Do not confuse the air conditioning , heating and ventilation jeep grand cherokee. Heating and air conditioning are devices which give the possibility of lowering or amplifying the air temperature. The very first through the heat produced by the engine, and the other with the help of a liquid refrigerant . Your ventilation is all of the ducts and systems that give the opportunity for air to enter the passenger compartment. The main element is the kicker which emits air in your automobile. If the air barely or not at all arrives, it is certainly a concern for ventilation. We will discover within this guide how a ventilation works, in order to better identify the problems and assimilate by which means to solve it.problem-ventilation-jeep-grand-cherokee

How a ventilation works on a grand cherokee jeep

The ventilation is primarily used to regenerate the air in the passenger compartment of the jeep grand cherokee. For the pulser, the latter is usually composed of a resistor, a turbine, and a motor. The more the integral resistance of the electrical system is reduced, the faster the turbine turns. By turning the knob in the vehicle, the resistance is thus reduced.

jeep grand cherokee: frequent ventilation problems

Dirty air ducts

If the ventilation ever turns but a small amount of air arrives in the passenger compartment of the jeep grand cherokee, it is possible that the air flaps are blocked. Thanks to a screwdriver flat, it is possible to remove the air flap valves. It is only necessary to check inside if these are blocked. If this is what happens it is possible to clean them, but also the shutters.

Dirty cabin filter

If you perceive odors and that the ventilation is weak, the concern undoubtedly comes from the cabin filter of the jeep grand cherokee. The latter clogs and accumulates bacteria with time. It is completely normal that this one is dirty, it is there to purify the air which arrives to us. There is no manufacturer's instruction as to when to replace it. We only advise you to remove it, look at its condition. If it is particularly dirty, it must be replaced.

Resistance of the blower HS

If the ventilation of your jeep grand cherokee does not work well, or even not at all, it is probably due to the resistance. This resistance increases the voltage in order to amplify the speed of the turbine. Inconsistent ventilation operation is probably due to a concern for resistance. This small electronic chip is complex to repair. It will have to be replaced.

HS blower motor

There are two fairly common problems with the kicker. The brushes may be damaged. The more time passes, they can wear out and produce false contact. The kicker can work very randomly, or not turn at all. The concern may also come from bearings of the fan motor. If the ventilation ever makes a hissing sound, such as a rusty mechanism, its bearings may lack lubrication. Feel free to comment on this guide if your concern is different to help our readers.
