Let's not confuse the air conditioning , heating and ventilation of your Lancia Appia. Heating and air conditioning are devices that reduce or increase the temperature. The first by means of the heat produced by the engine, and the other with a liquid refrigerant . Ventilation is all the ducts and devices that give the opportunity for air to reach the interior. The essential component is kicker which sends air into your cabin. In the event that the air arrives very little or not at all, it is certainly a concern of ventilation. We will discover in this file how ventilation works, so as to better perceive dysfunctions and assimilate by what means to resolve it.
How does ventilation work on a Lancia Appia
Ventilation is primarily used to circulate the air in the interior of your Lancia Appia. As for the pulser, it is generally made of a resistor, a turbine, and a motor. The lower the total resistance of the electrical system, the faster the turbine turns. By turning the button in the vehicle, the resistance is reduced.
Lancia Appia: usual ventilation problems
Dirty air ducts
When the ventilation turns but little air arrives in the interior of your Lancia Appia, it is conceivable that your air shutters are obstructed. Using a screwdriver flat, do not hesitate to dismantle the valves of the air vents. It will suffice to check inside if these are obstructed. If this is what is happening, do not hesitate to dust them, as well as the shutters.
Dirty cabin filter
If you ever perceive effluxes and that the ventilation is weak, the concern certainly comes from the cabin filter of your Lancia Appia. It gets dirty and piles up bacteria as time goes by. It is completely common that it is dirty, it is used to filter the air that reaches us. There is no manufacturer's recommendation as to when to replace it. We only advise you to disassemble it, check its condition. When it is completely dirty, it will need to be replaced.
Resistance of the blower HS
When the Lancia Appia's ventilation controls aren't working well, or even really not, it's definitely related to resistance. This resistance increases the voltage to amplify the speed of this turbine. A bizarre ventilation malfunction may be related to a concern for resistance. This microchip is complicated to troubleshoot. It must be replaced.
HS blower motor
There are two fairly common malfunctions on the blower. The brushes may be damaged. The more time passes, they can wear out and generate false contact. The fan may run randomly, or may not work at all. It is also possible that the concern comes from bearings of the fan motor. When the ventilation produces a hissing sound, comparable to a rusty mechanism, it can happen that the bearings lack lubrication.
