Do not confuse the air conditioning , heating and ventilation of your Renault Espace 5. Heating and air conditioning are devices that decrease or increase the temperature. The first thanks to the heat produced by the engine block, and the second with the help of a fluid refrigerant . Your ventilation is the entirety of the channels and mechanisms that give the opportunity for air to get inside. The fundamental element will be the kicker which propels the air into your vehicle. If there is little or no air supply, it is probably a concern for ventilation. We will see through this file how ventilation works, in order to better perceive the problems and understand how to solve it.ventilation-problem-Renault-Espace-5

How does ventilation work on a Renault Espace 5

The ventilation is used first to circulate the air in the passenger compartment of your Renault Espace 5. For the blower, the latter generally consists of a resistance, a turbine, and a motor. The more the integral resistance of the circuit is reduced, the faster the turbine runs. By rotating the button in the vehicle, the resistance is therefore reduced.

Renault Espace 5: frequent ventilation problems

Dirty air ducts

If the ventilation turns but very little air arrives in the passenger compartment of your Renault Espace 5, it is conceivable that the air shutters are clogged. With the aid of screwdriver flat, it is possible to remove the valves from the air vents. You just have to take a look inside if they are clogged. When this is happening it is possible to clean them, but also the shutters.

Dirty cabin filter

When you perceive effluxes and your ventilation is poor, the problem certainly comes from the cabin filter of your Renault Espace 5. It gets dirty and accumulates bacteria with the years. It is quite normal that it is dirty, it is there to filter the air that reaches you. There is no manufacturer's recommendation as to when to change it. We only advise you to remove it, check its condition. If the latter is completely dirty, it will be necessary to replace it.

Resistance of the blower HS

If the ventilation buttons on your Renault Espace 5 work poorly, or even not at all, it is certainly linked to resistance. The resistance is used to increase the voltage in order to increase the speed of this turbine. A bizarre malfunction of your ventilation is probably due to a concern for resistance. This electronic chip is complex to repair. It must be replaced.

HS blower motor

There are several fairly regular problems with the kicker. The brushes may be worn out. Over the years, they can deteriorate and cause false contact. Your kicker may work randomly, and may not even operate at all. It is also possible that the concern comes from bearings of the motor. If the ventilation hisses, like a rusty mechanic, it can happen that the bearings require lubrication.
