Xsara Picasso 2.0HDi rear wiper problem.

[omas]

Hi, I've got problem with my rear wiper. It's starting on it's own whenever I'm unlocking central lock, putting reverse gear on and sometimes when I open boot or doors. It sometimes starting to work as it should for a few days and then problem comming back. I repaced rear wiper motor, checked earth, cleaned up comm2000 modul and wiper switch in stalk. I've seen on some foreign forum bsi reboot can help, but I have not idea how to do it and to be honest I'm afraid I can broke bsi if I will start messing up with it. Does anyone know how to fix it?

Ost likely that your tailgate wires are frayed and shorting, pull back the umbilical tube between the tailgate and roof, and chek the wires inside.
