Let's not confuse the air conditioning , heating and ventilation of your Iveco Daily Van. Heating and cooling are systems that can lower or increase the temperature. The first through the heat emitted by the engine block, and the other with a liquid refrigerant . Your ventilation is the totality of channels and mechanisms that give the opportunity for air to get inside the vehicle. The essential element is the kicker which emits air in your automobile. If the air hardly ever comes in or not at all, it is certainly a malfunction of ventilation. We will see through this file how a ventilation works, to be able to better discern the problems and understand by what means to resolve it.ventilation-problem-Iveco-Daily-Van

How ventilation works on an Iveco Daily Van

Ventilation is used to begin to regenerate the air inside the cabin of your Iveco Daily Van. For the blower, it usually consists of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By turning the knob in the passenger compartment, the resistance is thus reduced.

Iveco Daily Van: frequent ventilation problems

Dirty air ducts

When the ventilation works but little air arrives in the interior of your Iveco Daily Van, it is likely that these air shutters are blocked. Using a screwdriver flat, do not hesitate to remove the valves from the air vents. It is only necessary to look into it if these are cluttered. If ever, do not hesitate to dust them, but also the shutters.

Dirty cabin filter

If you perceive odors and this ventilation lacks intensity, the malfunction certainly comes from the cabin filter of your Iveco Daily Van. The latter clogs and accumulates bacteria as time goes by. It is really normal that it is dirty, it is there to purify the air that reaches you. There is no manufacturer's instruction on when to replace it. We only advise you to disassemble it, look at its condition. When it is completely black, it will be necessary to replace it.

Resistance of the blower HS

When the ventilation buttons on the Iveco Daily Van do not work well, or even not at all, it is certainly related to the resistance. This resistance increases the voltage to increase the speed of this turbine. Inconsistent functioning of this ventilation is probably linked to a resistance malfunction. This microchip is complex to troubleshoot. You will have to replace it.

HS blower motor

There are several relatively common problems with the kicker. The brushes may be damaged. Over time, they will be able to be damaged and cause electrical faults. The fan may run randomly or even not rotate at all. It also happens that the dysfunction comes from bearings of the fan motor. When the ventilation makes a sharp noise, such as a rusty mechanism, the bearings may lack lubrication. Do not hesitate to comment on this file if your dysfunction is different in order to help other readers. See you soon!
