Do not confuse the air conditioning , heating and ventilation of this Volkswagen Iroc. Heating and air conditioning are systems that can lower or increase the air temperature. The very first through the heat produced by the engine, and the other with a fluid refrigerant . Your ventilation is the totality of the ducts and devices that give the opportunity for air to get inside the vehicle. The fundamental component is the kicker which propels the air into your vehicle. If the air barely or not at all arrives, it is probably a ventilation malfunction. We will see in this post how ventilation works, so that we can better identify problems and understand how to solve them.
How a ventilation works on a Volkswagen Iroc
The ventilation is primarily used to circulate the air in the passenger compartment of this Volkswagen Iroc. For the blower, it is generally made of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By turning the knob in the vehicle, the resistance is thus reduced.
Volkswagen Iroc: frequent ventilation problems
Dirty air ducts
When the ventilation works but a small amount of air arrives in the passenger compartment of this Volkswagen Iroc, it is conceivable that your air shutters are obstructed. With the aid of screwdriver flat, you can remove the valves from the air vents. You just have to take a look inside if they are crowded. When this is the case you can scour them, but also the valves.
Dirty cabin filter
When you smell odors and this ventilation lacks intensity, the malfunction probably comes from the cabin filter of this Volkswagen Iroc. It clogs and piles up bacteria with time. It remains quite common that it is dirty, it is there to clarify the air that reaches you. There is no instruction from the manufacturer as to when to replace it. We simply advise you to disassemble it, check its condition. When the latter is particularly black, it will be preferable to change it.
Resistance of the blower HS
When the ventilation adjustment of the Volkswagen Iroc does not work well, if not really, it is probably due to the resistance. The resistance allows to increase the voltage to increase the speed of this turbine. A bizarre malfunction of this ventilation is probably linked to a resistance malfunction. This little microchip is difficult to repair. We will have to change it.
HS blower motor
There are several fairly recurring problems on the kicker. The brushes are worn. Over time, these can wear out and cause electrical faults. The fan may run randomly, or even stop operating at all. It also happens that the dysfunction comes from bearings of the motor. When the ventilation produces a hissing sound, such as rusty mechanics, the bearings may require lubrication. Do not hesitate to comment on this post when your dysfunction is different to help other readers. See you soon!
