Heater fan (heater motor) on Nissan Note - one of those units that sooner or later fails. Model owners especially often have problems. E11 (2006–2012) And E12 (2012–2020), where the design of the heating system has its weak points. If you notice that the stove is blowing weaker, extraneous noise has appeared, or has stopped working altogether, most likely the fan is to blame.
In this article we will look at all stages of replacement: from diagnosing a malfunction to installing a new motor. You will learn what tools are needed, how to remove the panel correctly so as not to break the clips, and what hidden nuances often missed even by experienced craftsmen. We’ll also tell you how to save on spare parts without sacrificing quality.
Signs of a malfunctioning heater fan on a Nissan Note
The first signal that something is wrong with the fan is change in stove operation. But the problem is not always obvious. Here are typical symptoms to look out for:
- 🔊 Extraneous sounds (grinding, squealing, knocking) when the heater is turned on. Most often this indicates wear of the bearings or debris getting on the blades.
- 💨 Weak air flow even at maximum speed. The reason is a jammed motor or a broken winding.
- 🚫 The stove doesn't turn on at all. This could be either a malfunction of the fan itself or a problem with the fuse (
F3010A) or relay (R17). - 🔥 Burning smell from the air ducts - a sign of a short circuit or overheating of the winding.
If you notice at least one of these signs, do not delay diagnosis. Nissan Note It is known that if the problem is ignored, the fan can completely fail, and debris from it can end up in the cabin filter or even in the heater radiator.
⚠️ Attention! If the heater stops working after washing the car or heavy rain, first check fuse F30 and the motor connector for moisture. Often the problem is solved by simply drying the contacts.
What tools and spare parts will be needed
Before you start replacing, prepare everything you need. Depending on the year of manufacture Nissan Note (E11 or E12) different parts may be required, but the tools needed are the same:
| Category | Name | Note |
|---|---|---|
| Tools | Phillips screwdriver (PH2) | To remove the panel and mount the fan |
| Tools | Flathead screwdriver or plastic puller | For removing clips without damage |
| Tools | 10 mm socket with extension | To unscrew the motor mounting bolt |
| Spare parts | Heater fan (heater motor) | Original: 27270-4M000 (E11), 27270-4M010 (E12) |
| Spare parts | Cabin filter | It is recommended to replace it together with the fan |
When choosing spare parts, pay attention to the manufacturer. Original fans from Nissan They last longer, but are more expensive (from 4,500 to 6,000 rubles). Good analogues:
- 🔧 Febi (article
27270) - a reliable budget option (about 3,000 rubles). - 🔧 Valeo (article
717268) - high quality, price ~4,000 rub. - 🔧 Denso - premium segment, but not suitable for all model years.

If you buy a used fan, be sure to check its functionality before installation. Connect to the battery (positive on the red wire, negative on the black) and make sure that it rotates without noise.
Preparing for replacement: removing the panel and accessing the fan
The most time-consuming step is dismantling the panelto get to the stove motor. On Nissan Note You don't need to remove the entire dashboard to do this, but you will need to be careful not to break the clips.
Sequence of actions:
- Disable negative battery terminal (required!).
- Remove glove compartment: Unscrew 6 bolts (4 on the bottom, 2 on the inside) and disconnect the backlight connector.
- Dismantle bottom panel trim (under the steering wheel) - it is attached to 3 clips.
- Unscrew gas pedal mounting bolt (10 mm head) and move it to the side.
- Remove decorative overlay around the radio (carefully pry it off with a screwdriver).
- Unscrew the 2 mounting bolts stove control unit and disconnect the connectors.
You should now have access to the fan housing. It is located to the right of the gas pedal and is secured with one bolt and three clips.

⚠️ Attention! On models Nissan Note E12 (2012–2020) the heater control unit can be integrated with climate control. If you have this version, take a photo of the location of the connectors before disconnecting so as not to get confused during reassembly!
Step-by-step instructions for replacing the stove fan
Once access to the motor is open, you can begin to replace it. Follow the instructions to avoid errors:
- Disconnect the power connector from the fan (it is located on the side and is secured with a latch).
- Unscrew the fastening bolt (10 mm head) - it is located in the lower part of the body.
- Carefully rotate the fan housing counterclockwise and pull it out of its seat. Be careful - there may be pieces of plastic or debris inside!
- Compare old and new fans. Make sure the blades are identical in shape and size and that the connector fits.
- Install a new motor in reverse order. In this case:
- 🔩 Tighten the fastening bolt firmly no more than 5 Nm (tightening can break the body).
- 🔌 Check that the connector is seated until it clicks - poor contact will lead to overheating.
After installation don't rush to assemble the panel. First, connect the battery and check the operation of the stove at all speeds. If the new fan makes strange noises, it may be defective or incorrectly installed.
Before final assembly, turn on the stove at maximum speed and listen. If you hear a whistle, check whether the blades are touching the body. Sometimes bending the fasteners slightly helps.
Typical replacement mistakes and how to avoid them
Even experienced car owners make mistakes, which then result in repeated repairs. Here are the most common:
- 🔧 Damage to the clip panel. If you break even one, the panel will rattle. Use a plastic puller!
- 🔌 Incorrect connector connection. On Nissan Note E12 The motor connector has a key - if it does not latch, the contacts may melt.
- 🌀 Installing the fan upside down. The blades must rotate clockwise (when viewed from the motor side).
- 🔩 Fastening bolt tightening. This leads to cracks in the housing and vibration.
Another common problem is forget to check the cabin filter. If it is clogged, the new fan will work harder and fail faster. On Nissan Note The filter is located behind the glove compartment and replacing it takes no more than 5 minutes.
What should I do if, after replacement, the stove only works at 4th speed?
This is a sign of a problem heater resistor (article 27275-4M000). It is located next to the motor and often burns out if there is a short circuit. Replace it along with the fan to avoid repeated repairs.
How much does it cost to replace a stove fan at a service center?
If you are not confident in your abilities, you can contact a car service. The cost of work depends on the region and complexity:
| Service type | Cost of work (rub.) | Cost of spare part (RUB) | Total (RUB) |
|---|---|---|---|
| Official dealer | 6 000–8 000 | 5,000–6,500 (original) | 11 000–14 500 |
| Unofficial service | 3 500–5 000 | 3,000–4,500 (analog) | 6 500–9 500 |
| Self-replacement | 0 | 3 000–6 500 | 3 000–6 500 |
As you can see, Do-it-yourself repairs can save up to 50%. The main thing is to take your time and follow the instructions. If you have never disassembled the panel, practice removing the glove compartment and lower trims to understand how the clips are secured.
Replacing the stove fan with Nissan Note - this is 3-4 hours of work for a beginner and 1.5-2 hours for an experienced master. Most of the time is spent on carefully dismantling the panel, and not on replacing the motor itself.
Prevention: how to extend the life of a new ventilator
To make your new stove motor last longer, follow these tips:
- 🌿 Change the cabin filter every 15,000 km. A clogged filter increases the load on the fan.
- 🚿 Avoid moisture into the air ducts. After washing, check if water is leaking under the hood.
- 🔊 At the first sign of noise (creaking, squealing) check the bearings. Sometimes it is enough to lubricate them with silicone grease.
- 🔌 Don't turn the stove on high immediately after starting the engine in winter. Let the engine warm up for 1-2 minutes.
If you live in an area with high humidity, treat the fan connector contacts lithium grease (For example, LIQUI MOLY Electronic-Spray). This will prevent oxidation and short circuit.
FAQ: Frequently asked questions about replacing the heater fan on a Nissan Note
Is it possible to repair an old fan instead of replacing it?
Theoretically yes, but this is a temporary solution. Most often, a bearing or motor winding fails. If you have experience in electrical engineering, you can:
- Disassemble the housing and lubricate the bearings.
- Check the winding with a multimeter (resistance should be 2–5 Ohms).
- Replace brushes (if they are worn out).
However, in 80% of cases, such repairs do not help for long, and after 3-6 months the fan breaks down again. Therefore replacement is a more reliable option.
Which fan is better to choose: original or analogue?
Original fans (27270-4M000/27270-4M010) last longer (lifespan ~150,000 km), but are more expensive. Analogues (Febi, Valeo) is cheaper, but:
- May become noisier at high speeds.
- Service life - 80,000–100,000 km.
- Some models do not have moisture protection.
If your budget allows, take the original. If you want to save money, choose Valeo (best price/quality ratio).
Do I need to completely remove the dashboard to replace the fan?
No, on Nissan Note It is enough to remove the glove compartment, the lower panel trim and the heater control unit. Complete dismantling of the dashboard is required only when replacing the heater radiator or air conditioner evaporator.
Why does the stove only blow cold air after replacing the fan?
This is not related to the fan. Probable reasons:
- Jammed stove damper (check the damper cable or motor).
- Low antifreeze level or air lock in the cooling system.
- Defective thermostat (the engine does not warm up to operating temperature).
Start by checking the antifreeze level and the operation of the damper.
Is it possible to drive without a heater fan?
Technically yes, but this creates several problems:
- In winter, the interior will not warm up well (heat will flow only through natural circulation).
- In summer, the air conditioning will not work (the fan drives air through the radiator).
- The risk of glass fogging increases.
If the heater does not work, try not to drive in rain or snow - this is dangerous due to poor visibility.
