Nissan Note is a popular compact van, but its owners often encounter problems with noise or complete failure of the heater fan. If the cabin has become cold, and extraneous sounds are heard from under the dashboard, most likely the heater motor is to blame. In this article, we will look at how to diagnose a malfunction, select a high-quality fan and replace it with your own hands - without going to a service station.

Replacement procedure for Nissan Note (body E11 And E12) has nuances: on some modifications you will have to remove the glove compartment or part of the dashboard. We will describe both options in detail, indicate the original article numbers of spare parts and analogues, and also give advice on how to extend the life of the new fan. If you have never repaired a car, don’t worry: with the right approach, the work will take no more than 2-3 hours.

Signs of a malfunctioning stove fan

The first signal about problems with the fan is sound change when the heater is operating. In the early stages it may be a subtle squeaking or crackling noise, but over time the symptoms get worse. Here are the key signs that the heater motor Nissan Note requires replacement:

  • 🔊 Extraneous noise (grinding, squealing, knocking) when the airflow is turned on in any mode. The most common cause is worn bearings or debris getting into the impeller.
  • 🌬️ Weak or uneven air flow even at maximum speed. This may indicate problems with the motor or clogged air ducts.
  • 🚫 Complete lack of reaction to switch fan modes (the fan does not turn on in any of the control positions).
  • 🔥 Burning smell from the deflectors - a sign of a short circuit or overheating of the motor windings.

On Nissan Note first generation (E11, 2004–2012) the stove fan more often fails due to structural defect of bearings, which are not designed for long-term operation in dusty conditions. In the second generation (E12, 2012–2020) the problem is less common, but is also relevant for cars with mileage over 150 thousand km.

Before buying a new fan, make sure the problem is not with the fuse (F30, 10A) or relay (R17). Also check the functionality of the speed resistor (located next to the motor) - its malfunction can simulate a fan breakdown.

Which heater fan to choose for Nissan Note: original vs analogues

Original heater fan for Nissan Note E11 has an article number 27310-4M000 (or 27310-4M00A for restyled versions). For E12 fits 27310-4M500. The cost of the original part is from 8 to 12 thousand rubles, which seems unreasonably expensive to many. Fortunately, there are high-quality analogues:

Manufacturer Article Price, rub. Features
Nissan (original) 27310-4M000 (E11)
27310-4M500 (E12)		 8 000–12 000 1 year warranty, fully compatible
Denso 727-1001 5 500–7 000 Japanese quality, quiet operation
Valeo 713001 4 800–6 200 Good resource, but can be noisy at high speeds
Febi 27310 3 500–4 500 Budget option, average resource
Hella 8FL 358 369-041 6 000–7 500 German quality, suitable for E11 and E12

When choosing an analogue, pay attention to connection polarity — some non-original fans have wires reversed, which can lead to incorrect operation. Also check the package: the box should contain the motor itself, the impeller and the o-ring.

⚠️ Attention: Do not buy cheap Chinese analogues without a brand (price up to 2,000 rubles). They often have a weak motor that burns out after 3-6 months, and a plastic impeller whose blades break due to vibration.

If you want to save money, look for used original fans at disassembly sites. The main thing is to check their performance before purchasing. The average price of a used part is 2,000–3,500 rubles.

Preparing for replacement: tools and safety precautions

To replace the stove fan with Nissan Note you will need:

  • 🔧 Tools: Phillips and flat-head screwdrivers, 10 mm socket with extension, 8 mm socket wrench, pliers, knife for cutting the seal.
  • 🔌 Additionally: flashlight (for illuminating hard-to-reach places), multimeter (for checking power), silicone grease (for seals).
  • 🚗 Consumables: a new fan, an O-ring (if not included), electrical tape or heat shrink for the wires.

Before starting work disconnect the negative terminal of the battery - this will prevent a short circuit if the wires are accidentally connected. We also recommend removing fuse F30 (10A) from the block in the cabin - it is responsible for the fan circuit.

If you're working in a garage, make sure there's plenty of light. On Nissan Note E12 To access the fan you will have to remove the glove compartment, so empty it of things in advance. On E11 It may be necessary to partially dismantle the torpedo - we will talk about this below.

⚠️ Attention: Do not start disassembling if you are not confident in your abilities. On Note E11 If you remove the panel carelessly, the fastening clips or airbag connectors can be damaged. If in doubt, take photographs of each stage of disassembly so that you can reassemble everything correctly later.

Step-by-step instructions: replacing the heater fan on a Nissan Note E11

On the first generation Nissan Note (E11) access to the fan is difficult - you will have to remove part of the torpedo. Follow the instructions:

  1. Remove the decorative trim under the steering wheel. It is attached with 3 clips. Carefully pry it off with a flat head screwdriver, starting from the bottom edge.

  2. Unscrew the bolts securing the lower part of the dashboard (2 10mm bolts under the glove box and 1 8mm bolt to the left of the steering column).

  3. Lower the steering column to the lowest position and remove the plastic cover underneath (held on by 2 clips).

  4. Disconnect the connectors from the heater control unit (they are located to the right of the fan). Remember or take a photo of the connection order.

  5. Get to the fan: it is located behind a plastic casing, which is secured with 3 8 mm bolts. Remove the casing and disconnect the power connector from the motor.

  6. Remove the 3 fan mounting bolts (with an 8 mm socket wrench) and carefully remove it along with the impeller. Be careful - the blades are plastic and may break!

  7. Install a new fan in reverse order. Don't forget to check the O-ring - if it is torn, replace it.

On Note E11 with air conditioning, additional removal of the evaporator may be required - this complicates the process. If you have such a configuration, it is better to contact additional instructions.

Features of replacement for Note E11 with air conditioning

On cars with climate control or air conditioning, the heater fan is located behind the evaporator. To remove it, you will have to:

1. Bleed freon from the system (required! otherwise, when dismantling the tubes, a leak will occur).

2. Disconnect the air conditioner pipes from the evaporator (special wrenches are required).

3. Remove the evaporator together with the housing to get to the fan.

It is better to entrust this work to specialists, since after assembly the air conditioning system must be refilled and checked for leaks.

After installing the new fan, check its operation at all speeds. If you hear a whistle at maximum mode, most likely the impeller is touching the housing. In this case, bend the blades slightly or check that the O-ring is installed correctly.

Replacing the heater fan on a Nissan Note E12: simplified diagram

On the second generation (E12, 2012–2020) the design has been simplified - you can get to the fan through the glove compartment. Here are the step-by-step instructions:

  1. Remove the glove compartment. To do this, unscrew the 4 fastening bolts (2 from below and 2 inside the glove compartment) and disconnect the opening limiters.

  2. Unscrew the plastic panel under the glove compartment (held by 3 clips and 1 10 mm bolt).

  3. Find a fan — it is located to the right of the central air duct, in a plastic casing.

  4. Disconnect the power connector and unscrew the 3 mounting bolts (with an 8 mm socket wrench).

  5. Remove the old fan and install a new one. On E12 There is often a problem with the length of the wires - if they are short, do not pull them, but carefully pull out the motor along with the casing.

On Note E12 with the system NissanConnect (multimedia screen) When removing the glove compartment, you may need to disconnect the antenna cable. Don’t pull on it—it’s better to unscrew the connector from the back.

After replacement, check the operation of the fan in all modes. If it does not turn on at speeds 1–2, the problem may be speed resistor (article 27315-4M000). Replacing it takes 10 minutes and costs about 1,500 rubles.

💡

Before installing a new fan, apply a few drops of silicone grease to the motor axle. This will reduce noise and extend bearing life.

Common replacement mistakes and how to avoid them

Even experienced car owners sometimes make mistakes that lead to repeated breakdowns or additional expenses. Here are the most common:

  • ⚡ Incorrect connector connection. On some analogues, the wires are reversed - if the fan spins in the opposite direction, reverse the polarity. Long-term operation in this mode will lead to overheating of the motor.
  • 🔧 Tightening the fastening bolts. This deforms the fan housing and leads to vibration. Tighten the bolts with a force of no more than 5 Nm.
  • 🌡️ Ignoring resistor testing. If after replacement the fan only works at speed 3-4, the resistor (located next to the motor) is to blame.
  • 🚫 They forget about the o-ring. Without it, cold air will penetrate into the cabin, and the fan itself will make noise due to play.

Another common mistake is buying a fan without an impeller. Some sellers only offer the motor, but the original impeller Nissan balanced at the factory. Installing a non-original impeller will lead to vibration and premature wear of the bearings.

⚠️ Attention: If after replacement the fan operates jerkily or with pauses, check the voltage at its connector with a multimeter. The device should show 12V at maximum speed. If the voltage is below 10V, there is a problem in the wiring or the heater control unit.

On Nissan Note with the system climate control After replacing the fan, you may need to reset errors. To do this, disconnect the battery for 10 minutes or reset the settings via the diagnostic connector.

How to extend the life of a new furnace fan

To help your new fan last longer, follow these tips:

  • 🌿 Change the cabin filter regularly. A clogged filter increases the load on the motor, which leads to overheating. On Note the filter is located behind the glove compartment - change it every 15 thousand km.
  • 🚿 Clean your air ducts. Once a year, blow out the system with compressed air (you can use a compressor or a can). This will remove dust and debris that gets caught on the impeller.
  • 🔄 Do not turn the stove on high right away. In cold weather, let the motor warm up for 1–2 minutes at speed 1–2 to avoid sudden load.
  • 🔧 Lubricate bearings. Once every 2 years, apply 1-2 drops of silicone grease to the fan axis (do not use lithol or grease - they collect dust!).

If you often drive on dusty roads, install additional zero resistance filter at the air duct inlet. It will trap large particles but will not impede air flow.

On Nissan Note E12 with the system NissanConnect Stay tuned for climate control firmware updates. There was a bug in some versions of the software that caused the fan to run at higher speeds even when the stove was turned off. The update solves this problem.

💡

The main reason for the early failure of the heater fan on a Nissan Note is dust and debris falling on the impeller. Regular cleaning of air ducts and timely replacement of the cabin filter will extend the life of the engine by 2-3 times.

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, the bearing or motor winding fails. The bearing can be replaced (part number 6201ZZ), but this requires disassembly and pressing. It is almost impossible to rewind the winding - it is easier to buy a new fan.

If the problem is in the impeller (broken blades), it can be replaced separately (part number 27312-4M000), but it will cost 3,000–4,000 rubles. - almost like a new motor assembly.

How long does it take to replace a fan?

On Nissan Note E12 (through the glove compartment) - 1–1.5 hours. On E11 (with removal of the torpedo) - 2.5–3 hours if done for the first time. Experienced professionals can complete the job in 40–60 minutes.

Why is the new fan noisier than the old one?

Possible reasons:

  1. The impeller is touching the housing (check the O-ring).
  2. Wrong polarity of connection (swap wires).
  3. Bearing defective (return the fan under warranty).
  4. Debris remains in the air ducts (blow out the system with compressed air).
Is it possible to drive without a heater fan?

Technically yes, but it is inconvenient and dangerous:

  • In winter, the interior will not warm up, which will lead to fogging of the windows.
  • In summer, the air conditioner (if there is one) will not work.
  • When driving for a long time without airflow, the heater radiator may overheat.

If the fan breaks down on the road, you can get home, but it’s better not to delay repairs.

Where can I buy a heater fan for Nissan Note cheaper?

The most profitable options:

  • Car disassembly: used original for 2,000–3,500 rubles. (check if it works!).
  • AliExpress: new analogues from 3,000 rubles, but delivery takes 2–4 weeks.
  • Local online stores: look for promotions on Denso or Hella (can be found with up to 30% discount).
  • Avito: They often sell new spare parts from disassembly sites at a price below the market price.

Do not buy in the markets - there is a high risk of running into a fake.
