My experience a broken wire in the wiring that goes between the tailgate and the body.

Try lubing the mechanism. I fixed my Corolla’s stuck hood latch with a little wd40 to clean it up, followed by a little motor oil. it worked so well on the Corolla that I did the same on my truck. I didn’t realize how hard to use the truck’s hood latch had become over time. Now it is smooth as silk.
