Let's not confuse the air conditioning , heating and ventilation from your seat leon. Heating and air conditioning are devices that can reduce or increase the air temperature. The first through the heat produced by the engine block, and the second using a fluid refrigerant . The famous ventilation is the set of channels and mechanisms that allow air to reach the interior. The essential component is kicker which propels the air into your vehicle. If the air never arrives very little or not at all, it is undoubtedly a concern of ventilation. We will discover in this file how a ventilation works, in order to better identify the concerns and understand how to remedy them.
How does ventilation work on a seat leon
Ventilation first of all serves to regenerate the air inside the passenger compartment of your seat leon. As for the blower, the latter generally consists of a resistor, a turbine, and a motor. The lower the total resistance of the electrical system, the faster the turbine operates. By turning the switch in the passenger compartment, the resistance is thus reduced.
seat leon: regular ventilation problems
Dirty air ducts
If the ventilation works but a small amount of air arrives in the interior of your seat leon, it is likely that your air shutters are clogged. Using a screwdriver flat, do not hesitate to disassemble the air shutter covers. It will be enough to take a look inside if they are blocked. If this is what is happening, do not hesitate to dust them, as well as the shutters.
Dirty cabin filter
In case you smell odors and the ventilation lacks power, the problem probably comes from the cabin filter of your seat leon. It clogs and piles up bacteria as time goes by. It remains completely common that it is dirty, it is there to purify the air that reaches us. There is no manufacturer's instruction as to when to change it. We advise you simply to remove it, look at its condition. If it is particularly black, it will be necessary to change it.
Resistance of the blower HS
If the ventilation buttons on your seat leon are not working well, or even really not, it is probably related to resistance. This resistance allows to increase the voltage to be able to increase the speed of this turbine. A bizarre ventilation malfunction may be related to a concern for resistance. This microchip is complicated to troubleshoot. It will have to be changed.
HS blower motor
There are two fairly recurring concerns about the kicker. The brushes are deteriorated. The more time passes, they can be damaged and generate electrical faults. Your kicker could work very randomly, and might not even work at all. It is also possible that the concern comes from bearings of the motor. If the ventilation produces a hissing sound, like a rusty mechanism, it can happen that the bearings lack lubrication.
