We have a 2001 V70 and the rear wiper doesn't come on when requested. However, it is parked, the fuse is fine, and when I've fiddled about with it/slammed the tailgate / forced the wiper out of park it has sprung into life a bit, and returned to park.
From googling this group I'm suspecting the wires that get bent every time you open & close the tailgate are failing, but any other ideas of likely suspects? Or sensible diagnostics?
TIA
