Do not confuse the air conditioning , heating and ventilation of this jeep compass. Heating and air conditioning are systems that offer the possibility of reducing or increasing the temperature of the air. The very first through the heat emitted from the engine block, and the other with the help of a liquid refrigerant . Your ventilation is all the ducts and mechanisms that allow the air to reach inside. The essential element is the kicker which emits the air within your passenger compartment. If little or no air is coming in, it is probably a ventilation problem. We will see in this guide how ventilation works, in order to be able to better identify the problems and understand how to solve them.jeep-compass-ventilation-problem

How does ventilation work on a jeep compass

The ventilation is first of all used to circulate the air in the passenger compartment of this jeep compass. As for the blower, the latter is generally made of a resistance, a turbine, and a motor. The lower the integral resistance of the electrical system, the faster the turbine turns. By turning the knob in the passenger compartment, the resistance is therefore reduced.

jeep compass: frequent ventilation problems

Dirty air ducts

If the ventilation turns on but very little air enters the passenger compartment of this jeep compass, it is possible that these air flaps are blocked. With the aid of screwdriver flat, you can remove the flaps from the air flaps. Just take a look inside if these are clogged. If this is the case you can scrub them, but also the shutters.

Dirty cabin filter

If you discern effluxes and this ventilation lacks intensity, the problem must probably come from the cabin filter of this jeep compass. This one gets blocked and piles up bacteria as time goes by. It is really normal that it is dirty, it serves to clarify the air that reaches us. There is no instruction from the manufacturer on when to change it. We only advise you to take it apart and check its condition. If it is ever completely clogged, it will be better to replace it.

Resistance of the blower HS

If ever the ventilation buttons on your Jeep Compass work badly, or really not, it is probably due to resistance. This resistance is used to increase the voltage to amplify the speed of this turbine. A suspicious malfunction of this ventilation is undoubtedly due to a problem of resistance. This electronic chip is complicated to repair. It will have to be replaced.

HS blower motor

We can find two rather recurring problems with the kicker. Brushes may be worn. Over the years, these can wear out and cause false contact. The blower may operate randomly, or even no longer operate at all. It also happens that the problem comes from bearings of the fan motor. If ever the ventilation makes a high-pitched noise, like rusty mechanics, the bearings may need lubrication.
