How do you undo the J hook on the back of the driver's seat of a Chevy Tahoe?
I used a little pick to get mine undone, it was a pain but once you start it goes easy
The 2004 Chevrolet Tahoe has hook-end wiper arms. Press a little tab where the wiper blade is inserted into the hook. Then pull the wiper blade out of the hook. Be sure to purchase the correct replacements first by looking up your vehicle in the wiper blade books at the store or lookup wiper blade size online. Below are some videos - watch the videos for U-Hook arms.
