Owners Nissan Juke (especially models F15 2010–2019) often encounter a problem when the stove stops blowing warm or cold air. The reason for this is a non-working heater fan. The situation is unpleasant: in winter the interior does not warm up, in summer the air conditioner does not cool, and condensation constantly forms on the windshield. But there is no need to panic: in 80% of cases the problem can be fixed on your own, without resorting to expensive service.

In this article we will look at all possible reasons, according to which the stove fan Juke can fail - from a banal blown fuse to wear on the electric motor brushes. You will learn how to check each element of the system, where to look for a fault and what to do to fix it. And if you are not confident in your abilities, we will tell you how much repairs will cost in the service and how to save on spare parts.

1. Heater fan fuse: where is it located and how to check

The first thing to do if a fan fails is check the fuse. B Nissan Juke The fuse is responsible for the operation of the stove F37 (10A), located in the mounting block under the steering wheel. Access to it opens after removing the cover (it is secured with two latches).

To make sure the fuse is good:

  • 🔍 Visually inspect it for the presence of a broken thread or melting of the body.
  • 🔧 Ring with a multimeter in circuit test mode (resistance should be close to 0 ohms).
  • 🔄 Replace with a known good one (for example, temporarily install a fuse with the same amperage from another slot, e.g. F38 for the cigarette lighter).

If after replacing the fuse the fan starts working, but after a while it stops blowing again - look for short circuit in the chain. Most often it occurs due to damage to the insulation of the wires under the panel or in the resistor block.

⚠️ Attention: Never install a fuse with a higher rating (for example, 15A instead of 10A)! This may cause the wiring to catch fire.

  • Yes, I changed it myself
  • Yes, but in the service
  • No, I never had to
  • I don't know where they are

2. Fan relay: how to find and test it

If the fuse is good, the next one in line is - fan relay (K3 in the mounting block). It is responsible for supplying power to the stove motor. B Juke The relay is located next to the fuses, but testing it requires a little more effort.

Diagnostic algorithm:

  1. Remove the relay K3 (it is usually black with markings 30A).
  2. Call contacts 85 And 86 (coil): resistance should be ~70–120 Ohms.
  3. Apply 12V to the contacts 85 And 86 - a click should be heard (contacts closing 30 And 87).

If the relay does not click or the contacts do not close, it needs to be replaced. Cost of a new relay for Juke - from 300 to 800 rubles. But before buying, make sure that this is the problem: sometimes the contacts oxidize, and it is enough to clean them with alcohol.

Where to buy an original relay for Nissan Juke?

Original relay Nissan 25230-JM00A can be ordered from official dealers or trusted online stores (Exist.ru, Autodoc). Analogues: Hella 4RA 003 594-331 or Bosch 0 332 019 150.

3. Heater resistor: why does it burn and how to replace it

One of the most common reasons for fan failure is Nissan Juke — faulty resistor (aka additional resistor or resistance block). It regulates the rotation speed of the stove motor, and if it breaks down, the fan either works only at maximum speed or does not turn on at all.

Signs of a faulty resistor:

  • 🔥 The fan only blows at speed 4 (maximum).
  • 🔊 When switching speeds, clicks are heard, but no air flows.
  • 💨 The stove operates in jerks or turns off spontaneously.

To get to the resistor:

  1. Remove the glove compartment (it is secured with 4 screws and 2 latches).
  2. Behind the glove compartment you will see a black plastic block with a connector - this is a resistor.
  3. Disconnect the connector and check the resistance between the contacts (should be ~0.5–5 Ohms depending on the speed).

If the resistor is burnt out, it needs to be replaced. Original part (Nissan 27440-JM00A) costs ~1,500–2,500 rubles. Analogues from Febi or Valeo will cost less (800–1,200 rubles).

Manufacturer Article Price, rub. Compatibility
Nissan (original) 27440-JM00A 1 800–2 500 Juke F15 (2010–2019)
Febi 27440 900–1 200 Complete analogue
Valeo 718508 1 100–1 500 Suitable for Juke and Renault Captur
⚠️ Attention: When replacing a resistor, be sure to check the condition of the connector! Often the contacts burn or melt, which leads to repeated failure of the part. Clean them with fine sandpaper or replace the entire connector.

4. Fan electric motor: diagnostics and repair

If the fuse, relay and resistor are good, but the fan still does not work, the problem is electric motor. B Nissan Juke it is located behind the glove compartment, next to the resistor. To check it:

  1. Disconnect the power connector from the motor.
  2. Apply 12V directly from the battery to the motor contacts (plus on +, minus by –).
  3. If the motor does not spin, it is burnt out or jammed.

Frequent causes of motor failure:

  • 🔋 Brush wear (a characteristic sign is that the fan runs jerkily).
  • 🌀 Bearing jamming (the motor hums, but does not rotate).
  • 💥 Winding break (complete lack of response to nutrition).

Motor repair is possible if the problem is in the brushes or bearings. To do this you need:

  1. Disassemble the motor housing (it is usually glued or snapped together).
  2. Clean the collector from carbon deposits (use alcohol and a soft cloth).
  3. Replace the brushes (suitable ones can be found in radio parts stores).
  4. Lubricate bearings Litolom-24 or similar lubricant.

If the motor is completely burnt out, it is easier to replace it. Original part (Nissan 27400-JM00A) costs ~4,000–6,000 rubles. Analogues from Denso or Mitsuba will cost 2,500–4,000 rubles.

5. Problems with wiring and connectors

Sometimes the fan does not work due to wiring break or poor contact in the connectors. B Nissan Juke special attention should be paid to:

  • 🔌 Fan motor connector (often oxidizes or comes off).
  • 🔗 Wires from resistor to motor (they may rub against the body).
  • 📡 Body weight (poor mass leads to unstable operation of the stove).

How to check wiring:

  1. Disconnect the connectors on the motor, resistor and heater control unit.
  2. Test the circuit with a multimeter to check for an open (resistance should be close to 0 ohms).
  3. Check the voltage at the motor connector with the heater on (should be 12V).

If you find a break, restore the circuit by soldering or replacing the wire. To protect against repeated chafing, use corrugated tape or electrical tape. It will also not be superfluous check the mass on the body under the dashboard - it often oxidizes, which leads to “floating” heater malfunctions.

6. Stove control unit and its malfunctions

Less common in Nissan Juke fails heater control unit (aka stove controller). It is located on the center console and is responsible for adjusting the fan speed, temperature and air direction. Signs of its malfunction:

  • 🎛️ The stove buttons do not respond or work chaotically.
  • 🔄 The fan spontaneously changes speed.
  • 💡 Incorrect characters are displayed on the display.

You can check the block like this:

  1. Remove the stove control panel (it is secured with latches).
  2. Disconnect the connector and check the voltage at the contacts (there should be 12V on the power supply and ~5V on the signal wires).
  3. If there is voltage, but the unit does not work, it is faulty.

Repairing the control unit is complicated and often impractical - it’s easier to replace it with a new one (Nissan 27770-JM00A, ~5,000–8,000 rubles) or used (~2,000–3,000 rubles). Before purchasing, make sure that the unit is suitable for your modification Juke (with or without climate control).

💡

If the stove operates only at maximum speed, and other modes do not turn on, in 90% of cases the resistor is to blame, not the control unit. Don't rush to change your expensive controller!

7. When to contact the service and how much it will cost

If you have checked all the elements, but the heater fan is in Nissan Juke still doesn't work, maybe the problem is deeper:

  • 🔧 The dampers are jammed (disassembly of the torpedo is required).
  • 🔥 Short circuit in wiring harness (diagnostics with a multimeter is needed).
  • 🛠️ ECU malfunction (extremely rare).

In this case, it is better to contact the service. Average prices for repairs in Moscow and the regions:

Type of work Cost, rub. Lead time
Diagnostics of stove electrics 1 000–1 500 30–60 minutes
Replacing the fan resistor 1,500–2,500 (with part) 1–1.5 hours
Replacing the Fan Motor 3,500–5,000 (with part) 2–3 hours
Wiring/connector repair 2 000–4 000 1.5–2 hours

To save money, you can buy spare parts yourself (for example, Exist.ru or Autodoc) and bring them to the service. Also, many workshops offer discounts for complex repairs (for example, replacing a resistor + cleaning connectors).

💡

Before going to the service center, be sure to reset the ECU errors (disconnect the battery terminal for 10 minutes) - sometimes the stove does not work due to a temporary failure in the electronics.

Frequently asked questions (FAQ)

Why does the heater fan only work at speed 4?

This is a sign of a malfunction resistor. At maximum speed, the current bypasses the resistor, so the fan spins. At speeds 1–3, current passes through the resistor, and if it burns out, the stove does not blow. Solution: replacing the resistor (Nissan 27440-JM00A).

Is it possible to drive if the heater fan does not work?

Technically it is possible, but it is not safe:

  • In winter, the interior will not warm up, which will lead to fogging of windows and reduced visibility.
  • In summer, the air conditioner will not be able to cool the air, which will create discomfort.
  • When driving for a long time with the heater not working, it may heater core overheat (in rare cases).

We recommend that you fix the problem as soon as possible.

How to remove the heater fan motor on a Nissan Juke?

Procedure:

  1. Remove the glove compartment (4 screws + 2 latches).
  2. Disconnect the power connector from the motor.
  3. Unscrew the 3 motor mounting bolts (you need Torx T20).
  4. Carefully remove the motor along with the impeller.

Assembly is carried out in reverse order. Be careful not to damage the fan blades!

How much does a new blower motor cost for a Juke?

Prices for stove motor (Nissan 27400-JM00A):

  • Original: 4,000–6,000 rubles.
  • Analogues (Denso, Mitsuba): 2,500–4,000 rubles.
  • Used: 1,500–2,500 rubles (risk of purchasing a faulty part).

When purchasing, check whether the motor is suitable for your year of manufacture Juke (dorestyle or restyle).

Could the fan not work due to the battery?

Yes, but indirectly. If the battery is weak or the terminals are oxidized, the voltage in the on-board network may drop below 12V. In this case:

  • The heater ECU may drive incorrectly fan.
  • The relay and fuse may don't work due to low voltage.
  • The fan motor can rotate too slowly or not start.

Check the voltage at the terminals with the engine off and running (should be 12.6V and 13.8–14.4V, respectively).
