How a heater works on a Toyota Picnic

In the middle of winter, heating is a definite asset on the trip when you go to work. When it does not activate we miss it quickly. In this situation in order to know where the malfunction comes from, it is necessary to know how it works on this Toyota Picnic, at least its principle. The heating uses the heat from the engine block to warm the personalised tour, and generally the cooling system. So this system has several functions. Similarly, the ventilator system, so that the heat arrives in the cabin also has a double use. There is a ventilateur which sends the heat as soon as the vehicle is moving slowly or is stopped, and it is the speed of the vehicle which will send the heat as soon as you drive faster. It's pretty clever isn't it?

Recurring heating problems on a Toyota Picnic

Broken thermostat

The concept is simple, in the case where the thermostat which allows the temperature to be adjusted does not really understand the degree of heat of the water in the circuit, the entire circuit is affected. Even if the thermostat of this Toyota Picnic does not turn properly, the heating will still work. Because the heat coming from the engine block will gradually increase, so the water circuit at the same time, whether it is regulated or not. Our only concern is that you will have trouble setting the heat output.

Air shutters blocked on the Toyota Picnic

It is a dysfunction that happens quite regularly. 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 Toyota Picnic

As you will have understood, the fan is effective only at low speed or when stopped. In case this heater does not emit any heat at low speed and yet you still hear a sound, it is good that the fan is probably broken. A priori, with more speed the heating of this Toyota Picnic must work. If it turns out that the fan really does not rotate it is better to change it.

Blocked hoses

The symptoms are fairly obvious. In the event that your heating blows and does not heat or little, the malfunction must certainly come from the hoses. These become blocked over time and no longer allow hot water to access the heating of this Toyota Picnic. Therefore, clean the hoses or put new ones.

Air pocket in the circuit of the Toyota Picnic

The symptom is sometimes the same as that of the hoses. If small pockets of air are inserted in the heart of the circuit, water also has problems reaching the radiator of the heating of your Toyota Picnic. Therefore, it is necessary to purge the circuit.

Conclusion

You now understand where your dysfunction will come from. However it may be that the problem comes on the other hand, for example the air duct of this cluttered Toyota Picnic, or a deficient tap, however it is still more rare. Leave us a comment if this text has helped you. See you soon !
