hi,i always pull the arm up from the windscreen and pull the wiper blade down.they should be pretty straight forward.if the clips break you local car shop should stock them.just take the old one with you.also ir you lift the wiper arm up and pull towards you this will take the whole arm and wiper off.they are only pushed on and arent bolted to the motor.they are like this on my aircooled and should be the same on the bis.hope this helps. :wink:
