I posted this for my MS3 a few years ago when I owned one. I need to change out the Mazda6 wiper blade for my P5 as well and probably will try this method if I can (when I stop procrastinating). Hope this helps in some way:
I've seen from time to time members posting questions about replacing the rear wiper. I for one actually like the option of using it during rainstorms, but some folks don't like it as much and have done the rear wiper delete mod.
At first, all I saw were members saying that you can only get the replacement from Mazda, which for some folks is inconvenient since the dealer is far away, and it also costs a pretty penny for such a simple item. Ordering online isn't a great option due to shipping...unless you order other things and just add it to the list of things you're purchasing.
So I went to my local Advance Discount Auto and purchased two rubber blades (for around $5 or so) that you can cut down to size. Make sure they have the two metal strips since you cannot use the metal strip from the OEM rubber blade. You may be able to find a rubber blade at your local auto parts place that looks like the stock one, but I couldn't.
EDIT* Other owners have reported that you can go to AutoZone and buy a Duralast 14" wiper for $7. Then all you have to do is remove the blade from the Duralast arm and slide it into the stock rear wiper arm. Or you can buy Duralast refills from Autozone for $4.99 for a pair of them. No metal needed either, it's already got hard plastic on top of the blade that slides right into the stock rear wiper arm. You can buy a longer version of this and cut it down too.
NOTE: There's a section in the owner's manual (section 8-30 to be exact or page 297. Here's the
PDF version) on how to change out just the blade part of the rear wiper.
Onto the process and pics. So first take off the entire rear wiper:

Cut down the new blade and the metal strips to match the stock one:
Seat the metal strips to the new rubber blade (the metal strips can be finicky to keep the slots/grooves, so be patient):
Next, slide the blade into the wiper slot (start from the 2nd slot on one side and work your way to the other end - leave the very end slot open for now):
In this pic, I am working the blade from right to left:
Leaving the last slot open - then you bend the blade and the metal strips a little to fit it in:
Re-attach the blade to the wiper assembly now:
And you're done! Congrats...and now enjoy clean streak-free wipes!!! :wiggle:
