my rear wiper is stopping too low down for some reason(just catching the boot lid!) feels as if the arm has worked loose on the motor. how do i go about tightening it back up, i ask because i cant seem to get the cap off!! thanks in advance
best way to get the wiper arm off is to lift up the blade and arm when you have removed the bolt asif you were washing your car, then using the blade /arm lift it up and down wiggleing it till it comes off always worked on loads a wipers for me.
