Do not confuse the air conditioning , heating and ventilation of this Seat 133. Heating and air conditioning are systems that offer the possibility of lowering or increasing the temperature. The first with the help of heat generated from the engine, and the other with the help of a liquid refrigerant . The famous ventilation is the set of channels and devices that will allow air to reach the interior of the vehicle. The fundamental element is the kicker which sends air into your automobile. If there is little or no air, this is most likely a ventilation problem. Thanks to this text, we will see how ventilation works, so that we can better identify problems and understand how to remedy them.ventilation-problem-Seat-133

How ventilation works on a Seat 133

The ventilation is primarily used to circulate the air inside the passenger compartment of this Seat 133. Regarding the blower, the latter is often composed of a resistance, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine runs. By rotating the switch in the vehicle, the resistance is reduced.

Seat 133: frequent ventilation problems

Dirty air ducts

If ventilation never works but little air arrives inside the passenger compartment of this Seat 133, it is conceivable that these air flaps are obstructed. Using a screwdriver flat, do not hesitate to remove the covers from the air vents. You just have to look inside if they are blocked. If this is what is happening, do not hesitate to dust them, but also the shutters.

Dirty cabin filter

When you perceive fumes and your ventilation lacks intensity, the problem probably comes from the cabin filter of this Seat 133. It becomes blocked and accumulates bacteria as time goes by. It is completely normal that it is dirty, it is used to filter the air that reaches you. There is no manufacturer's instruction as to when to change it. It is advisable just to remove it, look at its condition. If it is particularly black, it will be necessary to replace it.

Resistance of the blower HS

If the ventilation setting on your Seat 133 ever works poorly, or even not at all, it is probably due to the resistance. The resistance is used to increase the voltage in order to increase the speed of the turbine. A suspicious functioning of your ventilation is probably linked to a resistance problem. This little microchip is complex to troubleshoot. You will have to replace it.

HS blower motor

There are several fairly regular problems with the kicker. The brushes may be worn out. Over the years, the latter may be damaged and generate false contact. Your kicker may spin randomly, or not work at all. The problem may also arise from bearings of the motor. If the ventilation whistles, like a rusty mechanic, it is possible that the bearings lack lubrication.
