Passenger Power Door Lock Intermittent

[rog_ski]

Good Day

 

2006 Silverado regular cab (115000 KM) with power door locks and power windows

 

The Passenger side drive door lock has started to intermittently not work properly. Happens more in the cold -10 Celsius (windows - mirrors) all work properly

 

When you put it in gear it will lock the door and back in park it will unlock the door, if you hit the key fob to lock and or unlock it shows that it is working but the door remains locked. If you manually attempt to unlock the door from the inside or pull on the handle it stays locked. As if the handles (outside and inside) are disconnected from the door mechanism. Then when you're about to give up it works again and you can get the door open.

 

I have read through a number of posts going back years and its pointed to a actuator but the fact that you hear it and see it moving the door lock from the inside has me wondering if the mechanism is loose or worn. Or ... is this an actuator that needs to be swapped out?

 

Thanks in advance for any smarts you can pass on.
