two door sport - rear seat won't unlatch.

What is your question?

Any tricks in getting the rear seat to unlatch to fold down? Seat use to latch and unlatch fine, but I folded it down and loaded a bunch of weight on it. Then folded it up and now the seat won't unlatch. Cables seem brand new, in tact, and operating. I can't see the latch to manually unlatch it or spray wd-40. Shaking while pulling the handle does not work either.
