latch

Hey, Y'all. I have a 1981 GL500. I've been able to remove the rear seat in the past without any trouble. Recently I tried the usual method, but one of the helmet lock handles seemed to travel much further forward than usual, almost like a spring had broken. Also, no audible "ping" sound like in...

Swapped out the trunk back to the second seat on my GL500 went to switch back and the right side helmet lock arm flings all the way up when unlocked. There is no tension to the arm to release the lock. Not sure how to fix the issue or get at it. Any advice?
