Replacing the Qashqai stove motor

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 malfunctions

If the heater fan does not work in a Nissan Tiida, Qashqai, Beetle or any other car, then this problem needs to be solved as quickly as possible. After all, constant inoperability can lead to the fact that if the windows fog up, which happens quite often in winter, they will remain fogged up. Moreover, if it is frosty outside, the windows may also freeze, and the air temperature in the cabin will be generally low. We suggest you understand the main symptoms and causes of stove malfunctions.

Signs and causes

The three main symptoms of heater failure are:

the system does not work, does not heat the air;
The speed of the heater fan does not change, despite the adjustment;
during operation, the heating system began to make sounds that were uncharacteristic of its operation, we are talking about creaks, whistles, squeals, etc.

If the motor only works at 4th speed, then the rotation speed resistor has burned out. As a rule, it is located next to the motor.

As practice shows, the main causes of such symptoms are as follows:

If the heater does not work at all, this may be due to wear of brushes or lamellas, as well as burnout of the winding. In this case, you will need to replace the system's electric motor. If the problem lies in a burnt-out transistor, then it will also need to be replaced. In some cases, the reason lies in a failed thermal fuse, which is located in the resistor block, then you only have to change this element.
If the fan does not change the rotation speed when adjusting this parameter from the passenger compartment, then most likely the problem lies in the transistor; this component will need to be replaced.
The appearance of extraneous sounds, as a rule, indicates wear of the bushing. If this is the case, then you will need to change the heater motor. You can read reviews online about replacing bushings with bearings - we do not recommend doing this, since the replacement procedure as a whole is a painstaking task, and it is not a fact that the result will suit you (the author of the video is the channel Valery Deryugin).

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:

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.
When the instrument panel is removed, it is necessary to dismantle the steering column beam. You will need a standard plumbing tool for this.
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.
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.
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.
After these steps, you can dismantle the intake flap motor, marked 1 in the diagram.
Then you should remove the air conditioning system motor.
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.

We change or repair the Qashqai stove fan with our own hands

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.

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:

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.
The absence of changes in the rotation speed of the motor indicates a faulty transistor.
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.

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.

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.
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.
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.
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.

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.

What kind of motor can be installed on the Nissan Qashqai stove?

For a novice driver, the issue of purchasing new parts can cause many difficulties. To prevent this from happening, we have prepared a small guide that will allow you to buy the necessary part to replace the faulty one. Motor prices in retail automobile stores are in the range of 3-4 thousand rubles. If you take a used part, you can save up to half of this amount, but no one will guarantee long-term operation. Here everyone makes a choice at their own peril and risk. The heater motor is sold together with the impeller and housing. By the way, if you haven’t found a part for your car, you can buy a motor for the X-Trail stove, since they are identical. If you replace the transistor, you can choose from several options. First of all, you need to look for IRFP064N (55V and 98A) and IRFP064NPFB (55V and 98A). The second option is a modification. If these parts are not available, then you can buy IRFP044 (60V, 57A), IRFP054 (60V, 70A) and IRFP048 (60V, 70A). But you shouldn’t even look at the IRFP250N (200V, 30A), since this transistor can burn out within a day. The transistor will cost from 100 to 200 rubles.

Removing the heating system motor

It doesn’t matter whether the heater motor is replaced or repaired, in any case it will be necessary to dismantle this mechanism. The faulty part must be removed as follows:

remove the minus from the battery;
We dismantle the left panel of the console and remove the bottom panel, which is located under the steering wheel;
disconnect the connectors from the left button block and unscrew the T20 Torx from the climate sensor;
lie on your back to unscrew the two bolts that hold the pedal assembly;
We dismantle the bracket, which will allow us to remove the pin;
disconnect the connectors from the brake pedal and accelerator sensor, which will allow you to dismantle the pedal assembly;
Now you can remove the cabin filter by first removing the cover, which is held in place by latches;
armed with a flashlight, we get closer to the stove motor;
disconnect the power, feel for the latch, squeeze it and turn the mechanism against the movement of the clock hand.

The heating system engine has been removed; then a new mechanism can be installed or the old one can be repaired.

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:

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.
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.
We pay attention to the brushes, which are often worn out. We make replacements if necessary.
We dismantle the washers, carefully bend the petals and take out the bushing, which also needs cleaning.
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.
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.

Main malfunctions and their causes

There are three main problems on the Nissan Qashqai that cause the heater to not work properly (it doesn’t heat or blow):

The heater motor stopped blowing. The problem may lie in the fact that a transistor or fuse has burned out, and, therefore, in order to correct the situation, the broken element must be replaced. Also, the cause of such a breakdown can be worn out lamellas, brushes or burnt out windings.
When the stove is running, the rotation speed (rpm) does not change, even when the knob for this parameter is turned. Most likely, this indicates that the transistor has burned out, and in order to correct the situation, it must be replaced.
Replacing the stove motor may be necessary if there are extraneous sounds during its operation. Most likely, this indicates wear of the bushings, which are quite problematic to change locally with your own hands.

Typically, the heater motor for Nissan Qashqai 2009 and other years of production is equipped with a housing and an impeller and is supplied assembled.

Repair

In most cases, if the heating and air conditioning system is not functioning well, it may be necessary to replace the heater fan or some resistor (they are located in the additional unit); in some cases, it may be necessary to replace the radiator of the heating system.

Very often there are situations when the stove heats up, but the fan does not work; in this case, you should pay attention to the serviceability of the fuse, which can be found in the cabin unit (number five).

Remove the non-functioning element, and before installing a new one, be sure to check the serviceability of the circuit. Usually after this the fan works again.

How to remove the heater motor, repair or replace it, can be seen in numerous videos presented on the Internet, each of them was filmed by a person who personally carried out the repair work.

In order to replace the motor, you must follow the following sequence:

The first step is to remove the instrument panel, as well as the steering column beam.
The cooling unit and heater should be set.
Remove the electrical wiring fastening from the intake flap (its upper chamber).
Disconnect the connector from the engine.
Remove the mounting screws from the heater housing and cooling unit.
Remove the air conditioner motor.

After this, move the fan to the right side and remove the mounting pin and elbow. Then, if necessary, you can replace the motor or other components of the heating system.
