Do not confuse the air conditioning , heating and ventilation of the Toyota Crown. Heating and air conditioning are devices that give the possibility of lowering or increasing the air temperature. The very first with the help of the heat generated from the engine, and the second with the help of a fluid refrigerant . Ventilation is the totality of channels and mechanisms that allow air to reach the interior. The main component is kicker which emits air into your vehicle. If there is little or no air supply, it is probably a malfunction of ventilation. We will see within this text how a breakdown works, in order to better identify the problems and understand how to resolve it.
How a ventilation works on a Toyota Crown
Ventilation is primarily used to regenerate the air inside the interior of the Toyota Crown. Regarding the blower, the latter is usually composed of a resistor, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine operates. By turning the knob in the passenger compartment, the resistance is thus reduced.
Toyota Crown: usual ventilation problems
Dirty air ducts
If the ventilation works but very little air arrives in the interior of the Toyota Crown, it is likely that the air shutters are blocked. Using a screwdriver flat, do not hesitate to disassemble the air shutter covers. You just have to check in if they are congested. If this is what happens, don't hesitate to dust them, but also the shutters.
Dirty cabin filter
When you see fumes and the ventilation is poor, the malfunction is probably due to the cabin filter of the Toyota Crown. It clogs and piles up bacteria with the years. It remains completely common that it is dirty, it is there to clarify the air that reaches you. There is no manufacturer's instruction on when to change it. We simply advise you to disassemble it, check its condition. If it is really dirty, it is better to replace it.
Resistance of the blower HS
If the ventilation setting of your Toyota Crown does not work well, if at all, it is probably related to the resistance. This resistance increases the voltage to increase the speed of the turbine. A strange malfunction of ventilation is probably linked to a resistance malfunction. This electronic chip is complex to repair. It will have to be replaced.
HS blower motor
There are two fairly regular problems with the kicker. The brushes are damaged. Over time, these can be damaged and produce electrical faults. The fan may spin randomly, or not work at all. The malfunction may also be caused by bearings of the fan motor. If the ventilation hisses, like a rusty mechanic, it is possible that its bearings require lubrication.
