Do not confuse the air conditioning , heating and ventilation of your Opel Omega. Heating and air conditioning are systems that will decrease or increase the temperature. The first with the help of the heat generated by the engine block, and the second with the help of a fluid refrigerant . The famous ventilation is all the circuits and devices that allow air to reach the interior of the vehicle. The fundamental component is the kicker which propels the air into your vehicle. If the air comes in very little or not at all, it is probably a malfunction of ventilation. We will see within this text how a ventilation works, so as to better identify the concerns and assimilate by what means to resolve it.ventilation-problem-Opel-Omega

How does ventilation work on an Opel Omega

First of all, ventilation is used to circulate the air inside the interior of your Opel Omega. Regarding the blower, it is generally composed of a resistor, a turbine, and a motor. The lower the total resistance of the circuit, the faster the turbine operates. By turning the knob in the passenger compartment, the resistance is therefore reduced.

Opel Omega: frequent ventilation problems

Dirty air ducts

If the ventilation turns on but little air arrives in the interior of your Opel Omega, it is possible that the air shutters are clogged. Using a screwdriver flat, do not hesitate to remove the air shutter covers. It is only necessary to check inside if these are blocked. When it is the case do not hesitate to scour them, as well as the valves.

Dirty cabin filter

If you ever perceive fumes and this ventilation lacks intensity, the malfunction certainly comes from the cabin filter of your Opel Omega. The latter clogs and piles up bacteria with the years. It is completely normal that it is dirty, it is there to purify the air which reaches you. There is no manufacturer's instruction on when to change it. We just advise you to remove it, check its condition. If it is particularly black, it will have to be replaced.

Resistance of the blower HS

If ever the ventilation settings of the Opel Omega do not work well, or not at all, it is certainly due to the resistance. The resistance used to raise the voltage to increase the speed of the turbine. A strange functioning of this ventilation is undoubtedly linked to a resistance malfunction. This little microchip is difficult to troubleshoot. It will have to be replaced.

HS blower motor

We can find several rather recurring concerns about the kicker. The brushes may be damaged. The more time passes, they can be damaged and generate false contact. The kicker will be able to work very randomly, and even not rotate at all. It is also possible that the malfunction comes from bearings of the motor. If the ventilation ever makes a hissing sound, like a rusty mechanical, its bearings may require lubrication.
