They have been making a funny noise for a while, like a more distinct "click" when starting a sweep from rest.
But today they (BOTH) seem to have jumped a cog as they come to rest quite a bit further up the screen than usual and when running the driver's side one clouts the upright edge of the winscreen surround quite hard on each sweep.
Although in this state, they seem OK, I don't trust them not to suddenly let go.
Is it possible that the linkage could have jumped a cog on the motor?
All help most gratefully received and thanks in advance.
