I swapped my driver's door a couple of weeks ago, and don't remember this being too difficult...
If i remember correctly there is a rod from the pump to a plastic clip that slides onto the lock mechanism. My clip may have been broken, so came off easily. Then there's another rod from the clip to the door lock pin (in fact the door lock pin screws onto the rod).
Vac pipe pulls off but needs a fair tug.
Then two screws and out.
