How to replace a Nissan Qashqai heater motor

Replacing the Nissan Qashqai heater fan may be required due to mechanical and electrical damage. Some of them can be corrected by replacing individual elements of the mechanism, and in some cases it will be necessary to install a new fan assembly. Next, we will consider the possible causes of failure of the heating system motor and options for eliminating them. We will also present a list of spare parts that can be used to replace the fan and its individual elements on a Nissan Qashqai.

The interior of the updated (below) 2010 Qashqai is practically no different from the pre-restyling (above)

Problems and reasons

We have been hearing about stove malfunctions in this Qashqai for a long time.

Three main symptoms of malfunction:

the stove does not blow (does not heat), the stove does not change speed or makes extraneous sounds (whistles, squeals, squeaks).

The main culprits for these symptoms are:

1. The stove motor does not blow:

the brushes are worn out/the lamellas are worn out/the winding is burnt out - change the motor or the transistor is burnt out - change the transistor or the thermal fuse in the transistor block is burnt out - change the thermal fuse.

2. The stove motor does not change the rotation speed:

The transistor is burnt out - change the transistor.

3. The stove motor squeals:

The bushings are worn out - change the motor. I don’t recommend changing bushings for bearings - there are a lot of difficulties, the result is not very good.

Price issue

And although the procedure for replacing a heating system motor is not particularly complicated, not every motorist can cope with such a task. Therefore, many vehicle owners have to pay for such a service. If you decide to seek help from a service station, then you will probably be interested in learning about the cost of the service. Depending on the region of residence, it may differ radically. For example, if in Moscow you pay from 4,500 to 6,500 rubles to replace a motor, then somewhere in Rostov or Nizhny Novgorod this procedure will cost from 1 to 4 thousand rubles.

Detailed instructions for dismantling the electric motor, as well as troubleshooting the system, are given in the video below (author - Nadezhda HE).

A very small number of cars can be called ideal and perfect, without flaws or weaknesses. The Nissan Qashqai cannot be classified as such a car, since the weak point in this car is the interior heating system. It is not reliable, it often breaks down and, as you might have guessed, this happens at the most inopportune moments. Of all the breakdowns associated with the Qashqai stove, we have identified the three most common:

1. The Nissan Qashqai heater motor does not blow due to worn brushes, lamellas or burnt windings. All these faults can be eliminated by repairing the stove motor. Also, the reason for this behavior of the system may be a burnt thermal fuse, which cannot be repaired, so it will have to be replaced with a new one.
2. The absence of changes in the rotation speed of the motor indicates a faulty transistor.
3. Replacement of the motor is required if extraneous sounds occur during its operation. This situation occurs due to worn bushings. Theoretically, they can be replaced with bearings, but this will not ensure quiet operation of the stove, and there are many difficulties.

The Nissan Qashqai heater motor can ruin your life by breaking down at the most inopportune moment and it is better to be prepared for this.

Qashqai heater electric motor repair

Replacing the Nissan Qashqai heater fan is not the only solution. You can try to repair the faulty element. The procedure for removing the fan remains identical to that described in paragraph “Step-by-step description of replacing the heater motor.” After removing it, you can see the accumulation of dust. Clogging can cause the impeller to jam. To perform an audit, you must perform the following operations:

1. To dismantle the impeller, unscrew the upper fixing nut;
2. The internal cavity of the impeller is cleaned from dust deposits;
3. Deposits of dust and dirt particles on the upper and lower parts of the motor bushing are removed with a brush or brush;
4. Subsequently, the condition of the brush-contact apparatus is monitored. If the brushes are worn, they must be replaced;
5. The lock washers and others following them are removed from both sides of the electric motor shaft, then the fan axis is dismantled;
6. At this stage, the condition of the bearings is checked, check for play, hum or increased noise during rotation. If any suspicion arises, the bearing must be replaced. To do this, you will need to bend the three retaining petals, dismantle the failed element and install a new one;
7. In the future, we assemble the electric motor in the reverse order. At the same time, we lubricate the rubbing parts of the mechanism.

Spare parts for repair and replacement

As we have already figured out earlier, there can be many reasons why the Qashqai stove fan does not work. In case of a complete replacement of the entire assembly, you will need to know which spare parts are suitable for the Nissan Qashqai. When replacing individual elements of a mechanism, you will first need to correctly determine the cause of the damage. And then move on to selecting the appropriate spare part. The price of an assembled stove fan or its individual components depends on the supplier.

For Nissan Qashqai, you can use original electric motors, which are supplied in a housing and with an impeller. Articles:

• 27225-ET00A;
• 27225-JD00A;
• 27225-ET10A;
• 27225-ET00B;

Why you may need to replace the Nissan Qashqai heater motor

Operating a car in winter with a non-working heater often not only causes discomfort, but becomes almost impossible. Especially when it comes to long trips. Let's look at several common malfunctions of the interior heater on a Nissan Qashqai.

1. Weak hot air flow. This problem occurs most often, and there can be several reasons for its occurrence. One of the most common causes of this phenomenon is insufficient rotation speed of the stove motor. The motor may not operate at full power due to a malfunction in it or due to a malfunction in the speed controller. The second common cause of this phenomenon is clogging of air lines or fan blades with dust and other foreign materials. Sometimes the fan blades are damaged or the fan is not seated correctly on the output shaft of the electric motor.
2. Not hot enough or completely cold air. There are two main reasons here. The first is a problem with the heater core. It can become clogged both outside and inside. Sometimes, due to problems with the engine, the radiator of the stove becomes airy. The second is a breakdown or improper operation of the dampers. Incomplete closing of the damper, which opens the air supply channel from the outside, will reduce the overall heating efficiency.
3. Increased noise during stove operation. The rotor bearings in the heater electric motor begin to make noise when wear appears. Also, sometimes noise pollution is caused by system clogging due to the creation of turbulent flows in the mains.
4. Complete failure of the electric motor. Frequent breakdowns. The reason is often complete exhaustion of the brushes or burnout of the stator or rotor windings. Also, wiring contact failure or malfunctions in the heater intensity regulator may manifest themselves in a similar way.

REFERENCE. Often, low airflow intensity is associated with critical clogging of the cabin filter. The filter has a limited service life. After the official warranty from the dealer expires, many car enthusiasts switch to carrying out maintenance themselves. And often the need to replace the cabin filter is simply forgotten.

It is recommended to check the performance of the stove before the onset of cold weather, so as not to be left without heating with the onset of winter, replacing the heater motor on the Nissan Qashqai in time.

Instructions for replacing the stove motor

The procedure for replacing a heating system motor is also not an easy task. But if you are used to repairing a car with your own hands, then it will not cause you any difficulties.

To replace the heater motor, follow these steps:

1. First you need to dismantle the dashboard. To do this, disconnect all the necessary fasteners and unscrew the bolts on which the control panel is attached. Disconnect the device from all connectors and plugs and set it aside. All work on the control panel must be carried out carefully to prevent damage to this unit.
2. When the instrument panel is removed, it is necessary to dismantle the steering column beam. You will need a standard plumbing tool for this.
3. Having done this, you can dismantle the heating device itself, as well as the cooling unit. When removing, also be careful not to damage these system elements.
4. After these steps, it is necessary to remove the electrical wiring retaining clip from the upper chamber of the intake flap. It should be noted that quite often problems in the operation of a particular mechanism are caused precisely by electrical circuit malfunctions. Therefore, when removing the wiring, be careful not to damage the circuit. If you see that the contacts in the plugs have begun to oxidize, then they must be cleaned immediately, this will avoid possible problems in the future. Use a construction brush to clean the contacts.
5. Next, following the diagram, you need to disconnect the connector marked with the letter B from the damper motor. Having done this, you need to unscrew the mounting bolts A from the housing of the heating unit and the cooling unit using wrenches.
6. After these steps, you can dismantle the intake flap motor, marked 1 in the diagram.
7. Then you should remove the air conditioning system motor.
8. The system venting device moves slightly to the right, after which you can remove the mounting pin along with the elbow. Having dismantled the stove motor, you need to connect a new device instead of the old one, fix and connect it. Mount the engine as securely as possible, this will prevent vibration and, accordingly, more accelerated wear and failure. After installation, further assembly is carried out in reverse order.

Motor repair

Don’t rush to throw away the old motor; perhaps you can bring it back to life. You will need to do the following:

1. There is a nut number 8 on top of the motor; it needs to be unscrewed, which will allow you to dismantle the impeller. She can sit tightly in her seat. If you apply a lot of force, the part will burst. You can warm it up with a hair dryer or treat it with a special compound.

2. A lot of dust and debris collects on the upper bushing, and dirt is deposited on the inside of the impeller. The lower motor hub will look no better. All these parts need to be cleaned until they shine.
3. We pay attention to the brushes, which are often worn out. We make replacements if necessary.

4. We dismantle the washers, carefully bend the petals and take out the bushing, which also needs cleaning.
5. We check the operation of the bearing, during which there should be no extraneous noise or hum. Otherwise, we replace it with a similar one. To replace the bearing, you need to bend the petals further and remove the faulty part.

6. All that remains is to assemble the motor and install it in its original place in the car. All steps are performed in reverse order. We check the operation of the stove, how the fan works, whether the intensity of airflow in the cabin changes due to temperature changes, how quietly the stove operates.

Of course, all this work can be entrusted to specialists. On the other hand, it is not so complicated that you would deny yourself the pleasure of tinkering with your favorite machine.

Problems with the Nissan interior air conditioning and heating system and their solution

The most frequently used component in any vehicle during cold weather is the heater. Without this device, driving a car will be less comfortable, so before the start of winter, the car owner is simply obliged to diagnose the health of the heater. If the system does not work, it can be caused by various problems, but the motor is usually the cause. In this article we will talk about how to replace the heater motor in a Nissan Qashqai or any other model.

Stove fan diagram

To get to the unit we are interested in, we need to remove the pedal block and begin disassembling the heater housing from the cabin filter side. This procedure is quite labor-intensive and requires certain skills. Therefore, it is better to trust those people who have experience in such things.

Brief introduction to the car

This is a compact crossover from a Japanese company. The car was produced in Japan from 2007 to 2014. The car was sold in its homeland, as well as in Australia.

The most interesting thing here is that Nissan Dualis is just another name for a crossover that almost every domestic car enthusiast is familiar with. The thing is that the name Dualis was used only for Japan and Australia. In all other countries, the crossover was sold under the name Qashqai. That is, in front of you is simply a first-generation Qashqai.

The car was offered with gasoline and diesel engines, with all-wheel drive and front-wheel drive. The gearbox could be either manual or CVT. As with the Qashqai, the Dualis was also offered in an extended body with 3 rows of seats.

In 2010, Qashqai underwent a planned restyling. The same thing happened with Dualis in Australia. Although in Japan they ultimately decided not to change the appearance. Production ended in 2014.

The heater on the Qashqai does not work: reasons

A small but quite cozy crossover from Nissan has gained considerable popularity in Russia, and this is justified. Compact in appearance, the car has considerable spaciousness, allowing you to fit comfortably into the cabin. An additional advantage can be considered low fuel consumption - in this Qashqai can be compared to a hatchback.

The first generation Nissan Qashqai J10 has been produced since 2006. In 2010, a restyling was carried out, after which the interior was significantly changed, several new engine and gearbox options were added.

Low fuel consumption is beneficial and pleasant, if you do not take into account the impact of such savings on interior heating. In the 2008 Nissan Qashqai, coolant takes heat from the engine and uses it to heat the air, which is sent inside the car. But if the engine operates with a certain fuel starvation, then its operating temperature is low, and therefore it is not able to fully warm up the car.

Owners of the first generation Nissan Qashqai faced exactly this problem. In addition to the fact that customer reviews indicate frequent breakdowns of the heater motor, even without any defects it barely warmed up the interior.

After restyling, the situation changed for the better. Even though the parts of the heating system have not become better or more durable, the interior of the Qashqai has become warmer and more comfortable.

The second generation of the 2014 Nissan Qashqai J11 (restyling in 2017) came out with major changes and no longer has such problems. The heating system has been redesigned, so now the owners of this car do not have to freeze. By warming up a new car (no older than 2012) for 10-15 minutes, you can create quite comfortable conditions in the cabin, even if there is a specific minus outside.

Diagnostics

In Nissan Qashqai, as in other cars with a liquid-cooled engine, the heater uses engine heat for heating. Therefore, the point of diagnostics is to understand at what section of the heating system (which is associated with engine cooling) the operation becomes incorrect.

1. Check the coolant level. When the tank is filled below the minimum level, there is a high probability of an air lock forming in the heater core, which is why part of the radiator will be constantly cold and the air passing through it will not warm up sufficiently.
2. Make sure the thermostat is working correctly. This can be done either using a pyrometer or by touch. The degree of heating of the surface (unheated engine) before the thermostat should be significantly higher than after it. These values ​​should equalize after 80° C. If the temperature readings are the same throughout the entire operation of the motor, it means that the thermostat is not working correctly and must be replaced.
3. Check the capacity of the cabin filter. Due to the fact that “outboard” air is used to heat the interior, which contains a large amount of impurities (dust, dirt, etc.), it needs to be cleaned. For cleaning, a filter element is used, which is capable of passing only air through itself, and all impurities remain on the ribbed structure. Like the engine air filter, it needs to be replaced when performance deteriorates.
4. Make sure there is good flow of coolant and air through the heater core. From the outside, the radiator can become clogged with dust and prevent the free flow of flow through the honeycombs. A rust plug may form in the internal part, which will block the free passage of liquid through the radiator, which will negatively affect the heat transfer of the interior heating system. To check for blockage, you need to touch the temperature of the pipes at the entrance to the stove and at the exit from it. They should be approximately the same. If the inlet pipe is warm and the outlet pipe is cool, then the plug is inside the radiator. In this case, it is necessary to clean or replace it, since for good heating of the interior, unhindered circulation of liquid through all elements is necessary.
5. A broken heater fan can cause poor heating, since the interior is heated by forcing cold air through a hot radiator. The fan is responsible for “pumping” air. It may not work at all or work incorrectly. If there are no signs of “life” in the electric motor, it is necessary to check the serviceability of the fuse. If it burns out, it is necessary to eliminate the short circuit (it can be in the wiring or in the electric motor). The impeller may also be faulty. It is made of plastic, which itself is a very fragile material, and over time can be destroyed by rotation. When the impeller is destroyed, air circulation deteriorates and heating becomes insufficient.
6. A poorly functioning or jammed pump significantly impairs the circulation of fluid through the system, which, in turn, leads to unsatisfactory heating. This breakdown threatens the failure of the entire motor, since heat is not removed from highly heated parts, causing them to overheat. This type of breakdown can only be diagnosed in the early stages. For diagnosis you need:

• switch the heater control to manual mode and set the maximum temperature;
• turn on the fan at medium speed and place your palm near any deflector;
• When increasing engine speed, monitor the increase in flow temperature; if the increase is significant, then the pump is faulty.

Repair

After identifying the cause of the malfunction, you can begin to eliminate the breakdown. Elimination may involve repairing failed equipment or replacing it with new one. You need to act based on the nature and extent of the damage.

1. If there is insufficient coolant, you need to find the leak and fix it. Then add coolant to normal and remove the air lock. You can remove the air lock by pushing through the rubber pipes with the engine running.
2. A non-working thermostat must be replaced with a new one, while draining the coolant. This type of repair is not complicated and, if you have a new thermostat, will not require much time. You just need to drain the coolant, unscrew the thermostat cover and replace it with a new one. Next, fill in coolant and bleed the system as described in point No. 1.
3. A clogged cabin filter causes the windows to fog up (when the heater is on) and is accompanied by an unpleasant odor when the fan is turned on. To replace you need:
   remove the glove compartment;
4. open the lid and remove the old element;
5. Having removed the accumulated debris, install a new element.
6. For the best effect, it is necessary to clean the stove radiator both inside and outside. The honeycombs in its outer part become clogged with dust, and they cannot allow enough air to pass through them. The inside becomes clogged with debris from the engine cooling system. In addition to cleaning the radiator, you need to clean the entire system, otherwise the effect of such cleaning will not last long. For cleaning, you can use chemicals, or by forced circulation of water, wash out the accumulated debris until it is completely clean.
7. A faulty heater motor may be caused by a blown fuse or lack of power. If power comes in, it means the electric motor itself is faulty. You can try to repair it, and if the repair is unsuccessful, replace it with a new one.
8. Operating a vehicle with a non-functioning pump is prohibited. If the water pump fails, you must postpone your planned trip until the breakdown is repaired. If heat is not removed from highly heated parts, they can become deformed, which will lead to failure of the entire internal combustion engine or increase the cost of repairs tenfold. The pump has a pulley and an impeller. The pulley, through a belt drive, rotates the impeller, which, in turn, drives the coolant. The pump impeller may collapse under the influence of an aggressive environment and cease to create sufficient pressure for coolant movement, which will lead to the heater not heating the air sufficiently.
