How a heater works on a Citroen Saxo
In winter it is our best ally on the way when we go to work. And when the latter does not activate we easily regret it. In this case in order to know where the malfunction comes from, you need to understand how it works on this Citroen Saxo, at least the basics. The heating uses engine heat to warm the personalised tour, and very often the cooling device. In fact it is a two in one. Also, the fan device, so that the air comes into the cabin also has a double use. There is a ventilateur which sends air when the car is running at low speed or not, and it is the speed of the vehicle which will send air when you drive faster. It's pretty clever isn't it?
Recurring heating problems on a Citroen Saxo
Broken thermostat
The idea is affordable, assuming that the thermostat which regulates the heat does not really measure the temperature of the cooling circuit, the entire circuit is affected. Even if the thermostat of this Citroen Saxo does not turn correctly, the heating will still work. Quite simply because the natural heat of the engine will increase progressively, then the water circuit at the same time, whether it is regulated or not. The only annoyance is that you can't really change the temperature.
Air shutters blocked on the Citroen Saxo
It is a dysfunction that happens quite frequently. 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 Saxo
As you can imagine, the fan is effective only at low speed or stopped. If the heating does not emit any more air at low speed but you nevertheless discern its noise, it is good that your fan will undoubtedly be defeating. Ordinarily, with more speed the heating of this Citroen Saxo must work. If it happens that the fan really does not rotate it will have to be replaced.
Blocked hoses
The clues turn out to be rather obvious. When your heating turns but does not generate little or no hot air, the malfunction is probably due to the hoses. These become blocked the more time passes and no longer leave the possibility for hot water to reach your heating of this Citroen Saxo. In this case, remove the hoses or put new ones.
Air pocket in the Citroen Saxo circuit
The symptom is sometimes similar to those of the hoses. If air bubbles are encrusted in the heart of the circuit, hot water has the same way of problems to access the radiator of the heating of this Citroen Saxo. In this case, it will suffice to purge the circuit.
Conclusion
You now know where the dysfunction could originate. That said it is possible that the problem originated from another place, such as the air duct of this clogged Citroen Saxo, or even a defective tap, but it is unfortunately more rare.
