Do not confuse the air conditioning , heating and ventilation of your Renault Espace 3. Heating and air conditioning are mechanisms that offer the possibility of decreasing or increasing the air temperature. The very first with the help of the heat produced by the engine block, and the second with the help of a liquid refrigerant . Ventilation is the totality of channels and mechanisms that allow air to arrive inside the vehicle. The main component will be kicker which propels the air within your automobile. In the event that there is very little or no air, this is probably a ventilation problem. We will discover within this post how a ventilation works, so as to better identify the concerns and understand by what means to resolve it.ventilation-problem-Renault-Espace-3

How does ventilation work on a Renault Espace 3

Ventilation is primarily used to circulate the air in the interior of your Renault Espace 3. As for the blower, it is usually composed of a resistor, a turbine, and a motor. The more the integral resistance of the electrical system is reduced, the faster the turbine runs. By turning the button in the passenger compartment, the resistance is therefore reduced.

Renault Espace 3: common ventilation problems

Dirty air ducts

If the ventilation works but a small amount of air enters the interior of your Renault Espace 3, it is possible that the air shutters are clogged. Thanks to a screwdriver flat, it is possible to remove the covers from the air shutters. You just have to check inside if they are blocked. When this is the case it is possible to scour them, as well as the shutters.

Dirty cabin filter

When you feel effluxes and your ventilation is poor, the problem probably comes from the cabin filter of your Renault Espace 3. It becomes clogged and accumulates bacteria as time goes by. It is completely common that it is dirty, it is used to filter the air that reaches us. There is no recommendation from the manufacturer as to when to replace it. We advise you stupidly to remove it, check its condition. If it is particularly black, it will be better to replace it.

Resistance of the blower HS

If the ventilation buttons on your Renault Espace 3 do not work well, if at all, it is probably due to the resistance. This resistance is used to increase the voltage in order to increase the speed of this turbine. A strange functioning of your ventilation can be linked to a resistance problem. This little microchip is complicated to troubleshoot. You will have to replace it.

HS blower motor

There are two fairly regular concerns about the kicker. The brushes are worn. The more time passes, they will be able to deteriorate and produce electrical faults. The kicker could work very randomly, and even not work at all. It also happens that the problem comes from bearings of the fan motor. If the ventilation hisses, comparable to a rusty mechanism, it can happen that the bearings require lubrication.
