I have not liked the auto windscreen wipers on my Oct.2003 156 4 door Selespeed. I would much rather just have a delay even if it were fixed to just one. Recently, if on delay or if you ask for just one wipe or auto wipe with wash, the wipers do not complete their stroke but finish a few inches short. This prevents any forther wiping unless the wipers are turned on to normal or fast. It is so annoying that I have bought another car to drive until I can get something done. Has anybody any adviced please.
