Did we talk previously about this on the forum? I remember your name. I believe we both were looking for help with our power door locks. Well luckily I fixed mine! Just got home from doing my strut and wheel hub job so i'll edit this post in 10 mins with detailed instructions.
The actuator/motor which you need to replace is actually screwed on by 3 small screws on to that black part which is in the middle left of the door(middle right for you). My mistake was thinking that I needed to replace the entire thing.
The black piece with the actuator attached to it is what all the rods lead up to. it will be kind of buried. Basically look at your door latch (outside of the door where the lock actually locks on to the at) and that is where the piece is.
Save yourself the headache. In order to get to those screws you MUST undo the clips connecting the rods to the actuator. If you don't you will not be able to move the actuator enough in order to unscrew it. There should be 3 I believe. 1 up to the actual door lock that leads outside, a second that goes to the door handle, and a 3rd that is your inside lock.
The goal here is to be able to move the actuator around enough to reach the small screws through the door latch. Once the screws are removed there is a small rubber arm that is placed inside a little boot on the piece the actuator is screwed on to. So don't look for screws if its still hard to get off after the three screws. Just play with it a little.
Its rough. Your wrists will be sore and it will probably take some time. Personally I hope i'll never have to do it again but it can be done. Put the new part in, make sure the arm is back into the boot or else the motor won't lock/unlock the door. Put the 3 screws in first, through the latch as well. Then reassemble the small clips that hold the rods together.
If you need more detailed pictures or even pictures just let me know. I actually have my old door lock actuator sitting 5 feet from me
