I have a damaged windshield wiper arm. I would like to replace it myself but I am unsure how to go about doing this. Any advice you might have would be appreciated.
You should be able to pop the cap off at the pivot point. You may need to use the edge of a flat blade screwdriver. Once you have carefully removed the cap, you will see a retaining nut (generally 13mm). Remove the nut by turning your ratchet counter-clockwise. Remove the windshield wiper arm. If it does not slide off easily you will need to use a battery terminal removal tool to finish the removal. DO NOT use a pry bar or you may damage the glass windshield. The tool can be purchased online :
