Owners Nissan Tiida (especially the first generation C11 and restyled version C13) often encounter the problem of a non-working heater. In 80% of cases, the culprit is a faulty stove motor, which is responsible for air circulation in the cabin. If you notice that the stove is blowing weakly, making strange noises or does not turn on at all, itβs time to start diagnosing and replacing it.
This article will help you figure out how replace the heater motor on a Nissan Tiida yourself without contacting the service. We will consider in detail the reasons for the breakdown, the choice of spare parts (original vs analogue), step-by-step instructions with photos and videos, and also give tips on prevention. Even a beginner can cope with the task - the main thing is to follow the algorithm and take your time.
Signs of a malfunctioning heater motor
Before proceeding with the replacement, it is important to make sure that the problem is in the motor and not in the fuse, resistor or control unit. Pay attention to the following symptoms:
- π Extraneous sounds (grinding, squealing, knocking) when the stove operates at any speed. This indicates bearing wear or debris has entered the impeller.
- π¨ Weak air flow even at maximum fan speed. Often accompanied by a burning smell - a sign of a burning winding.
- β The stove doesn't turn on at all. Check the fuse
F30 (10A)in the mounting block - if it is intact, the problem is in the motor or resistor. - π Works only at 3-4 speeds. This is a typical sign of a problem heater resistor, but sometimes the motor itself is to blame.
If you observe at least one of these symptoms, it's time to move on to diagnosis. On Nissan Tiida The heater motor is located under the dashboard on the passenger side. Access to it is difficult, but possible without removing the instrument panel - more on this in the next section.
- Extraneous noise
- Weak air flow
- The stove does not turn on
- Only works at maximum speed
Choosing a stove motor: original or analogue?
When purchasing a new heater motor for Nissan Tiida you have two options: original spare part or analogue. Let's look at the pros and cons of each.
| Part type | Article | Price, β½ | Pros | Cons |
|---|---|---|---|---|
| Original (Nissan) | 27350-4M000 or 27350-4M00A |
8 000β12 000 | Guaranteed quality, long service life, perfect compatibility | High price, possible fakes |
| Analogue (Valeo) | 717003 |
4 500β6 000 | Good quality, affordable price, widely available in stores | There may be defective copies |
| Analogue (Denso) | 727-1001 |
5 000β7 000 | Reliable brand, durability | Less common on sale |
| Budget analogue (ERA) | 550402 |
2 500β3 500 | Low price, fast delivery | Low resource, possible noise problems |
Our advice: if your budget allows, choose original or Valeo/Denso. Cheap analogues often fail after 1β2 years, and their noise can exceed the original. When purchasing, be sure to check the article number and warranty.
β οΈ Attention! On Nissan Tiida after 2010 release (restyling), a motor with a different connector can be installed. Check the year of manufacture of your car before purchasing.
Preparing for replacement: tools and safety
To replace the heater motor with Nissan Tiida you will need:
- π§ Tools: 10 mm socket, extension, ratchet handle, screwdriver with Phillips bit, pliers.
- π Additionally: flashlight, mirror on a telescopic handle (for inspecting hard-to-reach places), multimeter (for checking voltage).
- π Terms: flat area, disconnected battery (remove the negative terminal!), warm garage (plastic becomes brittle in winter).
Before starting work be sure to disconnect the battery - this will prevent a short circuit if the wiring is accidentally touched. We also recommend removing glove compartment And passenger side lower panel - this will make it easier to access the motor.

Check the operation of the stove at all speeds (for diagnostics) -->
If you have never worked with car electrics, watch the video instructions for disassembling the panel Nissan Tiida - this will help avoid mistakes. For example, many people forget to disconnect the glove compartment light connector, which leads to broken wires.
Step-by-step instructions for replacing the heater motor
Now let's move on to the process itself. Follow the instructions carefully - every step is important!
- Removing the glove compartment and lower panel
Unscrew the 4 screws securing the glove compartment (2 on the bottom and 2 on the inside) and carefully remove it, disconnecting the backlight connector. Then remove the lower plastic panel under the dashboard - it is secured with 2 10 mm bolts and 3 latches.
- Access to the motor
The heater motor is located in a plastic housing behind the center console. You need to disconnect the power connector (press the latch and pull it down) and unscrew the 3 motor mounting bolts (10 mm head).
- Removing the old motor
Carefully remove the motor from the housing by turning it counterclockwise. Be careful - there may be sharp blades on the impeller! Inspect the cabinet for debris or damage.
- Installing a new motor
Place the new motor into the housing, aligning the grooves, and secure with bolts. Connect the power connector and check the operation of the stove at all speeds before assembly!
- Reassemble in reverse order
Reinstall the lower panel and glove compartment. Check that all latches and connectors are connected correctly.
The whole process takes about 1.5β2 hours. If you encounter difficulties during the dismantling stage, watch the video below - all the nuances are shown there:

β οΈ Attention! When installing a new motor Do not use force when turning the impeller by hand - this may damage the bearings. Check rotation only after connecting power.
Common mistakes and how to avoid them
Even experienced car owners sometimes make mistakes when replacing the heater motor. Here are the most common of them:
- β‘ Undisconnected battery. This is fraught with a short circuit when the wiring is touched. Always remove the terminal before work!
- π§ Overtightened mounting bolts. The plastic motor housing may crack if the bolts are tightened with force. A little effort is enough.
- π Incorrect connector connection. If the stove only operates at speed 4, check whether the connector on the motor is tightly seated.
- ποΈ Ignoring debris in the case. Dust and leaves in the air duct can quickly damage the new motor. Blow out the housing with compressed air before installation.
Another typical problem is buying the wrong motor. On Nissan Tiida Before and after 2010, motors with different connectors were installed. Check the year of manufacture of your car and check the article numbers!
If after replacing the motor the stove still only works at maximum speed, the problem is stove resistor (article 27355-4M000). It is located next to the motor and can be changed in 10 minutes.
Prevention: how to extend the life of a stove motor
To make your new heater motor last longer, follow these tips:
- π Change the cabin filter regularly (every 15,000 km). A clogged filter increases the load on the motor.
- πΏ Clean your air ducts periodically. Use a vacuum cleaner or compressed air to remove dust and leaves.
- βοΈ Do not turn on the stove at maximum in cold weather. Sudden temperature changes can damage plastic parts.
- π§ Check the fuse
F30once a year. Its burnout is often disguised as a motor malfunction.
Also avoid long-term operation of the stove at maximum speed - this reduces the life of the motor. If you need to warm up the interior quickly, use the air recirculation mode.
Timely replacement of the cabin filter and cleaning of the air ducts increases the service life of the heater motor by 2-3 times!
