How a heater works on a seat leon
When it is cold it is our best ally on the way to work. When it doesn't spin we miss it quickly. So in order to find out what the problem comes from, you have to understand how it works on this seat leon, at least its principle. The heating uses the temperature of the engine block to raise the temperature of the personalised tour, then in most of the cases of the cooling device. Therefore this system has several functions. In addition, the emission device, so that the air arrives in the cabin also has a double use. It's the ventilateur which sends air when the car is driving slowly or not at all, then it's speed of the vehicle which will send air when you drive faster. It's pretty clever isn't it?
Recurring heating problems on a seat leon
Broken thermostat
The idea is elementary, in the case where the thermostat which regulates the heat does not really enter the temperature of the water circuit, the latter is affected. Even if the thermostat of this seat leon still does not work well, the heating will operate normally. Because the temperature produced by the engine block will gradually increase, and the cooling circuit too, whether it is regulated or not. Our only annoyance is that you can hardly regulate the heat emitted.
Air flaps blocked on the seat leon
It's a concern 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 seat leon
You have now entered, the fan is only used at low speed and stopped. If the heater does not send heat at low speed and yet you still hear a sound, it means that this fan is most likely screwed up. A priori, with a higher speed the heating of this seat leon will turn. If it happens that the fan does not work it is better to replace it with a new one.
Blocked hoses
Its signs turn out to be relatively obvious. As soon as your heating turns but does not generate very little hot air, the problem probably comes from the hoses. These become blocked over time and no longer allow hot water to access until the heating of this seat leon. In this situation, clean the hoses or install new ones.
Air pocket in the seat leon circuit
The symptom happens to be the same as that of the hoses. If ever air pockets are inserted inside the circuit, the water will have the same problems to arrive at the radiator of the heating of the seat leon. In this situation, it is necessary to purge the circuit.
Conclusion
You now know where your concern may come from. However it is possible that the problem comes from another place, such as the air duct of this cluttered seat leon, or else a defective tap, but it is nevertheless more rare. You can write a comment in case this article served you. Good road !
