Do not confuse the air conditioning , heating and ventilation of your Toyota Avensis 3. Heating and air conditioning are systems that will lower or amplify the air temperature. The first thanks to the heat produced by the engine block, and the other using a fluid refrigerant . Your ventilation is the set of ducts and devices that allow air to reach the interior. The main element is the kicker which emits air into your vehicle. If there is very little or no air supply, it is probably a malfunction of ventilation. We will see within this file how a breakdown works, so as to better perceive the problems and assimilate by what means to remedy them.problem-ventilation Toyota Avensis-3

How a ventilation works on a Toyota Avensis 3

The ventilation is used first to regenerate the air in the passenger compartment of your Toyota Avensis 3. Regarding the blower, the latter generally consists of a resistor, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine operates. By turning the knob in the passenger compartment, the resistance is therefore reduced.

Toyota Avensis 3: usual ventilation problems

Dirty air ducts

When the ventilation works but a small amount of air enters the interior of your Toyota Avensis 3, it is likely that the air shutters are clogged. With the aid of screwdriver flat, you can remove the valves from the air vents. You just have to check inside if they are blocked. If this is the case you can scour them, as well as the valves.

Dirty cabin filter

When you feel efflux and ventilation is poor, the malfunction probably comes from the cabin filter of your Toyota Avensis 3. It gets blocked and piled up bacteria with the years. It remains totally common that it is dirty, it is there to purify the air that reaches you. There is no manufacturer's instruction as to when to change it. It is only advisable to dismantle it, check its condition. When it is completely dirty, it will be necessary to change it.

Resistance of the blower HS

When the ventilation controls of your Toyota Avensis 3 do not work well, or even really do not, it is probably due to the resistance. This resistance increases the voltage to amplify the speed of this turbine. Inconsistent ventilation malfunction may be due to resistance malfunction. This electronic chip is complex to repair. We will have to change it.

HS blower motor

There are several relatively recurring problems with the kicker. The brushes are damaged. The more time passes, they can be damaged and produce false contact. The kicker may work randomly or even stop working at all. It also happens that the dysfunction comes from bearings of the fan motor. When the ventilation produces a hissing sound, comparable to a rusty mechanical, it is possible that its bearings lack lubrication. Do not hesitate to comment on this file if your dysfunction is different to help our readers. See you soon!
