Do not confuse the air conditioning , heating and ventilation of your Renault Grand Scenic 3. Heating and air conditioning are systems which reduce or increase the temperature. The very first through the heat emitted from the engine, and the second with a liquid refrigerant . Ventilation is all the ducts and systems that allow air to reach the passenger compartment. The essential component is the kicker that sends air into your automobile. If ever the air is barely or not at all, it is probably a ventilation problem. In this post, we will discover how ventilation works, in order to better identify dysfunctions and understand how to remedy them.ventilation-problem-Renault-Grand-Scenic-3

How does ventilation work on a Renault Grand Scenic 3

The ventilation is used to start regenerating the air in the passenger compartment of your Renault Grand Scenic 3. As for the blower, it usually consists of a resistance, a turbine, and an engine. The more the total resistance of the electrical system is reduced, the faster the turbine runs. By turning the button in the vehicle, the resistance is therefore reduced.

Renault Grand Scenic 3: usual ventilation problems

Dirty air ducts

If the ventilation is working but a small amount of air is entering the passenger compartment of your Renault Grand Scenic 3, it is conceivable that these air flaps are cluttered. With the aid of screwdriver flat, it is possible to remove the air flap covers. It is only necessary to check inside if they are blocked. If this is the case it is possible to scour them, but also the valves.

Dirty cabin filter

If you discern smells and your ventilation is poor, the problem probably stems from the cabin filter of your Renault Grand Scenic 3. The latter becomes clogged and accumulates bacteria as time goes by. It is still really common that it is dirty, it is there to clarify the air which reaches you. There is no recommendation from the manufacturer as to when to replace it. It is stupidly advisable to take it apart, look at its condition. If it is really dirty, it will be better to replace it.

Resistance of the blower HS

If the ventilation settings on your Renault Grand Scenic 3 are not working well, if at all, it is probably due to resistance. The resistance is used to increase the voltage to amplify the speed of this turbine. An inconsistent operation of your ventilation may be related to a concern for resistance. This electronic chip is difficult to troubleshoot. It is necessary to replace it.

HS blower motor

There are several rather recurring malfunctions on the kicker. The brushes may be damaged. Over time, these can wear out and produce false contact. The kicker can spin very randomly, and even not activate at all. It may also be that the concern comes from bearings of the motor. If the ventilation makes a high-pitched noise, like rusty mechanics, its bearings may need lubrication. Do not hesitate to comment on this post if your concern is different to help Internet users.
