I have a 2005 Dodge Stratus 4-door, X engine, which is exhibiting the problem where all electronic locks function except the front driver's. Replacing the door lock actuator did not fix the issue, and so now I'm looking to trace the voltage behavior from the latch back to the BCM.
I could really use some advice if I'm going about this the wrong way, or if others have insight into what the crux of the issue might most likely be.
Feeding the actuator is a 4-wire harness with Black, Tan, Blue+White, and Orange+Black. Putting a volt meter on the wires shows that the tan wire is 12v on latch open.
If anyone has the correct voltage readings for the Blue+White and Orange+Black wires on lock/unlock positions, I'd appreciate it if you would share. I'm getting readings that aren't in line with what I read off of the corresponding Pink/Lght Blue, Pink/Black counterparts on the front passenger door actuator's wiring harness.
To recap - I'd greatly appreciate
*) anyone pointing out a better diagnostic strategy or something that I'm overlooking
*) or affirmation that this is the right process to detect the cause.
*) a definitive reading that I should be getting from the front driver's side actuator harness on door lock/unlock switch positions.

I should have also mentioned that the behavior that the car exhibits is that of a dead actuator. There is no audible "click" from the actuator in any lock switch position. Holding the actuator in-hand while connected to the wiring harness also produces no sense of internal movement on lock/unlock. Which is why I am pursuing it as an electrical issue.

How about a continuity check from either the kick panel or BCM to the actuator, I'm guessing a broken wire in the feed where it leaves the car body and enters the door.

I have the Stratus back in the garage this weekend and I'll be following the electrical back from the actuator to see where things are going wrong.
What I observe presently is that both the Blue+White and Orange+Black wires are showing +12v on unlock and ground on lock with closed latch. My understanding is that one should be showing +12 on lock/Gnd on unlock and the other Gnd on lock/+12 on unlock (like the passenger side is reading).
For now, the door rubberized cover is off, the steering column lower panel is off, and I have a clear path identified for the wiring from the BCM to the actuator.   Will update.

Solved!
In the rubber boot between the door and the frame, the orange+black wire had been worn to the point where it had cracked+separated. Two other wires in the collection were on the verge of breaking in the same manner.

If you get one window, lock, speaker fail, always look to the loom going from body to that door first.
Glad to help.
