405 auto lift windows


Recommended Posts

The wiring loom isn't the same with automatic window, I don't have it but here is a tutorial in french:

There is another way to do this, with another PSA control box (Xantia, Partner...) and the regular switch.

I did this on my 309 for both front windows. For the passenger side it's the ony easy way to do so.

It can also be used in a lot of other cars.

Thanks for the diagrams. Are these now for the Xantia box? I have the 405 control box 6555e8 coming from Germany.

Do you have any idea about the operating principle of these boxes, are they basically just measuring the current draw of the lifter motor?

The 405 (mk1, mk2) or BX control boxes are 8 9 pin, the extra 2 are for the automatic action with a special switch.

The boxes are mesuring the current to stop the motor but only the 6 pin ones can detect a short or a long push and react accordingly.
The 8 9 pin boxes are more basic and need more complex switches. On the mk1 405 you can see the automatic part of the switch, on the mk2 it's hidden but still there.

Mk1 and mk2 405 boxes are not the same bdw.

The wiring loom on my 309 is still stock, you could also do it like that on the 405 with a 8 9 pin module but only for the driver side.
On the passenger side I even used diodes to find a ground on the switch connector and not having to take it somewere else (when the driver is operating the passenger window there is one wire at 0v and the other at 12v).

9 pin not 8!

Yes no point splicing the original loom, this can be done with additional connectors etc.

Now I got the parts. Switch similar to 406, soft push for manual operation and harder push for automatic opening. Basically it has two different outputs for both open/close directions. The control box is to be actually 9 pins and it does not seem easy to figure out the connections.

I finally had some time to play with the control box. I found out that Haynes manual surprisingly has this wiring diagram for ph1 but it is lacking the important information about the pin numbers. That 605 instruction helped a lot. Connection seems to be identical.

9-pin control box / psa part 6555.E8:

Top row pins A1-5, bottom row B1-5:

  • A1: window lifter motor
  • A2: ground
  • A3: blank, no pin here
  • A4: other wire for window lifter
  • A5: +12V feed to box
  • B1: touch ground for auto movement
  • B2: touch ground for auto movement
  • B3: +12V feed to box
  • B4: keep grounded for normal movement, direction same than pin B2
  • B5: keep grounded for normal movement, direction same than pin B1

I did not list the actual directions, that depends which way the lifter motor is wired. Although this seems to work, use at own risk. I did not fry the box or car yet. :lol:
