Let's not confuse the air conditioning , heating and ventilation of your Volkswagen 1500. Heating and air conditioning are mechanisms that will reduce or increase the air temperature. The first by means of the heat produced from the engine block, and the second by means of a liquid refrigerant . Ventilation is all of the ducts and devices that will allow air to enter the passenger compartment. The essential element is the kicker which emits air into your cabin. In the event that the air hardly or even arrives at all, it is probably a ventilation malfunction. We will see with this text how a ventilation works, to better identify the problems and assimilate the technique to remedy them.
How a ventilation works on a Volkswagen 1500
Ventilation is used to start regenerating the air in the passenger compartment of your Volkswagen 1500. Regarding the blower, it often consists of a resistor, a turbine, and a motor. The more the integral resistance of the circuit is lowered, the faster the turbine turns. By turning the button in the passenger compartment, the resistance is therefore lowered.
Volkswagen 1500: usual ventilation problems
Dirty air ducts
If the ventilation works but a small amount of air enters the passenger compartment of your Volkswagen 1500, it is plausible that the air shutters are blocked. With the aid of screwdriver flat, do not hesitate to remove the air shutter covers. It is only necessary to check in if these are blocked. If ever, do not hesitate to dust them, but also the shutters.
Dirty cabin filter
When you perceive effluxes and the ventilation lacks intensity, the malfunction must probably come from the cabin filter of your Volkswagen 1500. It becomes blocked and accumulates bacteria as time goes by. It is really normal that it is dirty, it is there to clarify the air that reaches you. There is no manufacturer's instruction as to when to change it. We simply advise you to remove it, check its condition. In case it is completely dirty, it will be better to replace it.
Resistance of the blower HS
In case the ventilation adjustment of the Volkswagen 1500 works badly, or not at all, it is probably due to the resistance. The resistance is used to increase the voltage to increase the speed of the turbine. A suspicious ventilation dysfunction may be related to resistance malfunction. This small electronic chip is complex to repair. You will have to replace it.
HS blower motor
There are two fairly recurring problems on the kicker. The brushes are worn. Over the years, they will be able to deteriorate and generate false contact. The fan may run randomly, or even stop operating at all. It is also possible that the malfunction comes from bearings of the fan motor. If the ventilation produces a hissing sound, comparable to a rusty mechanism, the bearings may lack lubrication.
