Let's not confuse the air conditioning , heating and ventilation of this Smart Crossblade. Heating and air conditioning are devices that offer the possibility of decreasing or amplifying the air temperature. The first by means of the heat emitted by the engine block, and the other by means of a liquid refrigerant . The famous ventilation is all of the channels and mechanisms that allow air to get inside. The fundamental element will be the kicker which propels the air into your automobile. If there is little or no air supply, it is probably a ventilation problem. We will see in this guide how ventilation works, in order to better identify malfunctions and understand how to remedy them.ventilation-problem-Smart-Crossblade

How ventilation works on a Smart Crossblade

Ventilation initially serves to regenerate the air in the passenger compartment of this Smart Crossblade. As for the blower, it often consists of a resistor, a turbine, and a motor. The more the integral resistance of the electrical system is lowered, the faster the turbine operates. By turning the button in the passenger compartment, the resistance is lowered.

Smart Crossblade: usual ventilation problems

Dirty air ducts

If the ventilation works but little air enters the cabin of this Smart Crossblade, it is conceivable that the air flaps are obstructed. With the aid of screwdriver flat, you can remove the covers from the air shutters. You just have to check inside if they are cluttered. If this is the case you can dust them, as well as the shutters.

Dirty cabin filter

If you ever smell odors and the ventilation is weak, the problem probably comes from the cabin filter of this Smart Crossblade. This becomes blocked and accumulates bacteria with the years. It is really normal that it is dirty, it is used to clarify the air that reaches you. There is no manufacturer's instruction as to when to change it. We advise you stupidly to disassemble it, check its condition. If the latter is completely black, it will need to be replaced.

Resistance of the blower HS

If the ventilation controls on the Smart Crossblade are malfunctioning, or even not at all, it is probably related to resistance. The resistance is used to increase the voltage to amplify the speed of the turbine. Suspicious ventilation may be linked to a resistance problem. This microchip is complicated to troubleshoot. It needs to be replaced.

HS blower motor

There are several relatively recurring malfunctions regarding the blower. The brushes may be worn out. Over time, they will be able to be damaged and produce false contact. Your fan may spin very randomly, and even stop working at all. It also happens that the problem stems from bearings of the fan motor. If the ventilation hisses, like a rusty mechanic, it can happen that its bearings require lubrication.
