Let's not confuse the air conditioning , heating and ventilation of this Toyota Rav 4 (3rd Generation). Heating and air conditioning happen to be systems that can help reduce or boost the air temperature. The first thanks to the heat generated by the engine, and the other with the help of a fluid refrigerant . The famous ventilation is all the channels and mechanisms that give the air the opportunity to reach inside. The fundamental element is the kicker which emits the air within your cabin. If ever little or no air is coming in, it is probably a ventilation malfunction. We will discover in this article how a ventilation works, in order to better perceive the problems and assimilate by which means to solve them.ventilation-problem-Toyota-Rav-4- (3nd-Generation)

How a ventilation works on a Toyota Rav 4 (3nd Generation)

The ventilation is primarily used to circulate the air inside the passenger compartment of this Toyota Rav 4 (3rd Generation). As for the blower, the latter generally consists of a resistance, a turbine and a motor. The more the integral resistance of the circuit is lowered, the faster the turbine operates. By turning the knob in the vehicle, the resistance is lowered.

Toyota Rav 4 (3th Generation): usual ventilation problems

Dirty air ducts

When the ventilation turns but very little air enters the cabin of this Toyota Rav 4 (3rd Generation), it is conceivable that your air flaps are blocked. Using a screwdriver flat, you can remove the covers from the air vents. It is only necessary to take a look inside if these are blocked. If this is the case you can clean them, but also the valves.

Dirty cabin filter

When you perceive odors and the ventilation lacks intensity, the problem is probably due to the cabin filter of this Toyota Rav 4 (3rd Generation). It gets dirty and accumulates bacteria as time goes by. It is completely normal that it is clogged, it serves to clarify the air which reaches you. There is no recommendation from the manufacturer as to when to change it. We just advise you to take it apart and check its condition. When this is particularly black, it will need to be replaced.

Resistance of the blower HS

When the ventilation controls on your Toyota Rav 4 (3rd Generation) aren't working well, or even really not, it is probably related to resistance. The resistance is used to raise the voltage to amplify the speed of the turbine. Strange ventilation may be related to resistance malfunction. This electronic chip is complex to repair. It needs to be replaced.

HS blower motor

There are two fairly regular issues with the kicker. The brushes are damaged. The more time passes, the latter will be able to deteriorate and produce electrical faults. The fan may run haphazardly or not run at all. It also happens that the malfunction comes from bearings of the motor. When the ventilation whistles, comparable to rusty mechanics, the bearings may lack lubrication. We invite you to comment on this article when your dysfunction is different to help Internet users.
