Do not confuse the air conditioning , heating and ventilation of this Toyota Rav 4 (2nd Generation). Heating and air conditioning are mechanisms that offer the possibility of decreasing or increasing the air temperature. The very first with the help of the heat produced by the engine, and the other with the help of a liquid refrigerant . Your ventilation is all of the circuits and systems that will allow air to enter the passenger compartment. The main element will be the kicker which emits air inside your cabin. If there is little or no air, this is most likely a ventilation problem. We will discover in this post how a ventilation works, so as to better perceive the concerns and understand the technique to resolve it.ventilation-problem-Toyota-Rav-4- (2nd-Generation)

How a ventilation works on a Toyota Rav 4 (2nd Generation)

Ventilation is primarily used to regenerate the air inside the passenger compartment of this Toyota Rav 4 (2nd Generation). For the blower, it is often composed 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 button in the vehicle, the resistance is lowered.

Toyota Rav 4 (2nd Generation): common ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air arrives inside the passenger compartment of this Toyota Rav 4 (2nd Generation), it is likely that the air shutters are clogged. Thanks to a screwdriver flat, it is possible to remove the covers from the air vents. It is only necessary to check inside if these are blocked. When this is the case it is possible to clean them, as well as the shutters.

Dirty cabin filter

In the event that you perceive fumes and that your ventilation is weak, the problem probably comes from the cabin filter of this Toyota Rav 4 (2nd Generation). The latter is blocked and piled up bacteria with the years. It is quite common that it is dirty, it is there to filter the air that reaches us. There is no manufacturer's recommendation as to when to change it. It is only advisable to remove it, check its condition. In case it is really dirty, it will have to be changed.

Resistance of the blower HS

If the ventilation buttons on the Toyota Rav 4 (2nd Generation) do not work well, or really do not, it is probably related to the resistance. This resistance used to increase the voltage in order to increase the speed of the turbine. An inconsistent dysfunction of your ventilation is probably linked to a resistance problem. This little microchip is complex to troubleshoot. It must be changed.

HS blower motor

There are two fairly recurring concerns on the kicker. The brushes are damaged. Over time, they will wear out and cause false contact. The kicker may run randomly or even stop working at all. It also happens that the problem comes from bearings of the motor. In the event that the ventilation produces a hissing sound, comparable to a rusty mechanism, it is possible that its bearings lack lubrication.
