Do not confuse the air conditioning , heating and ventilation of this Kia Carnival. Heating and air conditioning are systems that reduce or increase the temperature. The very first by means of the heat emitted from the engine, and the second with the help of a fluid refrigerant . Ventilation is the totality of the circuits and devices that give the possibility of air reaching the passenger compartment. The fundamental element is the kicker which emits air inside your cabin. If there is little or no air supply, it is probably a ventilation problem. We will see through this guide how a ventilation works, in order to better perceive the problems and understand the technique to solve it.
How ventilation works on a Kia Carnival
The ventilation is primarily used to regenerate the air inside the cabin of this Kia Carnival. For the blower, it often consists of a resistor, a turbine, and a motor. The more the total resistance of the circuit is reduced, the faster the turbine operates. By turning the switch in the passenger compartment, the resistance is therefore reduced.
Kia Carnival: frequent ventilation problems
Dirty air ducts
If the ventilation turns but very little air reaches the interior of this Kia Carnival, it is plausible that your air shutters are blocked. Thanks to a screwdriver flat, it is possible to remove the covers of the air vents. It will suffice to check inside if these are blocked. When this is the case, it is possible to dust them, but also the valves.
Dirty cabin filter
If you ever discern odors and this ventilation lacks intensity, the concern probably comes from the cabin filter of this Kia Carnival. The latter clogs and piles up bacteria with the years. It's really normal that it is dirty, it is there to filter the air that reaches you. There is no manufacturer's recommendation as to when to change it. We only advise you to remove it, check its condition. In case it is particularly black, it will be necessary to replace it.
Resistance of the blower HS
If the ventilation settings of the Kia Carnival do not work well, or really do not, it is probably linked to the resistance. This resistance is used to increase the voltage in order to increase the speed of the turbine. A strange malfunction of this ventilation is probably linked to a concern for resistance. This little microchip is difficult to repair. It needs to be replaced.
HS blower motor
There are several relatively recurring problems with the kicker. The brushes are deteriorated. As time goes by, they can wear out and cause false contact. Your fan may spin randomly, and may not even spin at all. It also happens that the concern comes from bearings of the motor. In the event that the ventilation produces a hissing sound, such as a rusty mechanism, it happens that the bearings require lubrication. We invite you to comment on this guide in case your concern is different in order to help our readers. Good walk!
