Rear Door Wont Open From Inside

[DACIII]

Sorry in advance for the long post just want to cover everything. A couple months ago I replaced my door speakers in my truck and after putting everything back realized a flashing yellow light for my child safety lock when my truck starts. Now my truck rear drivers side door wont open from inside it opens from outside. I believe the door thinks its on child safety mode but i don't know. I took the panel off the door this weekend and when I take the cable out for the handle I can turn child safety on and off no problem usually it would blink if i turned it on. I then pulled the cable with my hand where the ball is and I could hear the door engaging  so then I closed the door and got in and pulled the ball and the door opened. I figured out when i put the cable back attached to the door is when it doesn't want to work but,  I put the door panel back on and tried again and it worked so then I drove out of garage and got my wife to try to open door from outside so she pulled handle and it wouldn't open even though the truck was unlocked so then I hit child safety and then it went back to doing the blinking again but then allowed her to open door but then it went back to not allowing exit from inside.

have you tried the little switch/toggle on the door jamb that wont allow the door to open from the inside?

Which switch are you referring to? I have inserted pictures of the door jam and a video of what the truck is doing.

I apolgize.  Was washing my truck today and realized the toggle I was referring to is not present.  I was thinking of my wifes pathfinder.  Again, my apologies.

I am having the same issue.  I have a 2014 silverado LT. The child lock blinks when the truck is switched on and the rear driver door will not open from the inside. I switched the truck on and pressed the child lock button and it quit blinking, allowing me to open from inside. Then I pressed the button again and it won’t allow me to open from the inside and it’s back to blinking. I have pulled the door panel, fuses, scanned for any codes and everything checks out.  I am absolutely stumped and I really don’t want to take it to the dealer. Can anyone help me?
