Renault Megane 2 fuses: relay block diagrams under the hood, where they are located

Fuse box Megan 2 in the cabin

The module is installed on the left side of the dashboard. To get to the unit you will need to remove the protective cover.

The photo shows a panel of cars produced from 2005 to 2008. Regardless of the modification and configuration of the car, the location of the unit remains unchanged. The only thing that may differ is the sequence of installation of the elements.

Replacement process

The design of the block under the hood on Renault Megane cars is extremely inconvenient, so the replacement process can cause some difficulties.

How to replace a fuse?

The most labor-intensive way to change fuses on a Renault Megane 2 is in the engine compartment block.

For this you will need:

TORX keys T40, T30;
regular key for 10 and 13 mm;
a screwdriver with a flat and thin blade;
spare fuses;
removal pliers, they are located under the block cover in the passenger compartment.

To directly access the fuse links, it is necessary to remove a number of elements from the machine.

For example, on a Megane with a station wagon you need to do the following:

Disconnect the terminals from the battery and remove it from the car.
Behind the battery there is a controller unit with wires. They are secured on top with a plastic casing that must be removed.
Remove the plastic battery plate secured with three T40 screws and one regular 10 mm nut.
Remove one bolt from the controller body.
Disconnect the wire connectors on the controller. To remove them, press the latch with your finger and pull the rotary lever up.
Disconnect the wiring harness by carefully disengaging it with the tip of a screwdriver.
Remove the battery pad.
The fuse box cover will be visible underneath, secured with two T30 screws. You need to unscrew them and remove the cover.
Below it are two wiring connectors. To remove the distant one, you need to move the latch up and pull the block with wires to the left. The second small connector has a latch in its design that you need to press and disengage the block.
To disconnect the first block, to do this you need to pry and pull out the lock located on the side.
Remove the mating part of the second connector block from the block body and unscrew the bolt securing it.
Then you need to press the housing latches with the tip of a screwdriver and remove the block. This may require removing the air filter housing. It is better to drag the block from the near corner and slightly press up the plastic casing around the mounting block. This procedure is quite lengthy and requires careful execution.
The removed part is the block itself with a box put on it, which serves for tight fixation. You need to release the latches located on the sides and remove this box.
Disconnect the connectors of the unit and remove it from the car.
After this, you can replace failed elements, for example, dimensions or low beam, in accordance with the diagram.

In addition, if necessary, it is necessary to replace the inserts in a small block of highly loaded circuits. This block is visible in the lower part of the body, which is not removed from the vehicle.

The entire process of replacing a fuse on a Renault Megane 2 is described in detail in a video provided by the Useful China channel.

Replacing the fuse under the hood of Renault Megane 2

When replacing fuses, it is necessary to take into account that on Megan of the first and second generations the part is simply pulled up using standard pliers. On the third generation Megane, it first moves to the side and only then is removed.

Access to electrical equipment on such machines is easier.

In order to dismantle the block you must:

Unfasten the four latches at the corners.
Remove the two red fasteners.
Remove the wiring plug.
Remove the unit and replace the necessary parts.

How to replace the block?

Blocks may need to be replaced if the seats burn out or become damaged. Such cases occur when using fuses of the wrong rating. Replacing the block in the engine compartment is carried out according to a scheme similar to replacing fuses. In the new unit it is necessary to install fuses in the same places as in the old one

It is important to check that the rating of the inserts matches the requirements of the electrical circuit for the car's fuses. Replacing the unit on Megan 3 is much more difficult, since the car has a more complex electrical circuit, so it is better to entrust the work of changing the device on this version of the car to professionals

Megane 2 fuses under the hood

To simplify the design of the block, the module is divided into three parts. The location in the engine compartment also does not change. The part should be looked for near the battery.

Since 2006, power fuses on cars have been mounted on the positive terminal of the battery.

Here pass the power cores of loaded equipment and units that ensure the operation of the installation.

The second module is installed under the battery. To get to it, you will need to remove the battery and its mounting casing.

The third structural element is mounted hidden - in the housing of the main fuse block, there is an insert with protective elements of power circuits.

How to remove the safety block

If you install an insert that does not match the one required in terms of capacity, the fuse seats may simply burn out. Then you have to replace the safety block with a new one. How it's done?

In principle, the French Megan models of the second and third series are no different in terms of replacing the fuse box. All actions are performed in the following sequence:

The first step is to lift the hood and disconnect both battery terminals. All work must be done with the power source turned off. If this is not done, the result may be disastrous.
On the right side of the engine compartment there is a fuse mounting block.
Remove the battery.

Unscrew the four screws on the battery platform.

In the corner of the platform there is one screw securing the clamp with wires. It is unscrewed and the clamp is completely released.

Using a wrench, unscrew the screw that secures the car's fuse box.

Pull the power supply out a little and disconnect all the connectors with wires.

You get a block like this with security elements.

Now nothing prevents the free replacement of fuses on the block. The procedure for removing old fusible elements onto new ones is carried out using tweezers. After replacing the devices, the power supply unit is assembled and installed by performing the operations in the reverse order.

The Renault Megane III fuse box performs a very important function - it is responsible for the correct operation of the vehicle's electronic system. Therefore, any driver should know the location and purpose of each fuse in order to promptly eliminate malfunctions that arise during vehicle operation.

Fuse diagram

The photo above shows a diagram of the installation of interior block inserts.
This arrangement is relevant for most cars that have undergone restyling in 2008-2009. The designation is also suitable for individual vehicles from 2004. The following shows the electrical circuit of the main unit under the hood of the car.

For ease of understanding, a complete description of the module fuses is given in the subparagraphs below.

Where is the air conditioner fuse located?

The air conditioning system for diesel and gasoline cars does not differ in design. Several fusible elements are responsible for the operation of a complex block simultaneously.

The unit control activation line passes through 1 slot of the motor module. The compressor clutch is powered from fuse 16 located nearby. The controls are protected by insert 10, mounted in the cabin, and the drive power line operates from element 19 under the instrument panel.

Gasoline pump

The fuel pump is powered in a special way. There are no fuses in the line; their role is performed by the engine ECU. If the power supply to the installation is lost, this is where you should look for the cause.

Cigarette lighter fuse

On classic versions, if only the socket does not work, the reason should be sought from element 7 in the car interior. Some motorists install an additional unit with a direct line from the battery.

Starter

The control line fuse stands out from the general range of devices.
You should look for it under the hood near the battery. It should be taken into account that the part in most configurations differs in the installation location. Some modifications do not have such an element at all - there is only a relay powered through the ignition switch. If the insert constantly burns out, the cause should be sought in the starter.

Heater fuse: where is it located?

In versions without an air conditioning system, the heater motor protection is installed under the dashboard at position 19.

Fan

Information on blowing the heater is indicated above. For the radiator cooler, power is supplied from power element 18 in the engine area of the car. The insert is responsible for both drive rotation speeds (if any).

Wipers

The front wiper power line operates from insert 22. The breaker relay is usually mounted near the drive.

Where is the low beam fuse located?

It's not that simple with lamps. There is a triple highway here. Fuse 4 supplies power to the right block, inserts 5 and 7 are responsible for the left side of the machine.

This arrangement is relevant due to the increased complexity of the design of optical elements.

Positive terminal fuse

This is a higher value insert. The part is usually mounted on the terminal itself under number 1. In some versions of the car, the installation location of the element may differ slightly.

Battery fuses

Mounted in the same place in the second position. Likewise, the installation area may vary between different vehicle generations and trim levels.

Window lifter

The button system is powered via one line. The line is served by fuse 7 of the cabin unit. A little lower, at number 20, the power element of the motors is mounted - number 20.

Reverse fuse

The lamps are protected by insert 14 of the interior block. Motorists transfer the element from the mounting panel under the dashboard. This is usually due to serious electrical problems and subsequent low-quality repairs.

Dimensions

The port side lights are powered from cabin fuse No. 1. The lighting on the right side is served by insert 7.

ABS fuse

The device control controller is powered from No. 19. The performance of ABS drives and sensors depends on element 5, mounted in the power unit at the battery terminal.

Trunk lock fuse

On the sedan version, insert 6, installed under the dashboard on the driver's side, is responsible for locking the cargo compartment lid.

Megan 2: windshield washer fuse

The Lobovukht windshield washer is a simple device. Element 10 installed in the tidy module is responsible for powering the motor.

Stop signal

Dashboard

Indication and operation are controlled by fuse 15 installed in the motor part.

Fog lights

If the car has a PTF, fuse 6 is installed under the hood in the main block. The fog lights are powered for the right and left sides of the car on the same line.

Turn signals

The turn signal and hazard warning system is part of the vehicle's comfort module. In some configurations, fuses are mounted under the instrument panel on empty sockets.

Climate control

The climate control system is similarly controlled by the comfort unit. In the first modifications, fuses were installed in places reserved for the air conditioner.

Automatic transmission selector

The machine position indicator is powered from insert 10 in the vehicle interior. The selector electronics operates from element 12.

Radio tape recorder

The standard sound system is connected to fuse 10 of the cabin module. Some car enthusiasts, when installing a modified radio and speakers, run separate lines from the battery. The position of the insert is correct only in the case of a factory player.

Heater

The fuses for the interior heating system are described above.

Mirror fuse

The exterior mirror heater system is made on one wiring branch for both sides of the car. Insert 8 in the cabin is responsible for the operation of the tennov.

Similar design on ZVV adjustment drives. The servos are powered through fuse 15, mounted under the instrument panel.

Number plate illumination

The sign lighting is connected to the general system of side lights. If the device does not work, the reason should be sought in the specified circuit.

Electrical and electronics

It may fail due to burnt terminals and loss of contact. Don't believe me? Try cleaning the terminals and then starting the vehicle again.

In the morning I went to work, started to start it, and she was acting up again, immo didn’t see the key again. I tried removing the chip from the hazard warning button and, lo and behold, everything worked.

Today I decided to see what it was.

Why won't Renault Megane 2 start? Troubleshooting and troubleshooting

I removed the fuse box from under the panel. And I saw wet marks on it, took it apart and saw a sad picture, mold was growing on the board. You need to give it to a specialist to clean everything and solder what needs to be done.

Relay Megan 2

If fuses primarily protect low-power machine equipment, relay switches are installed to supply voltage to energy-intensive consumers and devices.

Air conditioner relay

Installed in the engine compartment separately from the entire unit. You should look for the element on the interior bulkhead.

Fuel pump

The switch is located near the unit. On Scenic diesel engines, there is also a heated filter. The part is mounted at position 7 under the hood of the car.

Starter relay

The switch is located on the right wing of the car. In some configurations, the device is installed in block number 4. The pull-in relay for the company’s conveyor is supplied by Valeo. The unit is standardly mounted in the launcher body.

Cooling fan relay

Forced engine cooling systems, mounted near the radiator or on the left fender of the car.

Wiper relay

The windshield wiper control system is built on two independent lines. The wiper motor relay is installed under the instrument panel or in the engine compartment on the battery side.

Low beam relay

Installed on the head optics from the rear side

Power window relay

The power supply to the power windows is located under the instrument panel at position 1. The glass position regulators are installed in the control unit under the car trim.

Wiper

The wiper relay is mounted under the dashboard on the driver's side. It can be found by the characteristic clicks when activated.

Generator regulator

The switch for supplying voltage from the generator set is installed on the fender of the vehicle in front of the battery.

Glow plug relay

They are activated thanks to relays No. 1 and 3 installed under the battery.

Megan 2 - main relay: where is it located

The ECU is mounted near the interior air vent on a metal bulkhead.

Charging relay

Controlled by a special relay. The device is installed near the generator on the line leading to the battery.

Paid links

Extraction should be done with tweezers specially designed for this purpose, which are located there. First of all, make sure that the fuses really need to be replaced.

Fuse and relay block VAZ 2107

They are grouped around the steering wheel to release the Renault Fluence dashboard. The systems are controlled almost intuitively. There are no complaints about the quality of materials and the size of the joints; it is minimal. A driver of any height and build can find a comfortable driving position.

And all thanks to the many settings of both the seat and steering wheel. It is possible to adjust the inclination of the seat back and headrest, change the lumbar support adjustment, adjust the steering wheel in height and reach, adjust the position of the seat, which can move in height by 70 mm, rise and fall by 35 mm and by mm in the longitudinal direction.

Particular attention was paid to the comfort of second-row passengers. Rear seat passengers have the largest amount of knee room mm when compared to cars in the same class

An important indicator is the volume of the luggage compartment. In this regard, the model is also pleasing: Access to it is facilitated by a low loading threshold mm and a wide horizontal opening mm due to the placement of part of the rear light signals on the trunk lid.

There is a rare property for the rear seats of sedans: The gearbox is either a five- or six-speed manual, or a CVT. The Renault Fluence has a McPherson type suspension at the front.

The rear suspension is a simple and reliable solution - a torsion beam. Thanks to optimal settings for the stiffness of the suspension elements and balance, the car demonstrates very good comfort indicators.

For braking, such a dynamic car was equipped with ventilated front brake discs with a diameter of mm and conventional rear brake discs with a diameter of mm.

Firmware for Renault Fluence

Paying a lot of attention to detail, the designers made Fluence a class leader. So, the car can be equipped with: And a climate control system with air supply to the rear seats is generally included as standard.
