I know this is an old thread, but I, too, am a new owner of a 1994, and I had the same question about seat swiveling until today. My seats don't say flexsteel anywhere, so perhaps they aren't the same as others have, but I think they are original to the van. The swivel lever is on the left hand side of the seat (not on the arm), and it was just freely moving without any action. Under the seat, I found a cable that is attached to that lever, but the other end was just lying on the carpet. To restore swivel action to the passenger seat, the only tool needed was a pair of needle nose pliers. Under the seat you'll see a spring and a plate with a small hole. Use the spring to give you the freedom to reach the hole with the cable end, then feed the z-shaped end of the cable through the hole in the mechanism with the pliers. Voila--seat releases and swivels over the floor-mounted seat belt (which might be the culprit that sometimes knocks the cable-end out of its hole) to face the rear, and you've got a sociable living room.
