How to dismount the windows button on a 412

Hi Guys,

Long time I didn't post here but I still own my 412. In fact, I did not use my 412 for a long period, just doing the minimum to keep it in good condition.

Since a few weeks, I have fun again using the car so I am back here !!

By the way, the question of the day is : how to close the right windows of the car as the button do not seem to be working on the up side. And the sub-question is : is it possible to dismount the button without dismounting all the central console.

If someone can give me some advice before I start that would be of great help.

Many thanks.

eventually I tried to remove the button but I stopped as it doesn't look like you can remove it easely from above and I don't want to break anything.

So I just used the mechanical backup to close the window and I will ask a real professional take care of the problem.

Thx.

That was one of my idea but as I did find the crank to close manually the window I prefered not to try to hard. I am going to make (pay for !) some restauration on the car this fall including the change of the leather of the dashboard wich has shrinked, I think that the button will more accessible when the dashboard will be removed.

 

Hi Ken,

Thank you for the advices. I will try.

And yes it goes down but not up. For me it is 100% electrical not mechanical (I had a mechanical problem on the left window so i know how it looks). The motor does even try to move when I push the button. I really believe it is the button, if I can unmount it it I will be able to know if I am right.

As for the restauration I will post pictures ! But I am not going to make a full restauration. The car is in an overall good condition, just some cosmetic things like a repaint (but a good one). After, between what you went for and what you finish doing, there is always a difference with that kind of car

Ok, so I indeed got it by removing the ashtray. In fact what I didn't understood is that only the central part (the moving part not the frame) of the button that pops out.

Now I have opened the button and, for me, there no electronics, it's just a mechanical button.

2 options :

1. the button as a bad contact (faux contact in french)
2. the truth is somewhere else

I did test the button

The button has 5 pins from front to back :

Pin 1 => switch out for up
pin 2 => light+
pin 3 => switch enter
pin 4 => light-
pin 5 => switch out for down

The buttom seems to work fine.

Went back to the car to try the button (my hope was that maybe I did repair the bad contact without noticing it) => no chance, it still does not work.

So I tried the left button on the right window => it works => the problem is the button.

I went back home, and tested it with a voltmetre not only a led => no difference between up and down.

I am clueless but as I am not an electronic ingenior - even if I can understand the basics - there has to be something that I miss here.

Thanks Ruben.

The only thing I saw being able to explain the behavior was an intensity problem. So I cleaned the contacts and ... know it works !

For information, the button is very easy to dismount/remount.
