Do not confuse the air conditioning , heating and ventilation your Toyota Previa 2. Heating and air conditioning happen to be mechanisms that will lower or raise the temperature. The first with the help of heat generated by the engine block, and the other with the help of a liquid refrigerant . The famous ventilation is all the circuits and devices that allow the air to reach the interior of the vehicle. The essential element is the kicker which propels the air in your automobile. If the air comes in very little or at all, it is probably a ventilation problem. Thanks to this article, we will see how ventilation works, so as to better perceive the concerns and understand how to solve them.problem-ventilation-Toyota-Previa-2

How a ventilation works on a Toyota Previa 2

Ventilation is used to start circulating air in the passenger compartment of your Toyota Previa 2. For the blower, it is often made of a resistance, a turbine, and an engine. The lower the total resistance of the circuit, the faster the turbine turns. By rotating the switch in the vehicle, the resistance is therefore reduced.

Toyota Previa 2: common ventilation problems

Dirty air ducts

If the ventilation is running but very little air is entering the passenger compartment of your Toyota Previa 2, it is likely that your air flaps are blocked. Thanks to a screwdriver flat, do not hesitate to remove the covers of the air vents. It is only necessary to take a look in them if they are blocked. If this is the case, do not hesitate to scrub them, but also the shutters.

Dirty cabin filter

When you perceive odors and your ventilation is poor, the problem must probably come from the cabin filter of your Toyota Previa 2. It becomes clogged and accumulates. bacteria with time. It remains completely common that this one is clogged, it serves to purify the air which arrives to you. There is no manufacturer recommendation on when to replace it. We simply advise you to take it apart and check its condition. If it is particularly dirty, it will be better to replace it.

Resistance of the blower HS

If the buttons of the ventilation of your Toyota Previa 2 do not work well, or even not at all, it is probably related to the resistance. The resistance is used to increase the voltage to be able to increase the speed of this turbine. An inconsistent operation of your ventilation is likely related to a resistance issue. This electronic chip is difficult to troubleshoot. You will have to replace it.

HS blower motor

There are several relatively recurring issues with the kicker. The brushes may be worn. Over time, they will deteriorate and generate electrical faults. Your kicker will be able to run randomly, and even not spin at all. It is also possible that the problem stems from bearings of the motor. In the event that the ventilation whistles, comparable to rusty mechanics, it happens that the bearings require lubrication.
