How a heater works on a Renault Scenic 3 Xmod
When it's cold, the heating is our best ally on the road when you go to work. When it doesn't work anymore, we quickly miss it. Therefore to know where the problem comes from, you will have to understand how it works on your Renault Scenic 3 Xmod, at least its principle. The heating uses engine temperature to warm up the personalised tour, and generally the cooling mechanism. In fact this is duplicative. In addition, the emission mechanism, so that the hot air reaches the cabin has a dual system. There is a ventilateur which sends hot air when the car is moving slowly or or not at all, and it is the speed of your automobile that will send hot air as soon as you are moving faster. Well designed, right?
Recurring heating problems on a Renault Scenic 3 Xmod
Broken thermostat
The idea is elementary, when the thermostat which regulates the heat does not measure the degree of heat of the water in the circuit, the whole circuit is affected. Even if the thermostat in your Renault Scenic 3 Xmod is not working properly, the heating will work normally. Because the natural temperature of the engine will increase little by little, then the cooling circuit too, whether the thermostat is working or not. The only problem is that you will have trouble modifying the heat emitted.
Air flaps blocked on the Renault Scenic 3 Xmod
This is a problem that happens quite often. These shutters, which allow you to direct the air or adjust the intensity, sometimes get blocked over time. To remedy this it is simple, remove the cover and look inside how it was done. Activate the mechanisms to see where it is blocking. Put a little WD 40 to lubricate and voila.
Faulty fan on the Renault Scenic 3 Xmod
As you can imagine, the fan is useful only at low speed or when stopped. If it happens that your heater does not generate too much air at low speed and yet you still hear noise, it means that the fan will most likely be screwed up. Usually, thanks to a brisk pace, the heating of your Renault Scenic 3 Xmod should work. If the fan does not work at all, it should be changed.
Blocked hoses
The signs turn out to be pretty straightforward. When your heater works but does not create heat or very slightly, the problem is probably with the hoses. These clog up over time and no longer allow hot water to access the heating of your Renault Scenic 3 Xmod. In this case, clean the hoses or replace them with new ones.
Air pocket in the Renault Scenic 3 Xmod circuit
The symptom is the same as for hoses. If it happens that air bubbles are stored inside the circuit, the hot water also has problems accessing the heating radiator of your Renault Scenic 3 Xmod. In this case, it is necessary to purge the water circuit.
Conclusion
Now you understand where this problem can come from. On the other hand, it is possible that the problem comes from elsewhere, such as the air duct of your Renault Scenic 3 Xmod blocked, or a broken valve, but this is still less frequent. Leave us a comment if this post was useful to you. Good walk !
