How a heater works on a Volkswagen 1303

In the middle of winter, heating is a definite asset on the journey when you go to work. When it is not running, we notice it quickly. So before knowing where the malfunction came from, you will have to know how it works on this Volkswagen 1303, at least its principle. The heating uses the engine temperature to raise the temperature of the personalised tour, then generally from the cooling device. So this system has several functions. In a similar way, the ventilator device, so that the air reaches us also has a duplication. It's the ventilateur which sends the air when the vehicle is running at low speed or or not at all, then it is the speed of your automobile which will send the air once you are moving faster. Pretty smart isn't it?

Recurring heating problems on a Volkswagen 1303

Broken thermostat

The concept is affordable, in the event that the thermostat which allows the temperature to be regulated does not really capture the temperature of the water circuit, the entire circuit is affected. Even if the thermostat of this Volkswagen 1303 no longer works properly, the heating will still work. Because the temperature coming from the engine will increase little by little, and the water circuit in the same way, even without a thermostat. The only problem is that you will have trouble controlling the heat emitted.

Air shutters blocked on the Volkswagen 1303

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 Volkswagen 1303

As you will understand, the fan only operates at low speed or in neutral. If it happens that this heater does not emit too much heat at low speed and you nevertheless discern its noise, it means that the fan is likely to be defective. As a rule, thanks to a brisk pace the heating of this Volkswagen 1303 will turn on. If the fan does not work, it will have to be replaced by a new one.

Blocked hoses

The signs are pretty straightforward. If your heater works and does not generate hot air or very slightly, the malfunction is certainly due to the hoses. They clog over time and no longer leave the possibility for hot water to reach the heating of this Volkswagen 1303. So wash the hoses or install new ones.

Air pocket in the circuit of the Volkswagen 1303

The syndrome is sometimes identical to that of the hoses. If it happens that air bubbles have entered the circuit, the high temperature water also has problems reaching the heater radiator of the Volkswagen 1303. Then, you will only have to bleed the circuit.

Conclusion

You now understand where your dysfunction can come from. However, it is possible that the reason came from another place, such as the air duct of this Volkswagen 1303 blocked, or even a broken valve, but this is unfortunately rather rare.
