Let's not confuse the air conditioning , heating and ventilation of this Jeep Comanche. Heating and air conditioning happen to be systems that will lower or boost the air temperature. The first through the heat generated by the engine block, and the second using a fluid refrigerant . Ventilation is all the channels and systems that allow air to enter the passenger compartment. The fundamental component will be the kicker which sends air into your automobile. If the air is coming in very little or not at all, it is probably a ventilation malfunction. Thanks to this file, we will see how ventilation works, so as to better identify the problems and understand how to solve them.problem-ventilation-Jeep-Comanche

How a ventilation works on a Jeep Comanche

The ventilation is primarily used to regenerate the air in the passenger compartment of this Jeep Comanche. For the blower, it often consists of a resistance, a turbine, and a motor. The more the total resistance of the electrical system is lowered, the faster the turbine operates. By turning the switch in the passenger compartment, the resistance is thus reduced.

Jeep Comanche: frequent ventilation problems

Dirty air ducts

If the ventilation is running but very little air is coming into the passenger compartment of this Jeep Comanche, it is plausible that the air flaps are blocked. Using a screwdriver flat, you can remove the air vent covers. It will suffice to take a look inside if they are blocked. If this is the case, you can scrub them, but also the shutters.

Dirty cabin filter

If you perceive fumes and your ventilation lacks power, the malfunction is probably from the cabin filter of this Jeep Comanche. This one gets blocked and piles up bacteria with the years. It remains completely normal that this one is dirty, it is there to filter the air which reaches us. There is no recommendation from the manufacturer for when to change it. It is simply advisable to take it apart and check its condition. If this is completely black, it will be necessary to change it.

Resistance of the blower HS

If the ventilation knobs on your Jeep Comanche are not working properly, if at all, it is most likely resistance. The resistance is used to increase the voltage to boost the speed of the turbine. Poor performance of your ventilation may be linked to a resistance malfunction. This small electronic chip is complex to troubleshoot. It is necessary to change it.

HS blower motor

There are two fairly common problems with the kicker. The brushes may be damaged. The more time passes, they will be able to wear out and generate false contact. Your fan may run very randomly, or not run at all. It is also possible that the malfunction is the result of bearings of the fan motor. If the ventilation whistles, like a rusty mechanism, it is possible that its bearings are lacking in lubrication.
