Let's not confuse the air conditioning , heating and ventilation of the Renault Grand Scenic 2. The heating and air conditioning are mechanisms that allow the air temperature to be lowered or raised. The very first with the help of heat produced from the engine, and the other with the help of a fluid refrigerant . Ventilation is all the ducts and devices that will allow the air to reach the interior. The main component will be the kicker which sends the air through your vehicle. If little or no air comes in, it is certainly a ventilation malfunction. We will see in this guide how ventilation works, in order to better perceive the problems and understand how to remedy them.
How does ventilation work on a Renault Grand Scenic 2
The ventilation serves above all to circulate the air in the passenger compartment of the Renault Grand Scenic 2. As for the blower, it is usually made of a resistance, a turbine, and an engine. The lower the integral resistance of the circuit, the faster the turbine turns. By turning the switch in the vehicle, the resistance is therefore reduced.
Renault Grand Scenic 2: frequent ventilation problems
Dirty air ducts
When the ventilation is running but a small amount of air is entering the interior of the Renault Grand Scenic 2, it is possible that your air flaps are blocked. Using a screwdriver flat, do not hesitate to remove the valves from the air flaps. Just look inside to see if they are blocked. If this is what happens do not hesitate to scrub them and the shutters.
Dirty cabin filter
When you smell fumes and your ventilation is poor, the malfunction must probably come from the cabin filter of the Renault Grand Scenic 2. The latter clogs and accumulates bacteria with time. It is quite normal that it is clogged, it serves to clarify the air which reaches you. There is no manufacturer's instruction on when to replace it. It is stupidly advisable to take it apart, look at its condition. When the latter is totally dirty, it will be better to change it.
Resistance of the blower HS
When the ventilation controls in your Renault Grand Scenic 2 are not working well, if at all, it is probably due to resistance. The resistance is used to increase the voltage to increase the speed of the turbine. A bizarre malfunction in your ventilation may be due to a resistance malfunction. This electronic chip is difficult to repair. You're going to have to change it.
HS blower motor
There are several fairly regular issues with the kicker. The brushes are damaged. The more time passes, they can deteriorate and cause false contact. Your fan might run randomly, and even not turn at all. It is also possible that the malfunction is due to bearings of the motor. When the ventilation makes a hissing sound, like a rusty mechanism, it happens that the bearings need lubrication.
