Replacing the heater motor on a Nissan Note: instructions with photos and repair tips

Owners Nissan Note The first and second generations (E11/E12) sooner or later face the problem of a non-working stove. Most often the culprit is a worn-out heater fan motor, which either stops spinning or emits a high-pitched whistle. Replacing this unit at a service station costs 8–15 thousand rubles, but if you have the tools and patience, you can complete the procedure yourself in 2–3 hours.

In this article we will look at all stages of repair: from fault diagnosis to panel assembly. You will find out what motors are suitable for Nissan Note 2006–2020 model years (including restyled versions), how to avoid mistakes during disassembly and how original spare parts differ from analogues. We will also provide a compatibility table and give tips on extending the service life of the new fan.

Signs of a malfunctioning heater motor

The first symptoms of a problem with the heater fan appear long before complete failure. If you notice at least one of the following signs, you should check the condition of the motor:

• 🔊 Whistling or grinding noise when you turn on the stove (especially at speeds 3–4). Most often caused by worn bearings or debris getting on the blades.
• 🌀 Uneven operation: the fan either accelerates or slows down without changing the position of the regulator.
• 🚫 Failure of one or more speeds. For example, only speed 4 works, but speeds 1–3 do not (the resistor or motor brushes are to blame).
• 💨 Weak air flow even at maximum speed. The reason is jamming of the impeller or breakage of the winding.
• 🔥 Burning smell from deflectors. Indicates a short circuit or overheating of the stator winding.

On Nissan Note The heater motor is located under the dashboard on the passenger side. To accurately confirm its malfunction, it is enough to remove the lower dashboard trim and connect the fan directly to the battery (bypassing the resistor). If it does not spin or makes strange sounds, replacement is required.

⚠️ Attention: Don't confuse motor failure with problems. heater resistor or fuse F30 (10A). Before replacing, check the circuit with a multimeter: there should be + 12V at the motor connector when the ignition is on.

Choosing a motor: original vs analogues

For Nissan Note (E11/E12) suitable stove motors with catalog numbers:

Part type	Article	Manufacturer	Notes
Original	27350-4M000	Nissan	Suitable for all versions Note 2006–2020 Price: 6–9 thousand rubles.
Analogue (quality)	721000-0500	Denso	Direct replacement of the original. Price: 4–6 thousand rubles.
Analog (budget)	3540008F00	Valeo	Suitable for Note E11 (until 2013). Price: 2.5–3.5 thousand rubles.
Analogue	721000-0510	Mitsuba	Used in Micra K13 And Note E12. Price: 3–4.5 thousand rubles.

When choosing an analogue, pay attention to connector polarity And impeller size. Motors from Renault Clio or Dacia Sandero (For example, 7701059667) are similar in appearance, but have a different connection scheme and may not be suitable. Also check the package contents: some kits do not have an O-ring, which will have to be purchased separately (27355-4M000).

If your budget is limited, you can consider used motors from disassembly sites (price from 1.5 thousand rubles), but their service life rarely exceeds 1–2 years. New analogues from Denso or Mitsuba serve for 5–7 years with proper use.

Tools and preparation for replacement

To replace the heater motor with Nissan Note you will need:

• 🔧 Set of socket heads (8–10 mm) and extension.
• 🔨 Plastic spatulas for removing clips (or a flat screwdriver).
• ⚡ Multimeter for checking voltage.
• 🔌 Soldering iron (if you need to replace the resistor).
• 🧴 Silicone grease for the O-ring.
• 📦 New motor (see table above).

Before starting work:

1. Disable negative battery terminal (to avoid short circuit).
2. Place the steering wheel in the extreme right position - this will make access to the panel easier.
3. Prepare a place for storing removed parts (clips, screws, pads).

On models Note with climate control (E12 after 2013) you will additionally need to remove the heater control unit. For this you need a head 7 mm and accuracy - plastic latches are easy to break.

⚠️ Attention: On vehicles with a passenger airbag (SRS) before removing the panel, be sure to disconnect the yellow connector under the glove compartment. Otherwise an error may occur Airbag, which will have to be reset using a diagnostic scanner.

Step-by-step replacement instructions

The process of replacing the heater motor with Nissan Note includes 3 stages: disassembling the panel, dismantling the old fan and installing a new one. Let's look at each step in detail.

1. Removing the lower dashboard trim

Start by removing the plastic trim underneath the glove box:

1. Unscrew the 2 screws under the glove compartment (head on 10 mm).
2. Remove the clips around the perimeter of the cover (use a plastic spatula).
3. Disconnect the glove compartment light connector (white connector).

On models with air conditioning Additionally, remove the passenger's footwell air duct (held on by 3 clips). Under the cover you will see the black plastic housing of the heater motor.

2. Removing the old motor

Algorithm of actions:

1. Disconnect the power connector from the motor (press the latch).
2. Unscrew the 3 bolts securing the fan housing (head on 8 mm).
3. Carefully remove the motor along with the impeller. You may have to turn it counterclockwise.

Please note o-ring between the body and the motor. If it is torn or has lost elasticity, replace it (27355-4M000). Also clean the housing of any dust or debris that may have gotten onto the blades.

What to do if the motor cannot be removed?

If the fan is “stuck” to the case, do not pull it by force - this can break the plastic guides. Pour liquid over the joint WD-40 and wait 10–15 minutes. Then gently swing the motor left and right, while pulling it towards you.

3. Installing a new motor

Before installation:

• Check the rotation of the impeller manually - it should rotate without jamming.
• Apply a thin layer silicone grease onto the o-ring.
• Make sure that the connector of the new motor matches the old one (see photo below).

Installation is performed in reverse order:

1. Insert the motor into the housing until it clicks.
2. Tighten the 3 mounting bolts (tightening torque: 1.5 Nm).
3. Connect the power connector.
4. Check the operation of the stove at all speeds before assembling the panel.

If the fan does not work after replacement, check:

• 🔌 Fuse F30 (10A) in the block under the hood.
• 📶 Voltage on the motor connector (should be +12V on one of the contacts).
• 🔧 Condition of the stove resistor (located next to the motor).

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing the heater motor. Here are the most common ones and ways to prevent them:

• 🔧 Broken panel clips. When disassembling, do not pull the pads by force - first unclip all the latches with a spatula. Spare clips: 90467-04000.
• ⚡ Short circuit. Always disconnect the battery before working. If you forget, if the wire is shorted to the housing, the unit may burn out BCM.
• 🌀 Skewed impeller. When installing the motor, make sure that the impeller does not touch the walls of the housing. Otherwise there will be a whistle.
• 🔌 Incorrect connector connection. On 3-pin motors, the middle pin is ground. If you mix it up, the fan will work in the opposite direction.
• 💨 Forgotten O-ring. Without it, cold air will seep past the heater radiator, reducing heating efficiency.

Another common problem is noise after replacement. If the new motor whistles, check:

• Tightening the fastening bolts (loose bolts cause vibration).
• Condition of the bearings (on cheap analogues they often play).
• Cleanliness of air ducts (debris on the blades creates an imbalance).

If, after assembling the panel, the stove only works at 4th speed, the culprit is resistor (27352-4M000). It can be replaced separately or temporarily shorted pins 3 and 4 on the motor connector for testing.

How to extend the life of a new motor

The average life of the stove motor is Nissan Note — 5–7 years, but with proper use this period can be increased to 10 years. Follow these guidelines:

• 🌬️ Change the cabin filter regularly (every 15 thousand km). A clogged filter increases the load on the fan.
• 🚿 Clean your air ducts vacuum cleaner once a year. Dust and leaves get on the blades, causing imbalance.
• ❄️ Do not turn on the stove at full power in cold weather until the engine warms up. Cold air creates additional stress.
• 🔧 Lubricate bearings once every 2 years. Use lithium grease (not WD-40!).
• 💧 Avoid moisture. If the interior is damp, dry the floor mats and check the air conditioner drain.

If you often drive on dusty roads, install additional zero resistance filter (For example, K&N). It traps small particles better, but requires cleaning every 5 thousand km.

Also note quality of electricity in the on-board network. Voltage surges (for example, due to a faulty generator) reduce the life of the motor. The normal voltage on the battery when the engine is running is - 13.8–14.4V.

FAQ: Frequently asked questions about replacing the heater motor

Is it possible to repair an old motor instead of replacing it?

Yes, if the problem is brush assembly or bearings. To do this:

1. Disassemble the motor (unsolder the wires, remove the cover).
2. Clean the collector from carbon deposits (use an eraser or sandpaper 1000).
3. Replace the brushes (suitable for motors) Bosch 0130300019).
4. Lubricate the bearings.

However, such repairs are only justified for original motors. Cheap analogues do not last long after repair.

Why does the new motor only work at 4th speed?

This is a typical sign of a problem heater resistor (27352-4M000). It is responsible for adjusting speeds (except maximum). Replace the resistor or check its circuit with a multimeter:

• Resistance between pins 1–2: ~1 Ohm.
• Between 2–3: ~2 ohms.
• Between 3–4: ~3 ohms.

If there is no resistance, the resistor has burned out.

Which heater motor is suitable for other cars?

Complete analogues of the original motor 27350-4M000:

• Renault Clio 3 (7701059667) - fits the connector, but may differ in shaft length.
• Dacia Sandero (6001547696) - identical in characteristics.
• Suzuki Swift (35400-60G00) - requires modification of the connector.

Compare before purchasing impeller diameter (must be 140 mm) and connector polarity.

How long does it take to replace a motor?

Time depends on experience and vehicle equipment:

• Without air conditioning: 1.5–2 hours.
• With air conditioning: 2.5–3.5 hours (requires removal of air ducts).
• With climate control: 3–4 hours (you need to turn off the control unit).

Pre-marking the screws and clips with a marker will help speed up the process.

What should I do if after replacement the stove blows cold air?

Causes and solutions:

• Heater tap jammed — check the control cable (27360-4M000).
• Air lock in the cooling system — warm up the engine with the expansion tank cap open.
• Thermostat is faulty - replace (21200-4M005 for Note E11).
• Clogged heater radiator - wash or replace (27300-4M000).
