This is driving me mad!!! I have replaced the wiper arm today and the relay, no difference (even taken the rear mechanism out and really greased it)! it seems to be out of sequence, like it does 90% of a cycle each time , so the rear wiper ends up in different positions each time!!
I think at some point a previous owner has tried to to the lay flat trick, but messed it up!
Can some please, pleaser, please take a pic of there rear wiper mechanism inside the car so i can see the postions of the arms, i should be able to put it back to normal from that.
Cheers
