How do you replace the rear wiper on a Kia Sportage?

I do not see a rear wiper listed in the aftermarket application guides for 2005 or newer so if you're asking about one of those years, it appears to have a special Kia wiper and you'll have to ask your dealer when you purchase the replacement since you'll have to go there for the wiper.

The 1995-2002 Kia Sportage has the most common hook-end wiper arms on front and back however. See sources and related links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.
