Kia Sorento Second Row Seat Problem - Rear Seat Folding and Latch Repair

2011 Kia Sorento
2nd Row Rear Seat
Latches did not work to allow seat to fold down or fold up to allow a passenger to get in. So seat appeared stuck in upright position.
I videoed as I was investigating. It was a rather easy fix once I understood the cause, but you do need to partially remove the seat cover, or you can just try to remove the latch cover at the top of the seat and re-insert the cable housings into their groves. But it may come loose again.
I show my solution at the beginning, but then I threw in all the footage after so you can see how things work or are put together. You may have different issues, so I tried to describe how things work as I investigated.
