i have a 2000 honda accord coupe the guy at walmart told me i have to change the entire blade if i havent done it before because the factory blades i have wont let me just do the rubber insert refill. is this true? maybe it is because im having a hard time taking the rubber inserts off my blades, but im having an even harder time taking the entire blade off. can anyone give me good detailed instructions on how to remove the entire blade and replace it with the new one? or can anyone tell me if i can just replace the rubber inserts on my current factory blades? i tried removing the entire blade already, but it looks like i need some kinda of tool to loosen the bolts on the arm. im clueless....
