Switching on the cooling fan Kangoo RENAULT forums on the web-site1.Ru
Today I found out that wiggling the white plug from the photo fixes the fan but causes loss of communication between the engine and the immobilizer.
Tomorrow I’ll buy some duct tape and look for a bad contact UPD2 Today I spent the whole day on the wiring. Bottom line. I didn’t find any rotten wires. Didn’t find any oxidized ones either. There’s a feeling the pins in that connector aren’t springy at all. I took out every contact, inspected for corrosion, rubbed the plugs with an eraser, in each mom tucked the spring contacts. Sprayed some VED and reassembled.
Wrapped up all the wire harnesses with good duct tape. In short now it is possible to cheat at any contest without preparation The engineer in me was satisfied.
The heater fan does not work((. logbook Renault Kangoo on DRIVE2
It is manifested in the fact that the heater turns on, but it happens only at maximum speed.
In all other modes the heater does not turn on and does not work. Here you can try to remove the resistor and repair.
But often the device must be replaced. The resistor itself fails because of poor contact, malfunction of the fan, as well as due to a clogged filter or radiator, which leads to poor blowing of the resistor with the following breakdown. Lack of contacts. It is banal that the electric heater fan of Renault Kangoo does not receive power. The cause should be sought in the wires, as well as in the contacts between.
These are situations when the heater does not turn on at all on Renault Kangoo. But it also happens otherwise, when the equipment functions, but does not do it in the same way as.
It works, but it is not warm Here we are talking about a situation when in Renault Kangoo, the heater turns on, the fan seems to rotate, but from deflectors comes out cold, or hardly warm, which objectively is not enough for good heating of the interior and warming of its inhabitants represented by the driver and passengers.
There are several main reasons and appropriate ways to solve problems related to the poor performance of the heater on the Renault Kangoo, which does not want to heat the interior properly.
Renault Logan overheated, the fan did not turn on. why?
Hi all! I am Albert Auhadullin, author of Renault Logan AAuhadullin blog.ru. Today let’s talk about what is the cooling system of the car Renault Logan, also I will tell you about its purpose, functioning, maintenance and repair methods. If you notice any mistakes, please correct me in the Комментарии и мнения владельцев of this video review. There is nothing wrong, as everyone has his own knowledge, his own experience of maintenance and repair of cooling system of any car.
Let’s start with the expansion tank of the cooling system of the car engine, which you see on the video screen. Coolant is poured into the neck of the expansion tank, the level of which should be kept between the marks of minimum and maximum, marked on the visible wall of the expansion tank. the cooling fluid must be in the middle of these lines.
Expansion tank of the engine cooling system of a vehicle actually follows from its name. The coolant expands when heated, as its volume increases, part of the fluid escapes to the expansion tank, protecting the vehicle cooling system from excessive pressure.
To regulate the pressure, the air-tightness of the cooling system, the expansion tank plug is fitted with two valves: inlet outlet. The inlet valve is designed to open when the pressure in the cooling system decreases below atmospheric pressure by 0.030.13 kgf/cm2 (when the engine is cold). The valve controls the pressure in the cooling system above the atmospheric pressure on a hot engine (due to this the boiling point becomes higher). The valve is actuated within the pressure value 1.1- 1.5 kg/cm2.
By the way, problems with this valve often lead to overheating of the car engine with all the ensuing consequences. It can be treated simply enough. Or the cover is inspected and cleaned (some particle of dirt or a piece of rubber can get under the valve, the spring can rust, etc.).), or the cap is replaced with a new one.
When the valve does not bleed high pressure, it can leak where there are connections of cooling system nozzles, and also the rubber nozzles can swell that leads to their cracking. In addition the increased pressure can lead to cracks in the cooling radiator.
The second function of an expansion tank in cars is to save the engine from overheating in an extreme situation. For example, at the breakdown of the head gasket the engine temperature starts to rise in the square (the coolant starts to simply boil off in the combustion chambers) and it is at this moment the engine will take the lack of antifreeze from the expansion tank. But it saves the engine only if the driver notices the defect and turns off the engine in time, since this process is very quick.
The expansion tank is connected by a flexible rubber hose to the radiator of the vehicle cooling system, so when it is filled with coolant, it flows through the hose to the radiator and then fills the entire cooling system.
A coolant pump, better known to motorists as the pump, is provided so that the antifreeze can circulate through the closed cooling system. The thermostat is used to control the temperature of the coolant.
The thermostat also controls the temperature and direction of the coolant flow, depending on the temperature of the engine when it is running. For this purpose the thermostat is equipped with a valve, which is activated before the antifreeze temperature rises or falls. When it rises, it opens and when it falls, it closes. But it does not open all the way through at once, and has two modes of operation. The first one partially opens the valve, partially letting the antifreeze flow to a big circle through the inlet connector of the main radiator. It happens around 80-85°C, and the valve fully opens around 94-97°C, depending on the calibration of the thermostat.
The hot antifreeze inside of radiator is being cooled by counter flow of air while driving helping to reduce temperature of antifreeze. That’s why it is so important that the radiator grill is not covered with different, hinged accessories and the radiator surface is clean. For example, if there is a lot of down from the trees, it may completely clog the radiator cores, increasing the engine temperature. Fast, reliable and inexpensive protection in this period is installation of net in front of it. Mesh prevents from mud, crashed insects, down from trees and other debris.
And in winter we achieve the opposite effect. we protect radiator surface from counter-air flow as much as possible to keep warmth. Typically, most motorists install something like cardboard or something similar to protect the radiator. On this topic on the AAuhadullin blog page.There is a detailed video on the peculiarities of operation here.
Next. The liquid cooled by the radiator fills the engine jacket with the cylinder head again through the outlet. When the thermostat valve is fully opened, the fluid is already starting to circulate in a large circle. As the fluid cools, the thermostat valve
the thermostat is closed and the fluid circulates only in a small circle. This process is constantly repeating while the engine is running.
In addition, the engine cooling system is equipped with an electric fan, which additionally reduces the temperature of the coolant with its airflow. When necessary, the electric ventilator is triggered by the temperature sensor, which, like the thermostat, has its own set point for triggering.
From the temperature sensor signal goes to the electronic control unit (ECU), and then to the radiator cooling fan. When replacing it, when it fails, always buy a new temperature sensor with the same markings as the original sensor. Markings stamped on the rib of the sensor.
Electric fan works as an assistant to the cooling system of the car, turning on at limit values of temperature of antifreeze, when the counter flow of air is no longer able to remove the heat of overheating. It is also triggered in traffic jams because there is no air flow (the car is standing rather than moving). If the electric fan does not work, there can be serious problems with overheating of the engine, therefore it is necessary always to watch the indicator of a dashboard scale at any difficult situations.
Usually the fan failure is associated with a blown fuse, the location, also the rating, which on your car is better to know in advance at your leisure.
Once the electric fan has reduced the heat, it shuts off and waits for the temperature sensor to send a signal if the temperature rises.
Working principle of coolant temperature sensor
In turn, the ECU of the injection system brain, based on the temperature of the antifreeze, manipulates the work:
- injection system
- Relay from the electric fan of antifreeze cooling
- coolant-antifreeze alarm temperature lamp. The electronic brain turns the warning light on when it gets above 120°C
The car Renault Logan without air conditioner. has only one speed of the main radiator fan. In a car with air conditioning fan starts running at low speed when the antifreeze exceeds 100 ° C heat. Also runs, on first speed if the coolant temperature sensor is defective and turns off when the temperature is below 96°C.
Second speed turns on when the antifreeze temperature exceeds 120°C and if the low-speed circuit is faulty, and turns off when the temperature is below 100°C. Main radiator fan turns on low or high speed depending on air conditioner operation. If the low speed circuit is defective, the fan runs at high second speed in emergency mode.
The vehicle cooling system is also equipped with a bypass valve to relieve air trapped in the system, e.g. when refilling the vehicle with coolant. The valve is opened (unscrewed) and the fluid is bled until the fluid appears clear and without bubbles and then the valve is closed.
The hose is rubber, mounted on the connector outlet at the engine shield goes into the cabin on the heater radiator of the car. The upper hose that brings the coolant in and the lower hose that diverts it from the heater radiator. The heater radiator is smaller than the main radiator and its task is not mainly to cool, but to generate heat in the cabin. When the heating system is operating correctly, the temperature of the inlet and outlet connections should be approximately the same. This suggests that the stove radiator is clean and working at full capacity.
In an emergency, when the vehicle engine is overheated, you can use the heater radiator for additional heat intake. The heater radiator faucet opens to full power and the fan starts. Of course, it will not be very comfortable in the cabin, but it is a necessary short-term measure to save the engine from overheating.
Now we can see the moment when the fan is turning on, it is triggered by the temperature sensor and will work until the coolant cools down. The work of the fan can be clearly heard by its steady and powerful humming. the temperature gauge on the instrument panel now reads 4 bars.
As you can see on the video in the engine compartment of the car the fan works long enough and cools the coolant. This time it runs long and I decided to put the car in the shade to help the engine cool down faster. Just a chance to use the radiator of the stove. I turn on the heater and turn the blower on full blast speed.
Here is just found the shade and in addition the heater will help cool down the engine faster. Now we will wait, when the cooling fan of the main radiator will be switched off. On any case we shall check up, whether there is no air cork by opening of the bypass valve, serving for dump of air in cooling system.
The fan never wanted to turn off, then the level of the expansion tank rose to the top mark from the expansion of the antifreeze. After a brief parking in the shade of the trees with the hood open and then a short drive, the fan turned off. But after the engine has warmed up to the limit temperature, the electric fan will turn on again to lower the coolant temperature.

It works, but it doesn’t heat
Here we are talking about situations when Renault Kangoo heater turns on, the fan seems to rotate, but from the deflectors comes the cold air, or barely warm, which objectively is not enough to fully heat the cabin and warmth of its occupants represented by the driver and passengers. There are several main reasons and corresponding ways of solving the problems related to the bad functioning of the heater on Renault Kangoo, which does not want to heat the interior properly.
- Thermostat. If it is faulty, cooling liquid will circulate only in a large circle. Theoretically you can try to repair the thermostat, but the best solution is to replace the. Further we shall separately consider the procedure of its dismantling.
- The radiator. An issue that also requires a separate study. Most often on Kangoo the radiator of the heating system gets dirty because of the destruction of the stilling partition on the expansion tank with cooling fluid. Or the car owner himself uses low-quality antifreeze. Some go even further, pouring plain water instead of coolant. Then the radiator won’t last long.
- Antifreeze deficiency. The reason is banal, but very common. It is recommended to begin diagnostics of your Kangoo with checking the amount of cooling fluid in the expansion tank. If it is not enough, be sure to top up. Plus it can be necessary to pump the system in order to remove excess air.
- Air plug. A frequent guest on Renault Kangoo with quite high mileage. The systems and units are worn out, the air seeps in, and it can break the normal operation of the heater. Plus it occurs at illiterate service and violation of rules of carrying out of some repair-restoration works.
- Failure of a damper. We have already dealt with it, and you know that the choke must be replaced if necessary.
- Clogged cabin filter. Don’t rush to blame it all on the cabin filter, since it simply may not be present on your car. Such a cleaning element is put on Kangoo with air conditioners from the factory.
Poor performance of the heater is not able to satisfy the heating needs of the interior and of the passengers inside the car. That is why it is necessary to find the reason and ways to solve the problem.
Renault Kangoo owners and fans forum
If the fan then starts working, you can conclude that there is a breakage in the second black wire, try to find a breakage, and check whether it is firmly connected to the ground. After that, connect the two wires together, and see what happens, if the fan turns on, then the problem was in a bad connection.
Check the fan relay, it is possible that the problem is in the. To find out it is enough just to replace it with the neighboring relay, then connect the wires of the radiator sensor with each other, see.
Where is the fan switch sensor of Renault Kangoo 1?4
If the fan turns on. the problem is a faulty relay. Next, you need to check the voltage to see if it is coming to the fan through the fuse box.
To do this, take a piece of wire and install it in the sockets of the relay, if the fan worked, the reason why the fan does not work is in the fuse box. It is likely that the voltage is not coming to the fan relay.
To check this, you can use the old-fashioned way. Take a light bulb, which will serve as a control. If there is no light, you just need to poke the other end on the ground, if you see a spark, it should not be a problem.
If you don’t see a spark, you will most likely have a broken wire in the fuse box.
If after checking all of the above find the reason why the radiator fan does not turn on, there is only one wire left to check. the radiator sensor wire.
To do this, you need to remove the commutator, as it does not allow to get to the plugs of the fuse block. So, we remove the connector plug from the fuse box, and check the radiator sensor wire for a breakage.
Check as follows: Next, remove the plug from the sensor and connect the light bulb. If there is no light, make a tap on the ground.
If there is no voltage, this wire is probably broken. If the fan does not turn on, the cause may be quite unexpected, for example. a burnt gasket under the head.
On does not occur for the reason that the coolant does not enter the cylinder, and the gases from the cylinder penetrate into the coolant, thus creating an effect known as an air lock. This plug prevents the coolant from pumping properly. How to understand that you have a blowhole?
It is enough to have a look in the expansion tank, if during the operation there are bubbles coming out of it now and then. you have a burned gasket, or there is a crack in a cylinder. To do this, start the engine of the car and give some time does not work cooling fan Renault Kangoo work at idle speed.
When the dashboard will show that the temperature of the coolant comes up to a critical zone, the sensor will inform the radiator fan to start working.
At that moment the driver will hear an additional noise from under the hood, and opening it, he will see that near the radiator the fan impeller is spinning. If the temperature of the coolant has reached a critical value, and the radiator cooling fan does not think to turn on, you need to figure out why it happens. You can identify the following main reasons why the radiator cooling fan does not work:

Here we are talking about the heater motor. The problem can be solved by simply replacing the defective element. But the problem is that to get to the electric motor is quite difficult.
Not everyone dares to do it with their own hands, and apply for help to the car service. Control unit failure. Because of this also can not turn on the fan. When you press the buttons renault kangoo heating system does not work the heater fan does not respond.
It is required to disassemble the unit, check the integrity of the wiring, all contacts and the presence of power supply to the controls of the heating equipment. Trouble related to the heater resistor.
Such malfunction is characterized by a special symptom. It is manifested in the fact that the heater turns on, but it does it only at maximal revolutions. In all other modes heater doesn’t turn on and doesn’t work.
Here you can try to remove the resistor and repair. But often the device should be replaced. The resistor itself fails due to poor contact, disrupted the fan itself, as well as due to a clogged filter or radiator, which leads to poor blowing of the resistor with subsequent breakdown.
Lack of contacts. It is banal that the electric fan of the heating equipment on Renault Kangoo does not receive power from the mains. The cause should be sought in the wires as well as the contacts between.

Heater fan renault kangoo 2008
There are several basic causes and appropriate ways to solve problems associated with poor operation of the heater on Renault Kangoo, which does not want to heat the cabin properly. When it renault kangoo fan does not work the cooling fluid will circulate only in a large circle. In theory you can try to repair the thermostat, but the best solution is to replace it. Below we will separately consider the procedure of its dismantling. A question that also requires a separate study.
Most often in Kangoo, the radiator of the heating system is contaminated because of the destruction of the soothing partition on the expansion tank with the cooling fluid.
Or the car owner himself uses low-quality antifreeze. Some people go even further, pouring plain water instead of coolant. Then the radiator will not live for a long time. Antifreeze deficiency. The reason is trivial, but very common. It is recommended to begin diagnostics of your Kangoo with checking the amount of cooling liquid in the expansion tank.
Plus you may need to pump the system to remove excess air. Air plug. A frequent occurrence on Renault Kangoo with quite high mileage. Systems and components wear out, air leaks in and can interfere with normal heater operation. Plus it happens when there is illiterate maintenance and violation of the rules for some repair and maintenance work.
Fill with coolant and bleed
The circulation of the fluid through the radiator is constant, which improves the overall cooling of the engine.
Check coolant filler cap or drain plugs for tightness.
Remove the plugs from the two holes to remove the air.
Pour the coolant through the neck of the expansion tank.
Screw the plugs into the vent holes as soon as the liquid starts to come out of them in a continuous stream.
Start the engine (bring engine speed to 2500 rpm).
Fill the tank with fluid for about 4 minutes, with the fluid level as close to the upper edge of the tank neck as possible.
Close the expansion tank cap. VENTING
Run the engine for 10 minutes at 2,500 rpm until the electric fan(s) engage (time required for automatic degassing of the system).
Check that the fluid level is near the “Maxi” mark.
