Where is the cabin filter located in the Nissan Cefiro A32?

Unlike many modern cars, where the filter is located behind the glove compartment or under the hood, in Cefiro A32 it's hidden in a less obvious place. The cabin air filter is located under the instrument panel, on the passenger side., next to the heater fan. To get to it, you will have to remove the lower part of the dashboard and the plastic cover.

The exact location depends on the year of manufacture and configuration:

• 🔧 Dorestyle (1992–1994): The filter is installed vertically, access to it is blocked by a plastic trim under the glove box.
• 🔧 Restyle (1994–1998): the filter has been moved slightly to the left, and the lid fastening has been changed (you will need to release 2 clips instead of 3).
• 🔧 Modifications with climate control: Additionally, it may be necessary to disconnect the temperature sensor connector.

If you have never changed the filter to Cefiro A32, be prepared for the fact that the factory filter may be glued to the fan housing - This is a typical problem for cars with high mileage. In this case, you will need to carefully pry it off with a flat screwdriver so as not to damage the plastic.

Signs that it's time to change the cabin filter

The manufacturer recommends replacing the cabin filter every 15–20 thousand km or once a year. However, in the conditions of Russian roads (dust, dirt, frequent driving on dirt roads), it is better to reduce the interval to 10–12 thousand km. The following symptoms indicate that the filter is clogged:

• 🌬️ Weak air flow from the deflectors even at maximum fan speed.
• 🤧 Constant smell of dust or mold in the cabin, especially when the heater is turned on.
• 🚗 Fogging of windows for no apparent reason (even in dry weather).
• 🔊 Extraneous noise (whistle, rattle) when the fan is running - this may mean that the filter has collapsed and its parts have gotten into the impeller.

If you ignore these signs, the consequences can be serious:

⚠️ Attention! A clogged cabin filter increases the load on the heater fan, which leads to premature wear. In extreme cases, the fan fuse or relay may blow (on Cefiro A32 this is F10 10A in the fuse box).

You can check the condition of the filter visually: if it is gray or black, with visible layers of dust and debris, replacement cannot be delayed. It is also worth paying attention to drainage hole under the filter (small rubber tube): if it is clogged, moisture will accumulate in the housing, which will lead to mold.

Which cabin filter to choose for Nissan Cefiro A32?

• 📏 Size: the standard filter has dimensions 200 × 190 × 20 mm (may vary slightly depending on manufacturer).
• 🔬 Filtration type: regular (retains only coarse dust) or coal (absorbs harmful gases and odors).
• 🏷️ Manufacturer: original filters Nissan (article 27277-4M000 or 27277-4M005 for coal) or high-quality analogues.

The table below shows proven analogues of the original filter:

Manufacturer	Article	Type	Average price, ₽	Features
Nissan (original)	27277-4M000	Regular	1 200–1 500	Guaranteed quality, but high price
Mann-Filter	CU 20004	Coal	800–1 000	Good filtration, long service life
Bosch	1 987 429 655	Regular	600–800	Budget option, suitable for urban use
Filtron	K 1152	Coal	700–900	Good price/quality ratio
SCT	SA 2019	Regular	400–500	The most budget-friendly, but the filtration quality is lower

4. Cleaning the Case
   

   Use a vacuum cleaner or damp cloth to remove accumulated dirt from the filter housing. If there are traces of mold, treat the surface with an antiseptic.

5. Installing a new filter
   

   Insert new filter down arrow (most filters have a directional arrow). Make sure it fits tightly into the grooves and does not wobble.

6. Reassemble in reverse order
   

   Close the cover, snapping all the clips into place, and replace the plastic trim. Connect the battery and check the fan operation at all speeds.

If after replacing the filter there is still an unpleasant odor in the cabin, it is recommended to disinfection of the ventilation system:

Typical replacement mistakes and how to avoid them

• 🔄 Installing the filter on the wrong side — if you place the filter with the arrow pointing up, it will not effectively trap dust, and it will quickly get into the cabin.
• 🔧 Damage to cover clamps — plastic clips are easy to break if you pull them with force. It's better to carefully pry them off with a screwdriver.
• 💧 Ignoring the drain hole — if you do not clean the rubber tube under the filter, water will accumulate in the housing, which will lead to mold.
• ⚡ Forgot to disconnect the battery — when working with plastic parts, you can accidentally short-circuit the wiring, which will damage the fan fuse.

Another common problem is debris getting into the fan when removing the old filter. If you hear extraneous noises after replacement, it means that parts of the filter or dirt have gotten onto the impeller. In this case, you will have to remove the heater fan for cleaning.

Frequently asked questions (FAQ)

Is it possible to drive without a cabin filter?

Technically yes, but this will quickly lead to dust clogging the heater core and fan. In addition, unfiltered air from the street will enter the cabin, which is harmful to health, especially if you drive in traffic jams.

How often do you need to change the cabin filter on Cefiro A32?

The optimal interval is every 10–15 thousand km or once a year. If you often drive on dusty roads or in a metropolis with a high level of pollution, it is better to replace it every 8-10 thousand km.

What is the difference between a carbon filter and a regular one?

In addition to mechanical dust removal, the carbon filter absorbs harmful gases (for example, nitrogen oxides from exhaust) and unpleasant odors. It is especially useful for residents of large cities. However, a carbon filter is more expensive and can clog faster.

Is it possible to wash the cabin filter instead of replacing it?

No, it's ineffective. The filter consists of a fibrous material, which, after washing, loses its properties and becomes a breeding ground for bacteria. It is better to buy a new one - its price is not commensurate with the health risks.

Where to buy a cabin filter for Nissan Cefiro A32?

The filter can be ordered in online stores (for example, Exist.ru, Autodoc, Kufar) or buy at retail auto parts stores (Auchan Auto, Detal-Opt). Original filters are usually available from official dealers Nissan, but their price is higher than their analogues.
