Let's not confuse the air conditioning , heating and ventilation of your Lancia Aurelia. Heating and cooling are mechanisms that will reduce or increase the temperature of the air. The very first with the help of the heat generated from the engine block, and the other with the help of a fluid refrigerant . Your ventilation is all of the channels and devices that allow air to get inside. The fundamental component is the kicker which propels the air inside your cabin. In the event that the air arrives very little or not at all, it is undoubtedly a malfunction of ventilation. We will discover in this guide how a ventilation works, in order to better discern the problems and understand how to solve it.ventilation-problem-Lancia-Aurelia

How does ventilation work on a Lancia Aurelia

First of all, ventilation is used to circulate the air in the interior of your Lancia Aurelia. For the blower, the latter generally consists of a resistor, a turbine, and a motor. The more the integral resistance of the circuit is lowered, the faster the turbine runs. By turning the switch in the passenger compartment, the resistance is lowered.

Lancia Aurelia: regular ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air arrives inside the cabin of your Lancia Aurelia, it is likely that your air shutters are obstructed. With the aid of screwdriver flat, you can remove the valves from the air vents. You just have to take a look in if they are crowded. If this is what is happening you can clean them, but also the valves.

Dirty cabin filter

In case you perceive fumes and your ventilation lacks power, the malfunction certainly comes from the cabin filter of your Lancia Aurelia. The latter becomes blocked and accumulates bacteria as time goes by. It is quite normal that it is dirty, it is used to purify the air that reaches us. There is no manufacturer's recommendation as to when to change it. We simply advise you to dismantle it, look at its condition. If the latter is completely dirty, it will be necessary to replace it.

Resistance of the blower HS

If the Lancia Aurelia's ventilation controls are not working well, or even not at all, it is certainly linked to resistance. This resistance allows to raise the voltage to be able to amplify the speed of this turbine. A bizarre malfunction of your ventilation is probably linked to a resistance malfunction. This microchip is difficult to troubleshoot. It must be replaced.

HS blower motor

There are two relatively regular problems with the kicker. The brushes may be damaged. Over time, they may deteriorate and produce false contact. Your kicker could spin very randomly, and even not spin at all. It also happens that the dysfunction comes from bearings of the motor. In the event that the ventilation produces a hissing sound, comparable to a rusty mechanism, its bearings may lack lubrication. Do not hesitate to comment on this guide if your dysfunction is different in order to help Internet users. Good road!
