Let's not confuse the air conditioning , heating and ventilation of the Renault Kadjar. Heating and air conditioning are systems that will decrease or increase the temperature. The very first by means of the heat generated from the engine block, and the second with the help of a liquid refrigerant . Ventilation is the totality of channels and mechanisms that allow air to reach the interior of the vehicle. The fundamental component will be kicker which propels the air into your automobile. If there is little or no air supply, it is probably a ventilation problem. We will see in this file how a ventilation works, so as to better identify the problems and understand the technique to solve it.problem-ventilation-Renault-Qajar

How does ventilation work on a Renault Kadjar

The ventilation is primarily used to circulate the air in the passenger compartment of the Renault Kadjar. Regarding the pulser, it is often composed of a resistor, a turbine, and a motor. The lower the total resistance of the circuit, the faster the turbine turns. By turning the knob in the vehicle, the resistance is thus reduced.

Renault Kadjar: common ventilation problems

Dirty air ducts

When the ventilation works but little air reaches the interior of the Renault Kadjar, it is conceivable that the air flaps are blocked. With the aid of screwdriver flat, you can remove the valves from the air vents. Just take a look in if they are clogged. When this is the case you can dust them, but also the valves.

Dirty cabin filter

When you perceive effluxes and this ventilation lacks intensity, the concern must undoubtedly come from the cabin filter of the Renault Kadjar. The latter clogs and accumulates bacteria as time goes by. It remains quite common that it is dirty, it is used to filter the air that reaches us. There is no manufacturer's instruction as to when to change it. It is only advisable to remove it, check its condition. When the latter is really black, it will be necessary to change it.

Resistance of the blower HS

When the ventilation buttons on the Renault Kadjar do not work well, if not really, it is probably linked to the resistance. The resistance used to increase the voltage to increase the speed of the turbine. A strange functioning of this ventilation is probably linked to a concern for resistance. This microchip is complex to troubleshoot. It must be changed.

HS blower motor

There are several rather recurring problems with the kicker. The brushes are damaged. Over time, these can deteriorate and generate electrical faults. Your kicker may work in a haphazard manner, and may not even operate at all. It also happens that the concern comes from bearings of the motor. When the ventilation whistles, comparable to a rusty mechanism, it can happen that the bearings lack lubrication.
