Let's not confuse the air conditioning , heating and ventilation of the Citroen Picasso. Heating and air conditioning happen to be mechanisms that reduce or increase the air temperature. The first using the heat generated by the engine block, and the other using a liquid refrigerant . Your ventilation is all the channels and devices that give the air the opportunity to reach the passenger compartment. The essential component will be the kicker that sends air into your automobile. In the event that the air barely arrives or not at all, it is probably a ventilation problem. We will discover within this file how a ventilation works, in order to better perceive the problems and understand how to remedy them.problem-ventilation-Citroen-Picasso

How ventilation works on a Citroen Picasso

The ventilation is first used to regenerate the air in the passenger compartment of the Citroen Picasso. Regarding the blower, it often consists of a resistance, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By turning the switch in the vehicle, the resistance is therefore reduced.

Citroen Picasso: regular ventilation problems

Dirty air ducts

If the ventilation is running but little air is entering the passenger compartment of the Citroen Picasso, it is likely that the air flaps are blocked. Using a screwdriver flat, you can remove the flaps from the air flaps. You just have to check if they are blocked. If this is the case you can dust them, but also the valves.

Dirty cabin filter

When you discern smells and this ventilation lacks power, the concern probably comes from the cabin filter of the Citroen Picasso. The latter becomes blocked and accumulates bacteria as time goes by. It is completely normal that this one is clogged, it is used to filter the air which arrives to you. There is no instruction from the manufacturer on when to replace it. We simply advise you to take it apart and check its condition. If the latter is particularly black, it will be necessary to change it.

Resistance of the blower HS

If the ventilation adjustment of your Citroen Picasso works poorly, if at all, it is probably related to the resistance. This resistance is used to increase the voltage to be able to increase the speed of the turbine. An inconsistent malfunction of this ventilation is undoubtedly linked to a concern for resistance. This electronic chip is complicated to troubleshoot. We will have to change it.

HS blower motor

There are several fairly common issues with the kicker. The brushes are damaged. Over the years, they may deteriorate and produce false contact. Your fan may run randomly, or even stop working at all. It is also possible that the concern arose from bearings of the fan motor. In the event that the ventilation produces a hissing sound, such as rusty mechanics, it happens that the bearings lack lubrication.
