Hi all, new to this today. I have a wiper problem on my 2007 110. Wipers just seized as I was pulling on to the drive earlier. No movement whatsoever. I checked fuses etc & all ok. Checked the wiper spindles & cleaned them up a bit & they moved about 1/2, hardly any force used. Turned them on again & they work but the sweep across the screen is now different to normal & there is a clunking sound each time they sweep across the screen. Any ideas how to remedy this? Thanks in advance.
