Let's not confuse the air conditioning , heating and ventilation of your Citroen Visa. Heating and air conditioning happen to be systems that lower or increase the air temperature. The very first thanks to the heat generated by the engine block, and the other with a liquid refrigerant . Ventilation is the totality of ducts and mechanisms that give the opportunity for air to reach the interior. The main element is the kicker which sends air into your vehicle. In the event that there is very little or no air supply, this is probably a concern for ventilation. We will see in this post how a ventilation works, to be able to better discern the concerns and apprehend by what means to resolve it.problem-ventilation-Citroen-Visa

How does ventilation work on a Citroen Visa

The ventilation is first of all used to circulate the air in the passenger compartment of your Citroen Visa. Regarding the blower, the latter 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 turning the switch in the passenger compartment, the resistance is reduced.

Citroen Visa: common ventilation problems

Dirty air ducts

When the ventilation turns but little air enters the interior of your Citroen Visa, it is plausible that these air flaps are obstructed. Thanks to a screwdriver flat, do not hesitate to disassemble the air shutter covers. It will be enough to look inside if they are cluttered. If this is what is happening do not hesitate to clean them, as well as the valves.

Dirty cabin filter

If you discern fumes and this ventilation lacks power, the problem probably comes from the cabin filter of your Citroen Visa. The latter becomes blocked and accumulates bacteria with the years. It is really common that this one is dirty, it is there to filter the air which reaches us. There is no manufacturer's recommendation on when to replace it. We simply advise you to remove it, look at its condition. When the latter is particularly black, it will be preferable to replace it.

Resistance of the blower HS

When the ventilation buttons on your Citroen Visa work poorly, or not at all, it is likely related to the resistance. The resistance allows to raise the voltage to be able to amplify the speed of this turbine. A strange malfunction of this ventilation is probably linked to a concern for resistance. This electronic chip is complicated to repair. It needs to be replaced.

HS blower motor

There are several fairly regular concerns about the kicker. The brushes may be damaged. As time goes by, these can deteriorate and cause electrical faults. The kicker can work randomly or even stop working at all. It also happens that the concern comes from bearings of the motor. When the ventilation whistles, like a rusty mechanic, it happens that the bearings lack lubrication. Do not hesitate to comment on this post if your concern is different to help Internet users.
