How do you change the wiper blades on a 1994 Chevy Corsica?

I'm sure this is a very easy process but I can't seem to figure out how to remove the old ones to be able to put on the new ones.How do you change the wiper blades on a 1994 Chevy Corsica?
lift the wiper arm up. where the blade is attached to the arm will be a black plastic fitting. there will be a button on the bottom of the fitting. push that button and it will release the blade from the arm. if you cant get it, go to a parts store and they will replace them for you, and pay attention to what they are doing so next time you can do it all by yourselfHow do you change the wiper blades on a 1994 Chevy Corsica?
