REMOVAL & INSTALLATION
Remove all door inside handles.
Remove the door inside locking rod knob.
On styles with door pull handles, remove the screws inserted through the handle into the door panel.
On styles with remote control mirror assemblies, remove the remote mirror escutcheon and disengage the end of the mirror control cable from the escutcheon.
On styles equipped with switch cover plate in the door armrest, remove the screws securing the cover plate, then disconnect the switches and cigar lighter, if so equipped, from the harness connectors.
Remove the remote control cover plates and remove the exposed screws securing the cover plate to the door inner panel.
On styles with integral armrest, remove the screws inserted through the pull cup into the armrest hanger support. On some styles it may be necessary to remove the screws behind the armrest deflector or courtesy lamp remote control cover plate. On styles with armrest applied after the door trim installation, remove the armrest to door inner panel attaching screws.
On styles with with two piece trim panels, disengage the retainer clips at the front and rear of the upper trim panel. Remove the upper trim panel by lifting upward and sliding slightly rearward to disengage the the front door inner panel at the beltline.
On styles with electric switches located in the door trim panel, disconnect the wire harness at the switch assembly.
To remove the lower trim panel, remove the attaching screws along the upper edge of the lower trim panel. Then starting at a lower corner, insert a pry type tool between the door inner panel and the trim panel and disengage the retaining clips down both sides and across the bottom. On styles with courtesy lamps or reading lamps located in the trim panel, disconnect the wire harness at the lamp assembly.
On styles with one piece trim panels, remove all the clips around the perimeter of the trim panel. Push the trim panel downward and outboard to disengage it from the door inner panel at the beltline. Disconnect any courtesy lamp wire harnesses, if so equipped and remove the trim panel from the door.
Installation is the reverse of removal. On styles with adjustable trim supports at the beltline, the door trim panel can be adjusted in or out so as not to restrict door window operation.
Once you get that panel off, look for linkage rods going to the latch from the lock mechanism. They are held into the latch by small cheap plastic clips. If one breaks, you will have this problem. Part is dirt cheap and sold in an assortment of different sizes for a few bucks.

Sounds like the power actuator may have quite in that door but you'll have to follow Nick's instructions to access it.
