Let's not confuse the air conditioning , heating and ventilation of this Smart For-us. Heating and air conditioning are devices that can lower or increase the air temperature. The very first by means of the heat produced by the engine block, and the second with the help of a liquid refrigerant . Your ventilation is the set of circuits and mechanisms that give the opportunity for air to arrive inside the vehicle. The main element will be the kicker which emits air into your vehicle. If there is little or no air supply, it is probably a malfunction of ventilation. We will see within this guide how ventilation works, so as to better discern dysfunctions and understand by what means to resolve it.
How ventilation works on a Smart For-us
The ventilation is primarily used to circulate the air inside the cabin of this Smart For-us. As for the pulser, it is generally composed of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine runs. By turning the button in the passenger compartment, the resistance is reduced.
Smart For-us: regular ventilation problems
Dirty air ducts
When the ventilation works but little air arrives inside the cabin of this Smart For-us, it is conceivable that the air shutters are cluttered. Using a screwdriver flat, you can remove the air shutter covers. It is only necessary to check inside if these are blocked. If this is what is happening you can clean them, but also the valves.
Dirty cabin filter
When you perceive fumes and your ventilation lacks intensity, the malfunction must probably come from the cabin filter of this Smart For-us. It gets dirty and piles up bacteria as time goes by. It remains totally common that it is dirty, it serves to clarify the air that reaches us. There is no manufacturer's recommendation on when to change it. We only advise you to remove it, look at its condition. When the latter is really black, it will be necessary to change it.
Resistance of the blower HS
When the ventilation buttons on the Smart For-us work poorly, or even not at all, it is probably related to resistance. This resistance is used to increase the voltage to increase the speed of the turbine. Inconsistent functioning of your ventilation may be linked to a resistance malfunction. This little microchip is complicated to troubleshoot. It will have to be changed.
HS blower motor
Several relatively recurring malfunctions can be found on the blower. The brushes are damaged. Over time, they will be able to deteriorate and generate electrical faults. The kicker may work randomly, or may not rotate at all. It is also possible that the malfunction comes from bearings of the fan motor. When the ventilation whistles, comparable to a rusty mechanism, the bearings may require lubrication. Do not hesitate to comment on this guide if your dysfunction is different to help our readers.
