Let's not confuse the air conditioning , heating and ventilation Renault Espace 4. Heating and air conditioning are systems that can lower or increase the air temperature. The very first thanks to the heat produced by the engine, and the second with the help of a liquid refrigerant . Ventilation is all of the circuits and mechanisms that give air the opportunity to get into the passenger compartment. The fundamental element will be the kicker which emits air into your vehicle. In the event that the air reaches very little if any, it is probably a concern of ventilation. We will see in this article how a ventilation works, in order to better discern the concerns and understand how to resolve it.
How does ventilation work on a Renault Espace 4
The ventilation is used initially to regenerate the air in the passenger compartment of the Renault Espace 4. For the blower, the latter is generally made of a resistance, a turbine, and a motor. The more the total resistance of the electrical system is reduced, the faster the turbine operates. By turning the knob in the vehicle, the resistance is reduced.
Renault Espace 4: common ventilation problems
Dirty air ducts
If the ventilation turns but little air reaches the interior of the Renault Espace 4, the air flaps may be blocked. Thanks to a screwdriver flat, you can disassemble the air flap valves. It is only necessary to check inside if these are blocked. If this is the case you can scour them, but also the valves.
Dirty cabin filter
When you perceive odors and the ventilation lacks intensity, the concern must undoubtedly come from the cabin filter of the Renault Espace 4. The latter becomes blocked and accumulates bacteria with the years. It is completely common that it is dirty, it serves to purify the air that reaches us. There is no manufacturer's instruction as to when to change it. We stupidly advise you to disassemble it, look at its condition. If it is really dirty, it will need to be changed.
Resistance of the blower HS
If the ventilation adjustment of your Renault Espace 4 malfunctions, or even really does not, it is probably due to the resistance. The resistance is used to increase the voltage to increase the speed of this turbine. Inconsistent ventilation operation is probably linked to a concern for resistance. This little microchip is difficult to repair. It is necessary to change it.
HS blower motor
There are several rather recurring concerns about the kicker. The brushes may be damaged. Over time, they will be able to be damaged and produce electrical faults. Your kicker may spin randomly, or not activate at all. The concern may also arise from bearings of the motor. If the ventilation makes a sharp noise, such as a rusty mechanism, it is possible that its bearings require lubrication.
