I have just bought a 406 1999 model year 110 HDi Estate, the front passenger window was not working, I have replaced the regulator mechanism, with a brand new one, it seems to go up but will not go down, I have had an auto electrician look at it, and he seems to think it is either an earth fault or the ecu for the windows, the switch on the left hand door is ok, does anyone know if the controlling electronics are in the drivers door switch console or is it a separate unit? Does anyone know where I can get a better wiring diagram from other than the Haynes one? The trim spec is GLX.
Thanks
Garth
