Let's not confuse the air conditioning , heating and ventilation of your Renault Espace. Heating and air conditioning are mechanisms that offer the possibility of reducing or increasing the temperature. The very first passing through the heat emitted by the engine block, and the other using a fluid refrigerant . Your ventilation is all the channels and devices that allow air to enter the passenger compartment. The fundamental element is the kicker which sends air into your vehicle. If there is little or no air supply, it is most likely a ventilation problem. We will discover through this article how a ventilation works, in order to better perceive the concerns and assimilate the technique to remedy them.ventilation-problem-Renault-Espace

How does ventilation work on a Renault Espace

Ventilation is primarily used to regenerate the air in the passenger compartment of your Renault Espace. For the blower, the latter is usually made of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine operates. By turning the button in the passenger compartment, the resistance is lowered.

Renault Espace: usual ventilation problems

Dirty air ducts

When the ventilation works but very little air arrives inside the cabin of your Renault Espace, it is possible that your air shutters are blocked. With the aid of screwdriver flat, do not hesitate to dismantle the covers of the air vents. It will be enough to look inside if they are blocked. When this is happening do not hesitate to scour them, but also the valves.

Dirty cabin filter

If you feel effluxes and this ventilation is weak, the problem probably comes from the cabin filter of your Renault Espace. It gets dirty and piles up bacteria with the years. It is completely common that it is dirty, it is used to filter the air that reaches us. There is no manufacturer's instruction on when to change it. We simply advise you to disassemble it, look at its condition. When the latter is completely black, it will be necessary to change it.

Resistance of the blower HS

When the ventilation adjustment of your Renault Espace is not working well, or even really not, 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 bizarre functioning of this ventilation is probably due to a resistance problem. This little microchip is difficult to repair. It is necessary to change it.

HS blower motor

There are two relatively common concerns about the kicker. The brushes are damaged. Over the years, they will be able to deteriorate and produce false contact. Your fan may run very randomly, and may not work at all. In addition, the problem may arise from bearings of the motor. When the ventilation whistles, like a rusty mechanic, its bearings may lack lubrication. Feel free to comment on this article in case your problem is different in order to help other readers.
