A timely replacement of the Renault Logan 1 ball joint will help the driver avoid serious difficulties. Besides, doing it yourself is not so difficult. This article will examine not only the process of changing the Renault Logan ball joint, but also the general symptoms of a malfunction.
Replacing the stove fan
If it happens that the Renault Megane 2 stove stops working, troubleshooting did not lead to the desired result, you will have to replace it. Let's figure out how to proceed to remove the old fan:
- Open the panel, start disconnecting the pedal.

- Disconnect the brake sensors, then the gas pedal.
- To release the brake pedal lock, to do this you need to remove the locking ring, pull the lock and push out the rod. Then squeeze the end and turn it in your direction.
- Unscrew four nuts, one is hidden under the seal.
- After this, the pedal assembly is removed.
- The next step is to unscrew the high-speed control module of the Megan 2 fan, remove it, and move the wires to the side.
- It is necessary to disconnect the connector: press the latch, tilt the connector to the right and remove it upwards.
- Press the latch and turn the motor counterclockwise.
- The fan must be pulled out and turned forward with the impeller - this is the only difficult part of replacement.
- You need to pull towards yourself so that the brake rod is inside the impeller. This removes the Megane II fan.
After the completed manipulations, the new part is installed in the reverse order with careful movements, trying not to damage the impeller.
Signs of wear
Original part: 401-604-793-R RENAULT
- As usual, there is no sudden break. And if it happens, then the defective part is to blame. More often, the behavior of the suspension will indicate to the driver that the Logan ball is broken.
- The main symptom can be considered the noise that appears when driving on an uneven road, even at a low speed. It usually makes noise under the front wheels, and its main cause is either wear of a part or a lack of lubricant under the Logana support pad.
- To be fair, a knocking sound from the front suspension of the 1st generation Renault Logan may not always indicate exactly this problem. If the noise starts in the cold and everything disappears soon after the start of the trip, there is nothing to fear - most likely, the lubricant has simply frozen. And after it warmed up, everything returned to normal.
- A malfunction of the ball joint (BJ) can cause the Renault Logan to begin to behave unstably on the road. The reason lies in the play that has formed in this support. As a result, the wheel becomes loose and the car begins to wobble. If such a sign is noticed, prompt diagnosis of SHO is required.
- There are a few more signs of wear, but at the same time they may indicate other problems with the Renault Logan suspension. For example, this is a squeak when turning the steering wheel or uneven tire wear.

Repair
It's worth trying to repair the stove fan. Replacing the brushes may be enough to once again enjoy cool air in the Megan 2's cabin.
It is necessary to remove the wiring block on the motor.

Using a thin screwdriver, pry up the three latches and release the heater motor.
The brushes cannot be removed because the ends of the wires are soldered to the stator contacts. It is likely that the brushes have become worn down and have an uneven cut.
There is a need to clean contacts and intercontact gaps from dust and dirt. You can find copper-graphite brushes in hardware stores.
Having trimmed and given the required shape, solder it to the Renault Megane 2 fan. Then install the fan in place.

Step-by-step dismantling of the stove
Be careful when removing the oven fan on Renault Megane 2. So all work will go very quickly and without problems.
- Carefully remove the cover without using excessive force. The latch is located exactly in the center of the dashboard.
- An interesting landscape will open before you. Take your headlamp and move towards the pedals.
- Now eliminating the brake light control button. To do this, you need to turn it counterclockwise, then remove it.
- Next up is the accelerator pedal connector. To do this, press on the flat side. A screwdriver can be used as a lever. When you're done with the gas, move on to the brake. It is held in place by a lock washer. The connector must be removed from the rod and the latch released. As you go, pull the board to the right.
- The image below shows the mounting points for the pedal board. To remove them, use key 13.
- After all these actions you will see a cherry, or rather a fan. To access it you need to disconnect another connector. The latches are visible from the end sides. At this stage, you want to drop everything and go to a car service. How far can you go in a hot car, I wonder? Next, we continue to disassemble the stove fan.
- The knot must be turned counterclockwise.
- Now you need to remove the connector from which two thick wires pass. Pay attention to its location. The procedure can be confusing. Since we are in contact with the electrician, any faulty movement will make the car's operation dangerous. Removing the connector must begin from the center of the assembly, carefully moving it to the left along the axis.
- Next you need to start the engine between the brake rod and the radiator hoses. This is not easy to do, but it is possible. It is important to manually turn the Renault Megan 2 heater fan to the position shown in the image above. And even with great difficulty, but such a procedure will bring success.
Removing and washing the heater radiator
Before replacing the radiator, you should try flushing it. The removal process may depend on the type of Megane 2 radiator. In the case of model 7701208323 , a complete disassembly of the panel will be required, with model N80506052FI everything is much simpler.

Before removing the radiator, it is necessary to drain the antifreeze. At this time, remove the casing, disconnect the piece of iron fastened with 4 bolts and 1 self-tapping screw. This opened up access to the heater radiator and damper servomotor. Next you need to remove 2 latches, pull out the tubes, and take out the radiator. When collecting, use the reverse order.
You will see how the tubes fit to the radiator. (Link to photo source)
Removed trim
Washing can be done with strong water pressure towards the supply side. For better cleaning of the Renault Megane 2 radiator, you can fill it with a special product, for example, “Sanox”, then rinse it again with water from Karcher. All that remains is to install the removed elements in their places.
"Symptoms" of a breakdown
First of all, let’s identify all the main signs that could signal that the engine is already faulty.
- The fan starts to rotate very slowly.
- The speeds begin to gradually disappear. Most often, not all of them disappear at once, but some of them disappear separately. Then they fail—they don't work at all.
- There is a wiring smell inside the car.
- Starting up the furnace is fraught with significant difficulties. Consequently, motorists operate it only after they “hit” the lower right dashboard.
- Eventually the engine stops starting altogether. This is the most extreme case. If this malfunction is detected, begin repairs immediately.
To find out for sure that the Renault Megane 2 heater fan is not working, you need to learn a little more about car fan diagnostics.
Replacing the resistor
Problems with the operation of the Renault Megane 2 fan are not always associated with the fan itself. The malfunction may be related to the Megan 2 heater resistor.
The stores offer analogues of the original from Valeo, for example - NTY ERDCT001 .

They look the same, the new resistor worked great. You should try cleaning the old resistor with alcohol and resoldering the soldering joints. It can still serve as Megan 2.
