How a heater works on a Citroen Nemo
When it is cold it is a definite asset on the road when you go to work. And when the latter no longer turns we can easily notice it. In this situation before knowing where the malfunction came from, you will need to know how it works on your Citroen Nemo, at least in a simplified way. The heating uses the engine temperature to warm the personalised tour, and very often the cooling device. In fact it is a two in one. Also, the emission device, so that the hot air arrives in the cabin has a double system. It's the ventilateur which emits hot air when the vehicle is running at low speed or not, and it is the speed of your automobile which will send hot air as soon as you circulate faster. Pretty well thought out right?
Recurring heating problems on a Citroen Nemo
Broken thermostat
The concept is simple, when the thermostat that regulates the temperature does not really understand the degree of heat of the water in the circuit, the latter is impacted. Even if your Citroen Nemo's thermostat does not work correctly, the heating will work normally. Because the natural temperature of the engine will increase over time, so will the cooling system, even without a thermostat. The only concern is that you will have difficulty controlling the temperature.
Air shutters blocked on the Citroen Nemo
It is a dysfunction 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.
Defective fan on the Citroen Nemo
As you can imagine, the fan is effective only at low speed or in neutral. If this heater does not send air at low speed but you still hear noise, it means that your fan turns out to be probably broken. A priori, thanks to a higher speed the heating of your Citroen Nemo will turn. If the fan does not work at all, it will have to be replaced by a new one.
Blocked hoses
The symptoms will be rather simple. When your heating blows but does not create little or no heat, the malfunction probably comes from the hoses. These become obstructed the more time passes and no longer allow hot water to access the heating of your Citroen Nemo. In this case, clean the hoses or install new ones.
Air pocket in the Citroen Nemo circuit
The symptom will be identical to those of the hoses. If air pockets are introduced inside the circuit, the high temperature water will also have trouble reaching the radiator of the Citroen Nemo's heating. In this case, it is only necessary to purge the circuit.
Conclusion
You now know where your dysfunction will be born. That said it does happen that the problem comes from elsewhere, like the air duct of your Citroen Nemo clogged, or a deficient tap, but this remains unfortunately rather rare.
