How a heater works on a Toyota Avensis 3
When it is cold, heating is essential on the way when going to work. And when it doesn't work we miss it intensely. So before understanding what caused the malfunction, it is essential to know how it works on the famous Toyota Avensis 3, or at least the main lines. The heating uses the heat from the engine block to raise the temperature of the personalised tour, and generally the cooling device. So there is duplication. Similarly, the emission device, so that the air enters the cabin also has a double use. It's the ventilateur which emits air when the automobile is running at low speed or is stopped, and it is the speed of your automobile which will send the air when you circulate faster. Pretty well thought out right?
Recurring heating problems on a Toyota Avensis 3
Broken thermostat
The concept is easy, assuming that the thermostat that regulates the temperature does not really capture the temperature of the cooling circuit, the entire circuit is affected. Even if the thermostat of the famous Toyota Avensis 3 no longer works properly, the heating will still work. Because the natural heat of the engine block will increase over time, and the water circuit in the same way, even without a thermostat. Our only annoyance is that you can't really control the temperature.
Air shutters blocked on the Toyota Avensis 3
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 Toyota Avensis 3
As you will have understood, the fan operates only at reduced speed and in neutral. If this heater does not emit too much heat at low speed and you still hear noise, it means that the fan is certainly defective. If all goes well, with a fast pace the heating of the famous Toyota Avensis 3 should work. If it happens that the fan does not work at all it will have to be replaced.
Blocked hoses
Its symptoms will be relatively simple. When your heating works and does not heat or very slightly, the malfunction is probably due to the hoses. These clog over time and no longer allow hot water to reach the heating of the famous Toyota Avensis 3. So, wash the hoses or replace them with new ones.
Air pocket in the circuit of the Toyota Avensis 3
The symptom is found to be similar to those of the hoses. If air pockets are embedded in the circuit, the water will also have problems reaching the heating radiator of your Toyota Avensis 3. Then, it is only necessary to purge the circuit.
Conclusion
You now understand what will cause the malfunction. However, it may be that the problem comes from elsewhere, such as the air duct of the famous Toyota Avensis 3 obstructed, or even a defective tap, but it is still less frequent.
