Under these switches there are quite ingenious systems. Ingenious, but sometimes defective! Because this remains a problem that we have all had, for a Citroen Sm or any automobile. But before replacing your system, you will need to properly understand where the malfunction is coming from. Contact malfunction? Gears seized? We will try to answer all of the questions with this article.
Citroen Sm: a window goes down but does not go up, or vice versa
Before replacing the part, let's quickly study how this device works. When you press, or raise the switch on your window, there are two switches in practice . The electrical connection goes only when you activate it. It is therefore conceivable that the problem originated from a false contact. Remove the part with the help of a flat screwdriver, and inspect the cables when they leave when they arrive. If the malfunction should never come from an electrical fault, in this situation it is the window lift motor of your Citroen Sm that is HS. Gears may also be in poor condition. You can try to fix the problem, but usually you will have to replace the entire window regulator.
Citroen Sm: One window does not work at all
It is not frequent that the malfunction comes from the button, because it would be necessary that the two switches or cables are defective at the same time. However, you will be able to control if you wish to be convinced of this. In this situation, the malfunction could come from the window regulator mechanics of your Citroen Sm. It may come from engine window lifter, or a faulty gear. Remove the door covers to check inside. Operate the window to discern if the engine is running, and try to understand the source of the malfunction. In case gears get stuck you can dust and lubricate them. In the event that nothing happens, it will certainly be necessary to change the mechanism of the window regulator in its entirety.
Citroen Sm: Electric window blocked
A window of your Citroen Sm is blocked. You try to raise it by pressing the switch or manually, nothing to do it is blocked. This malfunction can come from the motor of your window regulator, but usually it will be possible to have it mounted manually. It is therefore more plausible that your window has come out of its rail . When moving, when you mount your window, the latter abuts on one side. In this case, there is no point in forcing. You will need to clear the door and check what gets stuck in it. If the glass guides ever prove to be faulty, you should certainly replace them.
Conclusion:
To summarize, a window malfunction on your Citroen Sm can be the result of a malfunction linked to a false contact, of the system of your window regulator, or of the rails which hold it. You can leave us a comment if your problem is not mentioned above. Hope this text has helped, see you soon!
