I would first try lubricating everything related, latch and pin. I would also make sure that the cable is not getting "in the way" of things or something else in the hinge area or another area on the right side causing pressure where it shouldn't. If none of that is the problem then I wouldUpdate……. Tailgate open. Have to raise the handle and push on the passenger side of the tailgate and it will open. Not sure why this is happening. Any suggestions would help. Thanks.
