Description of the sound signal
The location of the button for sounding the horn in Renault Logan is not usual. It is located at the end of the low and high beam switch. This location often baffles novice owners of such cars, but if you get used to it, it is no worse than any other.
Reviews from car owners indicate that after a certain period of operation, this element often fails and the horn disappears. This is quite dangerous, because you may need it urgently on the road.
Signs and causes of malfunctions
The most common causes of malfunctions of this Renault Logan element include the following:
- plus wire break due to frequent twisting when turning on the low beam;
- blown fuse responsible for this unit.
Both of these problems can be solved with your own hands without any problems. You can understand that you have problems with this button by the operation of the beep itself.
It happens that it does not disappear completely, but sometimes it works, sometimes it doesn’t. This usually happens because at a certain position the broken wire begins to conduct the signal again. There are also malfunctions with the horn system itself, but they occur much less frequently.
In any case, if you notice problems with the operation of this part, you should fix them as quickly as possible. The sound signal constantly helps the driver to prevent accidents and other dangerous situations.
The video below is dedicated to the repair of the left steering column lever, on which the horn activation button is located (author - Aloshka ya).
Troubleshooting signal problems yourself
Repairing a signal on Renault Logan if the wire is damaged is quite simple, in a few steps:
- disconnect the battery from your car's electrical network;
- remove the plastic casing by unscrewing two screws to gain access to the switch;
- then remove the lever with the platform, they are also on two screws;
- the place where the disconnected wire is soldered should be clearly visible, but to be sure, look at the car’s electrical diagram;
- after degreasing the wire and contact, solder the end of the wire;
- place the wire so that it does not bend during assembly of the device;
- install everything in the reverse order, taking into account the connection diagram of this node.
After you complete the work, you can check the operation of the horn. This circuit will help you solve the most common beep problem.
Video “The sound signal on Logan has disappeared”
In this video you will learn how to disassemble the regulator responsible for activating the horn and how to fix the main problems (the author of the video is the Renault Repair channel).
One of the important elements that ensures safety on the road is a working horn button. A timely sound from the horn will help avoid an accident or warn a pedestrian that a car is approaching. On budget cars, this element does not have increased functionality, and situations are not uncommon when the sound signal does not work at the most inopportune moment. You can fix it yourself if you know the cause of the malfunction, its location and repair rules.
On the Renault Logan, the manufacturer decided to place the horn button in an unusual place for a car of this class - it is located on the left steering column switch, where the high and low beams are turned on. This location is typical for all generations of cars (2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017), both phase 1 and phase 2, as well as types of installed engines (1.4 or 1.6 l).
Causes of malfunctions
There may be four main factors that cause the sound signal to disappear:
- The fuse that is responsible for the operation of the device (F17) has blown, as well as additional fuses (F01, F02), which are included in the alarm wiring diagram. To check their integrity, remove the mounting block shield on the left;
- Broken wires that constantly get twisted when the low beam headlights are turned on;
- Horn malfunction;
- Switch malfunction.
In some situations, a non-working element can be repaired, but when this is not possible, it has to be replaced.
Remedies and replacement options
On the Internet you can find many videos and photos on how to disassemble and repair an audio signal yourself. Depending on the type of fault, the repair plan will depend.
Broken wires
Before carrying out work, remove power from the battery. Then unscrew the two hexagons and remove the protective cover from the steering wheel. Then the lever platform is removed. The integrity of the wire, the quality of soldering, the presence of kinks or sealed wires are inspected. If the wire has these defects, it should be replaced. Assembly is carried out in reverse order. Then you should install the battery power terminal in place and check the functionality of the horn.
Horn malfunction
This element (compressor type) is located under the hood on the left side. The sound may disappear due to its breakdown.
To repair or replace it:
- Disconnect the car and remove the “-” terminal from the battery;
- Remove the lower section of the mudguard (when replacing, the bumper is removed);
- Disconnect the block with wires;
- Unscrew the nut securing the bracket;
- Remove the signal assembly with the bracket;
- When repairing, clean the relay, and when replacing, install a new element.
Assembly is performed in reverse order.
As a replacement, instead of the Logan horn, a Volgov signal can be installed on the car.
Many Logan owners do the modification by installing 2 horns on both sides of the car. Sequencing:
- The front bumper is removed;
- The horn is located on the right side of the car;
- The bolt securing the standard horn is unscrewed;
- The installation leg is used for the Volgov horn;
- To ensure communication of the second horn, it is necessary to use a connection diagram;
After installation, the bumper is put into place and the functionality is checked.
Switch fault
The reason why the signal disappeared may be a malfunction of the switch itself. In such a situation, you will have to install a new element. To make it more convenient to work, you should open the driver's door. The installation procedure is as follows:
- The steering column covers (rear and front) are removed by touching the fastening screws and unscrewing them. To do this, the ignition key must be pulled out;
- Then the connectors of the switch are pulled out and it is unscrewed;
- Install a new single-contact switch in reverse order.
After installation, you should start the car and turn on the ignition coil, and also check how the new switch will operate.
Attention! If it is necessary to replace the horn and steering column switch, the manufacturer recommends purchasing it according to the catalog number, which indicates the spare part article. Depending on the year of manufacture, it may differ in size and price.
Timely repair or replacement of sound signal elements will ensure the safety of not only the driver, but also pedestrians on the road. Therefore, they should be performed immediately after problems are discovered.
In many ways, it is the heating and ventilation systems of the interior that create comfortable conditions in the car: they not only provide optimal temperature and air circulation, but also remove moisture and frost. Therefore, a breakdown of the stove has a detrimental effect on the condition of the car, in particular its interior: the seats can become damp, the upholstery can swell, etc.
The device of the Renault Logan car heater
The heater is located under the dashboard in the central part. The main components of the heater are a fan, distribution flaps and a radiator.
The main components of the Renault Logan heater: 5 - distribution block; 6 - heater radiator; 7 - heater pipelines; 8 - fan resistor; 9 - front left air duct for heating the footwell; 10 - air recirculation control cable; 11 - air distribution control cable; 12 - air temperature control cable
Heater radiator
The central unit of the heating system is the heat exchanger of the heater (stove), or radiator. The main function of the radiator is to heat the air entering the cabin.
The heater radiator is responsible for heating the air entering the cabin
Heater fan
Air is actively supplied to the heater while driving through special holes in the front panel lining. When more intense air supply is needed, the fan comes into play. The faster it rotates, the more air flows to the heating systems.
The fan provides more air to the heater
In physics, a resistor is understood as a passive element of an electrical circuit that can perform different functions: convert current into voltage and vice versa, limit current, absorb electrical energy, etc.
As part of the stove, the resistor is responsible for the operation of the fan, namely: it regulates the rotation speed of its blades. A resistor is connected to the motor and distributes the current, typically providing four fan speeds.
The resistor allows you to adjust the speed of the heater fan
Why does a resistor fail?
The cause of resistor failure is burnout. The fact is that it is constantly energized and transmits current. Experienced craftsmen, however, claim that the failure of the resistor may be associated with malfunctions or contamination of the fan as a whole.
When the resistor fails, all the electric current goes directly to the fan, and it only operates at the fourth, maximum speed. Therefore, diagnosing this breakdown will not be difficult for a car enthusiast.
How does the Renault Logan stove work?
Air enters the car interior - both naturally and with the help of a fan. Air coming from outside can pass through the radiator, thereby heating up, or past it. This depends on the position of the damper, which is connected to the temperature controller.
The radiator heats the air entering the cabin. This occurs due to the circulation, oddly enough, of coolant. It removes heat from the running engine, heats up and, in a heated state, flows through special pipes to the radiator. The maximum heating temperature can be up to 100 degrees - the system is closed and under pressure, which allows it to withstand such loads.
Heated air enters the cabin through deflectors - special openings located in the center and sides of the instrument panel. The air supply intensity is regulated using the heater control unit.
Possible causes of Renault Logan stove failure
Owners of Renault Logan cars often encounter the following problems: the heater does not heat up or cold air comes out of the deflators, although the pipes (the same ones through which the coolant, heated by the engine, goes to the heater radiator) are hot. There may be several explanations for this phenomenon:
- an air plug has accumulated in the pipe;
- Cabin filters or radiator cap are clogged;
- fuses have become unusable;
- low-quality/used antifreeze or insufficient coolant level;
- the antifreeze expansion tank has become unusable (usually after 100 thousand km), or its cap is loosely secured.
DIY Renault Logan stove repair
If a malfunction occurs, it is not necessary to immediately go to the service center. Many breakdowns are not as serious as they seem, and you can handle them yourself. And it is also worth noting that the entire Renault Logan stove is not replaced - it is enough to replace the failed part.
Troubleshooting minor problems
If “alarming symptoms” occur, it is necessary to consistently check the condition of the antifreeze and the vehicle components described above. If air pockets are detected in the system, they must be vented. Clogged filters and caps should be cleaned or replaced. Used antifreeze must be drained and new one added. The expansion tank can also be changed; in this case, it is better to leave the “original” lid - it will hold pressure better.
If the manipulations done do not have an effect, then the problem lies in one of the heater components.
Replacing the heater fan
A sign that the source of the malfunction is the fan (the brushes are worn out or the electric motor is out of order) is a weak air flow from the deflectors or its complete absence. In this case, the fan must be replaced.
Replacing the Renault Logan heater fan is carried out in the following order:
Changing the resistor
A sure indicator that it is the resistor that has failed is that the stove fan is only operating at speed four.
The resistor is located at the back of the fan housing. You need to look for it in the area of the pedal assembly (on the right side). This element is a white plastic rectangular “socket” to which a block with wires is attached. Replacing the Renault Logan heater resistor is carried out in the following order:
Installing a new radiator
Replacing the heater radiator on a Renault Logan is required if coolant begins to leak through it. Replacing a radiator is the most complex and time-consuming process when repairing a car heater with your own hands.
Sequence of actions when replacing the radiator:
- Drain the antifreeze completely.
- Remove the instrument cluster and console trim.
- Remove the carpet fastening to the cross member bracket and bend the carpet back.
First you need to remove the carpet
- Unscrew the bracket fastening (two bolts at the bottom and two nuts at the top).
Unscrew the bracket fastening
- Release the bracket from the wires and remove it from the beam.
The final stage - remove the mountings of the Renault Logan heater radiator
- Replace the radiator and perform all the steps in reverse order, not forgetting to first put the rubber seals on the tips of the tubes.
Replacing the heater light bulb
The main problem with a faulty light bulb is that it can signal that the stove is not working, although the heater will function normally.
To change a light bulb you need:
- Remove the radio cover and the buttons that control the operation of the stove.
- Unscrew the fasteners of the module and press in its lower part, and pull the upper part towards you.
- Find the latches on the sides and press them out.
- Unscrew the panel and look for the burnt out light bulb.
- Replace the light bulb and perform all manipulations in reverse order.
Preventing stove breakdowns
Of course, it is much easier to prevent problems from occurring than to fix them. For the stove to work without failures, you must:
- change the cabin filter regularly;
- use only high-quality antifreeze (official dealers recommend GLACEOL RX Type D 1 Renault 7711428132 from ELF) to avoid damage to the radiator and pipes;
- It is advisable to flush the entire system with water or a special liquid before the start of the season.
Using the seemingly simple methods described above, you can repair the Renault Logan stove yourself. However, it is worth taking on this business if you are completely confident in your abilities and skills. Otherwise, you may not only fail to repair the stove, but also render the entire heating and ventilation system of the car unusable.
Every year, engineers try to improve engine designs for the sake of efficiency and environmental friendliness of these units. Due to this, the number of breakdowns associated with unstable, poor engine operation, up to its complete stop, is growing. Owners have more than once encountered the problem of poor engine starting, as well as its unstable operation. Of course, if it stalls, the first thing you do is go to a service station. In this article we will talk about the most common malfunctions associated with the operation of the Renault Logan internal combustion engine, and also consider methods for eliminating them.
Most common faults
If the engine of your Logan starts poorly or stalls altogether, the following faults may be the culprits:
- The fuel pressure regulator is faulty.
- Bad spark due to failure of the high-voltage part, namely spark plugs, coils and wires.
- Incorrect installation of the gas distribution mechanism marks, resulting in asynchronous operation of the fuel combustion phases.
- The throttle valve that regulates the air flow into the engine is faulty.
- Possible problems with the immobilizer, as a rule, the control unit loses communication with the key chip.
- If the engine stalls unexpectedly while driving, you need to check the quality of the spray.
- Another reason that the engine stalls while driving may be a dirty fuel filter.
- If the engine starts poorly or starts and immediately stalls, the breakdown may be related to the fuel pump.
- If or starts poorly and after some time stalls at an unexpected moment, the culprit may be a faulty one.
- Wear of the camshaft and its sensor can cause poor starting and subsequent engine performance.
Let's look at some of the reasons for poor engine performance and try to diagnose these breakdowns on our own.
Diagnostics
- If the fuel pressure regulator is not working well, it usually needs to be replaced. To verify that it is faulty, you need to unscrew the fuel return hose and then turn on the ignition. If gasoline comes out of this hose under high pressure, the regulator will not work. To eliminate a fault in the path, it is enough to plug one end of it, or press down the return pipe, thereby reducing its cross-section. Having carried out such work, you can easily get to the repair site.
- If the spark is not supplied to the cylinders properly, interruptions in engine operation occur. To verify that this unit is faulty, you must have a special wrench on hand for unscrewing the spark plugs. Having unscrewed the spark plugs, you need to connect them to the tips of the high-voltage wires and turn the starter several times. If the spark goes to the side or its strength is not enough, this unit needs to be replaced. As a rule, a car with such a breakdown can get to the repair site on its own.
Attention! Follow safety regulations when carrying out such work. The high-voltage part of the car is very dangerous to life and health.
- If the valve timing marks are set incorrectly, the engine runs with significant interruptions with characteristic popping noises.
This malfunction cannot be eliminated without the proper equipment and tools. If this malfunction occurs to you on the road, do not try to fix it yourself. Tow the car to the nearest car service center and only carry out repairs there.
- If the damper that regulates the air flow is faulty, there are several ways to identify this breakdown and also fix it. Unscrew the air supply pipe and inspect the throttle valve for integrity.
When the engine is turned off, its position should be in the closed state. If this does not happen, this unit must be cleaned and then adapted using computer equipment. As practice shows, this malfunction appears gradually and cannot just happen on the road. Accordingly, such repairs must be done at a specialized service station.
- If it starts and after a while it immediately stalls, pay attention to the dashboard, namely, whether the immobilizer indicator lamp is illuminated. If this indicator light flashes, the immobilizer unit has lost communication with the key chip. You can continue driving only by using another spare key to replace the old one.
With the help of special equipment, the key used can be registered in the program of the immobilizer unit, but this is done on special equipment.
Tip: Carry a spare key with you if you go on a long journey.
- The operation of fuel injectors can only be checked at an equipped stand; accordingly, such repairs are carried out by specialists.
- If the fuel filter in your car is clogged, of course, this element must be replaced. In case this situation befalls you on the road and the engine stalls, there are some recommendations for detecting and eliminating this malfunction.
- Open the hood, then remove the fuel supply hose and turn on the ignition. If gasoline is supplied under low pressure, the filter has poor throughput.
- To increase the throughput of the fuel filter, it must be removed and thoroughly blown in the opposite direction.
- Remove the fuel filter from its clips and perform some operations to clean the dirt from its housing. You can use a thin screwdriver and pierce the paper element right through.
- Install the filter in place, then start the engine; if the engine starts and runs smoothly, go to the nearest car service center, where it will be necessary to replace the filter element.
- If your car's engine suddenly stalls and won't start, you need to check the functionality of the fuel pump.
To identify a fuel pump malfunction, you need to open the hood and remove the gasoline supply hose. At this moment, you need to turn the key to position 2, thereby closing the fuel pump relay.
If gasoline does not flow, the fuel pump does not work well and has become unusable. We cannot give any recommendations for its emergency repair, since this unit is replaced complete with the housing. In such a situation, the car must be towed to the nearest service center where repairs will be carried out.
- If the problem is related to the operation of the crankshaft position sensor, it is impossible to diagnose and eliminate this malfunction without special equipment.
Repairs should only be carried out by a specialized service center.
- Diagnosis and repair of problems associated with wear of the camshaft, as well as its sensor, is carried out only by the service center.
Conclusion
This is a brief overview of Renault Logan faults. If the engine of your Renault Logan stalls and does not start, use our article as instructions for troubleshooting. We hope that our material will be useful to you.
Before we begin diagnosing and repairing the Renault Logan stove, we will briefly talk about how its ventilation and heating work.
It is necessary to clearly understand that these systems operate independently of each other.
Thus, heating and ventilation of the interior, as well as the removal of frost and other types of moisture, are carried out separately from other systems. At the same time, the stove enters the heating system.
The main components of the heating system include a heat exchanger, also known as a radiator. The purpose of the radiator is to heat the air entering the cabin to a comfortable temperature set by the driver or passenger. The radiator is heated due to the circulation of coolant through it, which, in turn, heats up, removing heat from the running engine. The cooling system is closed and under pressure, so it can withstand temperatures of more than 100 degrees. Using an electric fan, you can regulate the intensity of warm air entering the cabin through the air conditioner and heater dampers.
This system also includes an electrically driven fan that supplies outside air and regulates this process. Air is supplied to the air conditioner and heater dampers. The system also includes a damper for the air temperature regulator, which flows from the heater into the car interior. How you turn it will determine the amount of air that will pass through the heat exchanger of the heater, as well as the outside air that bypasses the heat exchanger. It is also worth noting the air distribution flaps, which flow from the heater through air ducts into the cabin or in order to blow on the windshield.
A little about the air conditioning system of the Renault Logan car
The Logan air conditioning system consists of a compressor driven by a belt from the engine crankshaft pulley. The compressor pulley has an electromagnetic friction-type clutch, which will disconnect the compressor shaft from the pulley or connect them when the air conditioner is operating according to a certain signal from the electronic engine control unit.
During operation, the compressor compresses the refrigerant vapors that will come from the evaporator heat exchanger to a sufficiently high pressure level. This achieves a significant reduction in temperature.
A pressure reducing valve is built into the compressor and can perform a protection function that is triggered when the pressure increases to a value that exceeds the permissible value at the outlet of the compressor itself. The reasons for the operation of the pressure reducing valve may include failure of the valve that is responsible for high pressure, as well as the failure of the electric fan. Other malfunctions are also possible.
