Let's not confuse the air conditioning , heating and ventilation of the Kia Sorento 3. Heating and air conditioning are devices that can lower or increase the temperature. The first by means of the heat produced by the engine block, and the second with the help of a liquid refrigerant . Your ventilation is all of the circuits and systems that allow air to enter the passenger compartment. The fundamental component will be kicker which propels the air within your automobile. If there is barely or no air at all, it is probably a ventilation problem. We will see within this file how a ventilation works, in order to better identify the problems and understand by what means to resolve it.
How ventilation works on a Kia Sorento 3
The ventilation is primarily used to regenerate the air inside the cabin of the Kia Sorento 3. Regarding the blower, the latter is generally made of a resistance, a turbine, and a motor. The lower the total resistance of the circuit, the faster the turbine turns. By turning the button in the passenger compartment, the resistance is lowered.
Kia Sorento 3: usual ventilation problems
Dirty air ducts
If the ventilation works but little air reaches the interior of the Kia Sorento 3, it is likely that the air shutters are blocked. Thanks to a screwdriver flat, you can remove the valves from the air vents. You just have to check inside if they are blocked. When this is happening you can clean them, as well as the valves.
Dirty cabin filter
When you discern odors and this ventilation is weak, the problem probably comes from the cabin filter of the Kia Sorento 3. It becomes blocked and accumulates bacteria with time. It is quite common that it is dirty, it serves to clarify the air that reaches you. There is no manufacturer's instruction as to when to change it. It is only advisable to dismantle it, check its condition. In the event that it is completely dirty, it will be necessary to replace it.
Resistance of the blower HS
If the ventilation controls of the Kia Sorento 3 do not work well, if at all, it is probably related to the resistance. This resistance allows to raise the voltage to increase the speed of this turbine. A strange functioning of this ventilation can be due to a resistance problem. This microchip is complex to troubleshoot. You will have to replace it.
HS blower motor
There are two relatively recurring problems with the kicker. The brushes may be damaged. Over time, they may deteriorate and cause electrical faults. Your fan may spin randomly or even not work at all. It is also possible that the problem stems from bearings of the motor. If the ventilation produces a hissing sound, comparable to a rusty mechanical, it happens that the bearings lack lubrication.
