Do not confuse the air conditioning , heating and ventilation of this Toyota 4runner. Heating and air conditioning are mechanisms that reduce or increase the temperature. The first through the heat generated by the engine block, and the second with a liquid refrigerant . Ventilation is all of the ducts and systems that will allow air to enter the passenger compartment. The main element is the kicker which sends air into your cabin. In the event that the air arrives very little or not at all, it is certainly a problem of ventilation. We will discover within this text how a breakdown works, so as to better identify the concerns and understand the technique to remedy them.ventilation-problem-Toyota-4runner

How a ventilation works on a Toyota 4runner

Ventilation first of all serves to regenerate the air in the passenger compartment of this Toyota 4runner. Regarding the blower, it is generally made of a resistor, a turbine, and a motor. The lower the integral resistance of the circuit, the faster the turbine turns. By rotating the button in the vehicle, the resistance is therefore reduced.

Toyota 4runner: common ventilation issues

Dirty air ducts

If the ventilation turns but a small amount of air arrives inside the passenger compartment of this Toyota 4runner, it is likely that these air shutters are clogged. Thanks to a screwdriver flat, do not hesitate to remove the covers from the air vents. You just have to look inside if they are clogged. When this is happening do not hesitate to clean them, as well as the valves.

Dirty cabin filter

When you discern effluxes and your ventilation is poor, the problem certainly comes from the cabin filter of this Toyota 4runner. The latter clogs and piles up bacteria as time goes by. It is completely normal that it is clogged, it is used to purify the air which reaches you. There is no manufacturer's recommendation as to when to replace it. We simply advise you to remove it, check its condition. If it is completely dirty, it will be better to replace it.

Resistance of the blower HS

If the Toyota 4runner's ventilation controls ever work poorly, or even not at all, it's certainly related to the resistance. The resistance increases the voltage to be able to increase the speed of this turbine. A strange functioning of your ventilation can be linked to a resistance problem. This little microchip is difficult to repair. It needs to be replaced.

HS blower motor

We can find several fairly regular concerns about the kicker. The brushes are worn. Over time, they will be able to deteriorate and produce false contact. The kicker may run randomly, or not activate at all. In addition, the problem may arise from bearings of the fan motor. If the ventilation makes a sharp noise, comparable to a rusty mechanism, it happens that its bearings require lubrication.
