Do not confuse the air conditioning , heating and ventilation of this cherokee jeep. Heating and air conditioning are mechanisms that will decrease or increase the temperature. The first with the help of the heat emitted by the engine block, and the second with the help of a liquid refrigerant . The famous ventilation is all the ducts and mechanisms that allow the air to reach the interior of the vehicle. The fundamental component will be the kicker that emits air into your vehicle. If the air is coming in very little or not at all, it is probably a ventilation problem. Thanks to this file, we will see how ventilation works, in order to better identify the dysfunctions and understand how to resolve them.problem-ventilation-jeep-cherokee

How a ventilation works on a Cherokee jeep

The ventilation is first of all used to regenerate the air in the passenger compartment of this Cherokee jeep. As for the blower, it is generally made of a resistance, a turbine, and a motor. The more the total resistance of the electrical system is lowered, the faster the turbine runs. By turning the switch in the vehicle, the resistance is therefore reduced.

jeep cherokee: usual ventilation problems

Dirty air ducts

If the ventilation works but very little air is getting into the passenger compartment of this Jeep Cherokee, it is possible that the air flaps are blocked. Thanks to a screwdriver flat, do not hesitate to remove the valves from the air flaps. It will suffice to look inside if these are obstructed. If this is what happens, do not hesitate to scrub them, as well as the shutters.

Dirty cabin filter

If you smell fumes and your ventilation is poor, the problem is probably with the cabin filter of this Jeep Cherokee. It clogs and piles up bacteria with time. It is quite common that it is dirty, it is there to clarify the air which reaches us. There is no manufacturer recommendation for when to replace it. We simply advise you to remove it, check its condition. If the latter is really dirty, it will be better to change it.

Resistance of the blower HS

If the ventilation buttons on your Jeep Cherokee are not working well, or even really not, it is certainly related to the resistance. The resistance allows to increase the voltage to increase the speed of this turbine. A bizarre malfunction in your ventilation is most likely due to a resistance problem. This electronic chip is difficult to troubleshoot. You're going to have to change it.

HS blower motor

There are several fairly common malfunctions with the kicker. The brushes are damaged. The more time passes, the latter will be able to wear out and produce electrical faults. The blower could operate haphazardly, or even stop activating at all. It could also be that the problem is with bearings of the motor. If ever the ventilation makes a sharp noise, like a rusty mechanism, it is possible that its bearings are lacking in lubrication.
