Where is the cabin filter located? Nissan Sunny?

In most cars Nissan The cabin filter is located behind the glove compartment, and Sunny no exception. The exact location varies by generation:

• 🔧 Nissan Sunny B17 (2010–2017) — the filter is located behind the glove box (glove compartment), to the right of the center console. Access to it opens after removing the glove compartment.
• 🔧 Nissan Sunny N18 (2017–present) — similar, but the glove compartment fastening may differ (usually a plastic latch is used instead of a metal latch).

To get to the filter, you don’t need to disassemble half of the interior - just remove the glove compartment, which takes no more than 5 minutes. However, there is a nuance: in some trim levels Sunny (especially in basic versions for Asian markets) the cabin filter may missing from factory. In this case, you will need to purchase it separately and install it in the standard socket.

⚠️ Attention! If your Nissan Sunny released for the Japanese or Southeast Asian market, check the presence of a filter by VIN code or visually. In 20% of cases it is missing, and the hole is closed with a plug.

How do you know if the filter is clogged and needs to be replaced? Look out for these signs:

• 🌬️ Weak air flow from the deflectors even at maximum fan speed.
• 🤧 The appearance of an unpleasant odor (dampness, mold) when the air blower is turned on.
• 🚗 Quick fogging of windows in rainy weather.
• 🤒 Increased frequency of allergic reactions in passengers.

Which cabin filter to choose for Nissan Sunny?

There are three types of cabin filters on the market for Sunny:

1. Paper (regular) - the cheapest, they only trap large dust and insects. Service life: up to 15,000 km.
2. Coal — in addition to dust, they absorb harmful gases (benzene, nitrogen oxides) and unpleasant odors. Service life: up to 20,000 km.
3. Electrostatic — premium version with antibacterial coating. Even PM2.5 microparticles are retained. Service life: up to 25,000 km.

Nissan (original)	27277-4M00A	Coal	1 200–1 500	Guaranteed compatibility, high quality materials
Mann-Filter	CU 29 003	Coal	800–1 000	German quality, good filtration of small particles

Step-by-step instructions: how to change the cabin filter to Nissan Sunny?

Replacing the cabin filter with Sunny - one of the simplest procedures that even a beginner can handle. The whole process will take no more than 15 minutes. You will need:

• 🔧 New cabin filter (suitable in size and type).

• 🔨 Flathead screwdriver (in case the latches are tight).

Now let's start replacing:

1. Open the glove compartment and remove all things from it. Lower it all the way down - this will loosen the top latches.
2. Remove the restraints (plastic stops on the sides of the glove compartment). They are attached with latches - carefully pull them towards you.
3. Lower the glove compartment completelyby pressing the side latches. Some models Sunny You may need to unlatch the lower latch first (it's located under the glove compartment, closer to the floor).
4. You will see a plastic cover with the inscription Cabin Air Filter or without it. Carefully remove the cover by pulling it down (sometimes it is secured with latches).
5. Remove the old filter. It may be pressed by the seal - pull it towards you, slightly rocking it from side to side.
6. Clean the nest remove dust and debris with a damp cloth. Do not use a vacuum cleaner - it may damage the plastic guides!

If this is your first time changing a filter, we recommend filming the process or taking a photo of each stage. This will help avoid errors during reassembly.

What to do if the glove compartment cannot be removed?

If the glove compartment does not budge, check:

1. **Bottom latch** - sometimes it is hidden under the casing and requires pressing with a screwdriver.

2. **Side latches** - try pressing both stops (left and right) at the same time.

3. **Upper guides** - they may have caught on the dashboard. Gently pull the glove compartment down and towards you.

If all else fails, refer to the manual for your model or watch the video instructions for a specific year of manufacture Sunny.

Common mistakes when replacing the cabin filter

Even something as simple as replacing a filter can go wrong if you make one of these mistakes:

• 🔄 Installing the filter backwards. There is an arrow on the filter housing with the inscription Air Flow - she should watch down (towards the floor). If you put the filter the other way around, it will pass air less well and clog faster.
• 🧹 Ignoring nest cleaning. Dust and debris left in the box can immediately clog the new filter. Always wipe the nest with a damp cloth.
• 🔧 Power removal of the glove compartment. If the latches do not give way, do not pull the glove compartment with force - this will break the plastic latches. Better find a mounting diagram for your model.
• 🚫 Buying a filter without checking the size. Even if the article number is the same, some analogues may be 1–2 mm wider, which will complicate installation.
• 🔥 Using a vacuum cleaner to clean. A powerful air flow can damage the plastic guides or tear off the seals.

Another common problem is loose fit of the filter. If after installation you feel that air is passing past the filter (for example, through the cracks on the sides), check:

• Is the filter inserted correctly (it should fit in the grooves without play).
• Are the plastic guides in the socket bent?
• Are there any foreign objects (leaves, debris) that would interfere with a tight seal?

How often should you change the cabin filter?

Manufacturer Nissan recommends replacing the cabin filter every 15,000 km or once a year (whichever comes first). However, these terms are relevant for ideal operating conditions. In reality, the filter can clog much faster, especially if:

• 🏙️ You often drive around a city with high levels of smog or dust.
• 🌳 The car is parked under poplars or other trees that throw out fluff.
• 🚗 Use regularly Sunny on dirt roads.
• 🐕 Animals are often transported in the cabin (wool quickly clogs the filter).

To determine the optimal replacement interval, refer to visual filter status. It is enough to check it once every 3-4 months for heavy contamination. If the filter:

• Covered with a layer of dust more than 1–2 mm thick,
• Has visible signs of mold or moisture,
• Deformed or delaminated

— it needs to be replaced, even if the mileage has not reached 15,000 km.

An additional rule applies to carbon filters: they lose their absorbent properties through 6–8 months, even if they look clean on the outside. Therefore, it is recommended to change them more often than regular paper ones.

What happens if you don't change the cabin filter?

Many owners Nissan Sunny They neglect replacing the cabin filter, considering it a “minor” part. However, the consequences of such savings can be serious:

1. Deteriorating health. A clogged filter becomes a breeding ground for bacteria, mold and fungi. This is especially dangerous for allergy sufferers, asthmatics and children. According to statistics, the concentration of harmful microorganisms in a cabin with a dirty filter is 6 times higherthan on the side of a busy highway.
2. Damage to the ventilation system. Dust and debris enter the air ducts and clog the heater core and air conditioner evaporator. Repairing these units will cost tens of thousands of rubles.
3. Reduced air conditioner efficiency. A clogged filter impairs air circulation, causing the air conditioner to wear out and consume more fuel.
4. Unpleasant odors. Decaying organic matter (leaves, insects) in the filter becomes a source of persistent putrid odor, which cannot be removed with air fresheners.
5. Fogging of windows. Humid air does not pass through a clogged filter and condenses on the glass, impairing visibility and increasing the risk of an accident.

In extreme cases, failure to replace the filter can result in stove fan failure - its engine is not designed to operate with increased load caused by the resistance of a clogged filter.

⚠️ Attention! If in your Nissan Sunny a rotten smell appeared when the air conditioner was turned on, this is a sign of bacterial growth in the evaporator. In this case, it is not enough to change the filter - you will need to completely clean the air conditioning system with special means (for example, Step Up Anti-Bacteria).

FAQ: Frequently asked questions about replacing the cabin filter in Nissan Sunny

Is it possible to drive without a cabin filter?

Technically yes, but it is highly discouraged. Without a filter, all harmful particles from the road (dust, soot, pollen, bacteria), as well as unpleasant odors, will penetrate into the cabin. In addition, the absence of a filter will accelerate the wear of the heater fan and clog the heater radiator.

Which filter is better - carbon or regular?

A carbon filter is more effective at trapping harmful gases and odors, but is more expensive. A regular paper filter is suitable if you drive mostly on clean roads and do not suffer from allergies. For megacities and dusty regions, a carbon filter is the best choice.

How much does it cost to replace a cabin filter at a service center?

At official dealerships Nissan replacement will cost 800–1,500 rubles (excluding filter cost). In independent services the price is lower - 300–600 rubles. However, the procedure is so simple that it is irrational to do it in the service.

Can the cabin filter be washed and reused?

No, it's pointless. Paper and carbon filters cannot be washed properly - they lose their properties after getting wet. The exception is some reusable filters with an aluminum frame (for example, K&N), but they are not suitable for Nissan Sunny.

Why did the air in the cabin become weaker after replacing the filter?

Probable reasons:

• The filter is installed backwards (check the direction of the arrows).
• Debris has gotten into the air ducts (you need to blow out the system or contact service).
• The heater fan is faulty (diagnostics required).
