<em>Nissan Almera G15</em> wiper switch: device, repair and typical breakdowns

Nissan Almera G15 is a popular sedan, but even it has its weaknesses. One of them is Steering wheel wiper switch, which over time begins to glitch, stick, or even fail. In this article, we will look at how the mechanism works, what malfunctions occur most often, and whether it is possible to repair it yourself without contacting a service center.

Problems with the switch manifest themselves in different ways: from random activation of the wipers to a complete lack of response to turning the lever. In some cases, the switch itself is to blame, in others it is the wiring or control unit. We will tell you in detail how diagnose the breakdown, we will select analogues of the original part and show you how much it costs to replace it in the service vs do-it-yourself repair.

If you are faced with the fact that the wipers Almera G15 work on their own or do not respond to commands, do not rush to change the entire steering column unit. Often the problem lies in oxidized contacts or worn tracks - they can be restored without great expense.

Wiper switch device Nissan Almera G15

The steering column wiper switch (aka combination switch) in Almera G15 combined with the turn signal and light control lever. This is a typical solution for most modern cars, but Nissan has its own characteristics:

The mechanism consists of:

• 🔧 Plastic case with clamps for attaching to the steering column.
• 🔄 Swivel arm with fixed positions (off, intermittent mode, 1st/2nd speed).
• 📶 Contact group - printed circuit board with tracks and spring-loaded contacts.
• 🔌 Power connector (usually 6- or 8-pin, depending on the year of manufacture).

Unlike earlier models Nissan, in Almera G15 (2013–2019) the wiper switch does not have a separate relay block - control is implemented via comfort block (BCM). This means that if the switch breaks, errors may appear in the on-board computer, for example, B2605 (wiper circuit malfunction).

Interesting fact: in versions for markets with cold climates (for example, Russia), the switch is equipped with an additional heating mode for the wiper rest zone, which is activated at temperatures below +5°C. This feature often becomes a source of confusion when the wipers suddenly turn on when the engine is started.

Typical faults and their causes

Wiper switch on Almera G15 fails for several reasons. Here are the most common symptoms and their possible sources:

Symptom	Probable Cause	Remedy
The wipers turn on by themselves	Oxidation of contacts or short circuit in the board	Cleaning contacts or replacing switch
Intermittent mode does not work	Worn resistor or tracks on the board	Board repair or block replacement
The lever moves slowly or sticks	Dirt or wear on the locking mechanism	Disassembly and lubrication of the mechanism
Wipers only work at maximum speed	Open circuit in switch or BCM	Diagnostics with a multimeter, replacement of a faulty element

One of the most insidious breakdowns - false positivewhen the wipers start working when you turn the steering wheel or turn on the turn signals. This is due to the fact that the switch contacts are located too close to the turn signal contacts, and when the insulation wears out, cross circuit.

⚠️ Attention: If the wipers turn on when you turn the key in the ignition, do not rush to blame the switch. In 30% of cases the problem lies in BCM block, which requires flashing or replacement.

Another common problem is spring mechanism wear inside the lever. Over time, the spring stretches and the switch does not return to its original position. In this case, only replacing the entire unit will help, since separate spare parts for repair are not supplied.

How to test a wiper switch with a multimeter

Before you buy a new switch, you should make sure that this is the problem. For this you will need multimeter and connector pinout diagram. Here are the step-by-step instructions:

1. Remove the plastic trim under the steering wheel (unscrew 2 screws Torx T20 and carefully remove the clips).

2. Disconnect the connector from the switch. On Almera G15 he usually gray with 6 or 8 contacts.

3. Set the multimeter to resistance test mode (200 Ohm).

4. Ring the contacts in different positions of the lever (see pinout table below).

Wiper switch connector pinout Nissan Almera G15 (6-pin version):

Contact	Purpose	Resistance in "Off" position
1	Power (+12V)	—
2	Ground (GND)	—
3	Intermittent mode	∞ (open)
4	1st speed	∞ (open)
5	2nd speed	∞ (open)
6	Feedback (for BCM)	0 Ohm (short to ground)

If, when switching modes, the resistance between the contacts does not change or shows 0 ohm in the "Off" position, it means the switch is faulty. Also check the integrity of the wires from the connector to the BCM - they often rub against the steering column.

Ring all contacts in the "Off" position. (should be ∞)

Check the resistance in each mode (must change)

Inspect the connector for oxidation or broken contacts

Step-by-step replacement of the wiper switch

If the diagnostics confirm that the switch is faulty, it will have to be replaced. On Almera G15 you can do this yourself in 30–40 minutes. You will need:

• 🔧 Screwdriver Torx T20.
• 🔨 Plastic spatulas for removing clips.
• 🔋 New switch (original or analogue).

Replacement instructions:

1. Disable negative battery terminal (required!).

2. Remove the lower plastic steering column trim (2 screws Torx T20 and 4 clips).

3. Disconnect the switch connector. Be careful - the retainer is fragile!

4. Remove the 2 screws securing the switch to the steering column.

5. Carefully remove the old switch and install the new one.

6. Reassemble everything in reverse order.

Important note: when installing a new switch, make sure that the lever is in the "Off" position.. Otherwise, the wipers may turn on immediately after connecting the battery, which will result in a short circuit if the wiper motor is blocked by ice or dirt.

⚠️ Attention: On some versions Almera G15 (2016–2017) required after switch replacement BCM error reset through a diagnostic scanner. Without this, the wipers may not work correctly.

The cost of the original switch (article 25540-JM00A) - about 3,500–4,500 rubles. Analogues (for example, from Febi or Blue Print) will cost 1,800–2,500 rubles. When purchasing, check compatibility using the VIN code - on restyled models (after 2018) the connector may be different.

Switch repair: when is it possible?

A complete replacement is not always required - in some cases the switch can be repaired. For example, if the problem is:

• 🔌 Oxidized contacts — they can be cleaned with an eraser or a special liquid.
• 🔄 Worn out paths on the board - they are restored with conductive glue.
• 🧴 Dirty mechanism - just disassemble and lubricate.

For repair you will need:

• Screwdriver PH00 to disassemble the case.
• Alcohol or contact cleaner (CRC Contact Cleaner).
• Conductive adhesive (Permatex or analogues).
• Silicone lubricant for plastic parts.

Step by step repair:

1. Disassemble the switch housing by carefully prying off the latches.

2. Clean the pins and tracks on the board. If there is damage, apply conductive glue.

3. Lubricate the spring mechanism and lever shafts with silicone grease.

4. Reassemble the housing, making sure all fasteners are in place.

Repair is justified if the switch is a rare modification or you want to save money. However, please note that after recovery no job guarantee - the problem may return in a few months.

What to do if after repair the wipers are unstable?

If after cleaning the contacts the wipers either work or not, check:

1. The quality of soldering/glue on the restored tracks.

2. The tightness of the contacts to the board (sometimes it helps to bend the springs).

3. Continuity of wires from switch to BCM.

If the problem persists, most likely the BCM itself or the wiper motor is faulty.

Common replacement mistakes and how to avoid them

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

1. Undisconnected battery. When replacing a switch, you may accidentally close the contacts, which will cause the fuse to burn out. F30 (10A) or BCM unit.

2. Incorrect lever installation. If the lever is not in the "Off" position, the wipers may turn on immediately after connecting the power, which can result in motor damage.

3. Ignoring BCM Errors. After replacement, you need to reset the errors through the diagnostic scanner, otherwise the wipers will not work correctly.

4. Buying an incompatible analogue. Switches for pre-restyling and restyling Almera G15 may differ in pinout.

To avoid problems, follow these tips:

• 🔋 Always disconnect the battery before use.
• 📸 Take photographs of the location of connectors and fasteners before removing.
• 🔍 Test the new switch with a multimeter before installation.
• 🔧 Use only high-quality analogues (for example, Febi or Hella).

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

• fuse F30 in the block under the hood.
• Wiper relay (K30 in the interior relay block).
• Wiring integrity from BCM to wiper motor.

FAQ: Frequently asked questions about the wiper switch Nissan Almera G15

Is it possible to drive if the wiper switch does not work?

Technically it is possible, but it is not safe. In rain or snow, visibility will be reduced, increasing the risk of accidents. In addition, if the wipers are constantly on, this leads to wear on the motor. A temporary solution is to connect the wipers directly to the button (if you have experience working with electrics).

Why do the wipers turn on by themselves when you turn the steering wheel?

This is a typical problem Almera G15, associated with the close proximity of the contacts of the wiper switch and turn indicators. When the insulation wears out, a short circuit occurs. The solution is to replace the switch or insulate the wires.

Which fuse controls the wipers?

B Almera G15 The fuse controls the wipers F30 (10A) in the block under the hood. Also check the relay K30 in the interior relay box (next to the fuses).

Is it possible to repair burnt tracks on a switch board?

Yes, this is possible using conductive adhesive (eg Permatex). However, the repair is temporary—the problem may return in 6–12 months. To be more reliable, it is better to replace the switch.

Do I need to reset errors after replacing the switch?

On most Almera G15 (especially 2016–2019) after replacement, errors must be reset via the diagnostic scanner. Without this, the BCM may not control the wipers correctly. In some cases, removing the battery terminal for 10 minutes helps.
