How a heater works on a Toyota Iq
In the middle of winter it is essential on the road when you go to work. And when it doesn't work well, we miss it intensely. Therefore to discover what is causing the malfunction, you will have to understand how it works on your Toyota Iq, or at least the main lines. The heating uses the engine temperature to be able to warm up the personalised tour, then generally the cooling device. Consequently, this duplicates. Also, the emission device, so that the hot air reaches the cabin also has a double use. It's the ventilateur which emits hot air when the car is driving at low speed or not at all, then it is the speed of the vehicle which will send hot air when you are traveling faster. Pretty well thought out right?
Recurring heating problems on a Toyota Iq
Broken thermostat
The idea is easy, in the case where the thermostat which regulates the temperature does not measure well the degree of heat of the water in the circuit, the latter is affected. Even if your Toyota Iq's thermostat does not work properly, the heating will still work. Because the natural temperature of the engine will increase over time, so will the cooling system in the same way, even without a thermostat. Our only hassle is that you can't really change the temperature.
Air shutters blocked on the Toyota Iq
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.
Faulty fan on Toyota Iq
As you might expect, the fan is useful only at low speed and when stopped. If it happens that the heater does not send too much air at low speed but you still hear its noise, it means that the fan will most likely be screwed up. If all goes well, thanks to a high speed the heating of your Toyota Iq will be able to turn. If the fan does not work at all, it will have to be changed.
Blocked hoses
Its signs turn out to be relatively obvious. When your heating works and does not heat or very slightly, the malfunction probably comes from the hoses. These clog up the more time passes and no longer allow hot water to access the heating of your Toyota Iq. In this case, wash the hoses or put new ones.
Air pocket in the circuit of the Toyota Iq
The symptom will be the same as that of the hoses. If it happens that air pockets are embedded inside the circuit, the high temperature water also has problems reaching the radiator of the Toyota Iq heater. In this specific case, it will suffice to purge the circuit.
Conclusion
You now know what can cause this malfunction. By cons it is possible that the problem comes from elsewhere, such as the air duct of your cluttered Toyota Iq, or a broken valve, but it is still quite rare. Leave us a comment in case this ticket served you. Good road !
