Do not confuse the air conditioning , heating and ventilation of this Volkswagen 1303. Heating and air conditioning are devices that offer the possibility of lowering or increasing the air temperature. The first through the heat produced by the engine, and the second with the help of a fluid refrigerant . Your ventilation is all the ducts and systems that allow air to enter the passenger compartment. The main component will be kicker which emits air in your automobile. In the event that little or no air comes in, this is probably a malfunction of ventilation. We will discover within this guide how ventilation works, so as to better identify malfunctions and understand by what means to remedy them.ventilation-problem-Volkswagen-1303

How ventilation works on a Volkswagen 1303

The ventilation is used first to regenerate the air inside the passenger compartment of this Volkswagen 1303. For the blower, this usually 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 knob in the passenger compartment, the resistance is therefore reduced.

Volkswagen 1303: regular ventilation problems

Dirty air ducts

If the ventilation turns but little air arrives in the passenger compartment of this Volkswagen 1303, it is plausible that the air shutters are clogged. With the aid of screwdriver flat, it is possible to remove the covers from the air shutters. It will suffice to check inside if these are obstructed. When this is the case, it is possible to dust them, but also the valves.

Dirty cabin filter

When you smell fumes and your ventilation is lacking in power, the malfunction probably comes from the cabin filter of this Volkswagen 1303. It gets blocked and accumulates bacteria with time. It is completely common that it is dirty, it is used to filter the air that reaches us. There is no manufacturer's recommendation as to when to replace it. We simply advise you to remove it, check its condition. If the latter is completely black, it will be necessary to change it.

Resistance of the blower HS

If the ventilation buttons on your Volkswagen 1303 are not working well, or even really not, it is probably due to the resistance. This resistance increases the voltage to increase the speed of the turbine. A suspicious functioning of your ventilation is probably linked to a resistance malfunction. This electronic chip is complex to repair. It will have to be changed.

HS blower motor

There are two fairly regular malfunctions on the blower. The brushes may be damaged. The more time passes, they will be able to deteriorate and produce electrical faults. Your fan may spin very randomly, and even stop working at all. It is also possible that the malfunction comes from bearings of the motor. If the ventilation makes a sharp noise, such as a rusty mechanism, its bearings may lack lubrication. We invite you to comment on this guide if your dysfunction is different to help other readers.
