Easiest way is to grab the round bar that runs across the underside and twist it forward. There is a tab you push and then twist, you may not have to push the tab, I can’t remember and my Jeep is 3k miles away!
It is behind and toward the transmission tunnel side of the seat adjustment (forward/rear) pull bar. It is what the cable running from the upper pull tab actuates to release the seat.
Still no fix. I have tried different things and nothing works long term. The bike cables and the cable at Lowe's break. Most people will sell a seat but not just that part.
