Hi. I have an Alfa Romeo 147 Lusso. I have recently had problems with the windscreen wipers which now pass over the windscreen and on to the side of the frame of the car which is causing some nsty scratches. It looks as though the base of the windscreen wiper has cracked from the holding panel. If i got the whole unit replaced then I'm sure it's going to be very expensive. Any ideas/suggestions? Has anyone had this problem before? Thanks in advance for the advice.
