Owners Nissan Qashqai (especially models J10 And J11) often encounter a problem when the stove fan stops working. The situation is unpleasant: the cabin is stuffy in the summer, and cold in the winter, despite the heating being on. There can be several reasons for the malfunction - from a banal fuse blown to failure of the motor or climate control unit.

In this article we will analyze all possible reasonswhy isn't the stove blowing? Qashqai, how to diagnose the problem yourself and what to do to fix it. We will separately dwell on the nuances of repairs for different generations of the crossover and give practical advice on prevention.

1. Fan fuse: first check

The simplest and most common reason is blown fuse. B Nissan Qashqai The fuse controls the heater fan F37 (10A) in the cabin mounting block. An additional fuse may be used on climate controlled models. F38 (15A).

Where to look for the mounting block? B Qashqai J10 it is located under the steering wheel on the left, in J11 - behind the decorative cover to the right of the pedals. To check the fuse:

  • 🔧 Turn off the ignition and remove the unit cover.
  • 🔍 Find the fuse by number (the diagram is usually printed on the back of the cover).
  • 💡 Visually inspect the thread - if it is burned out, replace it with a new fuse same denomination.
  • ⚡ If the new fuse immediately blows, look for short circuit in the chain.
⚠️ Attention: Never install a fuse of a higher rating! This may cause the wiring to catch fire. If the fuse blows repeatedly, there is a problem with the wiring or the fan motor.

2. Fan relay: how to check and replace

If the fuse is intact, the next weak point is heater fan relay. B Qashqai it is usually located in additional relay block under the dashboard or next to the mounting block. On models with climate control, the relay can be integrated into the control unit.

Signs of a faulty relay:

  • 🔄 The fan only works at one speed (usually maximum).
  • 🔇 Complete lack of response to changing speeds.
  • 🔥 Extraneous clicks from under the panel when the stove is turned on.

How to check the relay:

  1. Remove the relay (usually R12 or R14 - check the diagram).
  2. Call contacts 85 And 86 (winding) - resistance should be 50–120 Ohm.
  3. Apply 12V to the contacts 85 And 86 - a click should be heard and the contacts should close 30 And 87.

If the relay is faulty, replace it with a new one (part number for Qashqai J10/J11: 25230-4M000 or 25230-4M00A). Cost - from 300 to 800 rubles.

💡

Before replacing the relay, clean the contacts in the block socket from oxidation - this will extend the life of the new relay.

3. Fan motor: diagnostics and repair

If the fuse and relay are good, but the fan does not work, the problem may be the motor itself. B Nissan Qashqai a motor with a commutator motor is used, which wears out over time:

  • 🔥 The armature winding burns out.
  • 🧲 The brushes are worn out.
  • 🛠️ The bearing is jammed.

How to check the motor:

  1. Remove the bottom panel under the glove compartment (you will need a screwdriver T20 and a flathead screwdriver).
  2. Disconnect the power connector from the motor (usually purple and black wires).
  3. Apply 12V directly from the battery to the motor contacts. If it doesn't spin, it's faulty.

Motor repair is possible if the problem is in the brushes or bearing. For Qashqai J10/J11 suitable motor with art. 27300-4M000 or 27300-4M00A. The price of a new one is from 3,500 to 6,000 rubles. When replacing, it is also recommended to clean air channels from dust and leaves.

⚠️ Attention: On models with climate control, after replacing the motor, it may be necessary error reset via a diagnostic scanner (for example, Launch X431 or ELM327).
How to remove the fan motor on a Qashqai J11

1. Remove the glove compartment (4 T20 screws and 2 latches).

2. Unscrew the 3 motor mounting bolts (10mm wrench).

3. Disconnect the connector and remove the motor through the opening under the glove compartment.

4. Installation in reverse order.

4. Fan speed resistor

If the fan only works on maximum speed (4th position), but does not respond to other modes - culprit speed resistor (aka “stove resistance”). This element is responsible for adjusting the speed of the motor.

Where is the resistor located:

  • B Qashqai J10 — under the panel on the driver's side, next to the motor.
  • B Qashqai J11 — behind the glove compartment, on the fan housing.

Signs of a faulty resistor:

  • 🔢 Only 4th speed works.
  • 🔥 The smell of burning from under the panel.
  • 🔄 Spontaneous speed switching.

To check:

  1. Remove the resistor (disconnect the connector and unscrew the 2 bolts).
  2. Check the resistance between the contacts (should be 0.5–5 Ohm depending on the position).
  3. If there is no resistance or infinite, the part is faulty.

Resistor part number for Qashqai: 27350-4M000 or 27350-4M00A. Cost - from 1,200 to 2,500 rubles. Replacement takes 15–20 minutes.

Generation Resistor part number Cost (RUB) Difficulty of replacement
Qashqai J10 (2006–2013) 27350-4M000 1 200–1 800 Average
Qashqai J11 (2013–2021) 27350-4M00A 1 800–2 500 Light
Qashqai J12 (2021–present) 27350-4M010 2 500–3 500 Average

5. Climate control unit (HVAC)

On Nissan Qashqai with climate control (automatic climate) the control unit is responsible for the operation of the fan HVAC (Heating, Ventilation, Air Conditioning). If it fails, the stove may:

  • 🔇 Stop working completely.
  • 🔄 Switch speeds yourself.
  • 🌡️ Incorrect temperature regulation.

Block diagnostics HVAC:

  1. Check the block fuse (F39, 10A).
  2. Remove the block (on J11 it is located behind the center console).
  3. Inspect the board for burnt paths or swollen capacitors.
  4. Connect a diagnostic scanner to check for errors (codes B1420, B1421 indicate a faulty unit).

Unit repair HVAC possible if the problem is in capacitors or soldering. Services charge for this 2,000–4,000 rubles. The new block costs 15,000–25,000 rubles (item: 27800-4M000 for J10, 27800-4M00A for J11).

💡

Before replacing the HVAC unit, be sure to clear errors through the diagnostic scanner, otherwise the new unit may not work correctly.

6. Problems with wiring and connectors

Often the reason for a non-working fan lies in broken wiring or oxidation of contacts. Particularly vulnerable:

  • 🔌 Fan motor connector (oxidation or poor contact).
  • 🔗 Wires from the block HVAC to the resistor.
  • 🔌 Connector for climate control unit (on J11 contacts often come loose).

How to check wiring:

  1. Visually inspect the wires for abrasions or meltdowns.
  2. Test the circuit with a multimeter from the fuse to the motor (the resistance should be close to 0 ohm).
  3. Check the motor ground (usually black wire, attached to the body).

On Qashqai J11 models after 2016, there is often a problem with a broken wire in the corrugation under the pedals - it rubs against the bracket. Solution: lay the wire in additional insulation.

7. Additional reasons: from sensors to clogged filter

If all of the above elements are working, but the heater fan does not work, check:

  • 🌬️ Cabin filter clogged. If the filter is clogged, the motor may overheat and shut down. On Qashqai the filter is located behind the glove compartment (replace every 15,000 km).
  • 🌡️ Interior temperature sensor. If it produces incorrect data, the block HVAC may block fan operation. The sensor is located on the ceiling or in the center console.
  • 🔧 Clogged air ducts. Leaves, dust, or debris may block the fan blades. Cleaning requires removing the panel.

Also on Qashqai J11 with the system NissanConnect There may be malfunctions in the climate control system due to firmware errors. In this case, resetting the settings or flashing the unit will help. HVAC in the service.

FAQ: Frequently asked questions about a non-working heater on a Nissan Qashqai

🔧 The stove fan only works at 4th speed. What is the reason?

Most likely faulty speed resistor (article 27350-4M00A). It is responsible for regulating the speed, and if it fails, only the maximum speed works (supplying voltage directly, without a resistor). Replacement takes 15–20 minutes.

🔇 The stove doesn’t blow at all, but the fuse and relay are intact. What to do?

Check:

  1. Fan motor (supply 12V to it directly).
  2. Wiring from the block HVAC to the motor (especially the ground).
  3. Climate control unit (errors are possible B1420 or B1421).

If the motor does not respond to voltage, it needs to be replaced.

💰 How much does it cost to repair a stove fan at a service center?

The cost depends on the reason:

  • Replacing the fuse/relay - 200–500 rub.
  • Replacing the resistor - 1,500–3,000 rub. (with work).
  • Replacing the motor - 4,000–7,000 rub. (with work).
  • Unit repair HVAC — 3,000–10,000 rub. (depending on the breakdown).
