How a heater works on a Toyota Rav 4 (3th Generation)

When it is cold it is our best ally on the way when we go to work. When it no longer turns we miss it easily. Therefore to know where the malfunction comes from, it will be necessary to understand how it works on this Toyota Rav 4 (3rd Generation), at least in a simplified way. The heating uses engine heat to heat the engine personalised tour, then very often from the cooling system. In fact, this duplicates. In addition, the emission system, so that the air comes to us has a double system. There is a ventilateur which emits air as soon as the automobile is traveling at low speed or is stopped, then it is the speed of your automobile which will send the air when you are traveling faster. It's pretty clever isn't it?

Recurring heating problems on a Toyota Rav 4 (3th Generation)

Broken thermostat

The notion is elementary, assuming that the thermostat which regulates the heat does not really understand the degree of heat of the water circuit, the entire circuit is affected. Even if the thermostat of this Toyota Rav 4 (3rd Generation) does not activate well, the heating will still work. Simply because the heat produced by the engine will gradually increase, so will the water circuit, even without a thermostat. The only hassle is that you won't be able to really control the heat emitted.

Air shutters blocked on the Toyota Rav 4 (3th Generation)

It is a dysfunction that happens quite frequently. 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 Rav 4 (3th Generation)

As you can imagine, the fan only works at low speed and the engine off. In case your heating does not generate heat at low speed but you still hear a sound, it means that this fan is certainly screwed up. Normally, thanks to the higher speed, the heating of this Toyota Rav 4 (3rd Generation) should work. Assuming that the fan does not really activate it is better to replace it.

Blocked hoses

Its clues are relatively obvious. When your heating blows but creates little or no heat, the malfunction probably comes from the hoses. These clog up the more time passes and do not allow hot water to reach your heating of this Toyota Rav 4 (3rd Generation). So, unclog the hoses or install new ones.

Air pocket in the circuit of the Toyota Rav 4 (3th Generation)

The symptom happens to be the same as those of the hoses. If small air pockets are introduced into the circuit, water also has difficulty accessing the heating radiator of your Toyota Rav 4 (3rd Generation). So, it is necessary to purge the water circuit.

Conclusion

You now understand where your dysfunction may come from. That said it happens that the problem comes from elsewhere, such as the air duct of this cluttered Toyota Rav 4 (3rd Generation), even a defective tap, however it is still quite rare.
