Do not confuse the air conditioning , heating and ventilation of your Toyota Highlander. Heating and air conditioning are mechanisms that offer the possibility of reducing or increasing the temperature. The first through the heat emitted by the engine block, and the other with a fluid refrigerant . The famous ventilation is the totality of channels and mechanisms that give the opportunity for air to reach the interior of the vehicle. The main component is kicker which propels the air within your vehicle. If there is little or no air supply, it is probably a malfunction of ventilation. We will see in this article how a ventilation works, in order to better identify the concerns and assimilate how to solve it.ventilation-problem-Toyota-Highlander

How a ventilation works on a Toyota Highlander

The ventilation is primarily used to circulate the air in the interior of your Toyota Highlander. Regarding the blower, it often consists of a resistor, a turbine, and a motor. The more the total resistance of the circuit is reduced, the faster the turbine operates. By turning the knob in the vehicle, the resistance is reduced.

Toyota Highlander: common ventilation issues

Dirty air ducts

If the ventilation works but very little air arrives in the interior of your Toyota Highlander, it is possible that these air flaps are clogged. With the aid of screwdriver flat, you can remove the air flap valves. It is only necessary to check inside if these are blocked. When this is the case you can clean them, but also the valves.

Dirty cabin filter

When you smell odors and the ventilation lacks power, the malfunction probably comes from the cabin filter of your Toyota Highlander. It becomes blocked and accumulates bacteria with time. It is quite common that it is dirty, it is there to filter the air that reaches you. There is no manufacturer's instruction as to when to change it. We just advise you to remove it, look at its condition. If it is particularly black, it will be better to change it.

Resistance of the blower HS

If the ventilation buttons on your Toyota Highlander malfunction, or even really do not, it is probably due to the resistance. This resistance used to raise the voltage to increase the speed of the turbine. A bizarre ventilation malfunction is probably related to a resistance malfunction. This small electronic chip is complex to repair. You will have to change it.

HS blower motor

There are several relatively regular concerns about the kicker. The brushes may be damaged. As time goes by, they can deteriorate and cause electrical faults. Your fan may run randomly, or may not work at all. It also happens that the dysfunction comes from bearings of the motor. If the ventilation makes a sharp noise, such as a rusty mechanism, its bearings may lack lubrication. Feel free to comment on this article in case your dysfunction is different to help our readers. Good road!
