Do not confuse the air conditioning , heating and ventilation of the Toyota Yaris 3. The heating and air conditioning happen to be devices that will decrease or increase the air temperature. The very first by means of the heat produced by the engine, and the other by means of a liquid refrigerant . Ventilation is the totality of circuits and systems that give the air the opportunity to reach inside. The main element is the kicker that sends air into your cabin. In the event that very little or no air arrives, it is probably a ventilation problem. We will discover in this article how a ventilation works, in order to better discern the concerns and assimilate by what means to remedy them.ventilation-problem-Toyota-Yaris-3

How a ventilation works on a Toyota Yaris 3

The ventilation is used first of all to circulate the air in the passenger compartment of the Toyota Yaris 3. Concerning the blower, it generally consists of a resistance, a turbine, and a motor. The more the total resistance of the circuit is lowered, the faster the turbine runs. By turning the switch in the vehicle, the resistance is therefore lowered.

Toyota Yaris 3: frequent ventilation problems

Dirty air ducts

When the ventilation is working but little air is coming into the cabin of the Toyota Yaris 3, it is plausible that your air flaps are blocked. Using a screwdriver flat, you can remove the flaps from the air flaps. It is enough to check inside if these are crowded. If so, you can scrub them, but also the shutters.

Dirty cabin filter

If you ever smell odors and the ventilation is weak, the problem probably comes from the cabin filter of the Toyota Yaris 3. The latter becomes blocked and piled up bacteria with time. It is completely normal that it is dirty, it is there to purify the air that reaches you. There is no instruction from the manufacturer on when to replace it. We only advise you to remove it, look at its condition. When this is really black, it will have to be changed.

Resistance of the blower HS

When the Toyota Yaris 3's ventilation knobs function poorly, or really not, it is probably related to resistance. The resistance is used to increase the voltage in order to increase the speed of this turbine. A shady operation of the ventilation is probably due to a resistance problem. This microchip is complicated to troubleshoot. It must be changed.

HS blower motor

We can find several rather regular concerns about the kicker. The brushes are worn. The more time passes, the latter may wear out and generate false contact. Your fan may run haphazardly, or no longer operate at all. It also happens that the problem arises from bearings of the motor. When the ventilation produces a whistling sound, comparable to rusty mechanics, its bearings may lack lubrication.
