not sure if this will help you but i remember reading something inside my manual with resetting the rear gate. I can look into mine if you dont have one. but i would give that a try.
Looks like I have to buy a new lock mechinism. This is a dealer part and will cost some big money. easy to take out and install.
I have the same problem. Thanks anyway, I would have two of the same broken parts. Where did you get the new part and how much was it. Dealer gets $250. Thanks
