Do not confuse the air conditioning , heating and ventilation of your Kia Optima 2 Sw. Heating and air conditioning happen to be systems which give the possibility of decreasing or increasing the temperature. The first with the help of the heat produced by the engine, and the second with the help of a fluid refrigerant . Your ventilation is all the ducts and devices that allow the air to reach the interior of the vehicle. The fundamental component will be the kicker that emits air into your vehicle. In the event that little or no air is supplied, it is certainly a ventilation malfunction. In this post, we will discover how ventilation works, in order to better identify the problems and understand how to remedy them.problem-ventilation-Kia-Optima-2-Sw

How does ventilation work on a Kia Optima 2 Sw

Ventilation is primarily used to regenerate the air in the passenger compartment of your Kia Optima 2 Sw. For the blower, the latter generally consists of a resistance, a turbine, and an engine. The more the integral resistance of the electrical system is reduced, the faster the turbine rotates. By rotating the switch in the vehicle, resistance is reduced.

Kia Optima 2 Sw: usual ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air is entering the passenger compartment of your Kia Optima 2 Sw, the air flaps are likely to be blocked. With the aid of screwdriver flat, do not hesitate to remove the covers of the air flaps. It will suffice to look in if these are obstructed. When this is the case, do not hesitate to clean them, but also the shutters.

Dirty cabin filter

When you perceive odors and the ventilation is lacking in intensity, the problem is undoubtedly the cabin filter of your Kia Optima 2 Sw. bacteria with the years. It is completely normal that it is clogged, it is there to filter the air which reaches you. There is no recommendation from the manufacturer for when to replace it. We advise you to simply remove it, look at its condition. If the latter is particularly dirty, it will be preferable to replace it.

Resistance of the blower HS

If the buttons for the ventilation of your Kia Optima 2 Sw are working badly, or really not, it is probably due to the resistance. This resistance is used to increase the voltage to increase the speed of the turbine. Shady ventilation malfunction is likely related to resistance malfunction. This small electronic chip is complex to repair. It is necessary to replace it.

HS blower motor

There are several fairly regular issues with the kicker. The brushes may be damaged. The more time passes, they can deteriorate and cause electrical faults. The kicker could spin very randomly, or even not spin at all. It also happens that the dysfunction comes from bearings of the motor. If the ventilation produces a hissing sound, comparable to rusty mechanics, it happens that its bearings are lacking in lubrication. We invite you to comment on this post when your dysfunction is different in order to help our readers. See you soon!
