Do not confuse the air conditioning , heating and ventilation of the Lancia Delta 2. Heating and air conditioning are systems that will reduce or increase the air temperature. The very first by means of the heat generated by the engine block, and the other with the help of a fluid refrigerant . Your ventilation is all of the circuits and devices that allow air to reach the interior of the vehicle. The essential element will be kicker which propels the air inside your cabin. In the event that the air barely, if at all, reaches the air, this is most likely a ventilation problem. We will discover in this post how a ventilation works, so as to better identify the problems and understand the technique to remedy them.ventilation-problem-Lancia-Delta-2

How ventilation works on a Lancia Delta 2

Ventilation is primarily used to regenerate the air in the interior of the Lancia Delta 2. For the blower, the latter is generally made of a resistance, a turbine, and a motor. The lower the integral resistance of the circuit, the faster the turbine runs. By turning the switch in the passenger compartment, the resistance is therefore reduced.

Lancia Delta 2: frequent ventilation problems

Dirty air ducts

If the ventilation turns but very little air arrives inside the cabin of the Lancia Delta 2, it is plausible that the air shutters are blocked. Thanks to a screwdriver flat, do not hesitate to remove the covers from the air vents. It will be enough to look inside if they are blocked. When this is happening do not hesitate to clean them, as well as the valves.

Dirty cabin filter

When you perceive effluxes and this ventilation is weak, the problem probably comes from the cabin filter of the Lancia Delta 2. It clogs and accumulates bacteria with the years. It is quite common that it is dirty, it serves to clarify the air that reaches us. There is no manufacturer's instruction as to when to change it. It is advisable simply to dismantle it, check its condition. If the latter is really black, it will be necessary to replace it.

Resistance of the blower HS

If the ventilation buttons on the Lancia Delta 2 are malfunctioning, or even really not, it's probably related to resistance. This resistance is used to increase the voltage to increase the speed of this turbine. A suspicious dysfunction of this ventilation is probably linked to a resistance problem. This electronic chip is complicated to repair. It will have to be replaced.

HS blower motor

There are two rather recurring problems with the kicker. The brushes may be worn out. The more time passes, they will be able to wear out and generate false contact. The kicker may work randomly, or may not work at all. It also happens that the problem stems from bearings of the motor. If the ventilation makes a sharp noise, comparable to a rusty mechanism, its bearings may require lubrication.
