Suburban Barn Door Stuck

Any ideas much appreciated.
Suburban barn door stuck. When certain tail lights won t fit the suburban with barn doors it means they were not made for that vehicle or they are defective. The door is installed by holding it at a 45 degree angle and lowering the top edge until it meets the window gap. The rear passenger door the driver side door and the barn doors in the back will not lock or unlock because the actuators have failed. Then it is pressed together until the plastic clips sap closed.
It is snapped down then simply swings into place. After that the pieces like door handle arm rest and speaker and grill cover are installed using screws. Crawl in back and remove lower carpeted panel of passenger side barn door. They give a little nudge when you push the button but nothing happens.
Follow the connecting rod to where it attaches or should have been attached to the outside handle and activate by hand. The rear barn doors were discontinued on the suburban in 2005. I saw your one answer from earlier and not sure what trim to remove. I tried the key on the back and it does nothing.
