Heater in Nissan Juke - a critically important unit, especially in Russian winter conditions. When the heater motor starts to malfunction, the driver faces not only discomfort, but also the risk of the windows fogging up, which directly affects safety. In 80% of cases, the problem is solved by replacing the fan motor, but many car owners put off repairs for fear of disassembling the interior.
In practice, the procedure for replacing the heater motor with Juke (including restyled versions F15 And K13) takes 2–3 hours with proper preparation. In this article we will analyze exact signs of malfunction, detailed instructions with photos, as well as the nuances of choosing spare parts - from original articles to proven analogues. We will pay special attention to typical errors that lead to repeated repairs after 1–2 months.
Signs of a malfunctioning heater motor
The first symptoms of a heater motor failure are often attributed to a clogged cabin filter or problems with the electronics. However there is 5 Key Signs, which directly indicate wear on the electric motor:
- 🔊 Extraneous sounds - creaking, squealing or knocking when the stove operates at any speed. Most often caused by worn bearings or debris getting into the impeller.
- 🌀 Uneven air flow — the air flows in jerks even at maximum fan speed, which indicates problems with the brushes or windings.
- 🚫 Failure of one or more speeds - if the stove only works in mode 3-4, the resistor or motor is to blame (in 60% of cases it’s the motor).
- 🔥 Burning smell - when the winding overheats or the shaft is jammed. Ignoring this symptom may result in a wiring fire!
- ❄️ Complete absence of airflow - if even at maximum speed the air does not flow, and the fuse
F30 (10A)intact, the motor needs to be replaced.
On Nissan Juke In the first years of production (2010–2013), brush wear is more common, and on models after 2014, problems with bearings occur. You can check the motor without disassembling it: turn on the heater and lightly tap the heater housing on the passenger side - if the fan starts working briefly, the problem is definitely in the engine.
⚠️ Attention: If the fuse trips when you turn on the stove F30, under no circumstances install a “bug” or a fuse of a higher rating! This could burn out the climate control unit (BCM).
Selection of spare parts: original vs analogues
Original heater motor for Nissan Juke has an article number 27350-JM00A (until 2014) and 27350-JM00B (after restyling). The cost of a new unit from a dealer is from 8,000 to 12,000 rubles. However, there are proven analogues that will cost less:
| Manufacturer | Article | Price, ₽ | Features |
|---|---|---|---|
| Nissan (original) | 27350-JM00B |
8 000–12 000 | 12 month warranty, fully compatible |
| Valeo | 698583 |
4 500–6 000 | The quality is not inferior to the original, often installed on the conveyor |
| Denso | 727-0121 |
5 000–7 000 | Japanese production, resource higher than the original |
| Febi | 35600 |
3 200–4 500 | Budget option, suitable for temporary replacement |
When choosing an analogue, pay attention to connection polarity — on some Chinese motors the wires are swapped, which leads to the impeller rotating in the opposite direction. Also check the package: the original set includes an O-ring (27355-JM000), which is often lost during disassembly.

Tools and preparation for replacement
To replace the heater motor with Nissan Juke No specialized equipment is required, but some tools are indispensable. Here's the full list:
- 🔧 A set of sockets and a ratchet wrench (the head must be on
10 mmAnd8 mm). - 🔨 Plastic spatulas for removing cladding (so as not to damage the clips).
- ⚡ Multimeter to check the voltage at the motor connector.
- 🧲 Magnetic holder (makes it easier to work with small bolts in hard-to-reach places).
- 🧴 Silicone grease for the O-ring (e.g. Liqui Moly Silicon-Fett).
Before starting work necessarily:
- Disconnect the negative terminal of the battery (to avoid short circuit).
- Place the steering wheel and seat in the highest position for easy access.
- Prepare your work area - arrange the parts in the order they were removed (for example, use a box with partitions).
⚠️ Attention: On models with climate control (automatic climate) after disconnecting the battery, you will need to reset errors via a diagnostic scanner (for example, Launch X431). Without this, the stove may not turn on!
☑️ Preparing to replace the stove motor
Step-by-step replacement instructions
The process of replacing the heater motor with Nissan Juke includes front panel disassembly. The main difficulty is access to the heater housing, which is hidden behind the glove compartment. Follow the instructions exactly step by step to avoid damaging the plastic clips.
Step 1: Removing the glove compartment and trim
1. Open the glove compartment and unscrew the two bolts at the top (under the plastic plug).
2. Press the side walls of the glove compartment inward - it will come out of the grooves.
3. Disconnect the backlight connector (if equipped) and move the glove compartment to the side.
4. Remove the center console trim, starting from the bottom (carefully pry up the plastic clips with a spatula).
Step 2: Accessing the Heater Motor
1. Behind the glove compartment you will see a black plastic heater housing. The motor is located at the bottom.
2. Unscrew the 3 motor mounting bolts (two on top and one on bottom).
3. Disconnect the power connector. Before removing, take a photo of the location of the wires!
4. Carefully pull out the motor along with the impeller (you may need to turn it counterclockwise).
Step 3: Installing a New Motor
1. Transfer the impeller from the old motor to the new one (if it is in good condition).
2. Check the O-ring - replace it if necessary (27355-JM000).
3. Install the new motor in reverse order, making sure the impeller rotates freely.
4. Connect the connector and check the operation of the stove at all speeds before final assembly!
If after replacement the heater only works at 4th speed, check the heater resistor (27380-JM00A) - it is located next to the motor and often fails in parallel.
What to do if the new motor does not work?
Check fuse F30 (10A) in the block under the hood. Make sure that the connector is connected correctly (on some analogues the polarity is reversed). If the motor hums but does not rotate, the impeller may be jammed - try turning it by hand.
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes when replacing a heater motor with Nissan Juke. Here are the most common mistakes and their consequences:
- 🔌 Incorrect connector connection — leads to rotation of the impeller in the opposite direction (the stove blows cold air even at maximum airflow).
- 🔧 Re-tightening of fastening bolts - may deform the heater housing, causing vibration and noise.
- 🧹 Ignoring case cleaning — accumulated dirt and leaves inside the heater reduce the life of the new motor by 30–40%.
- 🔋 Forgetting to reset climate control errors — on cars with an automatic system, the stove may not turn on without diagnostics.
To avoid problems, after installing a new motor:
- Check the operation of the stove at all speeds before assembling the cladding.
- Make sure that the impeller does not touch the housing (there should be a gap of 1–2 mm).
- Apply silicone grease to the O-ring for a seal.
If after replacing the motor the stove is noisy at high speeds, check the balancing of the impeller. Often the problem is solved by cleaning it from dust or replacing it with a new one (part number 27352-JM000).
Cost of service replacement vs self-repair
The price of replacing a heater motor at a car service depends on the region and level of the service station. In Moscow and St. Petersburg, the work will cost 3,500–5,000 rubles, in the regions - from 2,000 to 3,500 rubles. Total with spare part:
| Option | Spare part cost, ₽ | Cost of work, ₽ | Total, ₽ |
|---|---|---|---|
| Original + service | 8 000–12 000 | 3 500–5 000 | 11 500–17 000 |
| Analogue (Valeo) + service | 4 500–6 000 | 3 500–5 000 | 8 000–11 000 |
| Self-replacement (original) | 8 000–12 000 | 0 | 8 000–12 000 |
| Self-replacement (analog) | 3 200–6 000 | 0 | 3 200–6 000 |
Self-repair saves up to 50% of the budget, but requires care. The main risk is damage to the plastic cladding clips, which are on Juke fragile and cost from 200 rubles apiece. If you've never disassembled a dashboard, practice removing the glove compartment - this is the most difficult part of the process.
Savings on service work are justified only with careful preparation. If you are not confident in your abilities, it is better to entrust the replacement to professionals - mistakes when disassembling the interior can be more expensive.
Prevention: how to extend the life of a stove motor
Average lifespan of the heater motor Nissan Juke - 100,000–150,000 km, but with proper care this period can be increased by 1.5–2 times. Here 5 simple rules:
- 🌿 Change the cabin filter every 15,000 km — a clogged filter increases the load on the motor.
- 🚿 Avoid high-pressure engine washing — water entering the heater housing causes corrosion of the bearings.
- 🔄 Regularly turn on the stove at maximum speed - this prevents the brushes from sticking.
- 🧴 Treat the O-ring with silicone lubricant every time you remove the motor.
- 🔍 Check the voltage at the connector at the first sign of a malfunction - low voltage (less than 11 V) accelerates wear.
If you often drive on dusty roads, install additional zero resistance filter (For example, K&N) or a mesh on the air intake of the stove. This will reduce the entry of abrasive particles into the impeller.
FAQ: Frequently asked questions about replacing the heater motor
Is it possible to repair an old motor instead of replacing it?
Theoretically, yes - if the problem is in the brushes or bearings. However, on Nissan Juke The motor is non-separable (the body is sealed), so repairs require sawing and subsequent soldering. In 90% of cases this is unprofitable - it’s cheaper to buy a new one.
Why does the stove only work at 4th speed after replacement?
This indicates a malfunction heater resistor (27380-JM00A). It is responsible for adjusting speeds and often fails in parallel with the motor. Replacing the resistor takes 10 minutes and will cost 1,500–2,500 rubles.
Do I need to remove the dashboard to replace the motor?
No, complete dismantling of the panel is not required. It is enough to remove the glove compartment and part of the trim on the passenger side. On some versions Juke It may be necessary to remove the glove box completely.
How to check the heater motor without removing it?
Connect the multimeter in voltmeter mode to the motor connector (pins 1 and 2). When the stove is turned on at maximum speed, the voltage should be 12–14 V. If there is voltage, but the motor does not work, it is faulty. If there is no voltage, the problem is in the wiring or control unit.
What motors are suitable for other Nissan models?
On Juke motors from Nissan Micra K13 (article 27350-JM00A) and Renault Captur (article 27350-5M50R). However, the power connectors may differ - you will need to resolder or replace the chip.
