Do not confuse the air conditioning , heating and ventilation of the Toyota Land Cruiser Serie 70. Heating and air conditioning are systems that lower or increase the air temperature. The first thanks to the heat produced by the engine, and the second with a fluid refrigerant . The famous ventilation is all the circuits and systems that give the possibility of air to reach the interior of the vehicle. The essential component is kicker which propels the air within your vehicle. If the air comes in little or not at all, it is probably a malfunction of ventilation. We will see through this guide how ventilation works, in order to better identify the problems and assimilate the technique to solve it.ventilation-problem-Toyota-Land-Cruiser-Serie-70

How a ventilation works on a Toyota Land Cruiser Serie 70

The ventilation is used to start circulating the air inside the interior of the Toyota Land Cruiser Serie 70. As for the blower, the latter is usually made of a resistance, a turbine, and a motor. The more the total resistance of the circuit is reduced, the faster the turbine runs. By turning the button in the vehicle, the resistance is lowered.

Toyota Land Cruiser Serie 70: regular ventilation problems

Dirty air ducts

When the ventilation turns but little air arrives inside the passenger compartment of the Toyota Land Cruiser Serie 70, it is conceivable that the air shutters are blocked. Using a screwdriver flat, you can disassemble the air shutter covers. It will suffice to check inside if these are obstructed. If this is what is happening you can clean them, but also the shutters.

Dirty cabin filter

If you smell fumes and this ventilation is weak, the malfunction certainly comes from the cabin filter of the Toyota Land Cruiser Serie 70. It becomes blocked and accumulates bacteria as time goes by. It is quite common that it is dirty, it is used to filter the air that reaches us. There is no recommendation from the manufacturer as to when to change it. We only advise you to disassemble it, look at its condition. When the latter is completely black, it will be better to change it.

Resistance of the blower HS

When the ventilation buttons on your Toyota Land Cruiser Serie 70 are not working well, or even really not, it is certainly due to the resistance. The resistance used to increase the voltage to increase the speed of the turbine. A bizarre functioning of this ventilation is probably linked to a resistance malfunction. This electronic chip is complicated to repair. It is necessary to change it.

HS blower motor

There are two fairly regular problems with the kicker. The brushes may be damaged. Over the years, they can be damaged and cause electrical faults. Your kicker could spin randomly, or even not spin at all. It is also possible that the malfunction comes from bearings of the motor. When the ventilation makes a sharp noise, comparable to a rusty mechanical, it is possible that the bearings lack lubrication.
