rear lock stopped working

[Denis]

Mmmmm Huw... pllzzzz ;-)   it s the first thing i tried. The switch is open
and i use my fingers to make the contact.... but nothing happen.

The vaccum line work well.

I ll look at the electro-pneumatic modul under the rear seat.
That  module can lock only if the main computer decide it if  the speed is
under 25km/h i guess....but the switch should be connected to  the rear
unit,,, i ll  see...

thanks Huw

Denis
