Each seat back unlocks properly when a door is opened or the release
button
on the side of the chair is pressed, but the linkages will not move by
themselves into the locking position (although they will stay there
once I
slide the hooked lever into place). Is it possible there is a problem
in
the locking circuit only?
There is no unlocking 'circuit', it's spring-loaded, much like the
fuel flap. Either both sides got equally sticky (not!) or there
is a small leak getting started that's siphoning off just enough
vacuum to prevent it from working right. Getcher MityVac out!
