How a heater works on a Toyota Corolla 9

In the middle of winter it is a definite asset on the journey when going to work. When it does not activate well we regret it intensely. So in order to know where the malfunction comes from, you have to understand how it works on this Toyota Corolla 9, at least the basics. The heating uses the heat from the engine block to warm the personalised tour, and very often the cooling device. So this system has several functions. In addition, the emission device, so that the heat reaches the cabin has a double system. It's the ventilateur which emits heat when the car is running at low speed or not, and it is the speed of your car which allows heat to be sent as soon as you are traveling at high speed. Well designed, right?

Recurring heating problems on a Toyota Corolla 9

Broken thermostat

The concept is easy, in the case where the thermostat which regulates the temperature does not really understand the temperature of the water circuit, the latter is affected. Even if the thermostat of this Toyota Corolla 9 does not turn well, the heating will work normally. Because the natural heat of the engine block will gradually increase, and the cooling circuit in the same way, whether the thermostat works or not. The only hassle is that you can't really set the heat output.

Air shutters blocked on the Toyota Corolla 9

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 Corolla 9

You have now entered, the fan is effective only at low speed and stopped. If your heating does not generate too much heat at low speed and yet you still hear noise, this means that your fan will probably be defective. Ordinarily, with more speed the heating of this Toyota Corolla 9 will be able to work. In case the fan really does not rotate it will have to be replaced.

Blocked hoses

The clues turn out to be rather obvious. In the event that your heating turns and creates little or no heat, the malfunction is probably due to the hoses. These clog over time and do not allow hot water to heat up this Toyota Corolla 9. Therefore, remove the hoses or install new ones.

Air pocket in the circuit of the Toyota Corolla 9

The symptom is the same as that of the hoses. If ever small pockets of air are inserted in the heart of the circuit, hot water will also have trouble accessing the heating radiator of this Toyota Corolla 9. From then on, it will be enough to purge the circuit.

Conclusion

You now know where your dysfunction will occur. However it may be that the problem came from the other hand, like the air duct of this clogged Toyota Corolla 9, or a defective valve, but it is still quite rare. Leave us a comment if you find this post useful. Good walk !
