Heater fan in Nissan Qashqai J10 - a key element of the climate control system, on which not only comfort in the cabin depends, but also driving safety. In winter, a non-working stove leads to fogging of the windows and poor visibility, and in summer it leads to overheating of the interior. Owners J10 (2007–2013) often encounter typical problems: the fan does not turn on, operates jerkily, or makes strange noises. In 80% of cases the fault is worn motor brushes, oxidized resistor contacts or clogged cabin filter.

This article will help you understand the structure of the system, independently diagnose the malfunction and choose the best repair method - from simple cleaning to complete replacement of the fan. We collected data on original part numbers for J10 with engines 1.6 (HR16DE), 2.0 (MR20DE) and diesel 1.5 (K9K), as well as alternative analogues from Bosch, Valeo And Denso. At the end there is an FAQ with answers to frequently asked questions and video instructions from auto electricians.

Design and principle of operation of the heater fan Qashqai J10

Stove fan in Nissan Qashqai J10 is a DC electric motor with a collector unit that pumps air through the heater radiator. Management is carried out through resistor block (on models without climate control) or electronic module (on versions with automatic system). Motor power - 12 V, 25–30 W, rotation speed is adjustable in 4–5 positions.

Key system components:

  • 🔧 Electric motor — main assembly with rotor, stator and brushes (original article number: 27350-JM00A for J10 until 2010, 27350-JM01A for restyling).
  • 🔄 Resistor block — is responsible for changing the rotation speed (article: 27300-JM00A).
  • 🌡️ Interior temperature sensor — transmits data to the climate control unit (if installed).
  • 🔌 Fuse F35 (10A) — protects the fan circuit (located in the mounting block under the steering wheel).

On versions with climate control (optional HAA in VIN) control is carried out through automatic control unit (item: 27310-JM00A). In such machines, the fan may turn on on its own when the engine starts - this is normal system behavior.

Signs of a malfunctioning stove fan

The first symptoms of fan problems are often ignored until the system fails completely. Pay attention to the following signals:

Symptom Probable Cause Urgency of repair
The fan does not turn on at any speed Fuse blown, circuit broken, motor faulty ⭐⭐⭐⭐⭐
Only works at 4th speed The resistor block has failed ⭐⭐⭐⭐
Noise, grinding or vibration during operation Bearing wear, debris entering the impeller ⭐⭐⭐
Spontaneous shutdown Poor contact in connectors, winding overheating ⭐⭐⭐⭐

If the fan does not respond to gear changes, check the fuse first F35 in the mounting block. On Qashqai J10 it is located to the left of the steering column under a plastic cover. Also inspect the relay K35 — it is responsible for supplying power to the engine.

⚠️ Attention: On machines with climate control, if the fan fails, an error may appear on the panel BLINK CODE 21 (motor circuit malfunction). In this case, diagnostics with a scanner is required. Consult-III or analogue.

Fault diagnosis: step-by-step instructions

To check the heater fan for Nissan Qashqai J10 you will need: a multimeter, a screwdriver with a Phillips bit and a flashlight. Start with a visual inspection:

  1. Checking the fuse and relay

    Open the mounting block under the steering wheel and find the fuse F35 (10A) and relay K35. Remove them and inspect them for melting. Check the continuity of the circuit with a multimeter in continuity mode.

  2. Fan connector voltage test

    Remove the connector from the engine (located under the glove compartment on the passenger side). With the ignition on and 4th speed selected on the contacts 1 (+12V) And 2 (mass) there must be tension. No power indicates a broken wire or a faulty resistor.

  3. Checking the resistor block

    On models without climate control, the resistor is located next to the fan. If speeds 1–3 are not working (but the 4th is working), the unit must be replaced. Original article: 27300-JM00A, analogue from Febi — 27300.

☑️ Qashqai J10 fan diagnostics

Done: 0 / 5

If the fan motor does not show signs of life even when directly connected to the battery (12V to the contacts 1 And 2), it needs to be replaced. On Qashqai J10 Since 2010, motors with improved brushes have been installed (article no. 27350-JM01A), which last longer.

How to check fan brushes without disassembling?

If, when voltage is applied, the motor briefly “jerks” but does not rotate, this is a sign of wear on the brushes. In 90% of cases, replacing brushes (part number 27355-JM000) restores functionality.

Heater Fan Replacement: Step-by-Step Guide

To replace the fan with Nissan Qashqai J10 you will need:

  • 🔧 Screwdriver T20 and Phillips PH2;
  • 🔨 Flat screwdriver for removing clips;
  • 🧲 Magnet for fastening (so as not to lose bolts in the cabin);
  • 🧹 Vacuum cleaner for cleaning air ducts.

Opening hours: 1.5–2 hours (no experience required). The main difficulty is access to the motor, which is located behind the glove compartment.

  1. Removing the glove compartment

    Unscrew the 3 bolts securing the glove compartment (two from the bottom and one from the top under the plastic plug). Carefully pull it out, disconnecting the backlight connector.

  2. Air duct dismantling

    Unscrew the 2 bolts securing the air duct to the heater body (T20). Remove the pipe leading to the passenger's feet.

  3. Removing the Fan

    Disconnect the power connector. Unscrew the 3 bolts securing the motor (PH2) and pull it out along with the impeller. Be careful - dirt can accumulate in the air ducts!

  4. Installing a new fan

    Before installation, clean the mounting area from dust. Install a new motor (original or analogue from Valeo 698733) and reassemble everything in reverse order.

💡

When assembling, lubricate the rubber seals of the air ducts with silicone grease - this will prevent squeaks and whistles when the stove is operating.

⚠️ Attention: On diesel versions Qashqai J10 (engine K9K) the fan has a reinforced design due to increased loads. Install only original parts or certified analogues from Denso (article DMT0125).

Selection of spare parts: original vs analogues

The cost of the original heater fan for Nissan Qashqai J10 is 8,000–12,000 ₽ (depending on the year of manufacture). However, there are high-quality analogues on the market that are cheaper:

Manufacturer Article Price, ₽ Features
Nissan (original) 27350-JM01A 10 500 2 year warranty, suitable for restyling
Valeo 698733 5 200 Long brush life, quiet operation
Denso DMT0125 6 800 Reinforced design for diesel engines
Bosch 0 352 019 035 4 700 Budget option, average resource

When choosing an analogue, pay attention to connector polarity - on Qashqai J10 Until 2010, a connector with straight contacts was used, after that - with curved ones. Also check the contents: in some sets (for example, Febi 27350) the impeller comes separately.

💡

Saving on cheap analogues often results in repeated repairs after 1–2 years. Optimal balance of price and quality - Valeo or Denso.

Prevention and extension of fan service life

Average heater fan life per Nissan Qashqai J10 — 100,000–150,000 km. To make it work longer:

  • 🌿 Change the cabin filter every 15,000 km (article: 27277-JM00A). A clogged filter increases the load on the motor.
  • 💧 Avoid moisture penetration — after washing, check the drain holes under the windshield.
  • 🔌 Clean your contacts resistor block once a year (use WD-40 or Liqui Moly Kontakt 61).
  • ⚡ Avoid long hours of work at maximum speed - this reduces the life of the brushes.

On versions with climate control, it is recommended to carry out damper calibration. To do this:

  1. Turn on the ignition.
  2. Press and hold the button RECIRC (recirculation) 10 seconds.
  3. Wait for the beep and the system will perform a self-test.

If the fan starts to jam, try lubricating the bearings with silicone grease (for example, Molykote 3452). To do this:

  1. Remove the impeller from the motor shaft.
  2. Place 2-3 drops of grease into the bearing gaps.
  3. Rotate the shaft by hand to ensure even distribution.

Common repair mistakes and how to avoid them

Even experienced car owners make mistakes when replacing a fan with Qashqai J10. Here are the most common:

  1. Incorrect duct assembly

    If the pipes are installed skewed, whistles and loss of performance occur. Check the connections for tightness after assembly.

  2. Ignoring cleaning the heater core

    When replacing the fan, it is recommended to flush the heater radiator (part number: 27100-JM00A) means Liqui Moly Kuhler-Reiniger. A clogged radiator reduces heating efficiency by 30–40%.

  3. Buying an incompatible analogue

    For example, a fan from Nissan X-Trail T31 (article 27350-3M50A) is similar in appearance, but has a different rotation speed. Use only parts specified in the catalog ETKA for J10.

⚠️ Attention: After replacing the fan on versions with climate control, you may need to reset errors via the diagnostic connector. Use a scanner Launch X431 or similar by selecting HVAC Reset.

FAQ: answers to frequently asked questions

Is it possible to repair the fan brushes or just replace them?

Brushes can be replaced separately (article no. 27355-JM000), but this requires disassembling the motor and soldering the contacts. In 70% of cases, it is cheaper to buy a new motor, since wear of the brushes is accompanied by wear and tear of the commutator.

Why does the fan only work at speed 4?

This is a typical sign of a faulty resistor block (part number 27300-JM00A). At speed 4, power is supplied directly, bypassing the resistor. Replacing the block solves the problem in 95% of cases.

How to remove the impeller from the fan shaft?

The impeller is secured to the shaft using a retaining ring. To remove it:

  1. Pry up the ring with a thin screwdriver.
  2. Pull the impeller towards you, rocking it from side to side.
  3. If necessary, heat the seat with a hairdryer (not higher than 60°C).

How much does it cost to replace a fan at a service center?

Cost of work in car services in Moscow and the regions:

  • Diagnostics: 500–1,000 ₽;
  • Fan replacement: RUB 2,500–4,000;
  • Replacement of the resistor block: 800–1,500 ₽.

Total with spare parts: from 7,000 to 15,000 ₽.

Where is the fan fuse on Qashqai J10?

fuse F35 (10A) located in the mounting block under the steering wheel, to the left of the column. To access:

  1. Unscrew the 2 screws securing the plastic cover (PH2).
  2. Remove the cover by pulling it down.
  3. The fuse is the fifth one from the top in the left row (there is a diagram on the cover).
