Right steering column switch in Nissan Almera G15 is a multifunctional unit that is responsible for controlling windshield wipers, washers and (depending on the configuration) cruise control. Despite its compact size, this element is subject to wear due to frequent use, especially on Russian roads with their salt, dirt and temperature changes. Owners Almeri G15 often encounter problems: from a banal failure of the wipers to short circuits in the circuit due to moisture.
In this article we will analyze in detail how the right steering column switch works, what symptoms indicate its malfunction, and whether it is possible to repair it yourself. We will place special emphasis on diagnostics without a scanner, selection of analogues and replacement nuances that are not described in the official manual. If you notice that the wipers are jerky, the washer does not turn on, or the icon lights up on the dashboard ESP (due to problems with cruise control), this information will be useful.
Design and functions of the right steering column switch
B Nissan Almera G15 right steering column switch (original article number - 25560-BM40A or 25560-BM40B depending on the year of manufacture) performs several tasks at once:
- 🔄 Wiper control: switch modes (intermittent, low/high speed, single stroke), as well as activate the rear wiper (if equipped).
- 💦 Control of windshield and rear window washers (in configurations with rear windshield washer).
- 🚗 Cruise control (in versions with this option): turn on/off, set speed, resume movement.
Structurally, the switch is a plastic case with a movable lever, inside of which there are contact groups and microswitches. The main problem is contact wear due to oxidation or mechanical abrasion. For example, with frequent use of the washer in winter, moisture penetrates the body and leads to corrosion of the tracks.
It's interesting that in Almere G15 The switch is connected to the body electronics control unit (BCM) through CAN bus. This means that the malfunction can manifest itself not only in the failure of the wipers, but also in errors in other systems - for example, ESP or dashboard lights.
- Every day
- 1-2 times a week
- Only in the rain
- There is no button nearby/not working
Signs of Trouble: When to Check the Switch
Symptoms of a broken right steering column switch on Nissan Almera G15 can be divided into three categories: mechanical, electrical and system. Here are the key signals:
- ⚡ The wipers work spontaneously or do not respond to mode switching.
- 💧 The washer does not turn on, although there is liquid in the tank and the pump is working.
- 🔥 Burning smell from under the steering wheel - a sign of burnt contacts inside the switch.
- ⚠️ Error
C1130(cruise control malfunction) on the dashboard. - 🔄 The lever moves with force or gets stuck in one position.
Critical point: If the wipers turn on randomly while driving, it may be caused by a short circuit in the switch. In this case, it is recommended to turn off the fuse F30 (15A) in the cabin unit until the malfunction is eliminated.
You can diagnose the problem without a scanner:
- Check fuses
F30(windshield wipers) andF28(washer). - Disconnect the switch connector (see diagram below) and check the voltage at the contacts
1 (+12V)And2 (mass)with the ignition on. - If there is voltage, but the wipers do not work, the problem is in the switch itself or the wiring.
How to test a switch with a multimeter?
Connect the probes to pins 3 and 5 of the connector (see the diagram in the "Electrical circuits" section). When switching modes, the resistance should change from 0 to 5 kOhm. Lack of change is a sign of a malfunction.
Electrical circuits and connector pinout
To diagnose and replace the right steering column switch with Nissan Almera G15 you need to know the pinout of its connector. Below is the diagram for the version without cruise control (most common option):
| Contact | Wire color | Purpose |
|---|---|---|
| 1 | Red | +12V (power) |
| 2 | Black | Weight |
| 3 | Green | Wiper intermittent signal |
| 4 | Yellow | Low speed wiper signal |
| 5 | Blue | Wiper speed signal |
| 6 | White | Washer control |
In versions with cruise control contacts are added 7 (gray) And 8 (purple) for signals SET/COAST And RES/ACC. Connection diagram to BCM implemented through CAN bus, so when replacing the switch it may be necessary flashing the block (valid for cars 2015–2018).
Important: Before disconnecting the connector, be sure to remove the terminal from the battery! Otherwise, the protection may work BCM, and you will have to reset the errors through the diagnostic scanner.
If, after replacing the switch, the wipers work in the opposite direction, check the polarity of connections of pins 3 and 4. In some non-original switches, it may be reversed.
Selection of spare parts: original vs analogues
Original right steering column switch for Nissan Almera G15 has articles:
25560-BM40A— without cruise control (until 2016).25560-BM40B— with cruise control (2016–2019).
The cost of the original in official dealers is from 8,000 to 12,000 rubles. However, there are proven analogues that will cost less:
| Brand | Article | Price, rub. | Notes |
|---|---|---|---|
| Febi | 25560 | 3 500–4 200 | Good quality but plastic is fragile |
| Sasic | 40025560 | 2 800–3 300 | Budget option, may require modification of contacts |
| Denso | 555-0103 | 5 000–6 500 | Reliable analogue, suitable for versions with cruise control |
When choosing an analogue, pay attention to:
- 🔧 Availability of cruise control (if it is included in your configuration).
- 🔌 Connector compatibility - some Chinese analogues have mixed up contacts.
- 📦 Completeness: the original comes with mounting clips, analogues may not have them.
⚠️ Attention: When purchasing a used switch, check it for contact oxidation! Even an apparently serviceable assembly may have microcracks on the board, which will lead to repeated failure.
Step-by-step replacement instructions
Replacing the right steering column switch with Nissan Almera G15 does not require special tools, but will require accuracy. Here is the algorithm of actions:
☑️ Preparation for replacement
- Removing the old switch:
- Using a flat blade screwdriver, pry the connector lock and disconnect it.
- Press the plastic tab at the base of the lever and pull the switch towards you.
- Installing a new one:
- Insert the new switch until it clicks (you should hear a detent).
- Connect the connector, making sure the pins are not bent.
- Check:
- Connect the battery and check the operation of the wipers in all modes.
- If you have cruise control, test it while driving (at speeds above 40 km/h).
⚠️ Attention: After replacement, you may need to reset errors in BCM via a diagnostic scanner (for example, Launch X431 or Delphi). If the wipers do not work correctly, try following the procedure "Steering Angle Sensor Reset".
Average replacement time - 20–30 minutes. If you have never worked with car electronics, it is better to contact a service center, as an incorrect connection can damage it. BCM.
When replacing the switch, do not use excessive force - the plastic latches break easily. If the lever does not come out, check whether the locking button at the base is released.
Switch Repair: When Possible
In most cases, the right steering column switch is on Nissan Almera G15 not repairable due to the sealed housing. However there are exceptions:
- 🔧 Oxidation of contacts - can be cleaned with alcohol or a special liquid Contact Cleaner.
- 🔩 Broken plastic lever — sometimes it can be glued with epoxy glue (but this is a temporary solution).
- 🔥 Burning tracks - in rare cases, soldering jumpers helps, but this requires skills in working with a soldering iron.
To disassemble the switch you will need:
- Carefully open the housing by prying it along the seam with a thin screwdriver.
- Clean the contacts with a cotton swab dipped in alcohol.
- Reassemble the housing, making sure all springs and retainer balls are in place.
Important: If chipped plastic or cracks on the board are found inside the switch, repair is pointless - the unit must be replaced. It is also not recommended to repair cruise control switches, since their circuit boards have a complex circuitry with a microcontroller.
What should I do if, after cleaning the contacts, the wipers operate jerkily?
This may indicate wear on the wiper motor brushes or a faulty relay. K30 in the fuse block. Check the voltage on the motor with the wipers on - it should be at least 11 V.
Frequent mistakes during diagnostics and repairs
Many owners Nissan Almera G15 make typical mistakes that lead to unnecessary expenses or aggravation of the problem. That's what can't do:
- 🚫 Ignore fuse check - often the problem lies in a burnt-out
F30, not in the switch. - 🚫 Buy the first analogue you come across — cheap Chinese switches may not match the pinout.
- 🚫 Lubricate the lever mechanism - this will lead to dust accumulation and accelerated wear.
- 🚫 Connect the switch with the ignition on - it can burn BCM.
Another common mistake is misdiagnosis. For example, if the washer does not work, the switch may not be at fault, but:
- Washer pump (
article number 25590-BM400). - Clogged injectors.
- Broken wire between the switch and the pump (often frays near the door hinge).
⚠️ Attention: If after replacing the switch the error message appears on the dashboard ESP, this may mean that the new node is not compatible with the firmware version BCM. In this case, adaptation via diagnostic equipment is required.
FAQ: Answers to frequently asked questions
Is it possible to drive with a faulty steering column switch?
Technically it is possible, but it is not safe. If the wipers or washer do not work, visibility in the rain deteriorates sharply. In addition, a short circuit in the switch can damage the BCM, which will cost many times more.
Why do the wipers work in the opposite direction after replacing the switch?
This means that contacts 3 And 4 (low/high speed) are not connected correctly. Check the connector pinout or swap the green and yellow wires.
How much does it cost to replace a switch at a service center?
The cost of working at an official dealer is from 1,500 to 2,500 rubles. In private services the price is lower: 800–1,200 rubles. However, if adaptation via a scanner is required, the cost may increase to 3,000 rubles.
Can the cruise control switch be repaired?
In most cases no. Cruise control switches have an integrated microcontroller that cannot be repaired. An exception is cleaning contacts during oxidation, but this is a temporary solution.
Where is the wiper relay located? Nissan Almera G15?
Wiper relay (K30) is located in the fuse box under the steering wheel. To get to it, you need to remove the plastic cover (snap off 3 clips). The relay is marked 72501-BM40A.
