The rear auto lock works fine. The side door does not. I was just assuming that maybe it didn't have an actuator. I'll pull the panel and see what I can find out.
Yes... check the actuator. But also check relay or fuses as it may be possible each door has separate ones... where I was leaning to with my original question is that if the rear wasn't working also, it may be that the side and rear were deactivated, as this is possible to do via the ignition switch and dash buttons... see owner guide for steps.
My 08 is having the same problem. Had Dodge dealer put in new latch to no avail (worked for 1 day). In cold weather lock to unlock will not change state and vice versa. In varying degrees, other locks affected as well. In my view of possible problems 1) Something sticky and getting stickier in colder weather changing timing issues with body control module, 2) Misalignment somewhere of latch/door, 3) Sticky switch in gear change mechanism. I would fix myself, but our 08 is under warranty.
There is a wiring harness in a flexible plastic tray that rides along with the slider door as it opens and closes if we're talking about an NCV3. Mine was completely missing when I bought my truck. My experience with some domestic minivans that use this style of wire loom is the wires can break and give you intermittent or inoperative all together door lock function. Check under the plastic step panel after opening the side door.
