Let's not confuse the air conditioning , heating and ventilation of this Lancia Delta. Heating and air conditioning are devices that offer the possibility of reducing or increasing the air temperature. The first thanks to the heat generated by the engine, and the second using a liquid refrigerant . Your ventilation is the entirety of the channels and mechanisms that give the opportunity for air to get inside. The fundamental element will be the kicker which emits air into your cabin. In the event that the air barely or not at all reaches, it is certainly a malfunction of ventilation. We will discover in this article how ventilation works, so as to better discern dysfunctions and understand how to remedy them.ventilation-problem-Lancia-Delta

How ventilation works on a Lancia Delta

The ventilation is primarily used to circulate the air inside the cabin of this Lancia Delta. For the blower, it generally consists of a resistor, a turbine, and a motor. The more the total resistance of the circuit is reduced, the faster the turbine operates. By rotating the switch in the vehicle, the resistance is therefore lowered.

Lancia Delta: usual ventilation problems

Dirty air ducts

If the ventilation does work but very little air enters the passenger compartment of this Lancia Delta, it is likely that these air flaps are blocked. Using a screwdriver flat, it is possible to remove the valves from the air vents. You just have to look inside if they are blocked. If this is what is happening it is possible to clean them, but also the shutters.

Dirty cabin filter

If you ever feel effluxes and the ventilation lacks power, the malfunction probably comes from the cabin filter of this Lancia Delta. It clogs and piles up bacteria as time goes by. It is quite normal that it is dirty, it is there to filter the air that reaches you. There is no instruction from the manufacturer as to when to replace it. We only advise you to remove it, check its condition. If it is ever completely dirty, it will need to be changed.

Resistance of the blower HS

If the ventilation controls on your Lancia Delta ever work poorly, or even not at all, it's probably related to resistance. This resistance is used to increase the voltage to increase the speed of this turbine. A strange functioning of the ventilation is probably linked to a resistance malfunction. This electronic chip is complex to repair. We will have to change it.

HS blower motor

There are two relatively regular malfunctions on the blower. The brushes are damaged. The more time passes, they will be able to wear out and produce false contact. Your fan may run randomly, and may not even spin at all. It also happens that the dysfunction comes from bearings of the motor. If the ventilation whistles, like a rusty mechanic, it is possible that its bearings require lubrication. Do not hesitate to comment on this article when your dysfunction is different to help our readers. Enjoy the road!
