Let's not confuse the air conditioning , heating and ventilation of this Toyota Aygo. Heating and air conditioning are systems that give the possibility of reducing or amplifying the air temperature. The first with the help of the heat produced by the engine block, and the other with the help of a fluid refrigerant . Your ventilation is all of the circuits and systems that will allow air to enter the passenger compartment. The fundamental component will be kicker which sends air into your cabin. In the event that little or no air comes in, it is certainly a malfunction of ventilation. We will see in this guide how ventilation works, so as to better perceive the malfunctions and understand how to resolve it.
How a ventilation works on a Toyota Aygo
The ventilation is used to start to regenerate the air in the passenger compartment of this Toyota Aygo. As for the pulser, it is usually composed of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By rotating the switch in the vehicle, the resistance is therefore reduced.
Toyota Aygo: frequent ventilation problems
Dirty air ducts
When the ventilation turns but little air arrives in the passenger compartment of this Toyota Aygo, it is conceivable that these air flaps are obstructed. With the aid of screwdriver flat, it is possible to remove the air flap valves. You just have to take a look inside if they are clogged. If this is what happens it is possible to scour them, but also the shutters.
Dirty cabin filter
When you discern fumes and the ventilation is weak, the malfunction probably comes from the cabin filter of this Toyota Aygo. This one is blocked and piled up bacteria with time. It is quite common that it is dirty, it is used to filter the air that reaches you. There is no instruction from the manufacturer as to when to change it. It is advised simply to remove it, check its condition. When the latter is really black, it will be better to change it.
Resistance of the blower HS
When the ventilation adjustment of your Toyota Aygo works poorly, or even not at all, it is probably due to resistance. The resistance increases the voltage so that the speed of the turbine can be amplified. A suspicious malfunction of ventilation is probably linked to a resistance malfunction. This electronic chip is complicated to repair. It is necessary to change it.
HS blower motor
There are two rather recurring malfunctions on the blower. The brushes may be damaged. Over time, they will be able to be damaged and cause electrical faults. Your kicker may spin randomly or even not work at all. In addition, the malfunction may come from bearings of the fan motor. When the ventilation produces a hissing sound, like a rusty mechanism, it can happen that its bearings lack lubrication.
