Do not confuse the air conditioning , heating and ventilation of the Jeep Cj7. Heating and air conditioning are devices that offer the possibility of reducing or increasing the temperature. The very first thanks to the heat produced by the engine, and the other using a liquid refrigerant . The famous ventilation is all the circuits and mechanisms that allow air to get inside. The main component will be kicker which sends air into your vehicle. In the event that the air arrives very little or not at all, it is certainly a concern of ventilation. We are going to see through this file how a ventilation works, in order to better discern the problems and assimilate how to solve it.problem-ventilation-Jeep-Cj7

How a ventilation works on a Jeep Cj7

The ventilation is primarily used to regenerate the air inside the passenger compartment of the Jeep Cj7. Regarding the blower, it is generally made of a resistor, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine operates. By turning the knob in the passenger compartment, the resistance is therefore reduced.

Jeep Cj7: frequent ventilation problems

Dirty air ducts

When the ventilation turns but little air arrives in the passenger compartment of the Jeep Cj7, it is conceivable that these air flaps are blocked. Thanks to a screwdriver flat, do not hesitate to remove the air shutter covers. Just look inside if they are crowded. When this is the case, do not hesitate to clean them, but also the shutters.

Dirty cabin filter

If you ever smell odors and this ventilation lacks power, the problem probably comes from the cabin filter of the Jeep Cj7. The latter clogs and piles up bacteria with time. It is really common that it is dirty, it serves to clarify the air that reaches you. There is no instruction from the manufacturer as to when to replace it. We simply advise you to disassemble it, check its condition. When the latter is particularly black, it will need to be replaced.

Resistance of the blower HS

When the Jeep Cj7's ventilation controls malfunction, or even not at all, it is probably due to the resistance. This resistance increases the voltage to increase the speed of this turbine. Inconsistent operation of this ventilation is probably due to a concern for resistance. This microchip is difficult to repair. It will have to be replaced.

HS blower motor

There are two fairly regular problems with the kicker. The brushes may be damaged. Over the years, they can be damaged and generate electrical faults. Your fan may run very randomly, and may not even run at all. It also happens that the concern comes from bearings of the motor. When the ventilation makes a sharp noise, like a rusty mechanic, its bearings may require lubrication. Do not hesitate to comment on this file when your concern is different to help Internet users.
