Do not confuse the air conditioning , heating and ventilation of the jeep wrangler. Heating and air conditioning are mechanisms that can lower or increase the temperature. The very first thanks to the heat produced by the engine, and the second using a liquid refrigerant . Ventilation is the totality of ducts and devices that give the possibility of air to reach inside. The essential element will be kicker which sends air into your vehicle. In the event that the air hardly or not at all arrives, it is probably a concern for ventilation. We will see in this file how a ventilation works, to be able to better discern the dysfunctions and assimilate the technique to regulate it.jeep-wrangler-ventilation-problem

How a ventilation works on a jeep wrangler

The ventilation is used to start circulating the air in the passenger compartment of the jeep wrangler. 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 operates. By rotating the switch in the passenger compartment, the resistance is therefore reduced.

jeep wrangler: frequent ventilation problems

Dirty air ducts

If the ventilation ever turns but a small amount of air arrives in the interior of the jeep wrangler, it is conceivable that the air flaps are obstructed. Thanks to a screwdriver flat, you can remove the covers from the air vents. You just have to look inside if they are clogged. If this is the case you can scour them, but also the shutters.

Dirty cabin filter

In the event that you feel effluxes and your ventilation lacks intensity, the problem probably comes from the cabin filter of the jeep wrangler. This clogs and accumulates bacteria as time goes by. It remains completely common that it is dirty, it is there to clarify the air that reaches us. There is no manufacturer's recommendation as to when to replace it. We only advise you to disassemble it, check its condition. If it is particularly dirty, it will have to be changed.

Resistance of the blower HS

If your jeep wrangler's ventilation controls ever work poorly, or not at all, it's probably related to resistance. This resistance increases the voltage to amplify the speed of the turbine. A bizarre malfunction of your ventilation is probably due to a concern for resistance. This little electronic chip is complicated to repair. It is necessary to change it.

HS blower motor

There are two relatively regular malfunctions on the blower. The brushes are worn. Over the years, the latter may deteriorate and generate false contact. The fan may run randomly, and may not even activate at all. It also happens that the concern comes from bearings of the fan motor. If the ventilation whistles, comparable to a rusty mechanism, its bearings may lack lubrication. We invite you to comment on this file if your concern is different in order to help Internet users.
