Same problem as me one month ago. It is jammed and dirty inside, needs to go to the garage to dismantle the wiper etc. to clean and put on greese . Go to LUJIAN for 60$ or <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-comffice:smarttags" /><st1:City><st1:place>FUJI</st1:place></st1:City> 80$
