Hi. I recently got my '94 hatchback and I noticed that the rear wipers need replacement. So my dad and I went to Concord to buy new blades but the technician said that with my car, I cannot just replace the blades, but I have to replace the whole arm. Is this true? If yes, does anybody know where I can buy a replacement wiper? If no, can anybody please teach how to replace the wiper blade? Im a newby car owner and seems pretty complicated. Thanks!
