Let's not confuse the air conditioning , heating and ventilation of the Toyota Hilux. Heating and air conditioning are mechanisms that will reduce or increase the temperature. The very first thanks to the heat produced by the engine block, and the second with a fluid refrigerant . Your ventilation is the totality of channels and mechanisms that allow air to enter the passenger compartment. The main element is the kicker which emits air into your vehicle. If the air hardly or hardly ever reaches the air, this is probably a ventilation malfunction. We will see through this file how ventilation works, so as to better perceive the malfunctions and understand how to remedy them.
How a ventilation works on a Toyota Hilux
The ventilation is used first to circulate the air in the interior of the Toyota Hilux. As for the pulser, it usually consists of a resistor, a turbine, and a motor. The lower the integral resistance of the circuit, the faster the turbine runs. By rotating the switch in the vehicle, the resistance is thus reduced.
Toyota Hilux: regular ventilation problems
Dirty air ducts
If the ventilation works but very little air enters the interior of the Toyota Hilux, it is possible that your air shutters are blocked. Thanks to a screwdriver flat, you can remove the air flap valves. It will suffice to check inside if these are blocked. If this is what happens you can scour them, but also the valves.
Dirty cabin filter
When you perceive effluxes and this ventilation lacks intensity, the malfunction probably comes from the cabin filter of the Toyota Hilux. It clogs up and collects bacteria with time. It is quite normal that it is clogged, it serves to clarify the air that reaches you. There is no instruction from the manufacturer as to when to replace it. We advise you stupidly to remove it, check its condition. In case it is completely dirty, it will be better to replace it.
Resistance of the blower HS
If the ventilation buttons on your Toyota Hilux do not work well, or even not at all, it is probably due to the resistance. This resistance allows to raise the voltage to be able to increase the speed of the turbine. Inconsistent operation of this ventilation is probably due to a resistance malfunction. This little microchip is difficult to repair. It will have to be replaced.
HS blower motor
There are two fairly recurring malfunctions concerning the blower. The brushes may be worn out. Over the years, the latter will be able to wear out and generate false contact. The fan may run randomly or even stop working at all. It also happens that the dysfunction comes from bearings of the fan motor. In the event that the ventilation produces a hissing sound, comparable to a rusty mechanical, it happens that its bearings lack lubrication. We invite you to comment on this file if your dysfunction is different in order to help Internet users. Good walk!
