Under these switches one can find relatively ingenious systems. Ingenious, but sometimes non-functional! Because it's a problem we've all had, on a Renault Juvaquatre or any car. But before replacing the mechanism, you will have to understand what the problem is. A contact problem? Are the gears stuck? We will try to answer all your questions here.Renault-Juvaquatre-window-problem

Renault Juvaquatre: a window goes down but does not go up, or the reverse

Before replacing the component, let's just study how this device works. When you press or lift the button on the famous window, there are two switches in practice . The electrical signal passes just when you activate it. It is therefore possible that the problem is due to an electrical fault. Remove the part using a flat screwdriver, then observe the cables at their beginning and at their end. If the problem is not the result of a bad contact, then it is the window regulator motor of your Renault Juvaquatre which is HS. It is also possible that the gears are damaged. Do not hesitate to try to correct the problem, but often the entire window regulator must be replaced.

Renault Juvaquatre: A single window does not work at all

It is rare for the problem to be with the switch, since both switches or cables would have to be faulty at the same time. However, you can control whether you want to be convinced of it. The problem may therefore come from the mechanics of the window regulator of your Renault Juvaquatre. It may be that this comes from engine window regulator, or a faulty gear. Remove the door trim to examine the interior. Activate the window to be able to see if the engine is running, and try to understand the causes of the problem. When gears get stuck, don't hesitate to clean and lubricate them. When nothing happens, you will likely need to change the entire window mechanism.

Renault Juvaquatre: Electric window blocked

A window of this Renault Juvaquatre is blocked. You try to raise it by pressing the button or by hand, nothing to do it gets stuck. This problem can come from the motor of the window regulator, but often it will be possible to reassemble it by hand. It is therefore much more possible that the glass has come out of its rail . By decentring, when you raise the window, the latter hangs on one side. In this case, there is no point in forcing anything. It is necessary to clear the door and look at what is blocking inside. If ever the window guides prove to be broken, you will probably have to replace them.

Conclusion:

To put it simply, a window problem on a Renault Juvaquatre can come from a problem related to a poor contact, the window regulator system, or the rails that guide it.
