What is it with all these threads about wipers at the mo? Anyhow, this is serious <img src="http://www.mbclub.co.uk/iB_html/non-cgi/emoticons/hmmm.gif" border="0" valign="absmiddle" alt=':hmmm:'> Having gone up the M1 in heavy rain today, which justified full speed wipers, I now have a problem. In any mode of operation, when my wiper moves it makes a loud noise. It sounds like the motor is straining and a bit like a food blender!! When I reached my destination in Yorkshire, in an attempt to stop iminent failure (it sounds bad! ) I used spray on grease on the exposed mechanical bits. Did not help, but made me feel better. The wiper still actually works but makes me cringe. So does anyone have experience of this or know how to fix? Is there anything i can take apart to look at or oil? Looking on the dark side, how much is a new wiper motor?
