Let's not confuse the air conditioning , heating and ventilation in your Toyota Corolla 9. Heating and air conditioning are systems that reduce or increase the air temperature. The very first through the heat generated from the engine block, and the other using a fluid refrigerant . Ventilation is all the circuits and systems that allow air to reach the interior. The fundamental element is the kicker which propels the air inside your cabin. If there is little or no air supply, it is probably a ventilation problem. We will see in this article how a ventilation works, to be able to better identify the problems and understand by what means to solve it.
How a ventilation works on a Toyota Corolla 9
Ventilation is primarily used to regenerate the air inside the interior of your Toyota Corolla 9. For the blower, the latter is generally made of a resistance, 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 passenger compartment, the resistance is reduced.
Toyota Corolla 9: usual ventilation problems
Dirty air ducts
If the ventilation turns but little air reaches the interior of your Toyota Corolla 9, it is conceivable that the air flaps are obstructed. Thanks to a screwdriver flat, do not hesitate to remove the valves from the air vents. It is only necessary to look inside if they are blocked. If ever, do not hesitate to clean them, as well as the valves.
Dirty cabin filter
If you discern effluxes and that this ventilation is weak, the problem probably comes from the cabin filter of your Toyota Corolla 9. It clogs and accumulates bacteria as time goes by. It is completely normal that this one is clogged, it is used to purify the air which reaches us. There is no manufacturer's instruction on when to change it. It is advisable just to remove it, check its condition. If the latter is particularly black, it will need to be replaced.
Resistance of the blower HS
If the ventilation setting on your Toyota Corolla 9 malfunctions, if at all, it is probably due to the resistance. The resistance is used to increase the voltage to increase the speed of the turbine. An inconsistent dysfunction of this ventilation is undoubtedly linked to a resistance problem. This microchip is difficult to troubleshoot. It will have to be replaced.
HS blower motor
There are two relatively recurring problems with the kicker. The brushes are damaged. The more time passes, they can be damaged and produce false contact. Your kicker may work randomly, or not work at all. It is also possible that the problem comes from bearings of the fan motor. If the ventilation whistles, like a rusty mechanic, it is possible that its bearings lack lubrication.
