Let's not confuse the air conditioning , heating and ventilation of your Toyota Rav 4 (4th Generation). Heating and air conditioning are mechanisms that decrease or increase the air temperature. The very first through the heat emitted from the engine, and the second with the help of a liquid refrigerant . Your ventilation is all of the ducts and systems that allow air to enter the vehicle. The fundamental component will be kicker which sends air into your vehicle. If there is little or no air supply, it is probably a ventilation problem. We will see in this guide how ventilation works, in order to better discern the problems and understand how to solve it.ventilation-problem-Toyota-Rav-4- (4nd-Generation)

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

The ventilation is used first to regenerate the air inside the passenger compartment of your Toyota Rav 4 (4th Generation). Regarding the blower, it generally consists of a resistor, a turbine, and a motor. The more the integral resistance of the circuit is reduced, the faster the turbine operates. By turning the button in the vehicle, the resistance is reduced.

Toyota Rav 4 (4th Generation): usual ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air arrives inside the cabin of your Toyota Rav 4 (4th Generation), it is possible that the air shutters are obstructed. Using a screwdriver flat, it is possible to remove the covers of the air shutters. It is only necessary to check inside if these are blocked. When this is the case it is possible to scour them, but also the shutters.

Dirty cabin filter

When you feel fumes and this ventilation is weak, the concern is certainly from the cabin filter of your Toyota Rav 4 (4th Generation). The latter clogs and accumulates bacteria with time. It is really normal that this one is dirty, it is there to purify the air which arrives at you. There is no manufacturer's instruction on when to change it. We only advise you to remove it, look at its condition. If the latter is completely dirty, it will be necessary to replace it.

Resistance of the blower HS

If the ventilation controls on your Toyota Rav 4 (4th Generation) are not working well, or not at all, it is certainly related to the resistance. This resistance is used to increase the voltage in order to increase the speed of the turbine. Inconsistent operation of this ventilation is probably linked to a concern for resistance. This little microchip is difficult to repair. It must be replaced.

HS blower motor

There are several fairly common problems with the kicker. The brushes may be damaged. The more time passes, the latter will be able to be damaged and cause false contact. Your fan may run very randomly, or may not spin at all. It is also possible that the concern comes from bearings of the fan motor. If the ventilation makes a sharp noise, such as a rusty mechanic, the bearings may require lubrication.
