Let's not confuse the air conditioning , heating and ventilation of the Suzuki Vitara 4. Heating and air conditioning are systems that give the possibility of reducing or increasing the air temperature. The first thanks to the heat produced by the engine block, and the other with a fluid refrigerant . Your ventilation is all of the ducts and mechanisms that allow air to reach the interior. The main element is the kicker which propels the air into your cabin. In the event that the air hardly or hardly arrives at all, it is undoubtedly a concern of ventilation. We will see in this article how ventilation works, in order to better discern the problems and assimilate by what means to resolve it.ventilation-problem-Suzuki-Vitara-4

How ventilation works on a Suzuki Vitara 4

The ventilation is used first to circulate the air inside the passenger compartment of the Suzuki Vitara 4. As for the blower, it is often made of a resistance, a turbine, and d 'a motor. The more the integral resistance of the circuit is lowered, the faster the turbine runs. By rotating the switch in the passenger compartment, the resistance is therefore lowered.

Suzuki Vitara 4: usual ventilation problems

Dirty air ducts

If the ventilation works but very little air arrives in the interior of the Suzuki Vitara 4, it is possible that these air flaps are clogged. With the aid of screwdriver flat, it is possible to remove the air flap valves. You just have to look inside if they are blocked. If this is the case it is possible to dust them, but also the valves.

Dirty cabin filter

If you ever perceive fumes and that this ventilation is weak, the concern probably comes from the cabin filter of the Suzuki Vitara 4. It clogs and accumulates bacteria with the years. It is completely normal that this one is dirty, it is used to filter the air which reaches you. There is no manufacturer's recommendation as to when to replace it. We simply advise you to remove it, check its condition. If it is completely black, it will be better to replace it.

Resistance of the blower HS

If the ventilation buttons on your Suzuki Vitara 4 do not work well, or really do not, it is probably due to the resistance. The resistance is used to increase the tension to increase the speed of this turbine. A bizarre malfunction of this ventilation is probably related to a concern for resistance. This little microchip is complex to troubleshoot. It will have to be replaced.

HS blower motor

There are two fairly regular problems with the kicker. The brushes may be damaged. The more time passes, they will be able to wear out and generate false contact. The fan may run very randomly, or may not spin at all. It is also possible that the concern comes from bearings of the fan motor. If the ventilation makes a sharp noise, like a rusty mechanism, it can happen that its bearings require lubrication.
