notes
Original 25230-4M000 Nissan 1800–2200 Suitable for Note E11/E12, Micra K13
Analogue 4RA 007 593-331 Hella 800–1200 High quality, compatible with most Japanese cars
Analogue 0 332 014 150 Bosch 600–900 Budget option, possible problems with durability
Universal RU-505 Valeo 400–600 Requires connector testing before purchase

When choosing an analogue, pay attention to rated voltage (must be 12V) and contact type. Some universal relays have a different pin pitch, which will require modification of the connector.

⚠️ Attention! Relay from Nissan Almera N16 (25230-4M010) is similar in appearance, but has a different control scheme. Its installation on Note will lead to incorrect operation of the wipers in intermittent mode.

Step-by-step instructions for replacing the wiper relay

Replacing the windshield wiper relay with Nissan Note takes no more than 15 minutes, but requires care. Follow the instructions to avoid errors:

Disconnect the negative terminal of the battery

Remove the fuse box cover

Find the wiper relay by diagram or marking

Prepare a new relay and tweezers (if necessary) -->

  1. Disconnect negative battery terminal. This will prevent short circuits when working with electrical equipment.

  2. Remove the fuse box cover. On models Note E12 You may need a screwdriver to pry up the latches.

  3. Find the wiper relay. It is usually located in the bottom row of the block, next to the glass heating relay. There should be a diagram on the back of the cover.

  4. Carefully remove the old relay by pulling it up. If it's stuck, use tweezers or a flathead screwdriver to pry it out from the side.

  5. Install the new relay, making sure the contacts match. Press until you hear a characteristic click.

  6. Connect the battery and check the operation of the wipers in all modes.

If after replacement the wipers do not work correctly (for example, they do not stop in the down position), the problem may be motor or switch lever. In this case, additional diagnostics will be required.

What to do if the new relay does not work?

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

1. **Fuse F30 (15A)** - it could blow out due to a short circuit.

2. **Contacts in the block** - oxidation or contamination may interfere with signal transmission.

3. **Wiring** - open or short circuit in the relay control circuit (especially at the wiper motor connector).

4. **Switch lever** - its contacts may have worn out.

If the problem persists, have an electrician check the motor or body control module (BCM).

Typical mistakes when replacing a relay and how to avoid them

Even experienced car owners make mistakes when working with wiper relays. Here are the most common of them:

  • ⚡ Ignoring fuse check. Often, along with the relay, the fuse also burns out. F30. If it is not replaced, the new relay may immediately fail.
  • ⚡ Installing a relay from another model. For example, a relay from Nissan Qashqai (25230-4M020) is externally identical, but has a different operating logic.
  • ⚡ Wrong polarity. When installing a universal relay it is easy to confuse 85 And 86 contacts, which will lead to a short circuit.
  • ⚡ Forget to check the motor. If the relay clicks but the wipers don't move, the problem may be a worn out motor or a mechanical lock.
⚠️ Attention! After replacing the relay, be sure to check the operation of the wipers all modes: intermittent, low and high speed. If the wipers do not work correctly in one of the modes, it means the relay is incompatible or the problem is in the switch.

Another common mistake is using used relays. Even if it looks good on the outside, the contacts inside could have worn out, leading to another failure in a few months.

Diagnostics of the wiper motor: when the problem is not in the relay

If after replacing the relay the wipers still do not work, the cause may be windshield wiper motor. Its diagnosis includes several steps:

  1. Check the voltage at the motor connector with the ignition on and the wipers activated. On red wire there must be 12V, on black — mass.

  2. If there is voltage, but the motor does not work, remove it and check it mechanically. To do this, submit 12V directly from the battery to the motor contacts. If it does not spin, replacement is required.

  3. Check reduction gear. Often it wears out or breaks, blocking the movement of the wipers. Disassemble the motor and inspect the gear for chips.

Article number of the original wiper motor for Nissan Note E11/E12 — 25510-4M000. The cost of a new motor is from 3,500 to 5,000 rubles. Analogues from Denso or Valeo will cost less (2000–3000 ₽), but may have a shorter resource.

💡

If the wiper motor hums, but the blades do not move, the problem is in the mechanical part - for example, the linkage is jammed or the gearbox gear is broken. In this case, replacing the motor is inevitable.

Prevention of relay and wiper malfunctions

To extend the life of your windshield wiper relay and motor, follow these simple guidelines:

  • 🔄 Clean regularly fuse box contacts from oxidation (once every 6 months). Use a special contact spray (for example, CRC Contact Cleaner).
  • 🔄 Do not turn on the wipers if there is ice or snow on the glass. This creates excess load on the motor and relay.
  • 🔄 Check door seals. Moisture entering the fuse box is one of the main causes of contact corrosion.
  • 🔄 Use high-quality anti-freeze. Cheap fluids may contain aggressive additives that corrode motor seals.

B Nissan Note E12 (2013-2020) The wiper relay is especially sensitive to power surges. If fuses frequently blow in your car, install a voltage stabilizer or check the generator.

FAQ: Frequently asked questions about the wiper relay Nissan Note

Is it possible to drive without a wiper relay if you connect the motor directly?

Technically yes, but it's not safe. Directly, the motor will only operate at one speed, and intermittent mode will become impossible. In addition, the absence of a relay increases the risk of motor overheating and wiring fire.

Why did the new windshield wiper relay burn out quickly?

Most likely reasons:

  • Short circuit in motor circuit (check wiring).
  • Defective wiper switch (shorts contacts).
  • Using a relay with inappropriate characteristics (for example, 24V instead of 12V).

Before installing a new relay, be sure to test the circuit with a multimeter.

How to distinguish a relay failure from a motor failure?

The simplest way:

  1. Turn on the wipers and listen: if the relay clicks, but the motor does not work, the problem is in the motor or mechanics.
  2. If the relay does not click, check it with a multimeter or replace it with a known good one.

You can also submit 12V directly to the motor (bypassing the relay). If it works, the relay is to blame.

Where to buy an original relay for Nissan Note inexpensive?

Original relay 25230-4M000 can be found:

  • On AliExpress (price ~1200 ₽, but long wait).
  • In salvage parts stores (for example, Exist.ru or Autodoc).
  • From official dealers Nissan (more expensive, but quality guaranteed).

Before purchasing, check compatibility with your modification Note (E11 or E12).

Is it possible to repair a burnt out relay?

Theoretically yes, but it is impractical. The relay is a sealed unit with contacts, and its disassembly requires a special tool. Even if you manage to clean the contacts, the reliability of such a relay will be extremely low. It is much easier and safer to buy a new one.
