How a heater works on a seat terraavis
In winter it is a definite asset on the journey when going to work. And when it does not work we quickly regret it. So in order to understand what the problem came from, you need to understand how it works on this seat terraavis, at least in a simplified way. The heating exploits the temperature of the engine block in order to warm the personalised tour, then in most of the cases of the cooling device. In fact this system has several functions. Similarly, the emission device, so that the hot air reaches us also has a dual purpose. It's the ventilateur which emits hot air as soon as the car is running at low speed or not at all, then it is the speed of the car which makes it possible to send hot air when you are driving faster. Well designed, right?
Recurring heating problems on a seat terraavis
Broken thermostat
The idea is elementary, in the case where the thermostat which regulates the heat does not really capture the temperature of the water circuit, the whole circuit is affected. Even if the thermostat of this seat terraavis does not rotate properly, the heating will operate normally. Because the temperature produced by the engine block will increase over time, so the water circuit at the same time, whether the thermostat works or not. The only hassle is that you can't really adjust the air temperature.
Air shutters blocked on the seat terraavis
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.
Faulty fan on seat terraavis
As you can imagine, the fan only works at low speed or in neutral. If the heater does not emit air at low speed at all but you still hear noise, this means that your fan is probably broken. Normally, with more speed, the heating of this seat terraavis should turn. Assuming that the fan really does not rotate it should be replaced.
Blocked hoses
His clues are pretty obvious. If your heating blows and does not generate hot air or very slightly, the problem probably comes from the hoses. They become blocked over time and do not allow hot water to access until the heating of this seat terraavis. So, clog the hoses or replace them with new ones.
Air pocket in the seat terraavis circuit
The symptom will be identical to that of the hoses. If ever air pockets are stored in the circuit, the high temperature water will likewise have trouble reaching the radiator of the heating of this seat terraavis. Then, it will suffice to purge the water circuit.
Conclusion
You now understand what could be causing your concern. By cons it may be that the problem comes from another place, for example the air duct of this blocked seat terraavis, or a broken valve, but it is still less common.
