Let's not confuse the air conditioning , heating and ventilation from the seat altea. Heating and air conditioning are devices that decrease or increase the air temperature. The very first by means of the heat generated by the engine, and the second with the help of a fluid refrigerant . Your ventilation is all of the circuits and mechanisms that will allow air to enter the passenger compartment. The main component is kicker which sends air into your cabin. If there is hardly any air at all, it is probably a ventilation problem. We will see thanks to this file how a ventilation works, to be able to better identify the problems and apprehend by what means to solve it.problem-ventilation-seat-altea

How ventilation works on a seat altea

The ventilation is used first to circulate the air in the passenger compartment of the seat altea. For the blower, the latter is usually composed of a resistor, a turbine, and a motor. The more the integral resistance of the electrical system is lowered, the faster the turbine operates. By turning the button in the passenger compartment, the resistance is therefore reduced.

seat altea: regular ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air enters the passenger compartment of the seat altea, it is likely that the air shutters are clogged. Thanks to a screwdriver flat, it is possible to remove the valves from the air vents. It will suffice to check inside if these are blocked. If this is what is happening it is possible to scour them, as well as the shutters.

Dirty cabin filter

If you can see fumes and ventilation is poor, the problem must most likely come from the cabin air filter of the seat altea. It becomes clogged and accumulates bacteria with time. It remains totally common that it is dirty, it is there to clarify the air that reaches you. There is no recommendation from the manufacturer as to when to replace it. It is advisable to simply remove it, check its condition. If it is really black, it will be better to replace it.

Resistance of the blower HS

If the ventilation buttons on the seat altea work poorly, or not at all, it is certainly linked to resistance. This resistance allows to increase the voltage to increase the speed of this turbine. A strange functioning of the ventilation is probably linked to a resistance problem. This little electronic chip is complicated to repair. It needs to be replaced.

HS blower motor

There are several relatively recurring problems with the kicker. The brushes are worn. Over the years, the latter may wear out and cause electrical faults. The fan may run very randomly, or may not work at all. It also happens that the problem stems from bearings of the motor. If the ventilation hisses, like a rusty mechanic, it can happen that its bearings lack lubrication.
