Stove fan in Nissan Qashqai - a key element of the heating system, on which not only comfort in the cabin depends, but also safety in the winter. If the airflow suddenly stops working, the problem most often lies in a blown fuse. However, not all owners know where exactly it is located, what the rating should be and how to replace it correctly without the risk of damaging the car’s electrical system.
In this article we will look at all generations of Qashqai (J10, J11, J12), we will indicate the exact location of the fuses, tell you about the typical reasons for their failure and give step-by-step instructions for replacement. You will also learn how to check a fuse without a multimeter and what to do if replacing does not solve the problem. The information is relevant for petrol and diesel versions, including models with climate control.
Where is the heater fan fuse located? Nissan Qashqai
Depending on the generation and configuration of the car, the fuse may be located in different blocks. On Qashqai J10 (2006–2013) And J11 (2013–2021) he is usually in interior mounting block, which is located to the left of the steering column, behind the plastic cover. On Qashqai J12 (from 2021) The diagram may differ - here the fuse is sometimes placed in the engine compartment.
To accurately determine the location, pay attention to the markings:
- 🔧 J10 (dorestyle/restyle): fuse
F37 (10A)orF38 (15A)in the cabin block; - 🔧 J11 (until 2017):
F40 (15A)in the cabin unit, next to the fan relay; - 🔧 J11 (after 2017) and J12: maybe
F20 (20A)in the engine compartment (next to the battery).
Important: on vehicles with climate control there may be an additional fuse for the control unit (F10, 7.5A), which also affects the operation of the fan. If the heater does not turn on at all speeds, check both elements.

Incorrect fuse rating selection may result in fire in electrical wiring or failure of the stove controller. The table below shows verified data for different versions Qashqai:
| Generation | Year of manufacture | Fuse number | Rating (A) | Location |
|---|---|---|---|---|
| J10 (dorestyle) | 2006–2010 | F37 | 10 | Cabin block (left) |
| J10 (restyle) | 2010–2013 | F38 | 15 | Cabin block (left) |
| J11 (until 2017) | 2013–2016 | F40 | 15 | Cabin block (under the glove compartment) |
| J11 (after 2017) | 2017–2021 | F20 | 20 | Engine compartment block |
| J12 | from 2021 | F25 | 20 | Engine compartment (next to the battery) |
⚠️ Attention: On diesel versions Qashqai J11 with engine 1.5 dCi The fan fuse may be rated 25A (designation F42). Check this information in your car's manual or on the cover of the mounting block.
Causes of blown heater fan fuse
If a fuse blows again after replacement, this indicates a more serious problem in the electrical circuit. Main reasons:
- ⚡ Short circuit in the wiring - most often occurs due to frayed wires under the dashboard or in the area of the pedal assembly. Check the harnesses for exposed areas.
- 🌀 Stuck fan motor - if the bearings are worn out, the current consumption increases sharply, which leads to the fuse burning out. Symptom: before failure, the stove was operating with extraneous noise.
- 🔌 Oxidized contacts in the connectors of the fan or control unit. This increases resistance and heat in the circuit.
- 🔥 Faulty relay (if it is in the circuit) - can cause current surges. On Qashqai J10 The fan relay is usually located next to the fuse
F37/F38.
💡 Helpful tip: If the fuse blows immediately after installation, do not try to install a higher rated element (for example, 20A instead of 15A). This may lead to melting of wiring or failure of the stove controller (repair cost - from 15,000 ₽).
How to check wiring for short circuit without a multimeter?
Disconnect both heater fan connectors and replace the fuse. If it doesn't burn out, the problem is in the motor. If it burns out, look for a short in the wiring between the fuse box and the fan.
Step-by-step instructions for replacing the fuse
To replace you will need:
- 🔧 Flat screwdriver (for removing the block cover);
- 🔍 Flashlight (to see the markings);
- 🔋 New fuse of the required rating;
- 🧤 Gloves (optional to avoid leaving fingerprints on the contacts).
Algorithm of actions:
- Turn off the ignition and remove the key from the lock. This is mandatory to avoid short circuits when manipulating the block.
- Remove the mounting block cover:
- On J10/J11 - use a screwdriver to pry it off on the left side and pull it towards you.
- On J12 - unscrew two screws
Torx T20in the engine compartment.

How to check a fuse without a multimeter
If you don’t have a tester at hand, you can use the visual method or “diagnosis” using a light bulb. Here are 3 reliable ways:
- Visual inspection:
A blown fuse usually has broken thread inside or blackened body. However, some models (especially glass ones) may look intact even if broken - in this case, additional checking will be required.
- Checking for spark:
Insert the fuse into the socket and turn on the stove. If it immediately burns out with a characteristic crackling sound, there is a short circuit in the circuit. Don't try again - this may damage the control unit.
- Using the warning light:
Take any 12-volt light bulb (for example, from the dimensions) and two wires. Connect one wire to ground, and the second one in turn to the fuse contacts with the ignition on. If the light comes on on both contacts, the fuse is good. If only on one, it burned out.
If you don't have a light bulb at hand, you can use an LED with a 1 kOhm resistor. It glows even at low current, which will help more accurately diagnose a break.
What to do if replacing the fuse does not help
If after replacing the fuse the heater fan still does not work, the problem may lie in the following components:
- 🔄 Fan relay - on Qashqai J10 it often fails along with the fuse. The relay is usually located nearby in the same block (designation
R15orBlower Relay). - 🛠️ Fan motor - if it does not spin even when directly connected to the battery (12V to the contacts), replacement is required. The cost of a new motor is from 3,500 ₽.
- 📱 Stove control unit - on Qashqai J11 with climate control, the transistor in the module often fails. Diagnosed only by the scanner (error
B14XX). - 🔌 Broken wiring - Check the circuit from the fuse box to the motor. Often the wires fray in the corrugation under the dashboard.
⚠️ Attention: On Qashqai J11 with the system Nissan Connect A fan malfunction may block access to climate settings via the multimedia screen. In this case, a system reset is required (hold the Power 10 seconds).
If the stove only works at 4th speed, the problem is in the speed resistor (part for 800–1,200 ₽). On Qashqai J10 it is located under the glove compartment, on J11 - behind the center console.
Typical mistakes when replacing a fuse
Even experienced car owners sometimes make mistakes that lead to repeated breakdowns. That's what can't do:
- ❌ Install a bug (a wire instead of a fuse). This may lead to wiring fire, especially on Qashqai with a lot of electronics.
- ❌ Use a higher rated fuse. For example, put
20Ainstead of15A. This will temporarily solve the problem, but will increase the risk of damage to the heater controller. - ❌ Ignore motor check after the fuse has blown again. In 70% of cases it is he who is to blame.
- ❌ Close the fuse box with exposed contacts. This may cause a short circuit due to vibration.
🔧 Practical advice: If you frequently experience blown fan fuse, install in the circuit additional relay (for example, from an alarm). This will reduce the load on the standard fuse and extend its life.
FAQ: Frequently asked questions about the heater fuse Nissan Qashqai
Is it possible to drive without a heater fan fuse?
No, it's dangerous. Without a fuse, any short circuit in the fan circuit may cause a fire. In addition, on Qashqai J11 without a working stove an error may occur P0500 (speed sensor malfunction), since the engine control unit receives data on the air speed in the cabin.
Why does the fuse only blow at 3rd and 4th speed?
This is a sign of a problem speed resistor or oxidation of its contacts. At low speeds the current passes through the resistor, and at high speeds it passes directly. If the fuse burns only at maximum modes, check the circuit without a resistor (direct connection to the motor).
Where to buy an original fuse for Qashqai?
Original fuses Nissan sold at dealerships (item number for 15A — 28511-JD00A). However, high-quality analogues from Bosch, Hella or Littlefuse. The main thing is to observe the denomination and type (knife, miniature).
Can the heater fuse affect the operation of the air conditioner?
Yes, on Qashqai J11 with climate control fan fuse (F40) also powers the air conditioning compressor control circuit. If it is burned out, the air conditioner may not turn on or operate jerkily.
How often should fuses be checked? Nissan Qashqai?
A preventative check is recommended every 30,000 km or at the first sign of electrical failure. Pay special attention to fuses after washing the engine compartment - moisture can cause corrosion of the contacts.
