Hey guys,
First time posting but wanted to contribute after this thread helped me out of this frustrating situation.
I personally went on ebay and bought a tested and guaranteed door actuator from a wrecker for $50.
Note: Before I started I disconnected the battery... Probably unnecessary but didn't want to risk it.
The door trim was easy enough to remove... 5 Phillips head screws around the perimeter, one Phillips head under the arm rest and a torx screw hidden behind a small plastic cover where the interior door latch is.
Carefully pop the trim along the bottom of the door (gently use a flat blade screwdriver to pry the lugs in the trim free) and pull door up and off.
The trim will be attached to the door by the two wire cables from the latch to the door actuator I recommend taking a photo of these connected to the latch and remove the trim out of the way because it's annoying.
Peel the plastic back near the actuator.
Unclip the plastic clip holding the rod to the actuator.
Take a photo of the two wire cables connected to the actuator and then remove by awkwardly pulling the wire out and around in an s shaped movement (the wire cable ends are shaped like an S)
Remove the 3 torx screws holding the actuator to the door and pull the actuator out so you can see it.
Remove the wiring loom by gently sliding a flat blade screwdriver between the red plastic clip and the black plastic body (see photo). The red clip will gradually slide upwards away from the body and the wiring loom will disconnect from the actuator.
Now twist the actuator around to get at the exterior door latch rod. This is awkward and takes a bit of fiddling to twist it off.
Remove the actuator from the car and replace with the new one. Follow the steps above in reverse to install.
I've attached photos of the key components to give you an idea.
Hope this helps someone.
