You don't have to do anything to the motor. the regulator and motor are one piece that go in together.
First you have to take the door panel off...
Just take out the screws on the top sides of the panel and the screws behind the grab handle. Then you should be able to lift the panel straight up and over the door lock ****.
Next you need to disconnect the cable from the latch...
I think you may have to disconnect the door lock too but I can't remember. if you do - it's not that hard to figure out.
Once the door panel is off, you have to separate the window part from the door part.
Then, once the window portion of the door is removed, you can take out the regulator itself.
Remove the circlip (#2 in photo) and unscrew bolts #6 and #11.
It's really pretty easy to see how the window regulator goes on.
hope this helps
