The wipers on my 155 have decided to be 'eccentric'! Sometimes they work ok, other times they are somewhat erratic and go at different speeds depending on the day and sometimes stop mid flow! I have also noted they only appear to have an adjustable intermittent speed of flat out and nothing in between (and the stalk only appears to have these 2 positions). Is that normal???
Is the problem likely to be the motor....and if so, how difficult is it to change? Its not a dashboard out job is it?
