Jeep Rear passenger door issues

Hey guys. So my rear passenger door on my 09 unlimited X is locking electronically but not unlocking. I already looked at the wiring harness and it is tight. I assume something is wrong with the door handle, but I wanted to get some advice before I start taking things apart. This door also has a broken bushing which I do plan on replacing once the new bushings come in. THanks for the help.

Really close to being finished with my wishlist:

*highrock 4x4 front bumper
*2 sets of hella black magic lights
*2" rancho 9000xl sports lift
*Trek Armor seat covers
*Rugged ridge floor mats
*Pavement ends rear bumper
*Trek Top NX
*Insulation for hardtop
*Grab handles
*Console cover
*Daystar dash organizer
*Daystar A pillar switch module

Just need:
and then probably more things

It is probably the lock actuator. My previous truck had the same problem in reverse. It would unlock via the switch just fine, but it wouldn't lock. I had to lock it manually, which was annoying until I turned off my auto unlock all with ignition turn off feature.

Just saying it happens, and can affect the actuator in only one direction.

No. That is aftermarket. I'd want to know it'll work as the factory replacement with the OEM harness. You might try moparonlineparts. They are a vendor here.

I had problems with the auto lock actuators when my battery was dying out. Once replaced everything returned to normal.

My door sometimes will randomly work. So maybe it is something wrong with the battery. Should I just try unplugging the negative end for ten minutes and see if a reset helps it out?

ECU reset might work, if not you might have a local auto parts store load test your battery before you start buying new lock parts.

The OEM Chrysler batteries are fairly poor quality. Low crank amp and short lived.

I've had good luck with Sears Platinum series and Odysseys.
Both have glass mat construction and high amperage.

THanks for the help. But my issue is that it moves slightly when it unlocks and locks however it does not fully engage. Does anyone have any pictures of what the actuators actually looks like or where to connect a multimeter to to see if the actuator is bad or if its an electrical connection?

I had this same issue with my 09 Ram. After 3 Mos. of trying figure this out. Had to take it to the dealer. It was the (door module) the black box that the door lock actuator, mirror, and door lock/unlock switch plugs into went bad.

DO you remember how much this cost you? I would like to do this myself but it seems like its semi challenging to do. I just hate bringing stuff in and paying a crap load of money.
