Removing and replacing the Renault Megane 2 heater motor

The question “how to remove the Renault Megane 2 heater fan” will be answered by this photo report for car owners.

, you can get to the heater fan , to the right of the pedals. Since the place is not lit, you will need a flashlight.

There are many reasons for carrying out such a procedure. In this case, the assembly was removed due to the appearance of a strong hum , rumble when the fan was operating due to the fact that leaves got into the impeller in an unknown way, which were subsequently removed.

Which heater fan should I install on Renault Megane 2?

Original number 7701056965, average price about 12,734 rubles.

Analogues:

Temal 402765M — 2034 rub.
Valeo 698729 — 3894 rub.
ERA 664025 — 2885 rub.

First of all, carefully remove the cover. The key latch is located in the center of the panel. Just pull back.

You will see the following picture. Having grabbed a flashlight, we make our way towards the pedals.

Remove the brake light button by turning it counterclockwise and removing it.

Remove the connector from the gas pedal by pressing on the flat side on the right along the way and remove it. You may have to pry it off with a screwdriver.

Then the brake - we pick out the lock washer, remove it from the rod and lower the lock down, remove the axle to the right along the way.

Using a 13mm wrench, unscrew the 4 nuts securing the pedal assembly and remove it.

Next we go even deeper. In the depths at the top we see the required unit. We disconnect another connector, latches at the ends.

He's very close. Everything is very simple. Proceed as indicated in the photo.

Next you will have to tinker a little. We remove the connector with two thick wires by prying the latch from below in the direction from the center of the assembly. Open the connector like a trunk lid. Then move it off the axis to the left along the way.

The most interesting part is getting the assembly out; the brake rod prevents this. If you act according to Renault regulations, then there is no problem, but the amount of work doubles. However, a way out can be found in any situation - you need to squeeze it between the heater pipes and the brake rod. It only works in one position of the motor. Reassemble in reverse order.

Despite the rapidly developing technological progress in the automotive industry, ideal spare parts have not yet been invented and any element of one of the systems can break. The Renault Megane 2 model from the famous French manufacturer Renault is not immune from such an unpleasant situation.

The operating principle of the heating system in Renault Megane 2 is identical to that found in many models from other manufacturers. If the stove motor fails, you can replace it yourself. The opinion of many car enthusiasts about the labor intensity of this procedure will be incorrect, since they believe that in order to carry out such repairs as replacing the heater motor, the front panel in the cabin should be completely disassembled. In this article we will talk about how to replace the stove motor, plus you need to know how to remove the motor correctly.

So, how to remove the motor? First, remove the cover on the panel near the pedals. We act with extreme caution to avoid damaging it. There is a key lock in the center. We just pull it back.
The second step is to move to the area where the pedals are located. To ensure better visibility, it is recommended to arm yourself with a flashlight (preferably one that is worn on the head). We find the brake light button and dismantle it. For these purposes, you need to turn the button in the reverse clockwise direction and remove the element itself.
The next step is to remove the accelerator pedal connector. Here we lightly press on the flat side and then release the latch. If it is difficult to open it with your hands, you can use a screwdriver.
Let's move on to the brake. We remove the lock washer, then the nut, and then disconnect the pedal from the rod, which we lower in the downward direction. We take out the axis itself to the right (along the way).
We dismantle the pedal assembly by first unscrewing the 4 nuts securing it.
We move our gaze further - deeper into the panel. The heater motor we need is located there. We disconnect another latch by squeezing its legs from the end sides.
After approaching the heater, press the tongue on the latch at the top of the unit and turn it back clockwise.
Next, remove the connectors with two thick cables. We disconnect the connectors using a principle similar to unlocking the trunk lid.
The final stage. We remove the heater motor from its mounting niche. This is where the difficulty arises because the brake rod is in the way. Using your imagination, you can squeeze the part between the stove tubes and the rod itself (only in one specific position). We perform this action carefully to avoid damaging the unit.
The dismantling process is complete. Installation of a new motor on a Renault Megane 2 is carried out in the exact reverse order of dismantling. This is an easy way to replace the heater motor.

What are the signs of a breakdown?

Replacing antifreeze Renault Megane 2 engine 1.6
Renault Megane 2 engine oil change
Steering column cable Renault Megane 2

Identifying motor faults is not difficult. There are several signs indicating its failure.

The fan rotation speeds fixed by the cabin regulator disappear. Not all of them may be included, but only some of them.
The rotation speed of the fan impeller decreases.
There are difficulties starting the stove (sometimes after a targeted hit on the right area of the panel).
The fan did not start, and a wiring smell arose in the interior of the Renault Megane 2.

In addition to purchasing the motor itself, the repair procedure will require a new control unit, since there are frequent cases of burnout of the connector terminals and resistor module. The price for this unit is quite high, especially if it is an original product. It would be useful to once again verify that the module has failed.

In order to avoid the majority of unpleasant moments associated with unforeseen breakdowns of any component in the Renault Megane 2 car, you should adhere to the scheduled maintenance deadlines, which will not only ensure safety and save resources, but also avoid many surprises on the road.

We move our heads towards the pedals. A breakdown can happen to the French car Renault Megane.

There we see the stove motor we need. Now we disconnect another connector. After you have opened the heater, you need to press the tab on the latch on top and turn it counterclockwise.

Now you need to remove the connectors with two wires, the thicker ones. The connector opens according to the same principle as the trunk lid.

Well, the last stage. We take out the Renault Megane stove assembly.

Step-by-step instruction

This cannot be done until you understand the brake rod. Here you will have to try and show your imagination.

The Renault Megane motor fits best under the brake pedal rod. This must be done very carefully, trying not to damage the motor itself and the elements adjacent to it.

Assembling the motor is also easy. To do this, perform all steps in reverse order.

For this, there are a number of signals that indicate this: Not all of them may disappear at once, but only some. After which, over time, they too begin to act up until they stop working altogether.

Decrease in fan speed. The interior smells like wiring, and the engine won't start at all. This is an extreme case, after detection of which it is necessary to urgently carry out repairs.

We repair the system with our own hands

Many repairs can be done independently, both on gasoline and diesel models. Having found out the reason for the poor operation of the stove, it is necessary to eliminate the malfunction.

Removing the fan on Renault Megane of all three generations is not very easy. In order to dismantle a fan with a motor that does not turn on, you must perform the following steps:

Remove the plastic cover that is located near the pedals (on the right). This must be done carefully so as not to damage the fragile plastic latches. Turn the brake light sensor counterclockwise and remove it.
Disconnect the gas pedal connector and remove the brake axle, first removing the lock washer and lowering the lock down. Using a 13mm wrench, unscrew the nuts securing the pedal assembly and dismantle it.
Inside the resulting niche we find the required part (for this you need to use a flashlight). Remove the fan assembly by disconnecting the connector.
In order to remove the fan, you need to press the lock and turn it counterclockwise. It is quite difficult to remove the part from its normal location, since the brake rod is in the way. You can carefully remove it from between the antifreeze tubes. You must act extremely carefully so as not to damage the heater impeller. Inspect the part for blockages and mechanical damage, due to which it may not turn on.

"Symptoms" of a breakdown

To replace it, you will need to purchase not only the motor itself, but also its control unit, because, as a rule, both the terminals in the connector and the resistor unit burn out. The price of the block is quite expensive, especially if you buy everything from the manufacturer. Therefore, it is better to first disassemble the panel and check exactly what needs to be changed.

No matter how the modern auto industry develops, it is still difficult to achieve ideal quality parts. They can break at any moment, since the conditions under which they are tested at the factory and in real life can sometimes be radically different. Products from the French manufacturer Renault are not immune to this kind of problem.

The heating system here is made like on most modern cars, including those from other manufacturers. If the Renault Megane 2 heater fan fails, then car owners have the opportunity to replace it themselves. Many people believe that this is a rather complicated procedure, since the part is located deep behind the control panel. In fact, by following the correct procedure, quick and easy replacement is possible.

Important points

When replacing a stove fan with a Renault Megane, you need to remember the nuances that, at first glance, seem insignificant, but are actually very important. Here they are:

as stated above, repairs begin with removing the side trim. But it is not always possible to remove it without problems, even if the central latch has successfully opened. After all, the pad sits in its niche so tightly that you simply cannot catch on it. There is only one way out: use a knife with a thin blade. The knife is carefully inserted into the slot and the cover is raised. But here you need to be careful not to break the fragile latches along the edges of the lining;

pulling out the axle on the brake rod is not an easy task: it fits very tightly, and, moreover, in some cases it also rusts, literally welding to the rod. If this is exactly what happened, WD40 liquid will help. You need to generously lubricate the rust with this composition and wait 15 minutes. Even the rustiest axle can be removed without problems;

The best option for removing rusted parts is WD40 liquid.

When going to the store for a new furnace fan for your Renault Megane, remember: it cannot be cheap. Its price starts from 4,000 rubles if purchased from official dealers. If somewhere the price is lower, there is a high probability that it is a Chinese fake. For this reason, you should buy spare parts only in Renault branded stores.

Even a novice car enthusiast can replace a faulty fan on a Renault Megane of the second or third model. Certain difficulties arise only when removing the unscrewed electric motor. But if you remove it as shown in the instructions, the impeller and motor will remain intact.

Main symptoms of malfunctions.

You can understand that a fan repair is needed based on several signs:

The fan only runs at one speed. Modes do not switch.
The fan speed decreases.
Sometimes the fan stops spontaneously.
When turned on, there is a wiring smell.

In all of the above cases, you should first check the resistor of the Renault Megane heater. If it is in good condition and power is supplied to the engine, repairs should begin.

Replacing the fan.

To repair the fan, you need to remove the entire structure, including the Renault Megane 2 heater motor. To do this, you do not need to have special skills, just follow a certain procedure:

First you need to remove the cover on the panel located in the pedal area. Do not pull too hard because there is a plastic retainer in the center that may be damaged.
After this, you should carefully inspect the space under the panel. Below it is a brake light button. To remove it, you need to turn it counterclockwise, then remove it by pulling it towards you.
To keep the accelerator pedal out of the way, you need to remove it. To do this, you need to disconnect the latch by pressing on its flat side. To make the process easier, you can help yourself with a screwdriver.
Then the brake pedal is disconnected. It is held in place by a lock washer and nut, after which the pedal is released and can be pulled out.
The pedal assembly is removed.
After this you need to move inside the panel. Here is the Renault Megane 2 heater motor, which is held in place by latches.
It is necessary to press the lock, which is located on top, and turn the structure counterclockwise.
After this, you need to disconnect the connectors suitable for the motor.
Now you can proceed to the final stage - removing the motor. The main problem may arise at this stage in the form of the brake rod, which sticks out a little from the structure. To pull out the part, pass the rod between the tubes.
After this, you can install a new part and reassemble in the reverse order.

It is important to remember that in cases where warm air stops blowing, in addition to the fan, it is worth checking the radiator of the Renault Megane stove. Sometimes it or the pipes may become clogged and the cooling system will need to be checked.

The operating principle of the Renault Megane heater is not much different from the operation of the heaters of other cars, so it is possible to replace it yourself. Most car heaters work on this principle.

How to repair a heater fan (stove) on a Renault Megane2. Great knowledge about Renault and advertising issues...

To remove the electric motor, it is necessary to stretch the assembly between the heating hoses and the brake rod as carefully as possible. One of the steps in dismantling the electric motor of the stove is removing the brake light button. The next step is removing the connector from the accelerator pedal. Movements should be directed from the center of the element.

To replace it, you will need to purchase not only the motor itself, but also its control unit, because, as a rule, both the terminals in the connector and the resistor unit burn out. Follow all the recommendations for operating your car, then the car will serve you for a long and faithful service.

By connecting the electric heater motor directly to the battery and operating it at maximum speed, you can judge the serviceability of the unit. In addition to problems with the motor itself, there may be other problems with the interior heater that reduce the efficiency of the system. There may be several reasons for this, for example, a low level of antifreeze in the cooling system, damage to the dampers, which leads to disruption of the normal air flow. Only in this case you will not have to dismantle unnecessary elements, and you will also be able to avoid unforeseen situations.

We carry out repairs in the following sequence: Efforts should not be excessive to avoid breaking the cover. The main latch is located in the center of the surface; you just need to pull it back.

The heater fan is located in the upper part of the front panel inside the structure: To do this, carefully turn it to the left and remove it. One of the steps in dismantling the electric motor of the stove is removing the brake light button. The next step is removing the connector from the accelerator pedal. To do this, we apply some effort from the flat side using a screwdriver.

Then we remove the brake pedal, for which we disconnect the lock washer, lower the clamp, and remove the axle itself. To get to it, you will need to remove another connector with latches on the ends.

The heater fan is located deep under the front panel: The fan can be released by pressing the locking tab and rotating the device counterclockwise. At this stage, special care is required.

Step-by-step instruction

We remove the connector with two thick wires, prying the latch from below. Moskvich and Renault Megane Voronezh, Russia The cold weather set in, and with it the heater motor shut down.

And if last winter it only creaked for a cold couple of minutes, then this year it began to rustle, buzz, and also require a friendly kick to the stove body or run into a pit for starting. And everything would be fine, it won’t take long to sort out the engine - but it’s painfully tedious to get to it. The need to depressurize the air conditioning system was also frightening.

The whole procedure took about 3 hours, including revision of the wiper bushings. First, remove the wiper arms. We removed it wonderfully with a three-legged puller: Now we remove the decorative cover 2 screws, the head T of the decorative cover is removed and we observe the heater itself.

Remove the cover of the resistance block, on the right in the photo. Now you need to unscrew the 2 nuts and bolt securing the heater to the body: The third stage begins with removing the gas pedal connector. To do this, press lightly on the flat side on the right and then remove it.

If you can’t pick it up with your hands, you can use a screwdriver to pick it up further. Then remove the pedal from the rod and lower the lock down. After this, you can remove the axle towards the right.

Then you need to unscrew the four nuts that hold the pedal assembly and remove it. Now let's look deeper.

There we see the stove motor we need. Now we disconnect another connector. After you have opened the heater, you need to press the tab on the latch on top and turn it counterclockwise.

Diagnostic scheme

The movement of air through the heating system is no different from any other. Outside air is supplied through the radiator. It then passes through a supercharger, or more simply put, an electric fan and is then distributed throughout the cabin through a network of hoses and tubes.

Normal operation of the motor is accompanied by a characteristic noise. If it is missing, then the fuse in the interior part is to blame. Check its functionality. It's easy to get to - just find it on the left side of the front panel. It is necessary to check not only the integrity of it itself, but also the electrical wiring around it. After all, it is responsible for the operation of the fan in different modes.

If the fuse and resistors are intact, it's time to move on to the next step. Power the system directly from the battery and turn on the stove. It works - look further for the problem. If it doesn't work, it's time to replace it. By the way, to get to the contacts of the electric fan, you need to remove the glove compartment. The plug is disconnected, and the battery itself is connected to the black and blue network wire. And the other contact is connected to the negative terminal. A working fan will start working as before.

If all else fails, the unit is removed for routine maintenance and replacement as necessary. The algorithm of actions is as follows:
