My rear wiper started peeling away from the blade, so I replaced it with one I had bought a few months ago. In case you haven't replaced the rear wiper, it's very easy. You pull it away from the window and rotate the wiper back until it comes off the arm. Replacement is a reverse of this procedure. BUT - make sure the two little pips are lined up with the two indents on the wiper arm.

By the way, both the front and rear of the 2015 Fit use 14" blades, but they're different! Very strange. Luckily, I picked the correct one first.

 

One of the things I learned on the first day I bought my PBP EX was if you put it in reverse with your windshield wipers on is the rear wipers, work automatically. ..They collect dirt and debris too so I make sure I clean it regularly.

 

No need to replace the whole blade. You can simply replace the rubber insert. If you can find one. Honda will sell you one but it is probably rather expensive. It is a standard 6mm square (as opposed to trapezoidal) rubber strip. They used to sell these in parts stores; I can't find them anymore.
