Let's not confuse the air conditioning , heating and ventilation of the Jeep Wagoneer. Heating and air conditioning are devices that offer the possibility of decreasing or increasing the air temperature. The very first through the heat emitted by the engine block, and the second using a fluid refrigerant . Your ventilation is all the circuits and systems that will allow air to reach the interior of the vehicle. The main component is kicker which emits air into your vehicle. If there is very little or no air, it is probably a malfunction of ventilation. We will discover within this file how ventilation works, so as to better identify malfunctions and understand how to remedy them.
How a ventilation works on a Jeep Wagoneer
Ventilation is primarily used to circulate the air inside the passenger compartment of the Jeep Wagoneer. For the blower, the latter is usually composed of a resistor, a turbine, and a motor. The lower the integral resistance of the circuit, the faster the turbine runs. By turning the switch in the passenger compartment, the resistance is lowered.
Jeep Wagoneer: frequent ventilation problems
Dirty air ducts
If the ventilation works but very little air reaches the interior of the Jeep Wagoneer, it is conceivable that your air shutters are clogged. Using a screwdriver flat, do not hesitate to remove the covers from the air vents. It is only necessary to take a look inside if these are clogged. When this is happening do not hesitate to dust them, as well as the valves.
Dirty cabin filter
In case you discern fumes and this ventilation is weak, the malfunction probably comes from the cabin filter of the Jeep Wagoneer. It clogs and accumulates bacteria with the years. It's really normal that it is dirty, it is used to purify the air that reaches you. There is no recommendation from the manufacturer as to when to replace it. It is simply advised to dismantle it, check its condition. If it is really black, it will be better to change it.
Resistance of the blower HS
If the Jeep Wagoneer's ventilation buttons are not working properly, or even not at all, it is probably due to the resistance. This resistance increases the voltage to increase the speed of the turbine. A strange functioning of this ventilation is probably linked to a resistance malfunction. This microchip is complicated to troubleshoot. It must be changed.
HS blower motor
There are several rather common malfunctions on the blower. The brushes may be worn out. Over time, these can be damaged and produce false contact. The pulser can rotate randomly, and even not activate at all. The malfunction may also come from bearings of the motor. If the ventilation produces a hissing sound, comparable to a rusty mechanism, it can happen that the bearings lack lubrication.
