I had been looking for a wiper blade refill for the drivers side of my 2003 Sonata for a few months. The book and all computers say it needs a 22 inch blade, and I know from experience that it must be narrow. . Its impossible to find a 22 inch narrow refill. I must have bought and returned a half dozen in my quest. Finally the other day I was in Advance Auto and found a
21 inch narrow refill. On the back of the plastic pack was a inch ruler imprinted and I saw that the blade was really 21 and a half inches long. So I decided to see if it would work. When I put it up to the OEM blade, it was exactly the same length. They lie!! The OEM blade is 21 and half, not- So save yourself a lot of time and trouble and just buy the 21 1/2 inch refill. Yes, I know that I could have replaced the entire blade assemble but those are all bigger and bulkier that I like the looks of. bill P.S. I had also earlier found a 21 and half inch refill, but it was not narrow.
