Let's not confuse the air conditioning , heating and ventilation of your Citroen Traction 15. Heating and air conditioning are devices that lower or increase the temperature. The first thanks to the heat emitted by the engine, and the other with the help of a liquid refrigerant . Ventilation is all of the ducts and devices that allow air to enter the passenger compartment. The fundamental element is the kicker which sends air into your cabin. In the event that the air arrives very little if not at all, it is certainly a problem of ventilation. This guide will show you how ventilation works, so that you can better identify problems and understand how to fix them.
How does ventilation work on a Citroen Traction 15
Ventilation is primarily used to regenerate the air in the interior of your Citroen Traction 15. 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 switch in the vehicle, the resistance is therefore reduced.
Citroen Traction 15: usual ventilation problems
Dirty air ducts
If the ventilation turns on but a small amount of air arrives inside the cabin of your Citroen Traction 15, it is likely that the air shutters are obstructed. Thanks to a screwdriver flat, you can remove the air shutter covers. You just have to check in if they are blocked. If this is what is happening you can clean them, but also the valves.
Dirty cabin filter
If you smell fumes and the ventilation is poor, the problem must probably come from the cabin filter of your Citroen Traction 15. The latter clogs and piles up bacteria with time. It is really normal that it is dirty, it serves to clarify the air which reaches us. There is no manufacturer's recommendation as to when to replace it. It is advisable just to remove it, look at its condition. If it is completely black, it will have to be changed.
Resistance of the blower HS
If the Citroen Traction 15's ventilation control ever works poorly, or even really not, it's probably due to the resistance. This resistance used to raise the voltage to increase the speed of this turbine. A suspicious ventilation malfunction is probably due to a resistance problem. This microchip is difficult to troubleshoot. We will have to change it.
HS blower motor
There are two fairly regular problems with the kicker. The brushes can be damaged. Over the years, they can be damaged and cause electrical faults. Your fan may run very randomly, or may not work at all. It also happens that the problem comes from bearings of the fan motor. If ever the ventilation produces a hissing sound, comparable to a rusty mechanical, it happens that its bearings lack lubrication.
