It still could be a bad actuator. There is a "unlock detection" wire at each motor latch that letrs the ECU know if its already locked/unlocked.

Try manually locking/unlocking each door without using the switch a few times and see if they come to life. A bad keyswitch on outside of the door could be causing an issue also. They should all lick turning the key to lock and unlock turning it twice. You also have rear gate keyswitch also.

I'll flip them manually when I get a chance to.

I just parked and my doors locked fine with the key fob. I think it's interesting that power seems to be unavailable to the door locks 10 seconds or so after turning the car off...it seems to be less if the air conditioner fan is on... (maybe drawing more current from the system...) I've noticed if it's on, by the time I get out of the vehicle and close the door to lock it, I can't use the remote to lock the doors. Then I have to turn the key back to the on position, turn off the fan, turn the key off, close the door...and then I can lock the doors (if I do it quickly).

I flipped all the door locks manually and tried resetting the power again. Fuses look good. I've looked at diagrams, but don't know if there's a relay involved here that's got a bad power leg. Most of what I've seen makes it appear the wires go to the ECU and back out again. I can't seem to tell if there's a simple relay involved.

I was able to find an online service manual for this model and can't find what I'm looking for in the documentation. It's not looking good. I was really hopeful I'd find someone to say, "ohh yeah....it's this!" I'm starting to lose hope.

Ok....new symptom. I was outside and noticed the open door light was on. I went around and opened/closed all the doors (minus the lift gate because it won't open due to the door lock power issue)...but I verified all doors were closed prior to opening and closing them.

I put the key in the ignition and powering it on and off cleared the light. I'm wondering if one of the doors could be sending something bogus to the ECU?
