I'm confused, my windscreen wiper is playing games with me 
It pull the stork down to intermittent and nothing happens, pull it down again and works(fast) . It goes back to intermittent and it works. To stop the wiper arm in correct place, I have to time it right otherwise it can come to rest anywhere on the windscreen.
What is causing it? and what would you check first?
Thanks
