Yeah I had the same problem once. I bet they are the double bladed type that look like the strangest pair I've ever seen, or they aren't the right type or something. I went to my buddies at NAPA and got replacements for pretty cheap. Under 15 bucks. Basically look in the manual or just ask the guy at the computer for any auto parts store and he'll get you the right stuff. If that doesnt work then something is out of wack with the arm base thingy. What is the part that holds the arm called anyway?
