Let's not confuse the air conditioning , heating and ventilation of the smart smart. Heating and air conditioning are mechanisms that offer the possibility of lowering or increasing the temperature. The very first thanks to the heat emitted from the engine, and the other using a liquid refrigerant . The famous ventilation is all the circuits and systems that give the opportunity for air to reach the cabin. The essential component will be kicker which emits air into your vehicle. If the air hardly or not at all arrives, it is undoubtedly a ventilation malfunction. We will see within this text how a ventilation works, so as to better identify the malfunctions and understand the technique to resolve it.
How ventilation works on a smart smart
The ventilation is primarily used to regenerate the air inside the interior of the smart smart. For the blower, the latter is generally made of a resistor, a turbine, and a motor. The lower the integral resistance of the circuit, the faster the turbine runs. By turning the switch in the vehicle, the resistance is therefore reduced.
smart smart: frequent ventilation problems
Dirty air ducts
If the ventilation works but little air enters the interior of the smart smart, the air flaps may be blocked. Thanks to a screwdriver flat, it is possible to remove the valves from the air vents. You just need to check inside if they are clogged. If this is the case it is possible to scour them, but also the shutters.
Dirty cabin filter
If you ever notice fumes and the ventilation lacks power, the malfunction must certainly come from the cabin filter of the smart smart. It clogs and piles up bacteria as time goes by. It is really common that it is dirty, it is there to purify the air that reaches you. There is no manufacturer's recommendation on when to change it. It is advisable simply to dismantle it, look at its condition. In case it is really black, it will be better to replace it.
Resistance of the blower HS
If the ventilation controls on your smart smart do not work well, if not really, it is certainly linked to resistance. This resistance is used to raise the voltage to increase the speed of this turbine. A bizarre ventilation operation is probably due to a resistance malfunction. This little microchip is complicated to troubleshoot. It needs to be replaced.
HS blower motor
Several relatively recurring malfunctions can be found on the blower. The brushes may be damaged. Over time, these can be damaged and cause false contact. Your fan may run very randomly, and may not even run at all. It also happens that the dysfunction comes from bearings of the motor. If the ventilation produces a hissing sound, such as a rusty mechanism, the bearings may lack lubrication. Do not hesitate to comment on this text when your dysfunction is different in order to help other readers. Good road!
