@MrBiggs228, it sounds like these are the second row bucket seats, right?
FWIW, if they're like my '04's, the release for the seat back is a mechanical lever on only the outboard side of the seat, with no linkage to the other side. It has a coil spring on the shaft, behind the trim piece, so maybe that's broken or has come loose. That spring returns the latch and handle to the lock position when you let go of the lever. Looks like you could take the plastic trim piece off with one Phillips screw to get to it.
There is one cable on mine, and that releases the headrest when folding down the seat back. Nothing to do with releasing the seat back.
