How to Remove the Arms?
Now that you are equipped with tools, you may begin by removing the old arm first. Make sure that the control switch is in 'off ' position. Look for a cover at the bottom of the arms, which houses the attachment bolt for each wiper. Remove this cover, to expose the underlying bolt. Using the appropriate size socket, remove the bolt and place it somewhere carefully. After the bolt is removed, the arm will come off, with some effort.
