Let's not confuse the air conditioning , heating and ventilation of the Smart Forvision. Heating and air conditioning are mechanisms that will lower or increase the temperature. The first by means of the heat emitted by the engine, and the other with a liquid refrigerant . Your ventilation is the totality of channels and mechanisms that allow air to enter the interior. The fundamental component is the kicker which propels the air within your vehicle. If there is little or no air supply, it is certainly a ventilation problem. We will see through this guide how a ventilation works, to be able to better discern the concerns and understand how to resolve it.problem-ventilation-Smart-Forvision

How ventilation works on a Smart Forvision

Ventilation is used to begin to regenerate the air inside the interior of the Smart Forvision. Regarding the pulser, it is often composed of a resistor, a turbine, and a motor. The more the integral resistance of the circuit is lowered, the faster the turbine operates. By rotating the switch in the passenger compartment, the resistance is thus reduced.

Smart Forvision: usual ventilation problems

Dirty air ducts

If ventilation does work but little air enters the interior of the Smart Forvision, it is plausible that these air flaps are clogged. With the aid of screwdriver flat, do not hesitate to remove the valves from the air vents. It is only necessary to check in if these are congested. If this is what is happening, do not hesitate to dust them, as well as the shutters.

Dirty cabin filter

If you can see odors and this ventilation lacks intensity, the problem probably comes from the Smart Forvision cabin filter. It gets dirty and accumulates bacteria with the years. It is really normal that this one is dirty, it is there to purify the air which reaches us. There is no manufacturer's instruction on when to change it. It is advisable simply to remove it, check its condition. If it is completely dirty, it will be better to replace it.

Resistance of the blower HS

If the Smart Forvision's ventilation controls ever work badly, or not at all, it's probably due to resistance. The resistance is used to increase the voltage in order to amplify the speed of this turbine. Inconsistent operation 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

One can find several rather common concerns on the kicker. The brushes may be damaged. The more time passes, they can wear out and cause electrical faults. Your kicker may work randomly, or not spin at all. The problem may also arise from bearings of the fan motor. If the ventilation whistles, like a rusty mechanic, its bearings may lack lubrication.
