How a heater works on a Seat 127

When it is cold it is a definite asset on the way when going to work. And when the latter no longer activates, it is quickly noticed. In this case in order to understand where the problem came from, it is essential to understand how it works on this Seat 127, at least the basics. The heating uses heat from the engine block to increase heat from the personalised tour, then in most cases the cooling mechanism. In fact this is duplicative. In addition, the fan mechanism, so that the air reaches the passenger compartment has a dual system. There is a ventilateur which sends air out when the vehicle is running at low speed or is stationary, then it is vehicle speed that allows air to be sent out once you are traveling faster. Pretty smart isn't it?

Recurring heating problems on a Seat 127

Broken thermostat

The concept is elementary, in the event that the thermostat which regulates the temperature does not correctly capture the temperature of the cooling circuit, the latter is affected. Even if the thermostat of this Seat 127 still does not work well, the heating will still work. Because the heat coming from the engine block will increase little by little, then the water circuit in the same way, even without a thermostat. Our only hassle is that you will have a hard time controlling the air temperature.

Air shutters blocked on the Seat 127

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.

Faulty fan on the Seat 127

As you will understand, the fan only operates at low speed or the engine is off. If your heating system does not generate heat at all at low speed, and you still hear a sound, it means that this fan is probably running out. In principle, with more speed the heating of this Seat 127 should work. If it happens that the fan really does not work, it is better to replace it.

Blocked hoses

The clues turn out to be pretty obvious. If your heater is blowing but not creating heat or very slightly, the problem is most likely the hoses. They become clogged over time and no longer allow hot water to reach the heating of this Seat 127. Therefore, unclog the hoses or put new ones.

Air pocket in the Seat 127 circuit

The syndrome is found to be identical to those of the hoses. If air bubbles are encrusted inside the circuit, the hot water will also have difficulty reaching the heating radiator of this famous Seat 127. From then on, all you have to do is purge the circuit.

Conclusion

You now know where your dysfunction is going to be born. However, it happens that the reason comes on the other hand, like the air duct of this Seat 127 blocked, or a faulty valve, but it is much rarer. Do not hesitate to leave a comment if this tutorial has helped you. Good walk !
