Earlunas Fallo Peugeot 306

I have a problem with the windows of a Peugeot 306 have stopped working and looked at the fuses and they are fine but when disassembling the keys of the driver's door and proven that light does not arrive.
Remove the door connector and Nor does Luz arrive, someone can tell me how the connector is changed, that is, the piece that goes from the car to the door if it can be or if it can be of a relay I have no idea the electronics surpasses me.
thank you

The problem is in the cables that enter the connector any sete a cut you can get the Coxe connector and try to weld with tin although they are very braces

Depending on the year of Peugeot, they are equipped with a command unit called BSI that is the one that controls almost everything electric, but for that problem you have you can do a separate installation the problem is that it could explain it completely but nesecitas of electronics to be able to reaise it

A door connector wiring repair kit is sold. Asked in a Peugeot service

The 306 have no BSI
