Cabin filter in Datsun on-DO with air conditioning located behind the glove compartment (glove box) on the front passenger side, which is a standard layout for platform vehicles Lada Kalina 2. To access it, you do not need to disassemble the entire dashboard or remove complex plastic covers; you just need to fold back or dismantle the glove compartment, after which access to the plastic cover of the air conditioner evaporator opens. It is in this place that the circulating air is cleaned of dust, pollen and soot before entering the ventilation system deflectors.
If you notice that in Datsun on-DO with or without air conditioning, the stove blows weakly or a foreign smell appears, then in 90% of cases the problem lies in a clogged filter element. Replacement required at least once a year or every 10-15 thousand kilometers, especially if the car is operated in dusty conditions. Ignoring this node results in air conditioner evaporator becomes overgrown with dirt, which causes mold, an unpleasant smell of dampness and reduces the efficiency of cooling the interior.
Before you start purchasing a new consumable, make sure that you have chosen the correct modification, since versions with and without air conditioning may have different mounting dimensions or design features of the case. Owners on-DO The location is often confused when trying to look for a filter under the hood or on the driver's side, but engineers placed this unit precisely in the access area from the passenger compartment to simplify maintenance. Below we will analyze in detail the process of searching, dismantling the old element and installing a new one, paying attention to important nuances.
Exact location and design features
In the car Datsun on-DO The filter element of the ventilation and heating system (cabin filter) is integrated into the air duct leading to the evaporator of the air conditioning system. It is located directly behind the rear wall of the glove compartment. You don't have to remove the glove compartment completely to see it; in many cases, it is enough to simply fold it down, after emptying it of its contents. However, for a comfortable and quick replacement, especially if you are doing this for the first time, it is recommended to complete dismantling plastic box.
The filter housing is a vertical plastic niche closed with a lid with latches. Inside there is the filter cardboard itself, which can be simple paper or carbon (with the addition of activated carbon). Coal options such as MANN-FILTER CUP 1829, better retain harmful gases and odors, which is important for city driving in traffic jams. The design is made in such a way as to minimize the suction of untreated air bypassing the filter, so the tightness of the lid plays a role here critical role.
⚠️ Attention: When looking for a filter, do not try to remove the decorative trim on the dashboard or disassemble the instrument panel. The cabin filter is located exclusively in the glove compartment area; any other actions may lead to breakage of the plastic clips of the dashboard.
It is important to note that in Datsun on-DO, as in related VAZ models, there are often two seat options: with and without a partition. In some configurations, the partition may be missing, and then the filter is installed in an open niche, requiring self-sealing of the edges. Check visually to see if you have a factory plastic guide frame. If it is not there, but the filter stands up freely, this may be a sign of previous unqualified intervention or a feature of a particular batch of cars.

Necessary tools and preparation
To carry out the replacement procedure, you do not need complex special tools or an inspection hole. The entire operation takes from 10 to 20 minutes, depending on skill. The main thing is to ensure good lighting of the work area, since the niche behind the glove compartment can be darkened. Use a flashlight or portable lamp to see the condition clearly latches and guides.
- 🔧 Phillips screwdriver (PH2) - for unscrewing the glove compartment mounting screws.
- 🔦 Flashlight or light source - to inspect the niche and check the cleanliness of the evaporator.
- 🧹 Vacuum cleaner or compressed air - to clean the niche from debris before installing a new element.
- 🧤 Gloves - to avoid getting your hands dirty from dust and dirt accumulated in the system.
Before starting work, it is recommended to warm up the interior or, conversely, cool it so that the plastic elements are not too cold and brittle, especially if the work is carried out in an unheated garage in winter. It is also worth preparing a new filter in advance: check its dimensions and the orientation of the airflow arrows. Incorrect installation (on the contrary) will sharply reduce filtration efficiency and create aerodynamic drag.
If you plan to not only replace, but also clean the system, prepare an antiseptic for air conditioners. This is a special foam that is blown through a tube into the drain or onto the evaporator after removing the filter. However, this must be done carefully, following the instructions for the chemistry, so as not to damage the electronic components Datsun on-DO.
Step-by-step instructions: removing the glove compartment
To get to the filter, you need to remove or lower the glove compartment. B Datsun on-DO The design of the glove compartment allows you to lower it down without completely disconnecting it, but for convenient filter replacement it is better to remove it completely. This will eliminate the risk of damage to the plastic hinges due to careless movement.
- Open the glove compartment and completely empty it of things, documents and small items.
- Locate the opening limiters on both sides of the glove compartment (inside). Lightly push the sides of the glove box inward to disengage the stoppers and lower the glove box lower than normal.
- Now pay attention to the fastening. In some versions on-DO The glove compartment is held on by two screws on the sides and one in the center (bottom or top). Remove all visible screws with a Phillips screwdriver.
- Gently pull the glove compartment towards you. It can be connected to the backlight (if included). If you see wires, do not pull sharply - disconnect the connector or simply move the glove compartment to the side, placing it on the floor or seat.
After removing the glove compartment you will see the end section of the heater/air conditioner. There will be a black or gray plastic cover that blocks access to the filter. It is usually rectangular in shape and secured with latches or one or two screws. B Datsun on-DO The most commonly used option is with latches around the perimeter of the lid.
☑️ Checklist before removing the cover
Replacing the filter element
By removing or snapping the cover, you will see the end of the old filter. Pay attention to the direction of airflow. There is always an arrow on the filter frame indicating the direction of air movement. B Datsun on-DO the air moves from top to bottom or from outside to inside, so the arrow should point down (or towards the cabin, depending on the specific geometry of the niche, but more often - down towards the evaporator).
Carefully remove the old filter. Be prepared for debris, leaves, or dust to fall out. Try not to shake it over an open evaporator so that dirt does not get inside the air conditioner heat exchanger. If the old filter appears flattened, warped, or gray/black in color, this is a direct indication for immediate replacement.
| Parameter | Description | Nuances for Datsun on-DO |
|---|---|---|
| Filter type | Salon (dust/carbon) | The presence of a coal layer is important for the city |
| Location | Behind the glove compartment (right) | Access from inside, no need to open the hood |
| Frequency | 10-15 thousand km or once a year | If you drive frequently on dirt roads, more often |
| Article (example) | 11180-8122010-00 | Analogs from Lada Kalina 2 are suitable |
| Evaporator status | Check visually | If heavily soiled, dry cleaning is required. |
| Tightness | Tight fit lid | Check latches for damage |
Install the new filter following the direction of the arrow. Make sure it fits snugly, without any distortions or wrinkles around the edges. If the filter “walks” in a niche, perhaps the wrong size was selected, or the sealing frame is missing. In the latter case, you can use thin foam rubber or sealing tape to close the gaps so that air does not bypass.
⚠️ Attention: Never leave a niche open without a filter, even for a short time while the fan is running. Large debris (leaves, insects) can instantly clog the air conditioner evaporator honeycomb, leading to costly repairs to the air conditioning system.
Nuances for versions with and without air conditioning
Although the filter location is Datsun on-DO the same for all versions, the presence of air conditioning (or climate control) makes adjustments to the service. In versions with air conditioning, behind the filter there is an evaporator - a radiator in which the air is cooled. If the filter has not been changed for a long time, a “felt felt” of fluff and dust forms on the evaporator, which, in combination with condensation, becomes an ideal environment for bacteria.
Owners of cars with air conditioning are strongly recommended to carry out preventive cleaning of the evaporator every second or third filter replacement. For this, there are special foam cleaners that are introduced through the drain tube or directly onto the evaporator cells after removing the filter. This helps eliminate the unpleasant “dirty socks” smell that often appears when the air conditioner is turned on after parking.
Expert Tip: When installing a new filter in a car with air conditioning, spray the edges with a small amount of antiseptic. This will create an additional barrier for microbes in the first days of operation.
In versions without air conditioning (stove only), the risk of mold formation is lower, since there is no constant condensation, but the requirement for air purity remains the same. A clogged filter in the “non-air conditioning” version will cause the windows to fog up much faster in winter, and the stove will work at half capacity, creating discomfort for the driver and passengers.
Typical installation errors
One of the most common mistakes is installing the filter upside down. If the airflow arrow is directed against the air movement, the flow resistance will increase many times over. As a result, you will hear the stove whistling, and the air pressure will be barely noticeable even at maximum fan speed. Always check the markings on the end of the frame before snapping the cover into place.
The second mistake is incomplete closing of the protective cover of the niche. Many owners, especially in a hurry, simply insert the filter and slam the glove compartment, forgetting to fix the filter cover itself or tighten the screws that secure it. This causes the filter to bend in an arc, and it ceases to perform its function, allowing dirt to pass around the perimeter.
The third mistake is using low-quality analogues. Cheap filters may not have a rigid frame or seal around the edges. B Datsun on-DO The filter niche is quite spacious, and soft cardboard without a rigid frame can collapse under the pressure of the air flow, blocking the ventilation completely. Choose trusted brands such as Mann, Bosch, Mahle or a high-quality original.
Main conclusion: Correct orientation of the filter arrow and tight fixation of the niche cover are the key to quiet and efficient operation of the ventilation system of your Datsun on-DO.
Frequently asked questions and answers (FAQ)
How often do you need to change the cabin filter in a Datsun on-DO?
The recommended replacement frequency is once a year or every 10-15 thousand kilometers. However, if you often drive on dusty roads, in a metropolis with traffic jams, or notice a deterioration in air flow, you should replace it more often, for example, every 5-7 thousand km.
Is it possible to drive without a cabin filter?
Highly not recommended. Driving without a filter leads to rapid contamination of the air conditioner evaporator and heater radiator. Cleaning them out is very difficult and expensive (requires disassembling the dashboard or removing the heater). Dust also gets into the lungs of passengers and settles on the upholstery.
Why does it still smell damp after replacing the filter?
A damp smell indicates the presence of mold on the air conditioner evaporator, which is located deeper than the filter. The filter itself only traps dust. To eliminate the smell, it is necessary to chemically clean the evaporator with a special antibacterial agent through the drainage hole or by removing the stove fan.
Is the filter from Lada Kalina 2 suitable?
Yes, Datsun on-DO built on a platform Lada Kalina 2, and most parts of the ventilation system, including the cabin filter (part number 11180-8122010-00), are completely interchangeable. You can safely use filters designed for Kalina 2.
What to do if the new filter does not fit?
Check that you are holding the filter correctly (the sides are not mixed up). If the dimensions are correct but the filter is tight, make sure there is no old debris or debris from the previous filter in the niche. Sometimes a slight adjustment of the edges helps, but you should not break the frame. Also check that the filter for the version with and without air conditioning is not mixed up (although they are usually identical, there are rare exceptions depending on the year of manufacture).
