Door will not LOCK - Fob, switch or manually??

I have '13 Tundra Crew Max. My driver side rear door will not lock. If I use the fob or the controls on the front driver or passenger door you will hear the doors lock but then that driver side rear door will immediately unlock. I was thinking actuator is bad. But the odd thing is I cannot manually lock either. The flip switch by the door handle is like almost jammed in the middle so cannot flip to unlock or lock. ANY IDEAS???

Thanks!!!

 

Not sure the cause but you will likely need to take off the interior door panel to review the linkage between the various pieces. Does it actually move at all with the actuator or move and then move back?

 

This happened last night so going to have to look today and see. You can definitely hear the locking noise and then 1 second later hear it unlock. Now whether it's actually moving or not I'll have to look. The confusing part is the flip switch by the door handle not moving. I called the dealership and he was that was weird that the manual lock didn't work, thought maybe something was jammed inside the panel. May take panel off this weekend and see if there is anything obvious.

 

I've replaced the actuator motor twice (Different doors) in my daughters 4runner. I can't remember if she could lock it manually or not but maybe that will help.
I bought a 4 pack of the motors on Amazon.
