Do not confuse the air conditioning , heating and ventilation of the Volkswagen Jetta. Heating and air conditioning are devices which offer the possibility of reducing or increasing the air temperature. The first by means of the heat produced by the engine block, and the other by means of a liquid refrigerant . The famous ventilation is all the ducts and systems that will allow air to get inside. The essential element will be kicker which sends air into your cabin. In the event that the air hardly or hardly reaches, this is probably a concern for ventilation. We will discover through this text how a breakdown works, so as to better perceive the problems and understand by what means to remedy them.
How a ventilation works on a Volkswagen Jetta
Ventilation initially serves to regenerate the air in the passenger compartment of the Volkswagen Jetta. Regarding the blower, it generally consists of a resistor, a turbine, and a motor. The more the integral resistance of the circuit is reduced, the faster the turbine runs. By turning the switch in the vehicle, the resistance is therefore lowered.
Volkswagen Jetta: usual ventilation problems
Dirty air ducts
When the ventilation works but a small amount of air enters the passenger compartment of the Volkswagen Jetta, it is plausible that the air shutters are blocked. With the aid of screwdriver flat, do not hesitate to remove the valves from the air vents. It is only necessary to check inside if these are blocked. If this is what happens, do not hesitate to clean them, but also the shutters.
Dirty cabin filter
If you ever smell odors and this ventilation lacks intensity, the problem probably comes from the cabin filter of the Volkswagen Jetta. The latter clogs and accumulates bacteria as time goes by. It is completely common for it to be dirty, it is there to clarify the air that reaches us. There is no instruction from the manufacturer as to when to replace it. It is advisable just to remove it, check its condition. When it is particularly dirty, it will need to be changed.
Resistance of the blower HS
When the ventilation adjustment of your Volkswagen Jetta works badly, or even really not, it is probably in connection with the resistance. The resistance allows to increase the voltage in order to increase the speed of the turbine. A bizarre malfunction of this ventilation is probably due to a concern for resistance. This little microchip is complicated to troubleshoot. It must be changed.
HS blower motor
There are two relatively regular problems with the kicker. The brushes are damaged. Over time, these can wear out and produce electrical faults. Your fan may spin very randomly, and may not even activate at all. It is also possible that the concern comes from bearings of the fan motor. When the ventilation whistles, like a rusty mechanic, the bearings may lack lubrication. Do not hesitate to comment on this text if ever your concern is different to help Internet users. Good walk!
