Let's not confuse the air conditioning , heating and ventilation of your Renault Grand Kangoo. Heating and air conditioning are devices that reduce or amplify the air temperature. The first by means of the heat generated from the engine block, and the other with a liquid refrigerant . Your ventilation is the totality of the ducts and systems which give the opportunity for air to enter the passenger compartment. The fundamental component will be kicker which propels the air inside your cabin. If there is very little or no air supply, it is certainly a ventilation problem. This guide will show you how ventilation works, so that you can better identify malfunctions and understand how to remedy them.
How does ventilation work on a Renault Grand Kangoo
The ventilation is primarily used to circulate the air inside the cabin of your Renault Grand Kangoo. For the blower, it often consists of a resistor, a turbine, and a motor. The lower the integral resistance of the circuit, the faster the turbine operates. By rotating the switch in the passenger compartment, the resistance is therefore lowered.
Renault Grand Kangoo: usual ventilation problems
Dirty air ducts
If the ventilation turns but a small amount of air enters the interior of your Renault Grand Kangoo, it is plausible that these air flaps are blocked. With the aid of screwdriver flat, do not hesitate to remove the air flap valves. You just have to look inside if they are cluttered. If this is what happens, do not hesitate to clean them, but also the valves.
Dirty cabin filter
If you feel effluxes and your ventilation lacks power, the problem probably comes from the cabin filter of your Renault Grand Kangoo. The latter clogs and accumulates bacteria with the years. It is completely common that it is dirty, it is there to purify the air that reaches us. There is no manufacturer's recommendation as to when to change it. It is advised simply 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 setting of your Renault Grand Kangoo is not working well, or even really not, it is probably related to the resistance. The resistance increases the voltage so that the speed of the turbine can be amplified. A shady operation of your ventilation is probably linked to a concern for resistance. This little microchip is complicated to troubleshoot. You will have to replace it.
HS blower motor
There are two relatively recurring malfunctions concerning the blower. The brushes are damaged. The more time passes, they will be able to deteriorate and produce electrical faults. The fan may run randomly, or may not work at all. It is also possible that the concern comes from bearings of the fan motor. If the ventilation hisses, comparable to a rusty mechanism, its bearings may lack lubrication. We invite you to comment on this guide in case your concern is different in order to help other readers. Good walk!
