Every late 80s to early 90s GM car I've been in, the seats fold forward to access the back seat without having to do anything. They all have a black plastic latch sticking out like your supposed to lift it to release it to fold. I've been thinking of replacing my hinge but I want to be sure it's actually broken. Is that what that latch is for? Did it ever work? Does anyone's seats lock upright?

 

All my 3rd gens with OE seats & 4th gen seats, have all locked into place. If yours doesn't, the latch is broke.

 

I guess I'll be ordering replacements.

 

Mine is broke also, both seats.

 

I swear it seems like every part I try to get for this car is discontinued

 

They're supposed to be an intertial latch like you expect.

 

One good thing is companies are starting to have more aftermarket oem style parts for our thirdgen cars just as they have done for earlier years.
