Hi all,\ngot an astra with a rear wiper that isn`t working. I checked that the fuse\nis ok, and it is. I checked that electricity is present when the switch is\npressed to operate the rear wiper - it is. I`ve tried getting a new motor\nassembly, pulled from a working rear wiper and no joy. Have I missed\nsomething really obvious that would fix the rear wiper?\n\nThanks for your help!
