:great: Trying to save others some time, money, stress & headaches... There is an alternative to going to the dealer for a replacement rear wiper blade on the 07+ Chevy Trailblazer. It may first appear that the blade and arm are one piece but if you take a look, you'll see the wiper blade can be replaced and its actually quite simple. It's a special rear wiper blade though. There may be other alternatives, but the "Trico Exact Fit Rear Integral Blade" snaps right onto the special rear arm and looks like the factory original. You can find it online. Much cheaper than the dealer alternative and easier/less tedious than messing around with rubber blade refills. Comes with removal and replacement instructions too. Hope this helps.
