Do not confuse the air conditioning , heating and ventilation of the Nissan Interstar Minibus. Heating and air conditioning are devices which give the possibility of lowering or amplifying the temperature. The first through the heat emitted by the engine block, and the second using a fluid refrigerant . Ventilation is all the channels and systems that will allow air to enter the passenger compartment. The main component will be kicker which sends air into your automobile. If there is little or no air supply, it is probably a ventilation problem. We will see in this article how ventilation works, in order to better identify malfunctions and assimilate by what means to resolve it.
How ventilation works on a Nissan Interstar Minibus
The ventilation is primarily used to regenerate the air inside the interior of the Nissan Interstar Minibus. For the blower, the latter is generally composed of a resistor, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine turns. By turning the button in the passenger compartment, the resistance is reduced.
Nissan Interstar Minibus: frequent ventilation problems
Dirty air ducts
When ventilation works but little air enters the interior of the Nissan Interstar Minibus, it is plausible that the air shutters are clogged. Using a screwdriver flat, it is possible to remove the air flap valves. It will suffice to look inside if they are obstructed. If this is what is happening it is possible to dust them, as well as the shutters.
Dirty cabin filter
In case you smell odors and the ventilation is weak, the concern must undoubtedly come from the cabin filter of the Nissan Interstar Minibus. It is blocked and piled up bacteria as time goes by. It is completely normal for it to be dirty, it is there to clarify the air that reaches you. There is no manufacturer's instruction as to when to change it. We just advise you to take it apart, look at its condition. When the latter is really black, it will be better to change it.
Resistance of the blower HS
When the ventilation buttons on your Nissan Interstar Minibus do not work well, or really do not, it is probably related to the resistance. The resistance is used to increase the voltage to be able to amplify the speed of this turbine. A strange ventilation malfunction may be due to a concern for resistance. This little microchip is complicated to troubleshoot. It is necessary to change it.
HS blower motor
There are two rather common malfunctions on the blower. The brushes can be damaged. The more time passes, the latter will be able to be damaged and cause false contact. The pulser may rotate very randomly, and even not work at all. The concern may also arise from bearings of the motor. When the ventilation makes a sharp noise, like a rusty mechanic, its bearings may require lubrication. Feel free to comment on this article if your concern is different to help other readers. Good walk!
