Let's not confuse the air conditioning , heating and ventilation of the Kia Rocsta. Heating and cooling are found to be systems that reduce or increase the air temperature. The very first thanks to the heat produced by the engine, and the other using a fluid refrigerant . Ventilation is the totality of channels and devices that will allow air to reach the interior. The essential element will be kicker which emits air into your vehicle. If there is little or no air supply, it is probably a malfunction of ventilation. We will see in this file how a ventilation works, in order to better identify the concerns and understand how to resolve it.
How ventilation works on a Kia Rocsta
Ventilation is primarily used to circulate the air in the interior of the Kia Rocsta. For the blower, it is generally composed of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By turning the button in the vehicle, the resistance is therefore lowered.
Kia Rocsta: usual ventilation problems
Dirty air ducts
When the ventilation turns but a small amount of air enters the interior of the Kia Rocsta, it is possible that your air shutters are blocked. With the aid of screwdriver flat, it is possible to remove the covers from the air vents. It will suffice to look inside if they are obstructed. If this is what is happening it is possible to scour them, but also the valves.
Dirty cabin filter
If you feel effluxes and the ventilation lacks power, the malfunction must probably come from the cabin filter of the Kia Rocsta. It gets dirty and accumulates bacteria with the years. It is really normal that it is dirty, it serves to clarify the air that reaches us. There is no manufacturer's recommendation as to when to change it. We simply advise you to remove it, check its condition. When the latter is particularly dirty, it will be necessary to change it.
Resistance of the blower HS
When the ventilation controls on your Kia Rocsta malfunction, if at all, it is probably related to resistance. The resistance allows to raise the voltage in order to increase the speed of the turbine. A strange functioning of the ventilation is probably linked to a resistance malfunction. This electronic chip is complicated to repair. We will have to change it.
HS blower motor
There are two fairly regular concerns about the kicker. The brushes may be damaged. Over the years, these can be damaged and generate false contact. Your kicker could spin randomly, and even not work at all. It also happens that the dysfunction comes from bearings of the fan motor. When the ventilation makes a sharp noise, comparable to a rusty mechanism, its bearings may lack lubrication. Do not hesitate to comment on this file when your dysfunction is different in order to help other readers. See you soon!
