Do not confuse the air conditioning , heating and ventilation of this Toyota Land Cruiser Serie 90. Heating and air conditioning are devices that give the possibility of reducing or increasing the temperature. The very first through the heat emitted by the engine block, and the second with the help of a liquid refrigerant . Your ventilation is the entirety of the channels and systems that give the possibility of air to enter the passenger compartment. The main element is the kicker which sends air into your cabin. If there is very little or no air supply, it is probably a ventilation problem. We will find out from this text how ventilation works, in order to better identify problems and understand how to solve them.
How a ventilation works on a Toyota Land Cruiser Serie 90
The ventilation is used first to circulate the air inside the passenger compartment of this Toyota Land Cruiser Serie 90. As for the blower, this usually consists of a resistance, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine operates. By rotating the switch in the passenger compartment, the resistance is therefore reduced.
Toyota Land Cruiser Serie 90: usual ventilation problems
Dirty air ducts
When the ventilation turns but a small amount of air enters the interior of this Toyota Land Cruiser Serie 90, it is plausible that your air shutters are blocked. Thanks to a screwdriver flat, do not hesitate to disassemble the air shutter covers. It is only necessary to look inside if these are blocked. If this is the case, do not hesitate to scour them, as well as the shutters.
Dirty cabin filter
If you ever perceive fumes and that this ventilation is weak, the concern comes undoubtedly from the cabin filter of this Toyota Land Cruiser Serie 90. This one becomes blocked and accumulates bacteria with the years. It is completely normal that this one is dirty, it is there to clarify the air which reaches you. There is no manufacturer's recommendation as to when to replace it. We only advise you to remove it, check its condition. When it is really dirty, it will need to be replaced.
Resistance of the blower HS
When the ventilation buttons on the Toyota Land Cruiser Serie 90 do not work well, or not at all, it is probably linked to the resistance. This resistance is used to increase the voltage to increase the speed of this turbine. A shady operation of this ventilation may be due to a concern for resistance. This microchip is complicated to troubleshoot. It must be replaced.
HS blower motor
There are two fairly common problems with the kicker. The brushes are worn. The more time passes, they will be able to wear out and generate electrical faults. The kicker could operate randomly, and even not rotate at all. The concern may also arise from bearings of the fan motor. When the ventilation makes a sharp noise, comparable to a rusty mechanism, its bearings may lack lubrication.
