Please help me, one of my back door is not unlocking when all others door are unlocked.

No safety locks were ever placed on my back doors. I know how to do it, but I never did it. The behind my driver seat will not unlock at all. Does any one has any suggestions? Thank you in advance.

Resetting the electronics may resolve this. There is a particular fuse to pull (Google for it), or you can disconnect the battery briefly. If that doesn't work, then the latch assembly on that door is defective or there is a wiring problem.

This happened to me once on my 2013 3.8 Sedan — and to the exact same door you mention (rear passenger behind driver). Like you, I checked the safety switch — which wasn't the cause. Interestingly, what seemed to work in my case was starting the car—then shutting it off and locking it using the key fob.

A few minutes later, I used the key fob to unlock all the doors (two pushes)—and voila! It worked again and has ever since.

It's worth noting that I first tried the above method using the door buttons (only) and it didn't work… But using the key fob did. No idea why, but now both the door and key fob work perfectly well (though now I've probably jinxed it).

Though from what I've learned reading posts, what works for one doesn't always work for others. Part of the charm—or curse—of technology. Best of luck!
