I'm new to the forum world!
I noticed the problem yesterday, I unlocked my car and went to open the rear left passenger door to let my son in and it was still locked but the other doors were unlocked. I rolled my driver side window down and pressed the lock/unlock switch and all the locks would go up and down but, not the rear left passenger lock. The lock works when I push and pull it manually so I can open the door but, it wont work when using the switch. I also tried the front passenger switch to see if that would work but, the same all locks would go up and down except for the rear left passenger lock.
Has anyone else had this issue? If so how did you fix it, besides taking it to the dealer. Trying to save my money if I can do it myself.

Thanks in advance!

Welcome to the forum Alvin.

When you have a chance, head over to the Newbie Section and say "Hi".
Tell us a little about yourself and your ride.
That way we can welcome you all proper like.

Sounds like either a broken wire or the actuator is dead. When you press the unlock button does the lock pull pin move at all?

Thanks for responding! I checked into newbie section.
When I hit the unlock button nothing happens, the pull pin doesn't even budge. All the other doors function properly.

Hum, usually the lock will make some movement or sound if the actuator is on the way out. It may be a broken wire. Try locking/ unlocking it when the LR door is open, and part open.
Remember to not hit the lock/unlock buttons repeatedly. Give a little time between tries. The reason for that is; The relays are not the best, and you don't want to fry one because they are inside the TIPM (computerized fuse box), soldered on the circuit board.

All the lock/unlock circuits are tied together so odds are it is not a computer problem.
But, just for grins, try a reset in case it is a computer glitch. Disconnect the Neg(-) battery cable for 10 minutes.

I will give that a shot and see what happens. I'll keep you posted. Thanks

No luck on both things you suggested to do. The pin didn't budge when i had the door completely open or partially open. I disconnected the negative batt cable and re-connected it after 10 minutes, and nothing. I guess it could be a broken wire. That should be fun!!!!!

Does anyone here know how to test the wiring. I've taken the door apart before to replace the handle. (I'm having to do it a second time) So does anyone know how to expose the plug and all that jazz that works the lock......*Inhale*Exhale* Did I mention already that this should be fun....

One more thing, Is the pin pull resistance the same as the others?

In order to test the wires you will have to disconnect the harness that goes into the B pillar from the door. Then you can test continuity to the latch plug in. You may have to remove the B pillar inside trim to access it.
Before doing any work on the Nitro, disconnect the Neg (-) battery cable and wait 10 minutes!
This will allow time for the airbag capacitors to discharge.
You don't want to have your airbags go off accidentally.
It has already happened to a few members here...

There is a side impact sensor behind the B pillar trim!
