Let's not confuse the air conditioning , heating and ventilation of this Lancia. Heating and air conditioning are devices that can lower or increase the air temperature. The first with the help of the heat produced from the engine, and the second with the help of a fluid refrigerant . Your ventilation is all the circuits and mechanisms that will allow air to get inside. The fundamental component will be kicker which propels the air into your automobile. In the event that the air hardly or even arrives at all, it is certainly a malfunction of ventilation. We will see in this article how a ventilation works, to be able to better discern the concerns and understand how to resolve it.
How ventilation works on a Lancia
The ventilation is used first to circulate the air inside the passenger compartment of this Lancia. As for the pulser, it is often composed of a resistor, a turbine, and a motor. The lower the total resistance of the electrical system, the faster the turbine turns. By rotating the switch in the passenger compartment, the resistance is reduced.
Lancia: regular ventilation problems
Dirty air ducts
If the ventilation works but very little air arrives in the passenger compartment of this Lancia, it is likely that the air shutters are blocked. Thanks to a screwdriver flat, it is possible to disassemble the air shutter valves. It is only necessary to check inside if these are blocked. If this is the case it is possible to clean them, but also the valves.
Dirty cabin filter
When you feel effluxes and the ventilation lacks intensity, the malfunction probably comes from the cabin filter of this Lancia. This clogs and accumulates bacteria as time goes by. It is completely normal that it is dirty, it is there to clarify the air which reaches us. There is no manufacturer's recommendation as to when to replace it. We simply advise you to remove it, look at its condition. If the latter is particularly dirty, it will be necessary to replace it.
Resistance of the blower HS
If the Lancia's ventilation controls aren't working well, if at all, it's probably related to resistance. This resistance is used to increase the voltage to amplify the speed of the turbine. A bizarre ventilation malfunction is probably due to a resistance malfunction. This little electronic chip is complicated to repair. It needs to be replaced.
HS blower motor
There are two rather recurring concerns about the kicker. The brushes may be damaged. Over time, they may deteriorate and produce false contact. Your fan can spin very randomly, and even not spin at all. The malfunction may also come from bearings of the fan motor. If the ventilation makes a sharp noise, comparable to a rusty mechanism, its bearings may require lubrication.
