Question: Bad Lock Actuator, or something else???

I recently purchased my 2005 T&C Touring from a dealer. At the time of purchase the power locks did not work. I replaced the battery in the key fob, disconnected the battery cables, removed/visually inspected/reinserted all fuses then reconnected the battery cables and the power locks all work except the driver-side rear slider. Both rear doors and hatch are all power open/close and all work with interior buttons and key fob EXCEPT this driver-side slider. It seems no power is getting to it at all, however it is very easy to manually unlock and open (no resistance) and all visible parts (track, chain-like wire housing, etc...) are all in like-new condition. The previous owner took exceptional care of the van, obviously and per the CarFax report there has been no accident damage. My question is: could a bad actuator be responsible for my problem, or should I be looking at a different culprit? I have learned this is a very common issue for this model/year, but prior to replacing this part I, of course, want to be sure this will fix the problem. As a result of the power lock not working I am unable to activate my anti-theft alarm, also, which is very disconcerting to me. Thanks for any assistance and advice in advance.
