So I got my car fixed from a dent it had and for reasons i will never understand he took off the whole rear windshielf wiper......and put it back on wrong so now instead fo sticking up like this I it is like this - lol and it sure does look funny when I turn it on but it isn't that useful lol. So to fix it back do I just unscrew the base? I kindof tried already but didn't have the proper tool to fit it lol
