2003 Saturn L300 Replacing Wiper Blades

If there the orignal refills they tear then they will slide out if they have been replaced there will be two tabs to squeese and u can slide them out just don't let go of that spring loaded wiper arm or it will break ur windshield.then u just slide in the new refill and lock it in place.or u can replace the blade which is the holder and refill that just has one tab to slide it in.ur choice which u want to do most of them have instructions in the package.good luck let me know how it goes.
