Do not confuse the air conditioning , heating and ventilation of the Volkswagen Bora. Heating and air conditioning are mechanisms that lower or increase the temperature. The first with the help of the heat generated by the engine block, and the other with the help of a liquid refrigerant . Ventilation is the totality of ducts and systems that give the possibility of air entering the interior. The main element will be the kicker which emits air into your cabin. If there is very little or no air, this is probably a ventilation problem. We will discover in this guide how a ventilation works, to be able to better discern the problems and understand by what means to remedy them.
How a ventilation works on a Volkswagen Bora
Ventilation first of all serves to regenerate the air inside the passenger compartment of the Volkswagen Bora. For the blower, the latter is often made of a resistor, a turbine, and a motor. The more the total resistance of the circuit is reduced, the faster the turbine operates. By rotating the switch in the vehicle, the resistance is therefore lowered.
Volkswagen Bora: regular ventilation problems
Dirty air ducts
If the ventilation works but very little air arrives in the passenger compartment of the Volkswagen Bora, it is plausible that the air shutters are clogged. Using a screwdriver flat, it is possible to remove the covers of the air vents. You just have to check in if they are blocked. When this is the case, it is possible to dust them, but also the valves.
Dirty cabin filter
When you feel efflux and your ventilation lacks intensity, the problem probably comes from the cabin filter of the Volkswagen Bora. It clogs and piles up bacteria with time. It is really normal that this one is dirty, it is there to purify the air which reaches us. There is no recommendation from the manufacturer as to when to change it. It is simply advised to dismantle it, check its condition. If the latter is completely black, it will be preferable to replace it.
Resistance of the blower HS
If the ventilation buttons on your Volkswagen Bora do not work well, if not really, it is probably related to the resistance. The resistance increases the voltage to increase the speed of this turbine. A strange functioning of your ventilation can be linked to a resistance problem. This microchip is difficult to repair. It will have to be replaced.
HS blower motor
There are several rather common problems with the kicker. The brushes may be damaged. Over the years, they can wear out and produce electrical faults. The fan may run randomly, and may not even spin at all. In addition, the problem may arise from bearings of the fan motor. If the ventilation whistles, comparable to a rusty mechanism, it is possible that the bearings lack lubrication. Feel free to comment on this guide if your problem is different to help other readers.
